OBC (On-Board Charger) is a component installed in new energy electric vehicles, which converts the AC power output from AC charging pile into high-voltage DC power to charge the high-voltage power battery of the vehicle.
VMAX started to develop OBC products of various specifications at the beginning of the company, and has accumulated rich experience related to onboard charging, and the corresponding products have been used in a large number of new energy vehicles of major domestic car manufacturers (SAIC, Geely, Chery, Changan, etc.).
