Electric vehicle charger types and characteristics of chargers

The classification of electric vehicle chargers is mainly as follows:

(1) It can be divided into DC chargers and AC chargers based on the different currents.

(2) According to the different power size can be divided into high-power chargers and small power chargers.

(3) According to the different charging frequency can be divided into industrial frequency charger and high frequency charger.

(4) In addition, there are negative pulse charger, three-stage charger, transformer charger and switching power supply type charger and so on

Nowadays, electric vehicle charging is the most widely used industrial frequency charger and high frequency charger.

Industrial frequency charger is characterized by: large size, high weight, high power consumption, but reliable performance, cheap.

High-frequency charger is characterized by: small volume, low weight, short charging time, high-current discharge performance, high efficiency, with intelligent activation function, which is conducive to the full dissolution, penetration and diffusion of the battery activation material, electrochemical reaction and concentration polarization is sufficiently thorough, basically fully activate and play the battery energy, and extend its service life, is the traditional silicon controlled charger can not do. High-frequency charger truly embodies the safety, fast, efficient, cost-effective charging technology features.

In addition, with the progress of science and technology, as well as people's charger technology continues to deepen the research, many new chargers came into being, such as: high-power intelligent high-frequency chargers, silicon controlled rectifier chargers. They are on the basis of the original charger, take the long and make up for the short, no matter in the charging efficiency, charging time or in charging safety protection, charging automation management have made great progress, representing the future trend and direction of charger development.
