[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of the present specification. Instead, they are merely examples of devices and methods consistent with some aspects of one or more embodiments of the present specification as detailed in the appended claims.

[0035] It should be noted that in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include but is not limited to more or fewer steps than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may be combined into a single step for description in other embodiments.

[0036] As the market share of electric vehicles increases day by day, the safety requirements for electric vehicles are also getting higher and higher. In particular, the safety of batteries has always been one of the core issues that electric vehicle manufacturers are concerned about. Among them, one of the battery safety issues includes the problem of whether the battery assembly has been properly assembled.

[0037] In order to solve the technical problem that it is difficult to find battery assembly problems when manually visually inspecting the battery assembly area, the embodiment of the present application provides a vehicle battery assembly position monitoring device, which is applied to a vehicle. The vehicle includes a circuit to be detected that is attached to the battery assembly area of ​​the vehicle body; wherein the circuit to be detected includes a signal source, a switch sensor and a controller, and the components are described as follows:

[0038] The signal source is used to provide a signal; the switch sensor is installed in matching with the vehicle body lock body, and the switch sensor is connected to the signal source; the switch sensor can move relative to the battery, contact or separate from the battery, drive the switch sensor to be in a closed state or an open state, so that the circuit to be detected is turned on or off; the controller includes a detection end; the detection end is respectively connected to the signal source and the switch sensor; the controller sends a signal from the signal source detected by the detection end; the signal sent is used to indicate that the switch sensor is in a closed state, and the battery is assembled in place.

[0039] In the embodiment of the present application, a separate circuit to be detected is used to detect that the battery is assembled in place. There is no need for manual inspection based on experience to visually inspect the battery assembly area, and there is no need for manual inspection of battery assembly problems during subsequent use of the car. In this way, the circuit structure is simple and convenient for battery assembly detection. Furthermore, the detection end of the controller can detect whether there is a problem with the battery assembly one step ahead of time when the battery is assembled and before the car is driven, further improving the safety of subsequent battery use and ensuring driving safety.

[0040] Figure 1 Shown is a schematic diagram of a vehicle battery assembly position monitoring device according to an embodiment of the present application.

[0041] like Figure 1 As shown, the automobile battery assembly position monitoring device of the embodiment of the present application is applied to an automobile. The automobile may include but is not limited to a circuit to be detected 10 that is attached to the battery assembly area of ​​the automobile body. The circuit to be detected 10 may include but is not limited to a switch sensor 12 that matches the body lock body in the battery assembly area, a signal source 11 for providing a signal to the circuit to be detected 10, and a controller 13 connected to the switch sensor 12 and the signal source 11 respectively. The signal source 11 sends a signal to the controller 13.

[0042] The battery assembly area is used to accommodate and fix the battery and matches the shape of the battery.

[0043] The circuit to be detected 10 is a complete circuit that needs to be used to detect whether the battery is properly assembled in the battery assembly area. The circuit to be detected 10 is fitted to the position of the body lock body in the battery assembly area of ​​the automobile body and is used in conjunction with the body lock body. In this way, the battery can be locked by the body lock body to prevent the battery from moving, thereby providing safety protection for the battery.

[0044] The switch sensor 12 is matched and installed with the vehicle body lock body, and the switch sensor 12 is connected to the signal source 11; the switch sensor 12 can move relative to the battery, contact or separate from the battery, and drive the switch sensor to be in a closed state or an open state. Specifically, the switch sensor can move relative to the battery, contact the battery, and the switch sensor is in a closed state; or the switch sensor can move relative to the battery, separate from the battery, and the switch sensor is in an open state; when the switch sensor is in a closed state, the circuit 10 to be detected is connected; when the switch sensor is in a disconnected state, the circuit 10 to be detected is disconnected.

[0045] In this way, the switch sensor 12 contacts the battery (at the position where the battery is attached to the body lock body), the detection circuit 10 is connected, and the signal from the signal source 11 can be transmitted to the controller 13. The switch sensor 12 is separated from the battery (at the position where the battery is away from the body lock body), at this time, when the detection circuit 10 is disconnected, the signal from the signal source 11 cannot be transmitted to the controller 13.

[0046] The controller 13 includes a detection terminal (not shown in the figure); the detection terminal is connected to the signal source 11 and the switch sensor 12 respectively; the controller 13 detects the signal sent by the signal source 11 of the circuit to be detected 10 through the detection terminal, and the signal sent is used to indicate that the switch sensor 12 is in a closed state, the circuit to be detected 10 is connected, and the battery is installed in place. The above-mentioned signal not sent is used to indicate that the state of the switch sensor 12 is in an open state.

[0047] Among them, the above-mentioned controller 13 can be a body controller 13, or a power domain controller 13. The power domain controller 13 (Powertrain Management System, PMS) is the core controller 13 of the power-related devices of the whole vehicle, which is equivalent to the brain of the entire three-electric system, and plays an important role in various signal reception, processing and signal transmission. Signal transmission is mainly through hard wire, LIN (Local Interconnect Network, local area interconnect network), CAN (Controller Area Network, controller 13 local area network), Ethernet, and the types of signals can mainly include but are not limited to high and low levels, PWM waves, network messages, etc. The body controller 13 (Body Control Module, BCM) is a module in the automotive electronic system, which is mainly responsible for managing and controlling functions and systems related to the body. The body controller 13 can be responsible for communicating with other components in the circuit 10 to be detected except the body controller 13, and monitoring and controlling whether the battery is assembled in place.

[0048] It should be noted that the signal emitted above refers to the signal output by the signal source 11, or the signal fluctuating within the allowed fluctuation range of the signal output by the signal source 11. Among them, the allowed range is set according to the user's demand range, considering that the signal output by the signal source 11 is related to the noise or loss of the signal transmission. The fluctuating signal is closest to the signal output by the signal source 11. In this way, the emitted signal has some fluctuations or offsets, which increases the applicable scope of the emitted signal. For example, the allowed range is equal to 1V (volt). The signal output by the signal source 11 is a voltage value of 12V, a voltage value of 11.9V, or a voltage value of 12.1V, which are all regarded as the emitted signal. In this way, by further judging the received signal more finely, the accuracy of the received signal can be improved. At the same time, the emitted signal may include but is not limited to the signal output by the signal source 11 and the signal regarded as the output of the signal source 11, which can improve the application scope of signal reception.

[0049] The battery of the above-mentioned car may include but is not limited to a starting battery or a high-voltage battery. The above-mentioned starting battery may be a low-voltage, high-current battery that provides a large amount of current in a short period of time to start the engine. Once the engine starts, the generator of the car starts working, charging the battery and providing power to various systems of the car. The above-mentioned high-voltage battery may be a power battery pack of a hybrid car or an electric car. These battery packs are used to drive the electric motor of the electric car. Any battery that may need to be assembled in the battery assembly area of ​​the car body falls within the scope of protection of the embodiments of the present application and will not be given one by one here.

[0050] Combination Figure 1 As shown, when the car is powered on, the switch sensor 12 can be powered by the car's power supply. Of course, the switch sensor 12 can also be powered by a power supply external to the car.

[0051] It should be noted that the switch sensor 12 can detect whether the battery is properly assembled by directly physically contacting the battery, so as to complete the monitoring of whether the battery is properly assembled.

[0052] When the battery is installed in the battery installation area, the switch sensor 12 is closed. When the car is powered on, it is detected whether the circuit to be detected 10 is conductive and whether the detection end of the controller 13 receives the signal from the signal source 11, which indicates whether the battery is installed in place. Please refer to the following for detailed description.

[0053] In addition, the number of the switch sensors 12 can be adjusted adaptively, and can be two, three, four or more. Figure 2 A, B, C, and D shown represent four switch sensors 12 installed around the battery. Figure 2The diagram shows the relative position of the switch sensor 12 and the battery, not the actual assembly position. In actual applications, the number and position of the switch sensors 12 can be adjusted as needed. For example, only the switch sensor 12A and the switch sensor 12D are configured. For another example, only the switch sensor 12B and the switch sensor 12C are configured, and the line and strategy of the detection circuit 10 also need to be adjusted accordingly.

[0054] Combination Figure 1 As shown, the signal source 11 in this article can be implemented by at least three exemplary signal sources 11 as follows.

[0055] In the first example, the signal source 11 of the circuit 10 to be detected includes at least any one of the following signal sources 11 connected to the car. For example, the signal source 11 can be the wake-up power supply of the car. The controller 13 detects the electrical signal sent by the wake-up power supply of the car through the detection end, and then the battery is assembled in place. In this way, the wake-up power supply of the car itself can be used without changing the structure of the car itself, thereby facilitating the layout and installation.

[0056] The above electrical signal may include but is not limited to a voltage signal or a current signal. For example, the wake-up power supply of the car is KL15, that is, the ON gear power. In this way, KL15 power is used as the signal source 11, and the judgment basis is the output voltage of KL15 and the voltage received by PMS.

[0057] like Figure 2 The circuit diagram shown is the most important part to realize the detection function. A, B, C, and D correspond to Figure 1 The switch sensor 12 and the power domain controller 13PMS.

[0058] When the vehicle is powered on, the power supply output voltage is awakened, for example, the voltage value is 12V, of course, it can also fluctuate around 12V. When the car battery is replaced and powered on, the PMS will detect the voltage values ​​at the interfaces connecting the A and B lines and the C and D lines respectively. When both lines can detect the voltage output by KL15, it means that the battery assembly position is correct. When the voltage output by KL15 is not detected on one or both lines, it means that there is a problem with the battery assembly, and the PMS will send this problem to the driver through the instrument.

[0059] For another example, the signal source 11 may be a component that generates pulse width modulation (PWM). The controller 13 detects a signal sent by the PWM component of the car through the detection terminal, indicating that the battery is installed in place.

[0060] The components of the pulse width modulation PWM signal can be implemented by automobile components or by components external to the automobile. Exemplarily, the components of the pulse width modulation PWM signal can include but are not limited to an electronic control unit (Electronic Control Unit, ECU). The generation of the PWM signal can be achieved by the circuit inside the ECU. Of course, the components that generate the pulse width modulation PWM signal can include but are not limited to the power domain controller 13PMS.

[0061] When the execution subject of this article is the above-mentioned power domain controller 13PMS, the signal it sends itself can also serve as the signal source 11. The power domain controller 13PMS receives the signal and can realize self-inspection. The signal sent by the power domain controller 13PMS itself can include but is not limited to one or more of electrical signals and PWM wave signals, which needs to be designed according to the number of interface resources of the PMS itself.

[0062] In the second example, the signal source 11 of the circuit 10 to be detected includes the following signal source 11 independent of the car. For example, the signal source 11 can be a pressure sensor, which is connected to the switch sensor 12 and the controller 13 respectively; the pressure sensor is in contact with the battery to collect the pressure signal of the battery; the pressure sensor is independently powered; the controller 13 detects the pressure signal emitted by the pressure sensor through the detection end, and the battery is installed in place. In this way, other signal sources 11 outside the vehicle can be used to cooperate to complete the detection of battery installation in place, which is scalable and will not be limited to the signal provided by the car.

[0063] For another example, the signal source 11 may include but is not limited to an oscillator. The controller 13 detects a periodic signal sent by the oscillator through the detection end, and the battery is assembled in place. The periodic signal is, for example, a sine wave, a square wave or a pulse signal.

[0064] In the embodiment of the present application, using at least any one of the wake-up power supply of the automobile, the component generating the pulse width modulation PWM signal, and the oscillator to transmit the signal can improve the diversity of the transmitted signal.

[0065] In the third example, the signal source 11 of the circuit 10 to be detected may include but is not limited to a power domain controller 13PMS. The controller 13 detects a signal sent by the power domain controller 13PMS through the detection end, and the battery is installed in place.

[0066] When the execution subject of this article is the above-mentioned power domain controller 13PMS, the signal it sends itself can also serve as the signal source 11. The power domain controller 13PMS receives the signal and can realize self-inspection. The signal sent by the power domain controller 13PMS itself can include but is not limited to one or more of electrical signals and PWM wave signals, which needs to be designed according to the number of interface resources of the PMS itself.

[0067] Figure 4 Shown Figure 2 The first schematic diagram shows the relative position of the battery contacted by the switch sensor 12 in the vehicle battery installation position monitoring device. Figure 5 Shown Figure 2 The second schematic diagram shows the relative position of the battery contacted by the switch sensor 12 in the vehicle battery installation position monitoring device.

[0068] In such Figure 4 and Figure 5 In the embodiment similar to Figures 2 to 3 The embodiment shown, compared to Figures 2 to 3 In the embodiment of Figure 4 and Figure 5 In the embodiment, the switch sensor 12 is connected to a corresponding position point on the circuit of the circuit to be detected 10; the corresponding position point corresponds to the surface of the battery. The surface of the battery includes the side surface of the battery and / or the bottom surface of the battery. The specific position point corresponds to which specific surface of the battery, which depends on the actual setting.

[0069] The signal emitted by the detection is used to indicate that the switch sensor 12 is in contact with the battery and is closed;

[0070] The above-mentioned signal emitted without detection is used to indicate that the switch sensor 12 is separated from the battery and has been opened.

[0071] The switch sensors 12 may include but are not limited to at least 3 switch sensors 12, which are connected to corresponding positions on the circuit 10 to be detected. All switch sensors 12 are in the same plane and perpendicular to the side wall of the battery assembly area; the plane where all switch sensors 12 are located is flush with the battery installed in the battery assembly area. In this way, it is ensured that the battery installation is flush with the battery assembly area and horizontal.

[0072] All the switch sensors 12 can be separated or contacted with the battery; the switch sensors 12 at all positions are detected to be closed to determine whether the battery is installed in place. Accordingly, the signal sent is used to indicate that the switch sensors 12 at all positions are in contact with the battery and closed.

[0073] The signal emitted when the above-mentioned failure to detect is used to indicate that the switch sensor 12 at least at any position point is separated from the battery and has been opened. For example, if the switch sensors 12 at all positions are not all closed or at least any one is opened, it is determined that the battery is not assembled in place.

[0074] All the switch sensors 12 are located on the same installation plane. Figure 4 The three small circles shown represent the relative positions of the batteries contacted by the three switch sensors 12. The three switch sensors 12 can also be used to monitor whether the batteries are installed flush in the battery assembly area. In this way, the three switch sensors 12 are on the same installation plane, so that the batteries are installed flush in place, which can ensure the stable connection of the batteries in the circuit and facilitate the normal operation of the circuit. This avoids poor contact caused by uneven battery assembly.

[0075] Of course, the number of the switch sensors 12 may also be related to the shape of the battery, the assembly position of the battery assembly area, and the number of the vehicle body lock bodies.

[0076] In a specific example one, the battery is in the shape of a rectangle, and the assembly position of the battery assembly area is the bottom of the vehicle body. The number of vehicle body lock bodies may include but is not limited to at least 4, and the switch sensors 12 include at least 4; all switch sensors 12 are connected at intervals to position points on the line corresponding to the edge of the battery.

[0077] In a specific example 2, the battery is rectangular in shape, the battery assembly area is located at the bottom of the vehicle body, the number of vehicle body lock bodies may include but is not limited to at least 4, and the switch sensors 12 may include but are not limited to at least 4. Specifically, 4 switch sensors 12 are connected to the first position points on the line, and the first position points correspond to the 4 corners of the battery; the remaining switch sensors 12 are connected to the second position points on the line at intervals, and the second position points correspond to the sides of the battery.

[0078] Thus, in the above two examples, after the battery is installed in place, the four sensors located around the battery are closed at the same time, and are always in a state of passage during normal driving, and this state is transmitted to the driver in real time through the power domain controller 13 and the instrument.

[0079] In addition, the connection mode of the contact sensor circuit can also be various, for example, four switch sensors 12 are connected in parallel or in series, and correspond to different numbers of interfaces to connect to the power domain controller 13 .

[0080] In this embodiment, the realization of this function does not require too much additional cost. In terms of hardware, only four switch sensors 12 and corresponding circuits need to be added. In terms of strategy, too complicated programs are not required to realize the function of detecting whether the battery is installed in place.

[0081] Combination Figure 2 As shown, in some embodiments, the circuit to be detected 10 may include one circuit. Of course, in other embodiments, the circuit to be detected 10 may include but is not limited to a first circuit and a second circuit.

[0082] The circuit to be detected 10 includes a first circuit and a second circuit; the first circuit and the second circuit are installed in the battery assembly area and are respectively matched with the vehicle body lock body; the first circuit and the second circuit both include the controller 13;

[0083] The controller 13 includes a first receiving end connected to the signal source 11 and located in the first loop, and a first detection end connected to the first receiving end; the controller 13 detects a first signal emitted by the signal source 11 of the loop to be detected 10 through the first detection end, and the battery is assembled in place at the battery assembly area corresponding to the first loop;

[0084] The controller 13 also includes a second receiving end connected to the signal source 11 and a second detection end connected to the second receiving end, which is located in the second loop; when the controller 13 detects the second signal emitted by the signal source 11 of the loop 10 to be detected through the second detection end, the battery is assembled in place at the battery assembly area corresponding to the second loop.

[0085] The "first" in the "first loop" and the "second" in the "second loop" are used to distinguish between two loops 10 to be detected, and do not limit the number and order. The first loop can represent multiple loops 10 to be detected, or it can represent one loop 10 to be detected. Similarly, the second loop can represent multiple loops 10 to be detected, or it can represent one loop 10 to be detected. The first signal and the second signal are the same, and will not be repeated here.

[0086] The battery assembly area corresponding to the first loop and the battery assembly area corresponding to the second loop are partial areas of the battery assembly area, respectively. In this way, it can be verified whether each partial area is assembled in place.

[0087] In the above optional embodiment, multiple detection circuits and the controller 13 cooperate to implement multi-circuit detection to detect the assembly status of the battery. For the situation where one circuit is not in place and all circuits are not in place at the same time, a classification strategy is implemented to make different response measures later.

[0088] Combination Figure 2 As shown, in some optional embodiments, the device may also include but is not limited to: a prompt module, which is used to generate prompt information that the battery is not assembled in place; a communication module, which is used to send the prompt information to the interactive terminal; the prompt information is used to prompt that the circuit to be detected 10 corresponding to the signal is not received. The prompt information is also used to prompt the circuit to be detected 10 corresponding to the signal is received. In this way, the communication module displays the prompt information, and locates the specific position of the battery that is not assembled in place in time, so that the user can handle it as soon as possible.

[0089] The prompt module may include but is not limited to at least any one of the following: a sound alarm, a light alarm and a vibration alarm.

[0090] The communication module is used to realize the communication between the interactive terminal and the circuit to be detected 10. The communication module may include but is not limited to at least any one of the following: a Zigbee module, a wifi module and a Bluetooth module.

[0091] Each of the above-mentioned circuits to be detected 10 is installed in the battery assembly area and matches the vehicle body lock body. One circuit to be detected 10 can be fixed corresponding to the vehicle body lock body. If any circuit to be detected 10 does not receive a signal and / or is not an allowable signal, the information corresponding to the circuit to be detected 10 can be generated as prompt information. In this way, the specific lock body that is not assembled in place can be identified to determine whether it is assembled in place.
