Water E nergy Control Box
Adjust the water temperature of the cooler by controlling the rotating speed of the cooling system motor. Finally, the function of controlling the temperature of the cooling system is achieved. The control unit has the function of self-diagnosis. During the operation of the cooling system, the cooling control system can reliably record and store relevant information such as running state and faults, and can exchange data with the portable PC through the standard maintenance port (Ethernet). The control unit has fault recording function. The fault information includes at least: the fault code, the time when the fault occurred and disappeared, and the number of repeated failures. TRDP real-time communication system is adopted for communication of cooling system.

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.

Auxiliary converter
The traction converter is internally integrated with three traction inverter modules, the main purpose of which is to convert the DC voltage obtained from the converter into three-phase voltage with frequency conversion and transformation, which is used to control the traction motor to drive the vehicle to run in traction, inertia and braking conditions. The IGBT semiconductor devices of the traction converter are effectively cooled by circulating water cooling, and the structure of the inverter is very compact. Through internal and external cooling cycles, the heat of the inverter is effectively transferred out to prevent overheating. Two traction inverter modules and one auxiliary inverter module are integrated in the traction/auxiliary converter. Apart from the traction drive function, it also takes on the function of auxiliary power supply, which can convert DC voltage into three-phase sine wave voltage and supply power for vehicle AC load.
