Background Art

[0002] With the advancement of battery technology, it is becoming increasingly popular to power electrical devices with batteries.

[0003] In some situations, a battery's external characteristics are easily affected by ambient temperature. For example, in low-temperature environments, the battery's capacity will decrease, preventing it from being fully charged, which in turn reduces its service life and effective capacity. Therefore, in some environments, it is necessary to preheat the battery to reach normal operating temperature.

[0004] How to heat the battery to meet the needs of normal operation is a technical problem that needs to be solved urgently in this field.

[0005] Summary of the Invention

[0006] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present application is to provide a method and device for regulating a battery regulation circuit, a method and device for controlling a battery, a method and device for monitoring a battery, an electronic device, a computer-readable storage medium, and a computer program product, so as to facilitate regulating a battery to meet the requirements for normal battery operation.

[0007] An embodiment of the first aspect of the present application provides a regulation method for a regulation circuit of a battery. The regulation circuit includes a power module and a battery side for connecting to the battery, the power module includes a bridge arm group and at least one inductor element, the bridge arm group is connected in parallel with the battery and includes a plurality of switching devices, the first end of each of the inductors is connected to the bridge arm group, and wherein the regulation method includes: determining whether to regulate the battery; and in response to determining that the battery is to be regulated, controlling at least the plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module, wherein the first current direction and the second current direction are opposite at the battery.

[0008] In the technical solution of the embodiment of the present application, by controlling the switching device in the power module, a current loop with different current directions is formed between the power module and the battery, so that the power module can be used to charge and discharge the battery, thereby realizing battery regulation (for example, pulse heating) to meet the requirements of normal operation of the battery.

[0009] In some embodiments, the bridge arm group includes at least one bridge arm, each bridge arm includes at least two switching devices corresponding to the plurality of switching devices, and the first end of each inductor element is connected between the two switching devices of a corresponding one of the at least one bridge arm. In response to determining that the regulation circuit is to be regulated, controlling at least the plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switching device of each bridge arm located on one side of the corresponding inductor element to be turned on and the switching device of the bridge arm located on the other side of the corresponding inductor element to be turned off, so as to form a current loop with the first current direction or a current loop with the second current direction between the battery and the power module. In this way, it is possible to ensure that the formed current loop passes through the inductor element in the power module, thereby utilizing the inductor element in the power module to charge and discharge the battery to achieve regulation of the battery (e.g., pulse heating).

[0010] In some embodiments, the at least one bridge arm includes a plurality of bridge arms connected in parallel, and the at least one inductor element includes a plurality of inductors, the second ends of each of the inductors being connected to one another. Controlling the switching device of each bridge arm located on one side of the corresponding inductor element to be turned on and the switching device of the bridge arm located on the other side of the corresponding inductor element to be turned off, so as to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switching devices of a portion of the bridge arms located between the corresponding inductor element and the first end of the battery side to be turned on and the switching devices of the portion of the bridge arms located between the corresponding inductor element and the second end of the battery side to be turned off, and controlling the switching devices of another portion of the bridge arms located between the corresponding inductor element and the second end of the battery side to be turned on and the switching devices of the other portion of the bridge arms located between the corresponding inductor element and the first end of the battery side to be turned off, so as to form the current loop with the first current direction; and controlling the switching devices of the plurality of switching devices that are turned on to be turned off and the switching devices of the plurality of switching devices that are turned off to be turned on, so as to form the current loop with the second current direction. The above-mentioned method first controls the upper bridge arm in part of the bridge arms to be turned on and the lower bridge arm to be turned off, and the upper bridge arm in another part of the bridge arms to be turned off and the lower bridge arm to be turned on, thereby forming a current loop with a first battery direction through the inductor element between the battery and the power module. Then, the switching device that is turned on is controlled to be turned off and the switching device that is turned off is controlled to be turned on, so that the current direction at the battery can be quickly changed by utilizing the hysteresis effect of the inductor element on the current change (that is, utilizing the continuous flow of the current at the inductor element), that is, quickly forming a current loop with a second battery direction. The above-mentioned embodiment makes full use of the hysteresis effect of the inductor element on the current change to quickly change the current direction in the current loop to charge and discharge the battery, thereby avoiding the inductor element from hindering the current commutation, thereby increasing the frequency of battery regulation (for example, pulse heating) and thus improving the efficiency of battery regulation (for example, heating).

[0011] In some embodiments, the regulation circuit further comprises a battery capacitor element, wherein the first end of the battery capacitor element is connected to the second end of each of the inductor elements, and the second end of the battery capacitor element is connected to the second end of the battery side. Controlling the switch device of each bridge arm located on one side of the corresponding inductor element to be turned on and the switch device of the bridge arm located on the other side of the corresponding inductor element to be turned off, so as to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switch device of each bridge arm located between the corresponding inductor element and the first end of the battery side to be turned on, and the switch device of each bridge arm located between the corresponding inductor element and the second end of the battery side to be turned off, so as to form the current loop with the first current direction; and at least controlling the switch device of each bridge arm located between the corresponding inductor element and the second end of the battery side to be turned off, so as to form the current loop with the second current direction. Through the above embodiment, a current loop through the inductor element and the battery capacitor element can be realized, so that the resonant effect of the inductor element and the capacitor element can be used to regulate the battery (for example, charge and discharge) to improve the efficiency of battery regulation (for example, heating).

[0012] In some embodiments, the multiple switching devices are power semiconductor devices, and at least controlling the switching device of each bridge arm located between the corresponding inductor element and the second end of the battery side to turn off to form the current loop with the second current direction includes: controlling all switching devices of each bridge arm to turn off to form a current loop with a third current direction between the battery capacitor element and the bridge arm group; controlling the switching device of each bridge arm located between the corresponding inductor element and the second end of the battery side to turn on to form a current loop with a fourth current direction between the battery capacitor element and the bridge arm group, wherein the third current direction and the fourth current direction are opposite at each inductor element; and controlling the switching device of each bridge arm located between the corresponding inductor element and the second end of the battery side to turn off to form the current loop with the second current direction.

[0013] After a period of time when a current loop with a first current direction is formed, the energy exchange between the battery and the capacitor elements in the power module causes the voltage of the battery capacitor element in the power module to be close to the voltage of the battery, which affects the resonance between the battery capacitor element and the inductor element, thereby affecting the pulse heating of the battery. Therefore, it is necessary to first turn off all switching devices so that the energy of the inductor element can be continuously circulated through the diode in the power semiconductor switching device in the bridge arm. Then, by controlling the lower bridge arm of each bridge arm to be turned on, the battery capacitor element charges the inductor element, thereby reducing the voltage of the battery capacitor element and changing the current direction at the inductor element. It can be seen from this that the above embodiment can, on the one hand, restore the resonance between the inductor element and the battery capacitor element, and on the other hand, after changing the current direction at the inductor element, use the hysteresis effect of the inductor element on the current change to quickly change the current direction at the battery, that is, quickly form a current loop with a second battery direction, thereby increasing the frequency of pulse heating and thus improving the efficiency of battery heating.

[0014] In some embodiments, the regulation circuit further includes a first control switch and a bus side for connecting to an external power source, wherein a first end of the first control switch is connected to a first end of the bus side, a second end of the first control switch is connected to a first end of the bridge arm group, and a second end of the bus side is connected to a second end of the bridge arm group. In response to determining to regulate the regulation circuit, controlling at least a plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling at least the first control switch to be turned off; and controlling the plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module. By providing the first control switch connected between the bus side and the power module, the first control switch can be turned off to disconnect the power module from the bus side before heating the battery, thereby enabling the power module to independently regulate (e.g., heat) the battery and preventing the external power source on the bus side from affecting the regulation (e.g., heating) of the battery.

[0015] In some embodiments, the regulation circuit further includes a second control switch and a third control switch, wherein the first end of the second control switch is connected to the second end of the first control switch, the second end of the second control switch is connected to the first end of the battery side, the first end of the third control switch is connected to the second end of each of the inductor elements, and the second end of the third control switch is connected to the second end of the second control switch, and wherein at least controlling the first control switch to be turned off includes controlling the first and third control switches to be turned off and the second control switch to be turned on. By turning off the first and third control switches and turning on the second control switch, the regulation circuit can be facilitated to enter a battery regulation (e.g., heating) mode. Furthermore, if a current loop for battery heating is implemented through the path where the third control switch is located, the current, after passing through the inductor elements, needs to flow back to the battery through the bus-side capacitor elements. This can cause circuit instability. Therefore, compared to turning on the third control switch, implementing a current loop for battery regulation (e.g., heating) through the path where the second control switch is located can prevent the current from flowing through the inductor elements before flowing into the bus-side capacitor elements, thereby increasing the stability of battery heating.

[0016] In some embodiments, determining whether to condition the battery includes: determining whether a condition instruction has been received, the condition instruction being used to instruct the battery to be conditioned; and determining to condition the battery in response to determining that the condition instruction has been received. This allows the battery to be conditioned (e.g., heated) as needed to meet normal battery operation requirements.

[0017] In some embodiments, the regulation method further includes: determining whether a stop regulation instruction has been received, the stop regulation instruction being used to instruct to stop regulating the battery; and in response to determining that the stop regulation instruction has been received, controlling at least all of the plurality of switching devices to be turned off to stop regulating the battery. Thus, battery regulation (e.g., heating) can be stopped as needed, thereby avoiding battery overheating or ineffective battery heating (e.g., continuing heating in the event of a battery failure or in the event of abnormal battery temperature rise), thereby increasing the safety of battery heating.

[0018] An embodiment of a second aspect of the present application provides a control method for a battery, comprising: obtaining status information of the battery, the status information including an initial temperature; determining whether the initial temperature is less than a first preset temperature threshold; and, in response to determining that the initial temperature is less than the first preset temperature threshold, sending an adjustment instruction to the adjustment circuit, the adjustment instruction being used to execute the adjustment method according to the first aspect of the present application. Thus, the battery can be adjusted (e.g., heated) as needed to meet the requirements for normal operation of the battery.

[0019] In some embodiments, the state information further includes state of charge and voltage. In response to determining that the initial temperature is less than the first preset temperature threshold, sending an adjustment instruction to the adjustment circuit includes: in response to satisfying a first preset condition, sending an adjustment instruction to the adjustment circuit, wherein the first preset condition includes at least one of the state of charge being greater than or equal to a preset charge threshold and the voltage being greater than or equal to a preset voltage threshold. This allows adjustment (e.g., heating) to be performed when the battery voltage and / or state of charge meet specific conditions, thereby increasing the efficiency of battery adjustment (e.g., heating).

[0020] In some embodiments, in response to a first preset condition being met, sending an adjustment instruction to the adjustment circuit includes: determining whether the adjustment circuit has a fault; and in response to determining that the adjustment circuit has not a fault, sending the adjustment instruction to the adjustment circuit. This allows the battery to be adjusted when the adjustment circuit has no fault, thereby improving battery adjustment safety.

[0021] In some embodiments, the control method includes: determining whether battery temperature rise status information has been received, the temperature rise status information including temperature rise abnormality information or temperature rise completion information; and in response to receiving the temperature rise status information, sending a stop adjustment instruction to the adjustment circuit, the stop adjustment instruction being used to execute the adjustment method according to the first aspect of the present application. This can avoid excessive adjustment (e.g., heating) or ineffective adjustment (e.g., heating) of the battery, thereby increasing the safety of battery heating.

[0022] In a third aspect, an embodiment of the present application provides a battery monitoring method, comprising: collecting current state information of the battery at a current moment, the current state information including a current temperature; and determining, based at least on the current temperature, whether to send heating state information to an upper-level controller, the heating state information being used to execute the control method according to the second aspect of the present application. This facilitates real-time monitoring of the battery's state, avoids over-regulation (e.g., heating) or ineffective regulation (e.g., heating) of the battery, and increases the safety of battery heating.

[0023] In some embodiments, determining whether to transmit heating status information to an upper-level controller based at least on the current temperature includes: determining whether the current temperature is greater than or equal to a second preset temperature threshold; and in response to determining that the current temperature is greater than or equal to the second preset temperature threshold, generating heating completion information as the heating status information. This facilitates real-time monitoring of the battery status and prevents overheating of the battery.

[0024] In some embodiments, determining whether to transmit temperature rise status information to an upper-level controller based at least on the current temperature includes: obtaining historical temperatures of the battery at historical moments; determining whether the battery temperature rises abnormally based on the current temperature and the historical temperatures; and, in response to determining that the battery temperature rises abnormally, generating temperature rise abnormality information as the temperature rise status information. This facilitates real-time monitoring of the battery status and avoids ineffective heating of the battery.

[0057] Currently, market developments indicate that batteries are increasingly being used. They are used as power batteries or energy storage batteries. Batteries are not only used as energy storage batteries in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used as power batteries in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0058] The present applicant has noticed that the external characteristics of a battery are easily affected by the ambient temperature. For example, in a low temperature environment, the capacity of the battery will decrease, making it impossible to fully charge the battery, thereby reducing the battery's service life and effective capacity.

[0059] In order to avoid the problem of reduced battery capacity, the applicant, after in-depth research, provides a regulation method and regulation device for a battery regulation circuit, a control method and control device for a battery, a monitoring method and monitoring device for a battery, an electronic device, a computer-readable storage medium, and a computer program product, so as to heat the battery to meet the requirements of normal operation of the battery.

[0060] The embodiment of the present application controls the switching devices in the power module to form current loops with different current directions between the power module and the battery.

The first end of each inductor element being connected to the bridge arm group may, for example, refer to the connection point of the upper bridge arm and the lower bridge arm of at least one bridge arm being connected to the first end of the inductor element.

[0065] Although FIG3 shows an example of a power module, the power module can be a module with any topology capable of regulating the voltage in the circuit. For example, the power module can select a non-multilevel topology (e.g., a structure in which the flying capacitors Cfly1, Cfly2, and Cfly3 in each bridge arm Q1, Q2, and Q3 are deleted from the power module 310) or a multilevel topology (e.g., the power module 310 shown in FIG3 (having flying capacitors Cfly1, Cfly2, and Cfly3), the power module 410 of the regulation circuit 400 shown in FIG4, and the power module 510 of the regulation circuit 500 shown in FIG5). In addition, the power module can also select a single bridge arm, a dual bridge arm (the two bridge arms in the power module 410 shown in FIG4), a three-bridge arm (the three bridge arms Q1, Q2, and Q3 in the power module 310 shown in FIG3), or more bridge arms (the multiple bridge arms in the power module 510 shown in FIG5), etc.

[0066] In some embodiments, as shown in FIG3 , the bridge arm group 330 of the power module 310 includes at least one bridge arm Q1, Q2, and Q3 connected in parallel. Each bridge arm includes at least two corresponding switching devices from a plurality of switching devices. The first end of each inductor element is connected between the two switching devices of a corresponding bridge arm from the plurality of bridge arms (i.e., connected to the connection point between the upper bridge arm and the lower bridge arm of the corresponding bridge arm). For example, taking the bridge arm Q1 as an example, the bridge arm Q1 includes at least two switching devices V1, V2, V3, and V4 from a plurality of switching devices V1, V2, …, V12, and the first end of the inductor element L1 is connected between the two switching devices V2 and V3 of the bridge arm Q1. The structures of the bridge arms Q2 and Q3 and the connection methods with the corresponding inductor elements L2 and L3 are the same as those of the bridge arm Q1 and will not be described in detail here.

[0067] It should be understood here that the number of inductive elements may be the same as the number of bridge arms. Alternatively, the number of inductive elements may be different from the number of bridge arms, for example, less than or more than the number of bridge arms. Specifically, one bridge arm may be connected to an inductive element, as shown in Figures 3 to 5. Alternatively, the bridge arm may not be connected to an inductive element, or may be connected to multiple inductive elements. The multiple inductive elements connected to the same bridge arm may be connected in series or in parallel, and the present application is not limited thereto. The first end of the inductive element may be connected in the middle of the bridge arm, that is, the two sides of the inductive element have the same number of switching devices. Additionally or alternatively, the first end of the inductive element may be connected between any two switching devices that are not in the middle of the bridge arm, that is, the number of switching devices on both sides of the inductive element is different.

[0068] In some embodiments, the plurality of switching devices V1, V2, ..., V12 may be controllable switching devices, such as contactors or power semiconductor devices. Power semiconductor devices may include devices such as IGBTs (Insulated Gate Bipolar Transistors), MOSFETs, and triodes. For example, as shown in FIG3 , the plurality of switching devices V1, V2, ..., V12 are power semiconductor devices, wherein each switching device V1, V2, ..., V12 includes a corresponding diode D1, D2, ..., D12. For example, the switching device V1 includes a diode D1. This allows current to pass through the power semiconductor device even if the power semiconductor device is in the off state when the current direction is consistent with the conduction direction of the diode.

[0069] In some embodiments, the inductive element may include an inductor or other devices that can store energy and provide a hysteresis effect on current changes.

[0070] In some embodiments, the regulation circuit 300 also includes a battery capacitor element C2, the first end of the battery capacitor element C2 is connected to the second end of each inductor element L1, L2, and L3, and the second end of the battery capacitor element C2 is connected to the second end of the battery side S2, that is, connected to the second end of the bridge arm group 310 (for example, the connection point of the lower bridge arm of at least one bridge arm).

[0071] In some embodiments, the regulation circuit 300 further includes a first control switch K1 and a bus side S1 for connecting to an external power source, wherein the first end of the first control switch K1 is connected to the first end of the bus side S1, the second end of the first control switch K1 is connected to the first end of the bridge arm group 330 (for example, the connection point of the upper bridge arm of at least one bridge arm), and the second end of the bus side S1 is connected to the second end of the bridge arm group 330 (for example, the connection point of the lower bridge arm of at least one bridge arm). As described above, the external power source can be a photovoltaic panel or a power grid, etc. The bus side S1 of the regulation circuit can be directly connected to the external power source, or connected to the external power source through the power conversion system 220 described in FIG. 2 .

[0072] In some embodiments, the regulation circuit 300 further includes a second control switch K2 and a third control switch K3, wherein the first end of the second control switch K2 is connected to the second end of the first control switch K1, the second end of the second control switch K2 is connected to the first end of the battery side S2, the first end of the third control switch K3 is connected to the second end of each inductor element L1, L2, and L3, and the second end of the third control switch K3 is connected to the second end of the second control switch K2.

[0073] Among them, at least one of the first control switch K1, the second control switch K2, and the third control switch K3 can be a controllable switching device such as a contactor or a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) tube. As shown in Figure 3, if only the first control switch K1 and the third control switch K3 are turned on, the external power supply and the battery will be connected together through the power module 310. At this time, the power module can play its voltage regulation function and regulate the voltage transmitted between the external power supply and the battery. In addition, if only the second control switch K2 is turned on, the battery will be disconnected from the external power supply. At this time, a current loop can be formed between the battery 230 and the power module 310 by controlling the switching device in the power module 310 to heat the battery, which will be described in detail below.

[0074] In some embodiments, the regulation circuit 300 may further include a bus capacitor element C1 and a pre-charge control device Y4, the bus capacitor element C1 and each bridge arm Q1, Q2, and Q3 are connected in parallel, and the pre-charge control device Y4 is connected in parallel with one of the first control switch K1, the second control switch K2, and the third control switch K3.

[0075] For example, as shown in Figure 3, the pre-charge control device Y4 is connected in parallel with the first control switch K1. At this time, the pre-charge control device Y4 is turned on, and the external power supply can pre-charge the bus capacitor element C1. For another example, the pre-charge control device Y4 is connected in parallel with the third control switch K3. At this time, the pre-charge control device Y4 is turned on, and the battery can pre-charge the battery capacitor element C2. For another example, the pre-charge control device can also be connected in parallel with the second control switch. For another example, two pre-charge control devices can be set to be connected in parallel with the first control switch and the second control switch, respectively. The present application is not limited to the above examples.

[0076] In some embodiments, the pre-charge control device Y4 may include a resistor element R1 and a fourth control switch K4 , wherein the fourth control switch may be a controllable power semiconductor device such as a contactor or a MOSFET tube.

[0077] As shown in FIG6 , a regulation method 600 of a regulation circuit for a battery (such as the regulation circuit 300 shown in FIG3 ) in some embodiments of the present application is provided. The regulation method 600 may be executed at a controller of the regulation circuit. The regulation circuit may include a power module and a battery side for connecting to a battery, the power module including a bridge arm group and at least one inductor element, the bridge arm group being connected in parallel with the battery and including a plurality of switching devices, the first end of each inductor element being connected to the bridge arm group. The regulation method may include: step S601, determining whether to regulate the battery; and step S602, in response to determining that the battery is to be regulated, controlling at least a plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module, wherein the first current direction and the second current direction are opposite at the battery.

[0078] In some examples, it can be determined whether to regulate (e.g., heat) the battery based on relevant instructions from the upper controller. Alternatively, the regulation circuit can also determine whether to regulate (e.g., heat) the battery based on parameters such as the battery's temperature, voltage, and state of charge. After determining that the battery needs to be heated, as shown in Figures 7a and 7b, the switching devices in the power module 310 can be controlled to form a current loop H1 or H2 between the power module 310 and the battery 230, that is, by controlling the different states of the switching devices in the power module 310, different current loops can be formed between the power module 310 and the battery 230.

[0079] As shown in Figures 7a and 7b, by controlling the switching devices in the bridge arm group 330, one of a current loop H1 with a first current direction and a current loop H2 with a second current direction can be selectively formed between the battery 230 and the power module 310. Similarly, as shown in Figures 8a and 8d, by controlling the switching devices in the bridge arm group 330, a current loop H1' with a first current direction and a current loop H2' with a second current direction can be formed between the battery 230 and the power module 310. The first and second current directions are opposite at the battery, thereby allowing the battery to be charged and discharged, thereby achieving pulse heating of the battery. It should be noted that whether the current loop with the first current direction or the current loop with the second current direction charges or discharges the battery depends on the direction of the positive and negative poles of the battery. Although Figures 3, 7a and 7b, and 8a to 8d illustrate the positive pole of the battery as the first end of the battery, it should be understood that the negative pole of the battery can also be used as the first end of the battery.

[0080] The above embodiment can utilize the power module to charge and discharge the battery, thereby achieving battery regulation (eg, pulse heating) to meet the requirements for normal operation of the battery.

[0081] In a system with multiple batteries, where each battery is connected to a separate regulation circuit, the above embodiment can form an independent current loop between the power module and the battery, allowing independent heating of the battery. This allows independent heating control of multiple batteries and simultaneous heating of multiple batteries to improve heating efficiency.

[0082] According to some embodiments of the present application, the bridge arm group includes at least one bridge arm, each bridge arm includes at least two corresponding switching devices among a plurality of switching devices. The first end of each inductor element is connected between the two switching devices of a corresponding one of the at least one bridge arm. In response to determining to adjust the regulation circuit, at least controlling the plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switching device of each bridge arm located on one side of the corresponding inductor element to turn on and the switching device of the bridge arm located on the other side of the corresponding inductor element to turn off, so as to form a current loop with the first current direction or a current loop with the second current direction between the battery and the power module.

[0083] That is, for each bridge arm, the switching device on one side of the corresponding inductor element (e.g., one of the upper bridge arm or the lower bridge arm of the bridge arm) can be controlled to be turned on, and the switching device on the other side of the corresponding inductor element (e.g., the other of the upper bridge arm or the lower bridge arm of the bridge arm) can be turned off. For example, as shown in FIG7 a , the switching devices V1 and V2 of the upper bridge arm of bridge arm Q1 are controlled to be turned on, and the switching devices V3 and V4 of the lower bridge arm are controlled to be turned off, while the switching devices V5, V6, V9, and V10 of the upper bridge arms of bridge arms Q2 and Q3 are turned off, and the switching devices V7, V8, V11, and V12 of the lower bridge arms are controlled to be turned on.

[0084] In this way, only the upper arm or the lower arm of each bridge arm can be turned on to ensure that the formed current loop passes through the inductor element in the power module, thereby utilizing the inductor element in the power module to charge and discharge the battery to achieve battery regulation (for example, pulse heating).

[0085] According to some embodiments of the present application, at least one bridge arm includes a plurality of bridge arms connected in parallel, and at least one inductor element includes a plurality of inductors, the second ends of each inductor element being connected to each other. Controlling the switching device of each bridge arm located on one side of the corresponding inductor element to be turned on and the switching device of the bridge arm located on the other side of the corresponding inductor element to be turned off, so as to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switching devices of a portion of the bridge arms located between the corresponding inductor element and the first end of the battery side to be turned on and the switching devices of a portion of the bridge arms located between the corresponding inductor element and the second end of the battery side to be turned off, and controlling the switching devices of another portion of the bridge arms located between the corresponding inductor element and the second end of the battery side to be turned on and the switching devices of another portion of the bridge arms located between the corresponding inductor element and the first end of the battery side to be turned off, so as to form a current loop with the first current direction; and controlling the switching devices that are turned on among the plurality of switching devices to be turned off and the switching devices that are turned off among the plurality of switching devices to be turned on, so as to form a current loop with the second current direction.

[0086] That is, for a bridge arm group having multiple bridge arms, a portion of the bridge arms can be selected to control the switching devices (i.e., upper bridge arms) located between the corresponding inductor element and the first end of the battery side to be turned on and the switching devices (i.e., lower bridge arms) located between the corresponding inductor element and the second end of the battery side to be turned off, and another portion of the bridge arms can be selected to control the switching devices (i.e., lower bridge arms) located between the corresponding inductor element and the second end of the battery side to be turned on and the switching devices (i.e., upper bridge arms) located between the corresponding inductor element and the first end of the battery side to be turned off. For example, as shown in FIG7 a , the switching devices V1 and V2 of the upper bridge arm of bridge arm Q1 are controlled to be turned on, and the switching devices V3 and V4 of the lower bridge arm are controlled to be turned off, while the switching devices V5, V6, V9, and V10 of the upper bridge arms of bridge arms Q2 and Q3 are controlled to be turned off, and the switching devices V7, V8, V11, and V12 of the lower bridge arms are controlled to be turned on. Thus, a current loop H1 with a first current direction can be formed between the inductors L1, L2, and L3 of the power module 310 and the battery 230. Then, as shown in FIG7 b , the previously turned-on switching devices are turned off. Specifically, the switching devices V1 and V2 of the upper arm of the bridge arm Q1 are turned off, while the switching devices V3 and V4 of the lower arm are turned on. The switching devices V5, V6, V9, and V10 of the upper arms of the bridge arms Q2 and Q3 are turned on, while the switching devices V7, V8, V11, and V12 of the lower arms are turned off. At this point, due to the hysteresis effect of the inductors L1, L2, and L3 with respect to the change in current direction, the current in the inductors L1, L2, and L3 can maintain its current direction and continue to flow, thereby forming a current with a second current direction in the new current loop H2, thereby changing the current direction at the battery. Alternatively, in FIG7 a , the upper bridge arms of bridge arms Q1 and Q2 may be controlled to be turned on and the lower bridge arms to be turned off, while the upper bridge arm of bridge arm Q3 may be controlled to be turned off and the lower bridge arm to be turned on. The present application is not limited to the above example. It should be noted that the above steps should be performed in sequence.

[0087] The above embodiments make full use of the hysteresis effect of the inductor element on current changes to achieve rapid charging and discharging of the battery, while avoiding the inductor element hindering current commutation, thereby increasing the frequency of battery regulation (e.g., pulse heating) and thus improving the efficiency of battery regulation (e.g., heating).

[0088] According to some embodiments of the present application, the regulation circuit further includes a battery capacitor element, wherein the first end of the battery capacitor element is connected to the second end of each inductor element, and the second end of the battery capacitor element is connected to the second end of the battery side. Controlling the switching device of each bridge arm located on one side of the corresponding inductor element to turn on and the switching device of the bridge arm located on the other side of the corresponding inductor element to turn off, so as to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling the switching device of each bridge arm located between the corresponding inductor element and the first end of the battery side to turn on, and controlling the switching device of each bridge arm located between the corresponding inductor element and the second end of the battery side to turn off, so as to form a current loop with a first current direction; and at least controlling the switching device of each bridge arm located between the corresponding inductor element and the second end of the battery side to turn off, so as to form a current loop with a second current direction.

[0089] That is, the switch device (i.e., the upper bridge arm) located between the corresponding inductor element and the first end of the battery side of each bridge arm can be controlled to be turned on, while the switch device (i.e., the lower bridge arm) located between the corresponding inductor element and the second end of the battery side can be turned off. As shown in Figure 8a, for bridge arm Q1, the switch devices V1 and V2 located between the corresponding inductor element L1 and the first end of the battery side S2 of the bridge arm Q1 are controlled to be turned on, and the switch devices V3 and V4 located between the corresponding inductor element L1 and the second end of the battery side S2 of the bridge arm Q1 are turned off. Similarly, for bridge arms Q2 and Q3, the switch devices V5, V6, V9, and V10 are controlled to be turned on, while the switch devices V7, V8, V11, and V12 are turned off. In this way, a current loop H1' with a first current direction can be formed between the inductor elements L1, L2, and L3, the battery capacitor element C2, and the battery 230. Then, as shown in FIG8 d , at least the switching devices V3, V4, V7, V8, V11, and V12 of the lower bridge arm of each bridge arm Q1, Q2, and Q3 are controlled to be turned off, so as to form a current loop H2′ with a second current direction between the inductor elements L1, L2, and L3, the battery capacitor element C2, and the battery 230. In the case where the switching device is a power semiconductor device (i.e., including a diode), if the direction of the current is the same as the conduction direction of the diode, then even if the switching device is in the off state, the current can flow through the switching device through the diode. Therefore, in the above steps, the switching devices V1, V2, V5, V6, V9, and V10 of the upper bridge arm of each bridge arm Q1, Q2, and Q3 can be controlled to be turned on or off. Because even if the switching devices V1, V2, V5, V6, V9, and V10 are turned off, the current can flow through the diodes D1, D2, D5, D6, D9, and D10 of these switching devices. It should be noted that the above steps should be performed in sequence.

[0090] The above embodiments can realize a current loop through the inductor element and the capacitor element of the battery, so that the battery can be charged and discharged by utilizing the resonance effect of the inductor element and the capacitor element, thereby improving the efficiency of battery conditioning (for example, heating).

[0091] According to some embodiments of the present application, the plurality of switching devices are power semiconductor devices. Controlling at least the switching device of each bridge arm between the corresponding inductor element and the second end of the battery side to turn off to form a current loop with a second current direction includes: controlling all switching devices of each bridge arm to turn off to form a current loop with a third current direction between the battery capacitor element and the bridge arm group; controlling the switching device of each bridge arm between the corresponding inductor element and the second end of the battery side to turn on to form a current loop with a fourth current direction between the battery capacitor element and the bridge arm group, wherein the third current direction and the fourth current direction are opposite at each inductor element; and controlling the switching device of each bridge arm between the corresponding inductor element and the second end of the battery side to turn off to form a current loop with the second current direction.

[0092] After a period of time has passed since the current loop H1' with the first current direction was formed, the voltage of the battery capacitor C2 in the power module and the voltage of the battery 230 approach each other due to the charging or discharging of the battery. This affects the resonance between the battery capacitor C2 and the inductor elements L1, L2, and L3, thereby affecting the charging and discharging of the battery 230. Therefore, it is necessary to reduce the voltage of the battery capacitor C2. As shown in Figure 8b, by turning off all the switching devices in the bridge arm group 330, the energy of the inductor elements L1, L2, and L3 is retained through the diodes D3, D4, D7, D8, D11, and D12 in the switching devices of the lower bridge arm of the bridge arms Q1, Q2, and Q3 for freewheeling, that is, consuming the energy in the inductor element. At this point, a current loop H3' with a third current direction is formed between the inductor elements L1, L2, and L3 and the battery capacitor element C2. Then, as shown in Figure 8c, the switching devices V3, V4, V7, V8, V11, and V12 of the switching devices (i.e., the lower bridge arm) of each bridge arm Q1, Q2, and Q3 located between the corresponding inductor element and the second end of the battery side are controlled to be turned on, and the switching devices (i.e., the upper bridge arm) located between the corresponding inductor element and the first end of the battery side are kept turned off. At this time, a current loop H4' with a fourth current direction is formed between the inductor elements L1, L2, and L3 and the battery capacitor element C2, so that the battery capacitor element C2 charges the inductor elements L1, L2, and L3, thereby reducing the voltage of the battery capacitor element C2. In the current loop H4', the current at the inductor elements L1, L2, and L3 is reversed compared to the current loop H1'. Thereafter, when forming the current loop H2' with the second current direction, it is convenient to utilize the fourth current direction at the inductor element to quickly form the current loop H2' with the second current direction, thereby avoiding the influence of the hysteresis effect of the inductor element on the current conversion.

[0093] On the one hand, this can restore the resonant effect between the inductor element and the battery capacitor element, and on the other hand, it can make use of the hysteresis effect of the inductor element on the current change to quickly change the current direction at the battery, thereby increasing the frequency of battery regulation (for example, pulse heating) and thus improving the efficiency of battery regulation (for example, heating).

[0094] According to some embodiments of the present application, the regulation circuit further includes a first control switch and a bus side for connecting to an external power source, wherein the first end of the first control switch is connected to the first end of the bus side, the second end of the first control switch is connected to the first end of the bridge arm group, and the second end of the bus side is connected to the second end of the bridge arm group. In response to determining to regulate the regulation circuit, controlling at least a plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module includes: controlling at least the first control switch to turn off; and controlling the plurality of switching devices of the bridge arm group to form a current loop with a first current direction or a current loop with a second current direction between the battery and the power module.

[0095] That is, as shown in FIG. 7 a and FIG. 8 a , before heating the battery, the first control switch K1 between the bus side S1 and the power module 330 is controlled to be turned off.

[0096] This allows the power module to independently regulate (eg, heat) the battery and prevents an external power supply on the bus side from affecting the heating of the battery.

[0097] According to some embodiments of the present application, the regulation circuit further includes a second control switch and a third control switch, wherein a first end of the second control switch is connected to a second end of the first control switch, a second end of the second control switch is connected to a first end of the battery side, a first end of the third control switch is connected to a second end of each inductor element, and a second end of the third control switch is connected to a second end of the second control switch. Controlling at least the first control switch to turn off includes: controlling the first control switch and the third control switch to turn off and the second control switch to turn on.

[0098] That is, as shown in Figures 7a and 8a, before heating the battery, the first control switch K1 between the bus side S1 and the power module 330 and the third control switch K3 between the inductors L1, L2, and L3 and the battery side S2 are turned off, and the second control switch K2 between the bridge arm group 330 and the battery side S2 is turned on. This facilitates battery heating using the circuit between the bridge arm group 330 and the battery side S2.

[0099] This facilitates the regulation circuit to enter a battery regulation (e.g., heating) mode. Furthermore, if a current loop for heating the battery is implemented through the path where the third control switch is located, the current needs to flow back to the battery through the capacitor on the busbar side after passing through the inductor. This may cause circuit instability. Compared to the third control switch, a current loop for heating the battery is implemented through the path where the second control switch is located, which can bypass the capacitor on the busbar side, thereby increasing the stability of battery regulation.

[0100] According to some embodiments of the present application, determining whether to adjust the battery includes: determining whether an adjustment instruction is received, the adjustment instruction is used to instruct to adjust the battery; and in response to determining that the adjustment instruction is received, determining to adjust the battery.

[0101] In some examples, the adjustment instruction may come from an upper-level controller, such as a local energy management system (LEMS), etc. Alternatively, the adjustment instruction may also come from a battery management system (BMS).

[0102] This allows the battery to be adjusted (eg, heated) as needed, thereby meeting the requirements for normal battery operation.

[0103] According to some embodiments of the present application, the adjustment method 600 may further include: determining whether a stop adjustment instruction is received, the stop adjustment instruction is used to instruct to stop adjusting the battery; and in response to determining that the stop adjustment instruction is received, at least controlling all switching devices among a plurality of switching devices to be turned off to stop adjusting the battery.

[0104] As mentioned above, the adjustment instructions may come from a local energy management system, a battery management system, or the like.

[0105] In this way, battery conditioning (eg, heating) can be stopped as needed, thereby avoiding overheating of the battery or ineffective heating of the battery.

[0106] According to some other embodiments of the present application, the regulation circuit may also independently determine whether to regulate the battery based on battery status information. Specifically, determining whether to regulate the battery may also include: obtaining battery status information, the status information including an initial temperature; determining whether the initial temperature is less than a first preset temperature threshold; and determining to regulate the battery in response to determining that the initial temperature is less than the first preset temperature threshold.

[0107] In some examples, battery status information can be obtained through a BMS or corresponding sensors. This status information may also include the state of charge (SOC) and voltage. The initial temperature refers to the battery temperature at the moment the above-mentioned step of determining whether to heat the battery is performed is performed. The first preset temperature threshold can be set based on experience or theory. This allows the battery to be adjusted as needed to meet normal battery operation requirements.

[0108] According to some embodiments of the present application, the status information also includes the state of charge and voltage. In response to determining that the initial temperature is less than a preset temperature threshold, determining to adjust the battery includes: in response to satisfying a first preset condition, determining to adjust the battery, wherein the first preset condition includes at least one of the state of charge being greater than or equal to a preset charge threshold and the voltage being greater than or equal to a preset voltage threshold. That is, after determining that the initial temperature of the battery is less than the preset temperature threshold, it is also possible to determine whether the state of charge of the battery is less than the preset charge threshold and / or whether the voltage of the battery is less than the preset voltage threshold. In this way, it can be determined whether the battery has sufficient energy to regulate itself. The preset charge threshold and the preset voltage threshold can be set based on experience or theory. In this way, it is possible to adjust the battery voltage when it meets specific conditions, thereby increasing the efficiency of battery regulation.

[0109] According to some embodiments of the present application, in response to satisfying a first preset condition, determining to regulate the battery includes: determining whether a regulation circuit has a fault; and in response to determining that the regulation circuit has no fault, determining to regulate the battery. That is, after determining that the first preset condition has been satisfied, it is further determined whether the regulation circuit has a fault. Determining whether the regulation circuit has a fault may include determining whether various components in the regulation circuit (e.g., a switch device, a battery contactor, a capacitor, an inductor, etc.) have a fault. This allows the battery to be regulated even when the regulation circuit has no fault, thereby improving the safety of battery regulation.

[0110] According to some embodiments of the present application, the adjustment method 600 may further include: obtaining the current temperature of the battery at the current moment; and in response to satisfying a second preset condition, controlling at least all of the multiple switching devices to turn off to stop adjusting the battery, wherein the second preset condition includes at least one of the following: the current temperature is greater than or equal to a second preset temperature threshold, and the difference between the current temperature and the initial temperature is less than a preset temperature rise threshold. The current moment refers to the moment when the above steps are performed. The second preset temperature threshold can be set based on experience or theory to indicate that the battery temperature meets the requirements for normal operation. The preset temperature rise threshold can be set based on experience or theory to indicate that the battery temperature rise is normal. In some other embodiments, the battery's historical temperature, that is, the temperature at any time before the current moment, may also be obtained to be used together with the current temperature to determine whether the battery temperature rise is abnormal. This can avoid excessive heating of the battery or ineffective heating of the battery, thereby increasing the safety of battery heating.

[0111] As shown in Figure 9, some embodiments of the present application provide a control method for a battery. Control method 900 may include: step S901, obtaining battery status information, where the status information includes an initial temperature; step S902, determining whether the initial temperature is less than a first preset temperature threshold; and step S903, in response to determining that the initial temperature is less than the first preset temperature threshold, sending an adjustment instruction to a regulation circuit, where the adjustment instruction is used in the adjustment method 600 of the above embodiment.

[0112] The characteristics of the battery, status information, initial temperature, and first preset temperature threshold are the same as those described in FIG6 , and are not described in detail here. The control method 900 may be executed in a higher-level controller, such as a LEMS.

[0113] The battery can thus be adjusted as needed to meet the requirements for normal battery operation.

[0114] According to some embodiments of the present application, the state information further includes a state of charge and a voltage. Step S903, in response to determining that the initial temperature is less than a first preset temperature threshold, sending an adjustment instruction to the adjustment circuit includes: in response to satisfying a first preset condition, sending an adjustment instruction to the adjustment circuit, wherein the first preset condition includes at least one of the state of charge being greater than or equal to a preset charge threshold and the voltage being greater than or equal to a preset voltage threshold.

[0115] That is, after determining that the initial battery temperature is less than the preset temperature threshold, it is further determined whether the battery's state of charge is less than a preset charge threshold and / or whether the battery's voltage is less than a preset voltage threshold. The characteristics of the above-mentioned preset charge threshold and preset voltage threshold are the same as those of the preset charge threshold and preset voltage threshold described in FIG6 and are not further described here.

[0116] This allows the battery voltage to be adjusted when it meets specific conditions, thereby increasing the efficiency of battery regulation.

[0117] According to some embodiments of the present application, in response to satisfying a first preset condition, sending an adjustment instruction to the adjustment circuit includes: determining whether the adjustment circuit has a fault; and in response to determining that the adjustment circuit does not have a fault, sending an adjustment instruction to the adjustment circuit.

[0118] That is, after determining that the first preset condition is satisfied, it may be further determined whether the regulation circuit has a fault. Determining whether the regulation circuit has a fault may include determining whether various components (e.g., a switch, a battery contactor, a capacitor, an inductor, etc.) in the regulation circuit have a fault.

[0119] This allows the battery to be regulated without any faults in the regulation circuit, thereby improving the safety of battery regulation.

[0120] According to some embodiments of the present application, the control method 900 may further include: determining whether the battery temperature rise status information is received, the temperature rise status information including temperature rise abnormality information or temperature rise completion information; and in response to receiving the temperature rise status information, sending a stop adjustment instruction to the adjustment circuit, the stop adjustment instruction is used for the adjustment method 600 of the above embodiment.

[0121] Heating status information can come from, for example, the battery management system. Abnormal heating information indicates abnormal battery heating during the heating process, for example, if the difference between the current battery temperature and the initial temperature (or historical temperature) is less than a preset heating threshold. Complete heating information indicates battery conditioning is complete, for example, if the current battery temperature is greater than or equal to a second preset temperature threshold.

[0122] This makes it easy to monitor the battery status in real time and avoid overheating or ineffective heating of the battery.

[0123] In some other embodiments, the upper-level controller may also independently determine whether to send a stop regulation instruction based on the battery status information. Specifically, control method 900 may also include: obtaining the current temperature of the battery at the current moment and the historical temperature at historical moments; determining whether the battery temperature is abnormally rising based on the current temperature and the historical temperature; and, in response to determining that the battery temperature is abnormally rising, sending a stop regulation instruction to the regulation circuit. The characteristics of the current moment, current temperature, historical moments, and historical temperature described above are the same as those of the current moment, current temperature, historical moments, and historical temperature in Figure 6 and will not be further described here.

[0124] In some other embodiments, the control method 900 may further include: obtaining a current temperature of the battery at a current moment; determining whether the current temperature is greater than or equal to a second preset temperature threshold; and, in response to determining that the current temperature is greater than or equal to the second preset temperature threshold, sending a stop regulation instruction to the regulation circuit. The characteristics of the second preset temperature threshold are the same as those of the second preset temperature threshold in FIG6 and are not further described here.

[0125] As shown in Figure 10, some embodiments of the present application provide a battery monitoring method 1011. Monitoring method 1011 includes: step S1001, collecting current status information of the battery at the current moment, where the current status information includes the current temperature; and step S1002, determining whether to send temperature increase status information to an upper-level controller based at least on the current temperature, where the temperature increase status information is used to execute control method 900 of the above embodiment.

[0126] The characteristics of the battery, current time, current status information, current temperature, and heating status information are the same as those described in FIG9 , and are not described in detail here. The monitoring method 1011 may be executed in a battery management system (BMS).

[0127] This makes it easy to monitor the battery status in real time and avoid overheating or ineffective heating of the battery.

[0128] According to some embodiments of the present application, step S1002, determining whether to send heating status information to the upper-level controller based at least on the current temperature, includes: determining whether the current temperature is greater than or equal to a second preset temperature threshold; and in response to determining that the current temperature is greater than or equal to the second preset temperature threshold, forming heating completion information as heating status information and sending the heating status information to the upper-level controller.

[0129] The characteristics of the second preset temperature threshold are the same as those of the second preset temperature threshold described in Figure 6 and are not described in detail here. In some examples, whether the current temperature is greater than or equal to the second preset temperature threshold can be determined in real time.

[0130] This makes it easier to monitor the battery status in real time and avoid overheating of the battery.

[0131] According to some embodiments of the present application, step S1002, determining whether to send temperature rise status information to an upper-level controller based at least on the current temperature, includes: obtaining the historical temperature of the battery at historical moments; determining whether the battery has abnormal temperature rise based on the current temperature and the historical temperature; and in response to determining that the battery has abnormal temperature rise, generating abnormal temperature rise information as temperature rise status information and sending the temperature rise status information to the upper-level controller.

[0132] The characteristics of the above historical moments and historical temperatures are the same as those described in FIG6 and are not further described here. In some examples, whether the battery temperature is abnormally rising can be determined in real time during the battery heating process. In some examples, the step of determining whether the current temperature is greater than or equal to the second preset temperature threshold can be performed after determining that the battery temperature is not abnormally rising.

[0133] This makes it easier to monitor the battery status in real time and avoid ineffective heating of the battery.
