As an energy supply device for electric vehicles, the charging function of electric vehicle charging piles is related to the service life and charging time of battery packs. This is also one aspect that consumers care about before purchasing an electric car. The basic principle of electric vehicle charger planning is to achieve fast, efficient, safe, and reasonable power supply for power batteries.
In addition, the applicability of the charger to various power batteries should also be considered. The control system composition of the fast charger: The control system of the fast charger adopts an intelligent variable pulse charging method, which uses charging current pulses, including charging pulse T1, intermittent pulse T2, and discharge pulse T3
Plan for chargers in above ground charging stations. The plan for a charger in an above ground charging station consists of a rectifier that can convert input AC power into DC power and a power converter that can adjust DC power. By inserting a plug with wires into the matching socket on the electric vehicle, DC power is input into the battery to charge it.
The charger is equipped with a locking lever to facilitate inserting and removing the plug, and together with the lever, it 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 station, and many details should be continuously improved in practical applications, which has been quickly applied in the plan.
