[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0032] Figure 1 The flowchart of the charging management method provided by one embodiment of the present application is schematically shown.

[0033] like Figure 1 As shown, this application provides a charging management method, which is as follows:

[0034] S110 : In each detection cycle, obtain the output current of the power supply.

[0035] Specifically, the power supply is used to charge the battery module. The power supply can be a photovoltaic input power source or an alternating current (AC) input power source that charges the battery through an inverter (INV). The output current of the power supply is input into the battery module. The detection period is the time interval for detecting the output current of the power supply. For example, if the detection period of the output current of the power supply is 3 seconds, the output current of the power supply is detected every 3 seconds.

[0036] In one embodiment of the present application, before obtaining the output current of the power supply in each detection cycle, it also includes: obtaining the rated charging current of the battery module in response to the charging operation; and determining the initial value of the requested current according to the rated charging current of the battery module.

[0037] Specifically, the steps for determining the charging operation include: (1) the battery module is connected to the power supply before it is turned on, and the charging operation is not considered to be triggered when the battery module is not turned on, and the charging operation is considered to be triggered when the battery module is turned on; (2) the battery module is connected to the power supply, and the charging operation needs to be started by a computer program, that is, the charging operation is not considered to be triggered when the computer program is not triggered, and the charging operation is considered to be triggered when the computer program is triggered; (3) the charging operation is considered to be triggered when the power supply is connected to the battery module.

[0038] The rated charging current refers to the allowable current when the battery module is continuously charged under rated environmental conditions (ambient temperature, sunshine, altitude, installation conditions, etc.).

[0039] The requested current is a charging current requested from the power supply according to the rated charging current of the battery module.

[0040] If the requested current is too large, the output current of the power supply will be greater than the rated charging current of the battery module, which will easily trigger the overcurrent protection of the battery module and make the charging process unstable. Therefore, after responding to the charging operation, the rated charging current of the battery module is obtained, and then the initial value of the requested current is determined according to the rated charging current of the battery module. The output current of the power supply changes with the change of the requested current.

[0041] S120. If the output current is less than the required current of the battery module, calculate the difference between the required current and the output current; update the requested current according to the difference, and generate a request instruction according to the updated requested current; and send the request instruction to the power supply.

[0042] Specifically, the demand current is the current required for charging the battery module. The request instruction is a command sent to the power supply requesting an output current. The output current of the power supply is compared with the demand current of the battery module. If the output current is less than the preset demand current, the request current is updated based on the difference between the two. The request instruction is generated based on the updated request current. This allows the request current to be dynamically adjusted, and thus the output current of the power supply, to gradually adjust the output current to the demand current.

[0043] In one embodiment of the present application, updating the requested current according to the difference includes: determining an adjustment value according to the difference, where the adjustment value is positively correlated with the difference; and adding the adjustment value to the requested current to obtain an updated requested current.

[0044] In one embodiment of the present application, determining the adjustment value according to the difference includes: calculating the product of the difference and a preset adjustment coefficient to obtain the adjustment value.

[0045] Specifically, the adjustment value is determined based on the difference, and the adjustment value is positively correlated with the difference, that is, the larger the difference, the larger the adjustment value; the smaller the difference, the smaller the adjustment value. The preset adjustment coefficient is the relationship coefficient between the predetermined difference and the adjustment value. Let the difference be ΔI a , the preset adjustment coefficient is k, then the adjustment value ΔI:

[0046] ΔI=k·ΔI a

[0047] Then the updated requested current I′ r :

[0048] I′ r =I r +ΔI

[0049] When the demand current I is 12A, the requested current I r is 18A, output current I o When the current is 11A, the difference ΔIa For 1A, if the preset adjustment coefficient k is 3, then ΔI=3·ΔI a , at this time the adjustment value ΔI is 3A, and the updated requested current I′ r It is 21A.

[0050] In one embodiment of the present application, the initial value of the requested current is 0.

[0051] Specifically, when there is no charging operation, the request current is at an initial value, and the initial value is 0. In response to the charging operation, the request current changes from 0, and the output current also changes from 0.

[0052] S130. If the output current is greater than or equal to the demand current, the demand current is changed from the first value to the second value, and after a preset time, the step of obtaining the output current of the power supply in each detection cycle is returned to; the first value is less than the second value.

[0053] Specifically, the preset duration is the duration of time from when the output current reaches the first value to when it stabilizes at the first value, as determined after a large number of tests. If the output current of the power supply is greater than or equal to the first value of the required current of the battery module, the output current of the power supply will continuously fluctuate around the first value of the required current. After the preset duration, when the output current stabilizes at the first value, the required current is changed from the first value to the second value, and then the process returns to S110. For example, the required current I1 at the first value is 12A, and the requested current I r The output current of the power supply is 18A. o When the output current is 12A, the output current I o Equal to the demand current I1 at the first value, after the preset time, the output current I o If the current tends to be stable, the demand current is changed from the first value to the second value, and the demand current I2 at the second value is obtained to be 14 A, and the process returns to S110 again.

[0054] The present application obtains the output current of the power supply and compares it with the demand current of the battery module. If the output current is less than the demand current, the difference between the demand current and the output current is calculated; the requested current is updated based on the difference, and a request instruction is generated based on the updated request current; and the request instruction is sent to the power supply. If the output current is greater than or equal to the demand current, the demand current is changed from a first value to a second value, and after a preset time, the process returns to the step of obtaining the output current of the power supply in each detection cycle. Thus, the power supply outputs current according to the request instruction. The charging management method provided in the embodiment of the present application generates a request instruction based on the difference between the demand current and the output current. By changing the value of the demand current, the output current can be controlled to have only a small adjustment when reaching the second value of the demand current. This can solve the problem of large current amplitude jitter caused by directly increasing the output current of the power supply from zero to the second value of the demand current, avoid the risk of overcurrent to the battery pack and the charging circuit of the battery pack, and thus avoid damage to the battery pack or the charging circuit of the battery pack, thereby improving the circuit safety of the charging process of the electronic device.

[0055] Figure 2 The graph schematically shows the curves of the requested current and the output current changing with time in the prior art.

[0056] In the field of charging technology, when the battery management system (BMS) requests a power supply to charge the battery module, the slopes of the BMS's requested current and the AC's output current (when AC needs to be converted, this is the BMS's requested current and the INV's output current) are inconsistent, and the AC's output response is slower than the BMS's request. When the actual required current is not reached, the BMS can only continue to increase the requested current, so that the requested current is always greater than the output current, thereby increasing the AC's output current. In actual use, after the AC's output current or the INV's output current reaches the requested current, there will be current jitter. This current jitter is because the INV's output angle φ is unstable. According to the INV's output angle value φ, which is determined by the inverse tangent function of the ratio of the input sine, sin, and cosine voltages, when the INV itself is normal, the jitter of its output angle is not only related to the stability of the input sine and cosine voltage values, but also to the settings of the peripheral parameters of the chip used in the INV. That is, the present application aims to solve the problem that when charging with AC output current or INV output current, the battery module is damaged due to current jitter in the output current.

[0057] For example, Figure 2 As shown, the actual demand current I need The requested current is 12A. ris 18A, but the AC output current I o When it is about to stabilize at the actual demand current I need Before, that is Figure 2 After a period of time t1, the output current I o Strong current jitter will occur, such as the output current I o Jump in the range of 10A to 14A. Once the output current I o If the overcurrent point is exceeded, the overcurrent protection of the BMS will be easily triggered, resulting in an unstable charging process of the battery module and even damage to the battery pack or the charging circuit of the battery pack.

[0058] Figure 3 The curves showing the change of the requested current and the output current over time in the charging management method provided by the present application are schematically shown.

[0059] For example, Figure 3 As shown, the actual required current of the battery module I need is 14A. According to the charging management method provided in this application, before t1, the demand current I is 12A and the request current I is r The output current of the power supply I increases gradually from 0 to 18A. o Also gradually increases from 0 to 12A. At t1, the output current I o =Equal to the demand current I, change the demand current I to 14A. Due to the characteristics of the output current of AC or the output current of INV, within ΔT after t1, the output current I o In a state of continuous jump, because the request current I r and the power supply output current I o There is a corresponding relationship between them, so the requested current I r It will also continue to jitter. Output current I o The continuous jump occurs before the actual required current is reached, and the output current will not jump to trigger the overcurrent protection. After ΔT, starting from t2, the output current I o is less than the required current, so the requested current I is updated according to S120 r ′, request current I r The curve rises slowly after t2, and the output current I o The curve also rises slowly and stabilizes after t3 to be equal to the actual demand current I need , after which the requested current I r The curve also tends to be stable and stabilizes at 20A.

[0060] In one embodiment of the present application, after determining that the output current is greater than or equal to the demand current, the method further includes: updating the value of the preset adjustment coefficient from the first coefficient to the second coefficient, where the first coefficient is greater than the second coefficient.

[0061] Specifically, after determining that the output current is greater than or equal to the demand current, the demand current is changed from the first value to the second value, and the first value is less than the second value. In addition, the preset adjustment coefficient is updated from the first coefficient to the second coefficient, and the first coefficient is greater than the second coefficient. For example, Figure 3 As shown, the actual demand current I need is 14A, the demand current I1 at the first value is 12A, the demand current I2 at the second value is 14A, and the request current I before the update is r The output current before the update is 18A. o is 12A, the first coefficient is equal to 3, the second coefficient is equal to 1, then ΔI=ΔI a Therefore, after updating the demand current I2 to 14A, the difference ΔI a is 2A, the adjustment value ΔI is 2A, and the updated requested current I r ' is 20A. In the case of the same difference, according to ΔI=k·ΔI a When the preset adjustment coefficient is the first coefficient, the adjustment value ΔI is 6A, and the updated requested current I r ' is 24A, the output current I o Therefore, after determining that the output current is greater than or equal to the demand current, the preset adjustment coefficient is updated from the first coefficient to the second coefficient, and the requested current I r The curve rises slowly after t2, and the output current I o The curve of the updated request current I′ also rises slowly with it. r Slowly rise, so that the output current I o It changes slowly when approaching the required current, reducing the large jitter of the output current and improving the stability of the power supply output current.
