How to Solve the Home Charging Problem for New Energy Vehicles?
1 Answers
New energy vehicles can be directly charged at home with 220V. The following is an introduction to charging new energy vehicles: 1. Charging with a three-hole socket: Use a standard plug socket with a rated current not exceeding 16A to charge directly at home, which takes about 8-10 hours to fully charge. 2. Charging with an AC charging pile: Charge directly on the AC grid with higher current using a charging pile, which takes about 4 hours. The power of slow charging piles is usually 3.5kW and 7kW, and this value depends on the rated input power of the onboard charger. For single-phase AC charging, the rated input current of the onboard charger is currently divided into two mainstream types: 16A and 32A, resulting in 16*220≍3.5kW and 32*220≍7kW. 3. Charging with a DC charging pile: When connecting an electric vehicle to the AC grid or DC grid, a DC power supply device with control guidance function is used. Generally, only pure electric vehicles on the market are equipped with DC charging function, which is the so-called "fast charging". Fast charging takes a short time, as the high-power onboard DC charger directly outputs DC to charge the vehicle battery. The power of fast charging piles on the market ranges from 30kW to over 100kW, and the charging time also varies from a few minutes to 2 hours.
