In specific implementation, the battery may detect the charging current value of the electric core set through a galvanometer connected with the electric core set and the control unit, and then determine the charging voltage value according to the charging current value and the battery specification, or may directly detect the charging voltage value of the electric core set through a voltage detector connected with the electric core set and the control unit, so as to adjust the working state of the battery.
(3) And (3) a discharge low-voltage protection strategy: and judging whether the discharge voltage is low or not by comparing the discharge voltage in the electric quantity parameter with a preset discharge voltage threshold value, and performing corresponding measures such as stopping discharge and the like when the low voltage is determined.
In specific implementation, the battery may detect the discharging current value of the electric core assembly through a galvanometer connected with the electric core assembly and the control unit, and then determine the discharging voltage value according to the discharging current value and the battery specification, or may directly detect the discharging voltage value of the electric core assembly through a voltage detector connected with the electric core assembly and the control unit, so as to adjust the working state of the battery.
(4) And (3) a discharge overcurrent protection strategy: and judging whether the discharge current is over-current or not by comparing the discharge current in the electric quantity parameter with a preset discharge current threshold value, and performing corresponding measures such as stopping discharge and the like when the over-current is determined.
When the battery is specifically implemented, the discharge current value of the electric core group is detected by the battery through the galvanometer connected with the electric core group and the control unit, the discharge current value is transmitted to the control unit, and the control unit adjusts the working state of the battery when determining that the discharge current value exceeds a preset second threshold range.

The second temperature threshold range may be a specific value according to actual requirements, and it should be noted that the first temperature threshold range is higher than the second temperature threshold range.
(8) Storage self-discharge protection strategy: according to the electric quantity parameter and the preset rule, when the battery is stored for a certain time or the circuit is stored for a certain range, the battery is automatically discharged, so that the service life of the battery is prolonged.
When the method is specifically implemented, the battery counts the time length that the battery stops supplying power to the outside through the timer and exceeds the first preset time length, the control unit is informed to control the electric core group to discharge to the first preset electric quantity range, and when the battery stops supplying power to the outside, the electric core group is controlled to discharge to the second preset electric quantity range.

(10) Charging activation protection strategy: according to the electric quantity parameter, when the battery service time is zero or the battery deep sleep time reaches a preset time threshold, the battery circuit can be activated only by charging first, so that the safety of the battery is protected.
(11) Emergency protection strategy: and according to the electric quantity parameter, when the electric quantity of the battery is determined to be reduced to a preset circuit threshold value, the battery is closed after meeting the preset requirement of the external equipment. If the battery power is determined to be too low, the external device is powered off after the external device performs storage or transmission operation with high priority.
Certainly, when the number of the battery cells in the battery is greater than 1, a balancing strategy and a charging and discharging strategy can be further performed, the balancing strategy is to control the battery cells to be charged or discharged independently when the voltage and the electric quantity of one of the battery cells are determined to be different according to the electric quantity parameters, and the charging and discharging strategy is to adjust partial battery cells to be discharged and partial battery cells to be charged according to the state information.
In specific implementation, when the battery pack includes a plurality of battery cells, and when it is determined that a parameter of a target battery cell in the plurality of battery cells is inconsistent with parameters of other battery cells, the control unit charges or discharges the target battery cell until the parameter of the target battery cell is consistent with the parameters of the other battery cells, and the target battery cell is any one of the plurality of battery cells.
