Technical Realization for Charging Pile

As the energy supply device of electric vehicle, the charging performance of electric vehicle charging pile is related to the service life and charging time of battery pack. This is also one of the most concerned aspects before consumers buy electric vehicles. The basic principle of electric vehicle charger design is to realize fast, efficient, safe and reasonable power supply to the power battery. In addition, the applicability of the charger to various power batteries should be considered.


Technical Realization for Charging Pile


Control system composition of fast charger:


Intelligent variable pulse charging mode is adopted, that is, charging current pulse is adopted, including charging pulse T1, intermittent pulse T2 and discharge pulse T3.

Scheme of charger in ground charging station


The charger in the ground charging station is composed of a rectifier that can convert the input AC power into DC power and a power converter that can adjust the DC power. By inserting the plug with wire into the supporting socket on the electric vehicle, the DC energy is input into the battery to charge it. The charger is equipped with a locking lever to facilitate the insertion and removal of the plug, and the lever can also provide a signal to confirm that it has been locked to ensure safety. According to the communication between the charger and the on-board battery management system, the power converter can adjust the DC charging power online, and the charger can display the charging voltage, charging current, charging amount and charging cost. This is only the basic principle of the charging pile. Many details should be continuously improved in practical application, and the most convenient use scheme has been obtained.
