In winter, the temperature drops, and the battery life of electric vehicles also decreases. In fact, this is a normal phenomenon mainly caused by the following two reasons.
01
When the temperature drops, the storage capacity of the battery decreases.
When the temperature decreases, the storage capacity of the battery decreases. When the temperature is lower than 15°C, the decrease in battery capacity will be more obvious. And every time the temperature drops by 1 degree, the usable capacity will drop by about 0.8%. When the temperature is zero, the battery capacity is only about 70% of normal.
02
The riding resistance increases, which affects the cruising range.
The temperature drops, and the air in the tires of electric vehicles will expand and contract with heat, causing the tire pressure to decrease, and the friction between the tires and the ground increases, and more energy is lost during riding. .
Pay attention to seven points to easily solve this problem.
1, cold and frequent charging
, pay attention to frequent charging, do not wait until the power is exhausted, and the battery power should not be less than 25% during charging. If it is less than 25%, it will be correct. The battery causes damage and affects the service life of the battery.
2, pay attention to the charging environment
cools down in autumn, charging mainly has the problems of poor charging acceptance and insufficient charging, resulting in battery loss. When charging, it should be placed in a warm environment, which will help ensure sufficient electricity, prevent irreversible sulfation, and extend the service life of the battery.
3. Pay attention to the charging time.
When the weather becomes cold, there will be more surplus electricity during charging than in summer. When charging, after the charger is turned on, you can float for another 1-2 hours, and also pay attention to the charging time Too long or too long will cause damage to the battery.
4. Try to avoid using fast charging piles
Many people are accustomed to using fast charging stations for charging, but it is precisely this method of using high-voltage and high-current pulses to quickly charge the battery in a short period of time through instantaneous high current, which is easy to cause damage to the battery Do not use this charging method as much as possible.
5. Avoid long-term power loss
Long-term power loss of electric vehicle batteries will vulcanize the plates. Some people will put the electric bicycle on the ground because the temperature is cold, and then ride the electric bicycle after the temperature rises. Electric bicycles should not be ridden for a long time and should be charged regularly to avoid battery damage caused by vulcanization.
6. Don't turn the handle too hard when riding.
Many car owners have the habit of rapid acceleration and sudden braking when riding. This habit will firstly have certain traffic safety hazards, and secondly, the sudden large and small current will affect electric vehicles. The performance of the battery shortens the service life.
7. The battery life has dropped significantly, and you need to go to a professional repair point for testing.
If the electric vehicle has a significant decrease in mileage when the temperature drops, or the battery has been used for more than two years, you can go to a regular electric vehicle shop or repair shop to test. May need to be replaced.
