What is the Most Suitable Way of Electric Vehicle Charging?

Electric vehicle range is getting longer and its popularity is increasing. There are two types of electric vehicle charging: slow charging and fast charging. Which one is the most suitable?

1. Comparison of slow charging and fast charging


Slow charging at home is cheaper. If the cost is about 50 cents per kilowatt-hour, electric vehicle charging can take advantage of off-peak electricity at night, which makes the price even lower. It costs about 20 yuan to fully charge and it can drive 250 kilometers. That is about 8 cents per kilometer, which is very economical. Charging stations have two components, basic electricity fee of one yuan per kilowatt-hour and a service fee of less than one yuan per kilowatt-hour (different regions have different fees). Compared with conventional vehicles, electric vehicles are still very economical.


Home charging is very convenient and evc electric vehicle charger is also very portable. However, the disadvantage is that charging time is too long, and it is inconvenient to use an evc electric vehicle charger during long distance trips. Charging stations are fast, and if you are out of town, it is the only choice. There are many charging stations in some cities, but they are concentrated in fewer areas, making it difficult for out-of-town car owners to find charging stations.

Effect on battery life

The higher the power when the battery is charged, the greater the current, the more heat generated, and the higher the temperature. The optimum temperature for charging is around 20℃. Slow home charging, except during the summer, the battery temperature is not higher than 40℃. Fast charging at a charging station, except during the winter, the battery temperature is higher than 50℃ when charging. If it exceeds 50℃, it will seriously affect battery life.

2. What is the best way to conduct electric vehicle charging?

After comparison, it is best to use home charging whenever possible. What issues should be aware of during electric vehicle charging? First, if the electric vehicle battery is not a lithium battery, it should be charged frequently, and if the battery capacity is less than 65%, it should be charged. Electric vehicles should not be parked for long periods of time while lacking power, and should be charged in a timely manner. If it is a lithium-ion battery, this is not a problem. The battery should not be overcharged or overdischarged during charging, as this will affect battery life.

When the battery is charging, all electrical appliances in the vehicle must be turned off to prevent simultaneous charging and discharging, which will cause a large current through the battery and affect battery life. Finally, the charging plug must be inserted firmly and completely to prevent loose connections. Otherwise, the plug connection will produce a large amount of heat, which may burn out the plug and even cause a fire.
