GW-LF series 6.6KW on-board charger is designed according to national standards and is a product that provides energy replenishment for vehicle power batteries. It meets the new national standards CC/CP, electronic lock, and temperature detection interface. The charger adopts CAN bus control to achieve information interaction with the vehicle BMS/VCU and feedback of working status. This product not only has the advantages of high efficiency, small size, high stability, and long life, but also has the characteristics of high protection level, high reliability, and complete protection functions. It is an ideal power supply for charging electric vehicles. The product has a built-in thermal sensing device with overheating protection function and can automatically recover. The fully sealed process and the protection level of up to IP67 can ensure that it can work in any complex environment without causing failures.
