Basic requirements of electric vehicles for charging systems

Safety: including personal safety of personnel and safety of power batteries.

Ease of use: with high intelligence, operators do not need to intervene too much in the charging process.

Economical: low-priced and high-performance charging equipment helps to reduce the cost of the entire electric vehicle and promote the commercialization of electric vehicles.

High efficiency: high efficiency is one of the important requirements for modern electric vehicle charging systems.

Low pollution: charging equipment using power electronics technology is a highly nonlinear device that will produce harmful harmonic pollution to the power supply network and other power supply equipment. Moreover, due to the low power factor of the charging equipment, when the load of the charging system increases, the impact on the power supply network cannot be ignored.

AC (slow) charging system

The AC (slow) charging system is mainly composed of power supply equipment (AC charging pile or household AC power supply), on-board charger, slow charging port, charging gun, high-voltage wiring harness, low-voltage control wiring harness, high-voltage control box, power battery, vehicle controller (VCU) and other components.

The AC charging pile uses a conduction method to provide AC power to electric vehicles with on-board chargers, provides a human-machine operation interface and an AC charging interface, and is a dedicated device with corresponding protection functions.The AC power provided by the AC ev charging pile (or household 16A power socket) is converted into high-voltage DC voltage after rectification, filtering and boosting by the on-board charger, and then connected to the power battery through the high-voltage control box.Tips:Basic Knowledge of Electric Vehicle Charging Systems 2

AC ev charging piles can be used in various large, medium and small electric vehicle charging stations. Its characteristics are low charging power, long battery charging time, and can make full use of off-peak hours for charging.

DC (fast) charging system

The DC (fast) charging system is mainly composed of a fast charging pile (DC charging pile), a fast charging interface, a high-voltage control box, a power battery, a vehicle controller, a high-voltage wiring harness, and a low-voltage control wiring harness.

The charging interface of the DC charging pile is a connector that physically connects the charging pile to the fast charging port of the electric vehicle to complete charging and control guidance.
