Car Battery Charger

As the power supply device of electric vehicle, the performance of the Car Battery Charger is related to the working life and charging time of the Battery Pack. It is the basic principle of electric car charger design to realize fast, efficient, safe and reasonable power supply for power battery. In addition, the applicability of charger to various power batteries should also be considered.

At present, the charging mode of electric car is mainly contact charging, which is divided into AC (AC) slow charge and DC (DC) quick charge

For AC slow charging, each electric car has an on-board charger (OBC), which is mainly used in residential homes or work place. Generally, the charging power is less than 10kW, the charging current is less than 50A, and the electric car can only run about 10 kilometers after one hour.

For DC quick charge, it is mainly used in expressway, public facilities, etc. The charging power is generally greater than 50kW, and the charging current is greater than 100A. It is generally required that 80% of the electricity can be filled within half an hour to one hour.
