What is the reason why electric car batteries can't run far in winter?

As the temperature gradually decreases, we will find that the electric car is running closer and closer. What is the reason for this? Is the battery not working? However, some cars are obviously not long ago to change the battery, how can it not go far?

According to technicians at the battery plant, as the temperature decreases, the material activity in the lead-acid battery will decrease, the battery's storage capacity will weaken, and the capacity will shrink.

When the temperature is 25 °C, the charge and discharge of the lead-acid battery is in an optimal state. When the temperature drops below 10 °C, the amount of electricity stored in lead-acid batteries will be reduced by 20-30 %. When the temperature drops below 0 °C, the stored electricity will be reduced by 30 % -50 % or even more, because the active substance content contained in the battery, the temperature will drop, the active substance will not decompose sufficiently, and the amount of electricity will decrease, which is a normal phenomenon.

In addition, technicians also remind the majority of electric car users that with the reduction of temperature, consumers should use batteries correctly, which is also a good way to extend battery life.

When the temperature drops in winter, it is best not to charge outdoors. The temperature outside is low, the charging effect of the battery will be greatly reduced, and the charging ability will be reduced, resulting in a low battery life. When the temperature is low, it is best to charge in a warm room in order to better use the battery's recharging capacity.

The battery charging time should be extended appropriately. For example, the battery can be filled in eight hours in summer and about 10 hours in winter.

In addition, during the cycling process of electric vehicles, do not frequently brake and frequently start, usually pay attention to the moderate pressure of the tire, which can also extend the battery life.

The weather is cold, electric car battery run is not far is very normal, do not worry excessively, wait until the weather is warmer. When the temperature rises, the battery will return to normal.
