About the charging technology of electric vehicle charging piles
The popularity of electric vehicles can be said to have added a power to environmental protection, so as to achieve no exhaust gas no pollution to the environment. The most indispensable thing for electric vehicles is the battery, but the battery needs charging equipment to store electricity, that is, the electric vehicle charging pile.
Nowadays, both first-tier cities, communities even individuals have begun to install electric vehicle charging piles, which has indeed brought people a lot of help. Next, the editor will give you a good introduction to the relevant knowledge of car charging piles.
On-board charging devices refer to devices installed on electric vehicles that use ground AC power grids on-board power sources to charge battery packs, including on-board chargers, on-board charging generator sets, operating energy recovery charging devices. Connect an AC power cable with a plug The cable is directly plugged into the charging socket of the electric vehicle to charge the battery. The vehicle-mounted charging device usually uses a contact charger with a simple structure convenient control, an induction charger. It is designed completely according to the type of on-board battery is highly targeted.
Non-vehicle charging devices, that is, ground charging devices, mainly include dedicated chargers, dedicated charging stations, universal chargers, charging stations for public places, etc. It can meet various charging methods of various batteries. Generally, the power, volume weight of non-car chargers are relatively large, so as to be able to adapt to various charging methods.
In addition, according to the different ways of energy conversion when charging electric vehicle batteries, charging devices can be divided into contact type inductive type. With the rapid development of power electronics technology variable current control technology, the maturity popularization of high-precision controllable variable current technology, the staged constant current charging mode has been basically replaced by a constant voltage current limiting charging mode in which the charging current charging voltage continuously change . The constant voltage current limiting charging mode dominates the charging process. The big problem of contact charging is its safety versatility. In order to make it meet the strict safety charging standards, many measures must be adopted in the circuit to enable the charging equipment to be safely charged in various environments. Constant voltage current limiting charging staged constant current charging are both contact charging technologies. The new electric vehicle induction charging technology is developing rapidly. The induction charger uses the transformer principle of a high frequency AC magnetic field to induce electric energy the original side of the vehicle to the secondary side of the vehicle to achieve the purpose of charging the battery. The major advantage of inductive charging is safety. This is because there is no direct point contact between the charger the vehicle. Even if the vehicle is charged in harsh weather, such as rain snow, there is no risk of electric shock.
