Conventional charging (slow charging) is the charging method used by most pure electric vehicles, which uses the traditional way of constant voltage and constant current to charge the car. The charging current size is about 15A, taking a 120Ah battery as an example, charging should last at least 8 hours or more. This charging method is low-cost and stable, suitable for use at home, by connecting to the home grid, you can charge new energy vehicles at home at any time. Slow charging is not only convenient, but also saves time and cost, and at the same time is good for battery life, because the charging current is small and the loss of the battery is less. However, the disadvantage of slow charging is that the charging rate is slower and it takes longer to full the battery.
Fast charging (fast charging) is a method of fully dc ev charger charging an electric vehicle in a short period of time, usually requiring a higher charging current (150 to 400A) and a larger charging power (generally greater than 30kW). The fast charge can fully charge an electric car in 30 minutes to an hour, which is suitable for long trips or situations where charging is urgently needed. However, fast charging has a certain impact on battery life, because the heat generated by the battery will increase sharply during the rapid charging process, and a violent chemical reaction will occur inside the battery, which may affect the service life of the battery to a certain extent, thereby increasing the cost of later use of the electric vehicle.
In addition, there are some other charging methods, such as ev charging solutions home charging pile, public charging pile, fast charging station and charging network service, etc. These methods provide different charging convenience and flexibility, and users can choose the appropriate charging method according to their needs and circumstances.
To sum up, the best charging method for pure electric vehicles should be selected according to the actual situation and personal needs. For daily use and home charging, slow charging is a better choice because it has less impact on battery life. The fast charge is more suitable for emergency or long-distance travel.
