With the rapid development of the new energy electric vehicle market, many consumers buy electric vehicles. The accessory market brought by the charging method of electric vehicles has become a rookie in the development market of new energy electric vehicles.

New energy electric vehicles can be directly plugged in and charged with 220V household power. When consumers buy a car, the manufacturer will give away a home charger. However, the charging power of the on-board charger presented by the manufacturer is very low, and most of the power is only 1.6KW. Taking an electric car on the market as an example, the battery capacity of an electric car is 16.9kWh, and the on-board charger is used. The time from 0 to full charge is 16.9kWh/1.6KW=10.5h. The maximum current carried by 220V household electricity is 16A. The maximum charging power is 220V*16A=3.5KW. It is directly plugged into a 220V 16A household socket for charging, with a charging power of about 3.3KW. It can perfectly match all new energy electric vehicles. Using a 3.5KW portable charging gun, the time from 0 to full charge is 16.9kWh/3.3KW=5.12 hours. It was twice as fast as the onboard charger that was sent when I bought the car.

Factors such as the specifications, models, and quality of electric vehicle charging cables also affect the charging power. The charging process puts forward higher requirements on the charging cable. The charging cable not only needs to have the function of power transmission but also needs to change the status of the vehicle and the power battery. The information is transferred to the charging pile for real-time interaction, and under necessary conditions, the charging action is controlled to complete the charging process safely and reliably.
