Chennic DC-DC Converter

Every gas vehicle on the market uses a belt driven alternator to generate 12 Volts DC to run the accessories (fans, pumps, headlights, heaters, etc). MR02EV has no alternator so a Chennic DC-DC converter is used to convert the 370 Volt main battery pack voltage to 12 Volts.
