The battery cabinet contains one (1) 40 A battery disconnect circuit breaker and provides alarm leads attached to the common contacts of the breaker. Battery cabinets may be daisy chained as shown in Figure 7 to increase the reserve time.
In short, the working principle of the DC screen is to convert AC power into DC power to provide power for the protection of electrical secondary equipment, operating mechanism and indicator light. Under normal circumstances, the charging unit will charge the battery and provide DC power to the regular load. 1.
The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid.
Connect the power system’s battery cable terminated in an Anderson connector to the first battery cabinet’s battery cable terminated in a mating Anderson connector. Connect the second battery cabinet’s battery cable terminated in an Anderson connector to the fixed mating Anderson connector located on the first battery cabinet.
The voltage of the high voltage battery will vary according to the vehicle type and manufacturer. If fully charged high voltage batteries may have an electrical potential from 60V up to several hundred volts DC.
The DC screen with microcomputer control adds a central monitoring unit, making the interface of the DC screen more friendly, and the operation and control simpler. 5、 What is the working principle of DC screen?
