Charging control system for traction battery cell assembly of motor vehicle, sets usual capacity of input and output of converter for same operation in respective operating mode by capacity of cell assembly and circuit capacitor

摘要

The system (1) has an intermediate circuit capacitor (9) through which the traction battery cell assembly (2) is connected with the inverter (7). A direct current (DC)-DC regulator (10) works as high or low setting actuator in the direction of inverter of the traction battery cell assembly. The usual capacity of input and output of the DC-DC converter for same operation in the respective operating mode is set by the capacity of traction battery cell assembly and the intermediate circuit capacitor.
