Emergency generator car battery regulation and control method, system, equipment and medium

The invention discloses an emergency power generation vehicle battery regulation and control method, system, device and medium, when an emergency power generation vehicle battery regulation and control request is received, the available capacity value and the battery voltage value of each emergency power generation vehicle battery are obtained, and the operation state of the emergency power generation vehicle battery is determined according to the battery voltage value and the available capacity value; and determining corresponding target batteries according to each operation state and a preset number threshold value, and determining output current values corresponding to the target batteries based on the available capacity values of all the target batteries. The technical problems that in the prior art, emergency generator car batteries serve as a standby power source of a direct-current power supply system, but the situation that multiple emergency generator car batteries are connected in a grid to supply p
