The AEM EV Combined Charging Unit (CCU) combines both an On-Board Charger (OBC) and a DC-DC Converter (DCDC). The OBC charges the HV Battery Pack by taking 120v or 240v AC energy f rom the grid, converting it to high voltage DC and charging the high voltage battery in the vehicle. The DC-DC converter takes the high voltage from the battery pack and converts it to low voltage to maintain the charge in the vehicles 12V battery. The DC-DC converter performs the duties that the alternator does in an ICE vehicle. The CCU is fully controlled by the VCU via the CAN bus and the OBC and DC-DC report voltage, current and status information back to the VCU. The DCDC LV output is rated at 91.5% efficiency at full load with a max continuous DCDC output of 178A @ 14V Compact design (275mm x 202mm x 68mm =3.8L volume) - 2.5x to 3x smaller than comparable units Lightweight (5.5kg, ~12 pounds) comparable units are typically 18-24 pounds Liquid cooled and temperature controlled for efficient thermal management The HV battery charger is rated at 93.5% efficiency at full load 6.6kw (32 amps) on board charger + 2.5kw DC-DC converter High voltage output over and under voltage protection High and low voltage output short circuit protection The CCU has the following protection functions: 350Vdc nominal output and up to 450Vdc max Input over and under voltage protection Plug-and-play with AEM's EV controls Over temperature protection Show more
