What is an electric vehicle charger?

Electric vehicle charger is an important device used to provide power for electric vehicles (EV). The following is a detailed answer about electric vehicle chargers, summarized in a clear structure:

1. Classification of electric vehicle chargers

On-board charger (OBC):

Also known as AC charger, installed on electric vehicles.

Connected to the AC socket through a socket and cable, it provides charging power to the electric vehicle with a three-phase or single-phase AC power supply.

Advantages: As long as there is an AC socket with the rated voltage of the charger, the electric vehicle can be charged.

Disadvantages: Limited by the space of the electric vehicle, the power is small, the output charging current is small, and the battery charging time is long.

Non-on-board charger:

Including slow chargers, fast chargers and super chargers.

Slow charger: The charging power is low, suitable for home or long-term parking.

Fast charger: has a high charging power and is suitable for fast charging in public places or long-distance travel.

Super charger: has an extremely high charging power and can fully charge electric vehicles in a very short time.

2. Interface standards for electric vehicle chargers

CHAdeMO: designed for powerful DC charging stations, with a fast charging speed.

GB/T: Chinese standard electric vehicle plug, divided into AC and DC, with a charging power of up to 190kW.

CCS1 (US standard): supports fast and slow charging, converts AC power to DC power through the inverter in the car, and the charging speed can be increased to a very fast level.

Mennekes Type 2 and CCS2: used by European and some Chinese electric vehicles, supporting charging from single-phase and three-phase power grids.

3. Working principle of electric vehicle chargers

AC input: The charger first obtains AC power from an external power source and converts AC power to DC power through a rectifier.

DC output: The rectified DC power is further adjusted by the charger's control circuit to ensure that the output DC voltage and current meet the requirements of electric vehicles.

Charging protection: The charger monitors the charging current and voltage. Once the set safety range is exceeded, the charger will automatically disconnect the charging to avoid overcharging of the electric vehicle battery.

4. Development trend of electric vehicle chargers

Super fast charging technology: further shorten the charging time of electric vehicles and improve charging efficiency.

Wireless charging technology: using the principle of electromagnetic induction, the wireless charging device embedded in the ground and the receiving coil on the base of the electric vehicle are used to transmit electric energy, improving the convenience and safety of charging.

Smart charging technology: combined with the Internet of Things technology, the intelligent management of charging equipment is realized, and the charging efficiency and user experience are improved.

Summary: Electric vehicle chargers are an indispensable and important part of electric vehicles. With the continuous development of technology, the charging speed, safety and intelligence of chargers will continue to improve, providing strong support for the popularization and development of electric vehicles.
