The 65kWDCDC module is a bidirectional current-controllable non-isolated conversion device that connects the low-voltage flow energy storage battery system and the DC bus. During operation, the BAT side voltage is 20V lower than the BUS side voltage. The BAT side can be used to step up the voltage from the BUS side, and the BUS side can be used to step down the voltage from the BAT side.
