Electric vehicles are becoming more and more popular with consumers. However, there are still some consumers who have concerns about the convenience and safety of EV charging. The following is an introduction to the principles of EV charging.
Electric vehicle charging principle
The most commonly used charger is a mobile phone charger. The charging principle is as follows:
The AC end of the charger is a two-plug plug, connected to a household socket, the DC end is a UEB interface, and then the professional charging cable is connected to the mobile phone charging port. Basic principle:
The basic principle of charging is to turn alternating current into direct current and charge the battery. It can be understood as:
(1) The power grid is the power supply, and the supply is alternating current, while the battery charging must be direct current;
(2) AC power cannot directly charge the battery, and it must be equipped with a charger to realize charging.
The principle of an electric vehicle charger is the same as that of a mobile phone charger. The difference is that electric cars are equipped with a much larger battery capacity than mobile phones, so the charger is much larger than the charger and has more auxiliary functions.
