Battery Charger
The charger drives all DC24V DC loads, and meets the charging requirements specified by the battery. It can float charge the battery according to the charging characteristics of the battery, and the battery box has the temperature compensation control function. When the train has no grid voltage, the capacity of the storage battery should be able to supply the internal emergency lighting, external lighting, emergency ventilation, on-board safety equipment, broadcasting, some display screens, communication system, etc. of the train for 30 minutes, and the train doors should be opened and closed once, and the auxiliary power supply can be started when the grid voltage is restored.
