Multi-energy storage unit cooperative charging method

The invention provides a multi-energy storage unit cooperative charging method, and the method comprises the steps: automatically adjusting the charging power corresponding to each energy storage unit according to the maximum charging power which can be provided by a current power supply system and the energy storage state of each energy storage unit for a working condition that the available total charging power has a limit value; the function of improving the overall average charging speed of the energy storage device is achieved. Through reasonable distribution of the charging power of each energy storage unit, the charging time of each energy storage unit tends to be the same as much as possible, so that the available power limit of the system and the rated capacity of the charging controller are fully utilized, and the overall charging time of the multiple energy storage units is shortened. According to the invention, the charging power of each energy storage unit and the total charging power always chan
