High voltage DC relays for new energy
vehicle solutions

Program Overview:As the main circuit of the new energy vehicle is DC and high voltage, the arc produced is difficult to extinguish. If the arc is not extinguished promptly and simply, it may lead to leakage electricity, fire, explosion and other extreme conditions. Therefore, the power supply circuit of the new energy vehicle must be equipped with high voltage DC relay which with a very strong arc extinguishing ability of the safety interruption equipment. Hongfa high voltage DC relay has the characteristics of fast operation, small volume, high arc extinguishing safety, high operational reliability and long life. After more than ten years of technological development, through technical input and R&D cooperation with many mainstream automobile and battery electric control plants at home and abroad, a number of mature product lines with high performance-price ratio have been formed, which have all-round product solutions for main circuit control, pre-charging circuit control and charging control, and are widely used in electric vehicles, hybrid electric vehicles and charging facilities.
