In the winter, the issue of electric vehicles has become the most concerned hot topic. Many people will feel that in winter, electric vehicles cannot run, and the charging time is short. Why do electric vehicles not ride far in winter?

In winter, when the battery is in a low temperature environment, the battery cycle capacity is relatively low, the viscosity of the electrolyte increases, the chemical reaction resistance increases, and the charging time may be shortened (charging 70% below 5 °C). The charging capacity is 60%–70%, and the discharge capacity is 50%. %–60%, the mileage is reduced (not far).

This will not only make many people feel that the battery is not durable, and complain that the quality of the battery is not good enough, in fact, your care is very important to the quality of the battery.

Why don’t electric vehicle batteries have these problems in summer? Is it true that the battery is really afraid of cold?

When the outdoor temperature is too low in winter, when charging the battery of an electric vehicle, you should try to choose it indoors, because the best ambient temperature for battery charging is 25 °C, and charging indoors is conducive to enhancing the battery’s power storage capacity. In addition, in winter, the outdoor temperature is cold, and the battery is easy to freeze and frost. It is best to leave it for a while before charging the battery, and wait until the surface temperature of the battery rises to close to room temperature and is fully dry before charging.

winter mileage calculation

Charging 70% multiplied by 60% discharge is about 42% of the mileage in summer.
