The high power charger of the car charging pile is a high power charger specially designed for medium and large pure electric vehicles, which can be mobile charging or vehicle mounted charging; the electric vehicle charger can communicate with the battery management system, receive the battery data from the battery management system, and the charging process adopts the appropriate method to form the single cell voltage in the battery not exceeding the upper limit, while the Beihai charging pile indicates that it can automatically stop charging when the battery management system sends out a When the battery management system sends out the information of serious battery failure, the charger can stop charging automatically.
The charger has panel operation and remote operation function, the charger is connected with the charger monitoring system through CAN bus, and all functions except closing and cutting off the input power can be completed on the monitoring computer. The charger has a fault alarm function and can actively send fault information to the monitoring system. The electric vehicle charger has protection functions such as input undervoltage, input overvoltage, output short-circuit, battery reverse connection, output overvoltage, over-temperature and battery failure.
The main features of the charger of the car charging pile:
1. The switching power supply control chip adopts imported military grade IC, the principle design of charger is optimized and reasonable, the production process is strict and perfect to ensure the safe operation of the machine.
2. The power switching tube adopts Nissan (IGBT) devices to improve the reliability and stability of the machine.
3. Digital meter displays charging voltage and charging current.
4. Timing function: manual timing charging mode can be selected (optional).
5. Perfect charging characteristics: constant current technology, constant current at the beginning of charging, so that each battery can be fully charged faster, with high charging efficiency and small temperature rise of the battery; automatic switching to constant voltage current limiting charging when the charging voltage reaches the upper limit voltage, which effectively improves the capacity conversion efficiency of the battery; trickle float charging equalizes the power received by the individual batteries to ensure that the capacity of the battery can be . Trickle float charging makes each single battery receive power evenly, ensuring that the battery capacity can be recovered to a large extent, effectively solving the phenomenon of unbalanced single voltage, avoiding the danger of over-voltage charging of the battery caused by the change of utility voltage and the end of battery charging, and greatly prolonging the service life of the battery.
