S1, judging whether a preset power-deficient power supplementing condition is met.
In specific implementation, the energy storage battery and the charging device are firstly connected physically, and the BMS is electrified. After the BMS is electrified, whether a preset power-deficient power-supplementing condition is met is firstly judged, namely whether the battery is in a power-deficient state currently is judged. The condition of supplementing electricity for the power shortage can be set by those skilled in the art, and the invention is not particularly limited.
In an embodiment, the step of determining whether the preset power-loss power-supply condition is satisfied includes the following steps:
s11, judging whether a power-deficient power supplementing instruction is received.
In a specific implementation, the power shortage and supplement instruction may be remotely sent by an operator or input through an input device (such as a key and a man-machine interaction interface) on the energy storage battery, and the invention is not particularly limited. That is, when the operator determines that the energy storage battery is in the power shortage state, the operator can send a power shortage and power supplement instruction to the BMS.
And S12, if the power-deficiency power-supply instruction is received, judging that the preset power-deficiency power-supply condition is met.

If yes, the energy storage battery is in the state of power shortage currently.
The first voltage threshold and the second voltage threshold are set by those skilled in the art, and the present invention is not particularly limited.

When the energy storage battery is in a power shortage state, the BMS enters a power supplementing mode; when the energy storage battery is in a normal state (without power shortage), the BMS enters a normal mode.
In the embodiment of the invention, when the preset power-deficiency power-supplementing condition is met, the BMS enters a preset power-supplementing mode, and the monitoring of the under-voltage faults of the battery in the preset abnormal fault list is stopped in the power-supplementing mode. Because the under-voltage fault of the battery is not monitored, the BMS can not monitor the abnormal battery power shortage, and the charging function of the energy storage battery can be normally started at the moment.

In specific implementation, the charging function of the energy storage battery is started, so that the energy storage battery is charged, the electric energy of the energy storage battery can be recovered, and the energy storage battery enters a normal state. Meanwhile, as the BMS is not forced to be closed, the BMS can monitor the charging process of the energy storage battery, namely, monitor parameters such as charging current, charging voltage, battery capacity and the like, and avoid the occurrence of over-voltage, over-charging and the like, thereby greatly improving the safety of the charging process.

In addition, manual delivery of charging is also supported.
According to the technical scheme, whether the preset power-deficiency power-supplementing condition is met is judged; if the preset power-deficiency power-supplementing condition is met, entering a preset power-supplementing mode, and stopping monitoring the under-voltage faults of the battery in a preset abnormal fault list in the power-supplementing mode; the charging function of the energy storage battery is started, so that the charging function of the energy storage battery can be normally started under the condition of power shortage of the energy storage battery, the BMS can carry out safety monitoring on the charging process, the safety is greatly improved, meanwhile, the manual intervention through an upper computer is not needed, and the operation process is simple.

In a specific implementation, if the minimum value of the cell voltage of the energy storage battery is greater than the preset third voltage threshold, this indicates that the voltage of the energy storage battery has recovered to be normal, and then the preset normal mode is entered.
In the normal mode, all faults in a preset abnormal fault list are monitored, so that the faults of the energy storage battery can be found in time, corresponding countermeasures can be made in time, and the safety is greatly improved. Simultaneously, the discharging function of the energy storage battery is allowed to be started, so that the energy storage battery can normally provide electric energy.
