Electric car maintenance, the battery is the key. The problem about the electric car battery maintenance method, of course, the words of experts more credible, for this reason I consulted the battery technology experts, and finally get the following advice.
A, if long-term business trips, electric vehicles should be used when the battery for what treatment?
The battery must be fully charged after storage, and the battery must be replenished once a month to avoid long-term battery storage due to power loss, resulting in battery capacity decline due to sulfation of the plates, and even scrap. Therefore, when the battery is idle, it should be replenished once a month, so as to better maintain the battery health status.
Second, regular inspection of the battery
In the process of use, if the range of electric vehicles in a short period of time suddenly drop more than a dozen kilometers, it is likely that at least one of the batteries in the battery group has a broken cell, softening of the pole plate, the active material of the pole plate off and other short-circuit phenomenon. At this time, you should promptly go to a professional battery repair institution for inspection, repair or grouping. This can relatively extend the life of the battery pack and maximize savings.
Third, avoid high current discharge
When the electric car is starting, carrying people and going uphill, please use the foot pedal to help, and try to avoid instantaneous high current discharge. High-current discharge can easily lead to lead sulfate crystals, which can damage the physical properties of the battery pole plate.

Four, the correct grasp of charging time
In the process of use, you should accurately grasp the charging time according to the actual situation, with reference to the usual frequency of use and mileage, but also pay attention to the battery manufacturer to provide the capacity size instructions, as well as the performance of the supporting charger, charging times. In general the battery is charged at night, the average charging time is about 8 hours.
If it is shallow discharge (charging after driving mileage is very short), the battery will soon be full, continue charging will appear overcharge phenomenon, resulting in battery water loss, heat, reduce battery life. Therefore, the battery is best charged once when the depth of discharge is 60%-70%, and the actual use can be converted into riding mileage and charged as necessary according to the actual situation to avoid injurious charging.
Five, what matters should I pay attention to when using electric car in summer?
1) Avoid exposure to the hot sun and strictly forbid charging in a hot environment.
2) Avoid charging immediately after driving in high temperature and prevent charging for too long (about 8 hours normally).
3) battery charging when the power box is hot or does not turn green, should promptly to the battery business store or the company's after-sales service network, the battery or charger for testing and maintenance.
Six, avoid the plug heating when charging
Loose charger output plug, contact surface oxidation and other phenomena can lead to charging plug heating, heating for too long will lead to charging plug short circuit, direct damage to the charger, bringing unnecessary losses. Therefore, when the above situation is found, the oxide should be removed or replaced in a timely manner
Seven, when is the best time to charge the electric car battery?
When the power indicator on the electric car is at or near the lowest position, it is the best time to charge the electric car, which is beneficial to the service life of the battery. If the daily riding mileage is within 5-10km, it is recommended that you do not charge, that is to say, do not short mileage and charge diligently. Otherwise, it will cause the battery life to be terminated early.
Eight, can the charger be carried with the car?
No, the electric car often vibrates during use due to uneven road surface, if the charger vibrates, its component parameters will drift, affecting the charging performance and even damaging the battery (undercharge or charging drum battery), therefore, the charger is strictly prohibited to carry with the car.
