本申请涉及电源技术领域，特别涉及一种充电方法、充电装置、储能电源和计算机可读存储介质。The present application relates to the field of power supply technology, and in particular to a charging method, a charging device, an energy storage power supply and a computer-readable storage medium.
在相关技术中，移动式储能电源充满电后会有长时间连接充电器的现象，此时移动式储能电源内部的电源存在低功耗消耗电池的电量以及电池满电条件下自放电，均会导致移动式储能电源内电池的荷电状态下降，为了保证移动式储能电源在拔掉充电器后依然满电，电池管理系统会采取掉电后立即启动充电进行补电的策略，这就造成移动式储能电源出现较高频率的浮充现象。高频次浮充会影响移动式储能电源的循环寿命，甚至导致安全风险。In the related art, after the mobile energy storage power supply is fully charged, it will be connected to the charger for a long time. At this time, the power supply inside the mobile energy storage power supply has low power consumption and self-discharge under the condition of full battery, which will cause the state of charge of the battery in the mobile energy storage power supply to decrease. In order to ensure that the mobile energy storage power supply is still fully charged after the charger is unplugged, the battery management system will adopt the strategy of starting charging immediately after power failure to replenish power, which causes the mobile energy storage power supply to have a higher frequency of floating charge. High frequency floating charge will affect the cycle life of the mobile energy storage power supply and even lead to safety risks.

请参图1，本申请实施方式的一种充电方法用于电芯30充电。充电方法包括：Referring to FIG. 1 , a charging method according to an embodiment of the present application is used to charge a battery cell 30. The charging method includes:
步骤001：获取电芯30的当前荷电状态；Step 001: Obtain the current state of charge of the battery cell 30;
步骤002：在电芯30的当前荷电状态小于或等于预设荷电状态的情况下，控制电源对电芯30充电，预设荷电状态由电芯30在预设期间内的浮充次数确定；Step 002: When the current state of charge of the battery cell 30 is less than or equal to a preset state of charge, the power supply is controlled to charge the battery cell 30, and the preset state of charge is determined by the number of floating charges of the battery cell 30 within a preset period;
步骤003：在电芯30的当前荷电状态大于预设荷电状态的情况下，保持电芯30的当前状态。Step 003: When the current state of charge of the battery cell 30 is greater than the preset state of charge, the current state of charge of the battery cell 30 is maintained. state.
上述充电方法中，通过在电芯30的当前荷电状态小于或等于预设荷电状态的情况下，控制电源对电芯30充电，而预设荷电状态为电芯30在预设期间内的最大浮充次数所确定的，从而使得电芯30与电源断开连接后仍可保持100％荷电状态，避免电芯30由于内部功耗掉电而进行高频次浮充，提高电芯30的循环寿命，降低安全风险。In the above-mentioned charging method, the power supply is controlled to charge the battery cell 30 when the current charge state of the battery cell 30 is less than or equal to the preset charge state, and the preset charge state is determined by the maximum number of floating charges of the battery cell 30 within a preset period, so that the battery cell 30 can still maintain a 100% charge state after being disconnected from the power supply, avoiding high-frequency floating charging of the battery cell 30 due to internal power consumption, thereby improving the cycle life of the battery cell 30 and reducing safety risks.
具体地，在一个实施方式中，电芯30连接电源充电至100％荷电状态后，保持与电源连接。系统可通过检测电芯30的实时情况，从而获取电芯30的当前荷电状态。系统可对电芯30设定有定值的预设荷电状态。系统可对电芯30的当前荷电状态与预设的荷电状态进行比较。在一个实施方式中，在电芯30的当前荷电状态小于或等于预设荷电状态的情况下，系统可控制电源对电芯30充电。预设荷电状态小于100％荷电状态。例如，当获取到电芯30的当前荷电状态为89％，预设荷电状态为90％，电芯30的当前荷电状态89％小于预设荷电状态90％，则控制电源对电芯30进行充电。预设荷电状态是由电芯30在预设期间内的浮充次数确定。例如，一个电芯30在一年内连接电源进行浮充的次数，可得出该电芯30设定的预设荷电状态。在一个实施方式中，在电芯30的当前荷电状态大于预设荷电状态的情况下，保持电芯30的当前状态，不对电芯30进行充电。也就是说，通过在电芯30的当前荷电状态小于或等于预设荷电状态的情况下，控制电源对电芯30充电，从而使得电芯30与电源断开连接后仍可保持100％荷电状态，避免电芯30由于内部功耗掉电而进行高频次浮充，提高电芯30的循环寿命，降低安全风险。Specifically, in one embodiment, after the battery cell 30 is connected to the power source and charged to 100% state of charge, it remains connected to the power source. The system can obtain the current state of charge of the battery cell 30 by detecting the real-time situation of the battery cell 30. The system can set a preset state of charge with a fixed value for the battery cell 30. The system can compare the current state of charge of the battery cell 30 with the preset state of charge. In one embodiment, when the current state of charge of the battery cell 30 is less than or equal to the preset state of charge, the system can control the power source to charge the battery cell 30. The preset state of charge is less than 100% state of charge. For example, when the current state of charge of the battery cell 30 is obtained to be 89%, the preset state of charge is 90%, and the current state of charge of the battery cell 30 is 89% less than the preset state of charge 90%, then the power source is controlled to charge the battery cell 30. The preset state of charge is determined by the number of floating charges of the battery cell 30 within a preset period. For example, the number of times a battery cell 30 is connected to the power source for floating charge within a year can be used to obtain the preset state of charge set for the battery cell 30. In one embodiment, when the current state of charge of the battery cell 30 is greater than the preset state of charge, the current state of the battery cell 30 is maintained and the battery cell 30 is not charged. That is, by controlling the power supply to charge the battery cell 30 when the current state of charge of the battery cell 30 is less than or equal to the preset state of charge, the battery cell 30 can still maintain a 100% state of charge after being disconnected from the power supply, thereby avoiding high-frequency floating charging of the battery cell 30 due to power failure due to internal power consumption, thereby increasing the cycle life of the battery cell 30 and reducing safety risks.
需要说明的是，对于不同型号的电芯30，在最严苛的条件下，浮充次数对电芯30的安全性影响的最高承受能力，可表现为电芯30的浮充次数的最大值。在一个实施方式中，电芯30在一般情况下一年内的浮充次数可达到上万次，若将电芯30无论处于何种条件下的浮充次数均控制在远远低于电芯30的浮充次数的最大值，可减少电芯30内部的副反应的发生，降低电池内部产气，防止内压增大，保证电芯30的安全性。It should be noted that, for different types of battery cells 30, under the most stringent conditions, the highest tolerance of the impact of the number of floating charges on the safety of the battery cells 30 can be expressed as the maximum number of floating charges of the battery cells 30. In one embodiment, the number of floating charges of the battery cells 30 in a year under normal circumstances can reach tens of thousands of times. If the number of floating charges of the battery cells 30 is controlled to be far lower than the maximum number of floating charges of the battery cells 30 regardless of the conditions, the occurrence of side reactions inside the battery cells 30 can be reduced, the gas production inside the battery can be reduced, the internal pressure can be prevented from increasing, and the safety of the battery cells 30 can be ensured.
另外，在图2所示的实施方式中，横坐标为电芯30充放电的循环次数，纵坐标为电芯30的容量保持率。L1表示本申请实施方式的充电方法的电芯30，L2表示对比方案的电芯。采取本申请实施方式的充电方法的电芯30的循环寿命比对比方案的电芯的循环寿命明显提升。对比方案为一般情况下的浮充充电方式。循环寿命是电芯30可以经历的循环重复充电和放电的次数。In addition, in the embodiment shown in FIG2 , the horizontal axis is the number of charge and discharge cycles of the battery cell 30, and the vertical axis is the capacity retention rate of the battery cell 30. L1 represents the battery cell 30 of the charging method of the embodiment of the present application, and L2 represents the battery cell of the comparative scheme. The cycle life of the battery cell 30 using the charging method of the embodiment of the present application is significantly improved than the cycle life of the battery cell of the comparative scheme. The comparative scheme is a floating charge method under normal circumstances. The cycle life is the number of repeated charge and discharge cycles that the battery cell 30 can undergo.
在某些实施方式中，预设荷电状态由电芯30在预设期间内的浮充次数确定的步骤包括：In some embodiments, the step of determining the preset state of charge by the number of float charges of the battery cell 30 within a preset period includes:
获取电芯30在预设期间的损耗电量；Obtaining power consumption of the battery cell 30 during a preset period;
基于损耗电量确定电芯30的浮充电量，浮充电量等于损耗电量；Determine the floating charge capacity of the battery cell 30 based on the power consumption, the floating charge capacity being equal to the power consumption;
基于浮充电量及浮充次数，确定预设荷电状态。The preset state of charge is determined based on the float charge amount and the float charge times.
如此，可确定预设荷电状态。In this way, a preset state of charge can be determined.
具体地，在一个实施方式中，系统可通过设备记录等方法获取到电芯30在预设期间的损耗电量。损耗电量可包括电芯30存在低功耗消耗电芯30的电量和电芯30满电条件下会存在自放电释放的电量。根据损耗电量可确定需要的浮充电量，也即浮充电量等于损耗电量。例如，电芯30在预设期间的损耗电量的数值可为20，电芯30的满充电量数值可为100，要使电芯30的电量达到满充电量的数值，则需要把损耗电量通过充电充回，即是需要浮充电量为20。最后根据浮充电量及浮充次数，可确定预设荷电状态。Specifically, in one embodiment, the system can obtain the power loss of the battery cell 30 during a preset period through methods such as device recording. The power loss may include the power of the battery cell 30 that consumes low power and the power released by self-discharge when the battery cell 30 is fully charged. The required floating charge capacity can be determined based on the power loss, that is, the floating charge capacity is equal to the power loss. For example, the value of the power loss of the battery cell 30 during the preset period can be 20, and the value of the full charge capacity of the battery cell 30 can be 100. To make the power of the battery cell 30 reach the value of the full charge capacity, the power loss needs to be charged back, that is, the required floating charge capacity is 20. Finally, based on the floating charge capacity and the number of floating charges, the preset state of charge can be determined.
在某些实施方式中，根据以下公式计算预设荷电状态：
S2＝100％-(m×I)/(n×C0)，In some embodiments, the preset state of charge is calculated according to the following formula:
S2 = 100% - (m × I) / (n × C0),
其中，n表示电芯30在预设期间内的浮充次数，m表示预设期间的时长数，I表示电芯30的功耗电流，S2表示预设荷电状态，C0表示电芯30的标称电量。Wherein, n represents the number of float charges of the battery cell 30 within a preset period, m represents the duration of the preset period, I represents the power consumption current of the battery cell 30 , S2 represents the preset state of charge, and C0 represents the nominal power of the battery cell 30 .
如此，可确定预设荷电状态。In this way, a preset state of charge can be determined.
具体地，在一个实施方式中，可先获取电芯30在预设期间内的浮充次数。例如预设期间为一年，预设期间的时长数可用小时为单位，则m可为365天乘以24小时，电芯30在一年内的浮充次数n可为80，此条件下电芯30的安全性和循环寿命最佳。然后再通过系统获取电芯30的功耗电流I和电芯30的标称电量C0，根据公式S2＝100％-(365×24×I)/(80×C0)计算，由于I和C0为已知量，通过公式推导可计算出未知量S2，从而可确定预设荷电状态。Specifically, in one embodiment, the number of floating charges of the battery cell 30 within a preset period can be obtained first. For example, if the preset period is one year, and the duration of the preset period can be in hours, then m can be 365 days multiplied by 24 hours, and the number of floating charges n of the battery cell 30 within one year can be 80. Under this condition, the safety and cycle life of the battery cell 30 are optimal. Then, the power consumption current I of the battery cell 30 and the nominal power C0 of the battery cell 30 are obtained through the system, and calculated according to the formula S2=100%-(365×24×I)/(80×C0). Since I and C0 are known quantities, the unknown quantity S2 can be calculated by derivation of the formula, so that the preset state of charge can be determined.
需要说明的是，电芯30的功耗电流指的是，电芯30在没有进行任何操作的情况下，电芯30在待机状态下的电流。It should be noted that the power consumption current of the battery cell 30 refers to the current of the battery cell 30 in a standby state when the battery cell 30 is not performing any operation.
请结合图3，在某些实施方式中，预设期间包括一年。电芯30在一年内的浮充次数小于或等于80。3 , in some embodiments, the preset period includes one year, and the number of float charges of the battery cell 30 in one year is less than or equal to 80.
如此，可提高电芯30的循环寿命，保证电芯30的安全性。In this way, the cycle life of the battery cell 30 can be improved and the safety of the battery cell 30 can be ensured.
具体地，在一个实施方式中，将电芯30放置在60℃的高温环境中，在此环境条件下电芯30浮充对电芯30的安全性和循环寿命的影响可到达最大。图3是三元高镍材料的圆柱电芯为测试电芯进行一般浮充测试得到的表格数据。在图3中，测试电芯可设有10个，将测试电芯按以下步骤测试：第1步，将测试电芯放入到60℃的高温环境中静置1小时；第2步，以小电流将测试电芯恒流充电至电压4.2V，4.2V可为测试电芯的上限电压；第3步，以电压4.2V将测试电芯恒压充电至0.05C，0.05C为测试电芯充电时的容量；第4步，以小电流将测试电芯恒流放电至电压4.1V，4.1V可为测试电芯的下限电压；第5步，重复第3步和第4步，循环测试14天或CID(电流切断装置)翻转。最终测试的结果为10个测试电芯中出现了4个测试电芯的CID翻转达到8000次以上，其它6个测试电芯未出现CID翻转，这4个测试电芯分别是第4号测试电芯CID翻转8860次、第6号测试电芯CID翻转8591次、第7号测试电芯CID翻转8730次和第10号测试电芯CID翻转8440次。因此，根据表格数据可得出，测试电芯在8000次以上浮充后，测试电芯的内压增大，从而导致CID翻转，此时测试电芯的电压为零，测试电芯可出现临界安全风险。另外，CID翻转指的是，当电芯失效时(如过热、短路、过充等)，内部将产生很多气体，压力增大时焊接到铝板及泄压片上的焊点脱落，泄压片翻转，导致电芯内部断路，而起到保护作用。Specifically, in one embodiment, the battery cell 30 is placed in a high temperature environment of 60°C, and under this environmental condition, the floating charge of the battery cell 30 can reach the maximum impact on the safety and cycle life of the battery cell 30. Figure 3 is a tabular data obtained by performing a general floating charge test on the cylindrical battery cell of ternary high nickel material as a test battery cell. In Figure 3, there can be 10 test cells, and the test cells are tested according to the following steps: Step 1, place the test cell in a high temperature environment of 60°C and let it stand for 1 hour; Step 2, charge the test cell with a small current to a voltage of 4.2V, and 4.2V can be the upper limit voltage of the test cell; Step 3, charge the test cell with a voltage of 4.2V to 0.05C, and 0.05C is the capacity of the test cell when it is charged; Step 4, discharge the test cell with a small current to a voltage of 4.1V, and 4.1V can be the lower limit voltage of the test cell; Step 5, repeat steps 3 and 4, and perform the cycle test for 14 days or the CID (current cut-off device) is flipped. The final test result showed that the CID flipping of 4 out of 10 test cells reached more than 8,000 times, and the CID flipping of the other 6 test cells did not occur. The four test cells are test cell No. 4 with CID flipping 8860 times, test cell No. 6 with CID flipping 8591 times, test cell No. 7 with CID flipping 8730 times, and test cell No. 10 with CID flipping 8440 times. Therefore, according to the data in the table, it can be concluded that after the test cell is float-charged for more than 8000 times, the internal pressure of the test cell increases, which causes the CID to flip. At this time, the voltage of the test cell is zero, and the test cell may have a critical safety risk. In addition, CID flipping means that when the cell fails (such as overheating, short circuit, overcharging, etc.), a lot of gas will be generated inside. When the pressure increases, the solder joints welded to the aluminum plate and the pressure relief plate will fall off, and the pressure relief plate will flip, causing the internal circuit of the cell to be broken, thus playing a protective role.
需要说明的是，根据测试电芯的测试数据总结得出：电芯30在高温的极端环境下在8000次以上的浮充会出现产气，导致电芯30的内部压力增大，带有CID的电芯30会出现翻转，导致电芯30的电压为零。在一个实施方式中，若将电芯30在一年内的浮充次数控制在80以内，也即是最大浮充次数为临界风险浮充次数的10％，从而可提高电芯30的循环寿命，保证电芯30的安全性。It should be noted that according to the test data of the test battery cell, it is concluded that the battery cell 30 will produce gas after more than 8,000 float charges in an extreme environment of high temperature, causing the internal pressure of the battery cell 30 to increase, and the battery cell 30 with the CID will flip, causing the voltage of the battery cell 30 to be zero. In one embodiment, if the number of float charges of the battery cell 30 in one year is controlled within 80, that is, the maximum number of float charges is 10% of the critical risk float charge number, the cycle life of the battery cell 30 can be improved and the safety of the battery cell 30 can be ensured.
在某些实施方式中，电芯30的当前荷电状态由以下公式计算：
S1＝100％－(I×t)/C0，In some embodiments, the current state of charge of the battery cell 30 is calculated by the following formula:
S1＝100％－(I×t)/C0，
其中，S1表示电芯30的当前荷电状态，I表示电芯30的功耗电流，t表示电芯30从100％荷电状态掉电至计算电芯30的当前荷电状态时之间的时间，C0表示电芯30的标称电量。Among them, S1 represents the current state of charge of the battery cell 30 , I represents the power consumption current of the battery cell 30 , t represents the time from when the battery cell 30 loses power from 100% state of charge to when the current state of charge of the battery cell 30 is calculated, and C0 represents the nominal power of the battery cell 30 .
如此，可确定电芯30的当前荷电状态。In this way, the current state of charge of the battery cell 30 can be determined.
具体地，在一个实施方式中，系统可获取电芯30的功耗电流I和电芯30的标称电量，然后记录电芯30的100％荷电状态的具体时间，再记录电芯30从100％荷电状态掉电至计算电芯30的当前荷电状态的具体时间，从而得到两个时间之间的时长t。例如，记录电芯30的100％荷电状态的具体时间为12：00，再记录电芯30从100％荷电状态掉电至计算电芯30的当前荷电状态的具体时间为15:00，那么这两个时间之间的时长t＝3小时。电芯30的标称电量可为电芯30的理论值。将获取到的数据，系统通过设定的运算公式S1＝100％－(I×t)/C0，I、t和C0皆为已知量，最终可计算出电芯30的当前荷电状态。另外，计算公式S1＝100％－(I×t)/C0可通过安时积分法处理得到。Specifically, in one embodiment, the system can obtain the power consumption current I of the battery cell 30 and the nominal power of the battery cell 30, and then record the specific time of 100% state of charge of the battery cell 30, and then record the specific time when the battery cell 30 is powered off from 100% state of charge to calculate the current state of charge of the battery cell 30, so as to obtain the duration t between the two times. For example, the specific time of 100% state of charge of the battery cell 30 is recorded as 12:00, and then the specific time when the battery cell 30 is powered off from 100% state of charge to calculate the current state of charge of the battery cell 30 is recorded as 15:00, then the duration t between the two times is 3 hours. The nominal power of the battery cell 30 can be the theoretical value of the battery cell 30. The system uses the obtained data through the set calculation formula S1=100%-(I×t)/C0, where I, t and C0 are all known quantities, and finally calculates the current state of charge of the battery cell 30. In addition, the calculation formula S1=100%-(I×t)/C0 can be obtained by the ampere-hour integration method.

如此，可进一步通过电芯30的当前荷电状态对应的当前开路电压小于或等于预设开路电压时，确保电源对电芯30进行充电，使得电芯30与电源断开连接时保持100％荷电状态。In this way, when the current open circuit voltage corresponding to the current charge state of the battery cell 30 is less than or equal to the preset open circuit voltage, the power supply can be ensured to charge the battery cell 30 so that the battery cell 30 maintains a 100% charge state when disconnected from the power supply.
具体地，在一个实施方式中，系统可获取到电芯30的充电曲线，从电芯30的充电曲线中可查找到电芯30的荷电状态对应的开路电压。因此，根据充电曲线，在得到预设荷电状态的情况下可查找到对用的预设开路电压，再根据电芯30的当前荷电状态查找对应的当前开路电压。在一个实施方式中，在当前开路电压小于或等于预设开路电压的情况下，可控制电源对电芯30充电。在一个实施方式中，在当前开路电压大于预设开路电压的情况下，可保持电芯30的当前状态，不对电芯30进行充电。也就是说，进一步通过电芯30的当前荷电状态对应的当前开路电压小于或等于预设开路电压时，确保电源对电芯30进行充电，使得电芯30与电源断开连接时保持100％荷电状态。Specifically, in one embodiment, the system can obtain the charging curve of the battery cell 30, and the open circuit voltage corresponding to the state of charge of the battery cell 30 can be found from the charging curve of the battery cell 30. Therefore, according to the charging curve, the preset open circuit voltage for use can be found when the preset state of charge is obtained, and then the corresponding current open circuit voltage can be found according to the current state of charge of the battery cell 30. In one embodiment, when the current open circuit voltage is less than or equal to the preset open circuit voltage, the power supply can be controlled to charge the battery cell 30. In one embodiment, when the current open circuit voltage is greater than the preset open circuit voltage, the current state of the battery cell 30 can be maintained and the battery cell 30 is not charged. That is to say, when the current open circuit voltage corresponding to the current state of charge of the battery cell 30 is less than or equal to the preset open circuit voltage, it is ensured that the power supply charges the battery cell 30, so that the battery cell 30 maintains a 100% charge state when it is disconnected from the power supply.
需要说明的是，在其他实施方式中，当多个电芯30组装形成电池包时，电源连接电池包，系统可检测到每个电芯30的开路电压，每个电芯30的开路电压中的最高开路电压小于或等于预设开路电压的情况下，可控制电源对电池包充电。每个电芯30的开路电压中的最高开路电压大于预设开路电压的情况下，可保持电池包的当前状态。此时的预设开路电压指的是，电池包的预设荷电状态下对应的预设开路电压。It should be noted that, in other embodiments, when a plurality of battery cells 30 are assembled to form a battery pack, a power source is connected to the battery pack, and the system can detect the open circuit voltage of each battery cell 30. When the highest open circuit voltage among the open circuit voltages of each battery cell 30 is less than or equal to the preset open circuit voltage, the power source can be controlled to charge the battery pack. When the highest open circuit voltage among the open circuit voltages of each battery cell 30 is greater than the preset open circuit voltage, the current state of the battery pack can be maintained. The preset open circuit voltage at this time refers to the preset open circuit voltage corresponding to the preset charge state of the battery pack.
