Notes:
[1]. Output current: when output current is no more than 600 V, the charger can output the max current;
[2]. Output mode:
â‘ Alternative output for double guns: insert the two guns to two electric vehicles at the same time and the charger can begin to charge automatically according to demand. Charging will automatically switch to the other vehicle after one is fully charged and only one can be charged at one time;
â‘¡ Simultaneous output for double guns: insert the two guns to two electric vehicles at the same time and the charger will automatically and equally divide power to the guns to support the simultaneous charging of two vehicles;
â‘¢ Output by turns for four guns: insert the four guns to four electric vehicles at the same time and the charger can begin to charge automatically according to demand. Charging will automatically switch to the another vehicle after one is fully charged and only one can be charged at one time;
Prohibit inserting the two guns of the single DC charger to the same vehicle, otherwise the charger and the vehicle will be damaged!
[3]. Auxiliary supply:
â‘ DC charger outputs DC 12 V auxiliary supply by default, which is compliant with GB/T 18487.1-2015. When used to charge BMS, it can supply power for the electric vehicle of DC 12 V grade;
â‘¡ Before the issue of GB/T 18487.1-2015, only electric vehicle and charger of 12 V and 24 V grades are on the market and these two types cannot be mixed. The DC charger of the Company, under the special requirement from customer, can supply DC 24 V or DC 12 V/DC 24 V double-switch auxiliary supply system!
Unless otherwise specified, the default auxiliary supply is DC 12 V. Therefore, please make sure to confirm the power supply type for the BMS of electric vehicle!
