How to maintain an electric fire truck in winter?

First, charge frequently in winter.

Develop good usage habits. Pure electric vehicles should develop the habit of charging on the same day of use. In winter, the battery has the problem of poor charging acceptance and insufficient charging.

The optimal ambient temperature for battery charging is 25 degrees Celsius, and it is best to charge indoors. In the cold winter situation, it is necessary to increase the charging voltage and extend the charging time, and take thermal insulation and anti-freezing measures, so as to ensure sufficient power and prolong the service life of the battery.

Second, winter riding is more helpful.

When the vehicle has just started, it should be accelerated slowly to avoid instantaneous rapid acceleration and damage to the pure electric vehicle accessories. On the premise of ensuring safety, braking and starting should be minimized during driving to save electric energy. When braking while driving, the speed control lever should be released to avoid damage to the motor and other pure electric vehicle accessories.

In heavy load situations such as uphill and headwind, use the pedal to assist. When getting off the car to push, the power should be turned off to prevent an accident when the car starts suddenly due to the unintentional rotation of the speed control handle.

Third, the charging interface should be kept clean, and no water or other foreign objects can enter the charger interface, because this will easily cause a short circuit inside the charging interface of pure electric vehicles, which will affect the service life of the battery.

Fourth, maintenance should be carried out in winter.

Before going out, you should pay attention to check whether the parts of each new energy pure electric vehicle are good, such as whether the tire pressure is sufficient, whether the front and rear brakes are sensitive, whether the vehicle has abnormal noise, whether the screws are loose, and whether the battery is sufficient. In case of rain and snow and water, the center of the wheel hub should not be flooded with water, so as to prolong the life of the battery and motor of the pure electric vehicle. After rain and snow, special attention should be paid to the maintenance of electric vehicles.

It should also be lubricated frequently in winter. The front axle, rear axle, middle axle, flywheel, front fork, shock absorber rotation fulcrum and other parts of the new energy pure electric vehicle are scrubbed and lubricated once.

Fifth, adopting the correct battery usage habits can effectively extend the battery life of electric vehicles.

The battery is easy to run out in winter, so it is recommended to charge it at any time if possible, and fully charge it at any time. You must know that charging is a big part of the scrapping of pure electric vehicle batteries in winter! Therefore, try to keep the battery charging time at 6-10 hours in the case of low power, and do not charge it for a long time.

Frequent and long charging will cause the performance of the battery to deteriorate, the charging time is too short, and the battery can easily run out. It is best to have more than 10% battery power when charging.

Don't often drive too short distances;

Do not over-discharge, i.e. do not use the electrical appliances in the car for a long time after turning off the engine;

When parked for a long time, it should be charged regularly or the battery switch is turned off, or the negative pole of the battery is removed.
