The charging current is quite low, about 15A. This kind of charging is called conventional charging (ordinary charging). Conventional battery charging methods adopt constant voltage or constant current charging with small current. Generally, the charging time is 5-8 hours, or even more than 10-20 hours.
Fast charging, also known as emergency charging, provides short-term charging service for electric vehicles within 20 minutes to 2 hours of parking with a large current. The general charging current is 150 ~ 400A.
Battery is the only energy source of pure electric vehicle. It not only supplies the electric energy required for driving the vehicle, but also supplies the working power supply for various auxiliary devices on the vehicle.
Before the battery is installed on the vehicle, it needs to be combined into a low-voltage power supply with the required voltage of 12V or 24V through series and parallel connection, while the motor drive is generally required to be a high-voltage power supply, and the required voltage level is also different due to different motor types.
Precautions for charging pure electric vehicles
1. First of all, you should master the correct charging time. It takes a longer time to supplement energy for pure electric vehicles. Take the JAC iev6e sports model as an example. If you choose the home charging pile for charging, it takes nearly 8 hours to recharge the battery. If you choose the fast charging pile, it also takes 40 minutes to recharge 80%. Get into the habit of charging regularly. Don't wait until the power is too low.
2. The battery should not be overcharged or discharged. Overcharge and discharge of the battery will reduce its service life. Any product using batteries should not be "over discharged", and pure electric vehicles are no exception. Although the battery pack is designed with a protection system, if you often drive the car to the "red light", it will certainly affect the service life of the battery pack. And the charging shall be stopped immediately after being fully charged.
3. Turn off the power in the car when charging. When your car is charging, be sure to turn off the electrical equipment, such as the stereo and air conditioner. Because consuming electricity while charging will accelerate the loss of the battery and cause the battery to heat up. When the fuel truck goes to the gas station to refuel, the engine will also be turned off. The same is true for charging. Develop good habits. When charging, you may as well go to the coffee shop next door to have a rest, refresh yourself and prepare for the next trip.
4. Avoid heating the charging plug during charging. Loose 220 volt power plug or charger output plug, oxidation of contact surface and other phenomena will cause the plug to heat up. Too long heating time will cause short circuit or poor contact of the plug, damage the charger and battery, and bring you unnecessary losses. Therefore, in case of any of the above conditions, the oxide shall be removed or the connector shall be replaced in time.
As the power source of the automobile, the automobile battery is the heart of the automobile and provides a continuous driving force for the automobile. Therefore, in addition to the battery, motor and electronic control guarantee of 150000 km in 8 years as promised by the manufacturer, car owners also pay attention to daily charging details at ordinary times to maximize the service life of electric vehicles and avoid some vehicle failures and safety problems.
