Types and characteristics of chargers

The classification of electric vehicle chargers is mainly as follows:

(1) According to the current, they can be divided into DC chargers and AC chargers.

(2) According to the power size, they can be divided into high-power chargers and low-power chargers.

(3) According to the charging frequency, they can be divided into industrial frequency chargers and high-frequency chargers.

(4) In addition, there are negative pulse chargers, three-stage chargers, transformer chargers, switching power supply chargers, etc.

Nowadays, the most widely used electric vehicle chargers are industrial frequency chargers and high-frequency chargers.

The characteristics of industrial frequency chargers are: large size, heavy weight, high power consumption, but reliable performance and low price.

The characteristics of high-frequency chargers are: small size, light weight, short charging time, good high current discharge performance, high efficiency, and intelligent activation function, which is conducive to the full dissolution, penetration and diffusion of battery activation substances, and the electrochemical reaction and concentration polarization are fully and thoroughly activated and fully utilized. Battery energy is basically fully activated and exerted, and its service life is extended, which is something that traditional thyristor chargers cannot do. High-frequency chargers truly embody the characteristics of safe, fast, efficient, and cost-effective charging technology.

In addition, with the advancement of science and technology and people's continuous in-depth research on charger technology, many new chargers have emerged, such as: high-power intelligent high-frequency chargers, thyristor rectifier chargers, etc. They are based on the original chargers, and have made great progress in charging efficiency, charging time, charging safety protection, and charging automation management, representing the trend and direction of future charger development.
