Product details

Product Function

Grasen electric vehicle charger front panel HMI adopts color liquid crystal touch display screen, it show output voltage, current, charging time, SOC, single battery voltage during charging. Parameter setting can be completed directly through liquid crystal touch screen.

Charger operation method is automatic charging: the system can automatically charge according to BMS request parameter and stop charging automatically after fully charged.

Charger itself has self protection function such as input over-voltage,input low voltage,output over current, output short circuit,output over voltage,over temperature protection,anti-reverse ,insulation test and emergency protection measures such as emergency stop button. 

DC charger with standard wireless communication module and wired interface and can submit charging information through wireless or wired network to realize background monitoring.


The series of electric vehicle charger combine the functions of charging stations and DC chargers and are composed of parallel charger modules with an automatic correction function of active power factor, and are provided with human-computer interaction, card swiping, billing, settlement, remote communications and control and other functions, as well as safety protection measures; it is a type of intelligent charging equipment used to directly charge pure electric buses and plug-in hybrid electric buses. Due to the small size, the equipment can be widely applied in bus transit depots, large parking lots, etc.
