Common questions about EV and charging stations

2021-06-05 11:44:08  FAQ

1. What is the difference between the cost per kilometer of an electric car and that of a regular car?

Ordinary cars cost about 0.8-1 yuan per kilometer, while electric cars cost about 0.1 yuan per kilometer.


2. Will there be any error in the display of the remaining battery power in the car?

The BMS system on the battery is responsible for estimating the remaining battery power, and the accuracy is generally high.


3. Will electric cars be equipped with batteries?

The batteries of electric vehicles are generally larger and heavier, and all models are not equipped with batteries at present.


4. What do I need to pay attention to for daily maintenance?

The charging pile equipment itself has a self-test function, and there will be an alarm display for abnormal conditions, so no special maintenance is needed for daily use.

5. What is the service life of electric car battery and the whole car?

The electric vehicles sold in the market need to go through national testing, including testing the cycle life and reliability of the battery. It can be said that electric vehicles that pass the national test can meet the needs of consumers. For example, BYD e6 (parameters|pictures) cab some have traveled nearly 300,000 kilometers, equivalent to private cars run 15 years. JAC Aiyi for 5 years 100,000 kilometers of battery life can be completely guaranteed. SAIC Passenger Vehicle Co., Ltd. launched a pure electric car E50 battery cycle life of 2,000 times, the service life can reach 10 years. The electric cars currently sold in China all make a quality assurance commitment to the battery, and the battery can be replaced free of charge during the warranty period, completely relieving consumers of their worries.


6. What is the type of battery used in electric vehicles?

Lithium-ion battery.


7. What is fast charging and slow charging?

Fast charging and slow charging is a relative concept, and the capacity of the battery itself is related. Taking the nominal capacity of a battery as C, using 0.1-0.3C current charging pile is slow charging, and greater than 0.3C is fast charging. For example, to charge a 2600mAh Li-ion battery, at this time C is equal to 2600mA, and the charging pile current is equal to 600mA for slow charging pile, while the same 600mA charging pile current is fast charging for a 1500mAh (at this time C=1500mA) battery.

8. What is the impact of slow charging and fast charging on the battery?

Slow charging has less impact on the battery, which is beneficial to the long-term cycle of the battery, but the charging pile time is long. Fast charging when the charging pile current is larger, easy to cause heat resulting in high temperature and affect the battery life. However, there are battery management systems (BMS) in electric vehicles, which can monitor the battery temperature and charging pile current in real time to ensure that the battery can reach its designed life.
