On-Board Charger ATS

On-board charger (OBC) converts the AC power of the charging station (EVSE) into DC power to charge the EV battery. Currently common OBC power specifications include 3.3kW, 6.6kW, 11kW, and 22kW. However, the future will bring increasing numbers of bidirectional on-board chargers (BOBCs) that apply to the EV through V2X modes. Chroma ATE provides test items that comply with GB/T 40432 and other relevant test standards, assisting users with complete verification of various application modes on the unit under test (UUT).
