The service life of an electric vehicle battery is not only related to the product quality of the manufacturer and the system configuration of the electric vehicle, but also has a lot to do with the use and maintenance of the consumer. therefore. To make good use of electric vehicles, one is to carefully choose the brand, understand its quality status and service commitments, so as to obtain good electric vehicle products; the other is to understand and master some basic knowledge of the use and maintenance of batteries, as follows:
1. Keep the battery fully charged. When riding an electric vehicle every day, no matter 10-15Km , it should be recharged, so that the battery is in a "full state" for a long time, and it is charged on the same day. The plate is vulcanized and easy to drop.
2. Perform regular deep discharge: It is recommended to perform a deep discharge after two months of use, that is, long-distance riding until the under-voltage indicator flashes and the battery is used up, and then charge the battery capacity, so that you can understand the current battery capacity level and whether it is needed maintenance.
3. It is forbidden to store under power loss: storage under power loss will seriously affect the service life. For example, the longer the idle time, the more serious the damage to the battery.
4. Regular inspection: If you buy a new car with a continuous line of 50Km , the continuous line will be severely reduced within three months, such as more than ten kilometers. At this time, you can use a multimeter to check the voltage value of the battery external terminal. Generally, the full charge should be 39- 42 V, if it is less than a few volts, or the voltage of one battery in the battery box is lower than 10.5 V, it may be an internal single-cell short circuit. At this time, you should find a repair station to repair and replace the other two good batteries. Also check the charger failure.
5. The designed load capacity of the electric vehicle is 75Kg , so avoid carrying heavy objects. Please use your pedals to assist when starting and going uphill.
6. It is normal for the battery capacity to decrease with the temperature drop in winter. Taking 20 ℃ as the standard, generally- 10 ℃ capacity is 80% . Keep the surface of the battery clean for a long time. Do not expose to the sun when it exists, and place the car in a cool, ventilated and dry place
