When the preset information of the battery management needs to be adjusted, after professional verification, a technician can modify preset data through a control program writing port or a module. The user can connect the standard display device through the display interface to consult the parameters of the battery. When the battery is abnormal, the processor actively sends the abnormality related information to a user and a professional technician responsible for the device through a data interaction standard interface or module so as to remind the user of carrying out necessary abnormality treatment. When the protection board is abnormal or damaged, each string of battery cells of the intelligent supplementary reset storage battery is relatively independent on the premise that the switch components on the battery strings are completely normal.
As shown in fig. 2, each string of battery cells is directly associated with 6 switch elements, when the protection board determines that a certain string of battery cells should be a charging group through comparing the collected information with the pre-stored management parameters, the central processing unit sends out an instruction to drive K3 and K4 to be opened through the power amplifier, and simultaneously, K5, K6, K1 and K2 are all closed. Thus, the micro-control driving switch element enables the battery cell string to reach the state, namely the charging storage state, and the combination of a plurality of strings of the states is the charging group. The battery cell strings in the charging group are placed in high-current quick charge, low-current slow charge or saturated to be replaced. When the micro-control driving switch element is used for closing K3 and K4, and K5 and K6 and K1 and K2 are all opened, the cell strings in the state are placed in a discharging state, and the cell string combination of a plurality of strings in the state is defined as a discharging group.

When the four strings of electric cells of the first string, the second string, the third string, the fourth string and the like are discharge groups, K3 and K4 of each of the electric cells are connected, and the series storage battery pack connected end to end from the first string to the fourth string is formed. After a certain period of discharge, if the discharge parameters of the first string are first close to or reach the protection preset, then its associated K3 and K4 are turned off, while K5, K6 are turned on, and K3 and K4 on the original fifth string are turned on, as the tail string of the discharge group is connected to the discharge group. The K1 and the K2 of the original first string are sequentially connected, and the battery cells of the first string are combined into a charging group for charging. If the cost is required to be reduced, the reliability of the discharging operation of the battery is improved, and the switches at the K5 and the K6 can be used for randomly replacing one switch component according to the actual arrangement metal.
