How to maintain the electric car battery

Date:Apr 23, 2019

I believe that many people have a lot of love for their electric cars, and they are often cleaned and maintained, but if you know a little about common sense, you can basically get it without running the repair shop.

1. Does the newly purchased electric car need to charge the lithium battery before use?

need. The lithium battery has a turnover process from the factory to the loading and then to your hand. During the turnover period, the lithium battery will have insufficient capacity due to self-discharge, so the lithium battery must be charged with the on-board charger until it is sufficient.

2. If the long-term business trip is outside, what should be done when the electric car is not in use?

The battery must be fully charged and stored, and the battery must be recharged once a month to avoid the battery being degraded due to long-term deficient storage, resulting in a decrease in capacity or even scrap.

3. What should I pay attention to when using electric vehicles in summer?

1) Avoid exposure to high temperature and strong sun, and it is strictly forbidden to charge in high temperature environment;

2) Avoid charging immediately after driving at high temperature to prevent charging time from being too long (normal 8 hours or so);

3) When the battery is charged, the power box is hot or does not turn green. It should be in time to the battery store or our after-sales service network to test and maintain the battery or charger.

4. What will happen to the use of electric vehicles in winter, how should we avoid them?

When you use an electric car in winter, you will feel a significant drop in the mileage (more obvious in the north), which is normal. Since the charge acceptance of a battery is lowered in a low-humidity environment, the viscosity of the electrolyte increases, and the resistance of the electrochemical reaction increases, resulting in a decrease in the battery capacity. Therefore, consumers should avoid placing the electric car outdoors or charging it in a low temperature environment during winter use.

5. What should you pay attention to when riding an electric car?

In order to extend the service life of your electric vehicle, it is recommended that you start slowly at a constant speed when driving the electric vehicle, and then use electric power to ride; the load should not be excessive when riding (no more than 75kg according to regulations); if there is a steep slope during riding Or the wind should be assisted by the ankle. All of the above measures are to prevent the battery from affecting the service life due to large current discharge.

6. Can an electric car continue to ride if there is insufficient power when riding?

No, you should charge in time when the battery is low. Although the battery has a controller with voltage limit protection, but the static moment, the storage point voltage rises, and can be briefly riding, so the use of the battery damage the most, will cause the battery to over discharge, seriously affecting the service life.

7. What harm does the battery of the electric vehicle have when it is overcharged?

If you use a poor quality charger or charger failure or you charge the battery for too long, it will cause the battery to lose weight, the electrolyte will dry out too early, it will easily cause the drum to deform, so the battery life will be terminated early.

8. What are the safety precautions when using the battery?

1) The battery should not be close to the open flame or high temperature heat source. The battery should not be thrown into the fire or immersed in the water. It is strictly prohibited to directly expose or charge in the sunlight.

2) The battery should not be placed in a closed container and should be well ventilated.

3) If the battery case is found to be broken or leaking, the battery must be replaced.

4) The electrolyte is an acidic solution. If it is on the skin or clothing, it should be rinsed with plenty of water immediately. If it is serious, it must be sent to hospital for treatment.

5) The battery must not be short-circuited and must not be used upside down.

9. When is the best charge for electric vehicle batteries?

When the electric energy display indicator on the electric vehicle is at the lowest or near minimum position, charging the electric vehicle is optimal, 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, do not charge for a short distance. Failure to do so will result in early termination of battery life.

10. Can the charger be carried with the car?

No, the electric vehicle often vibrates due to uneven road surface during use. If the charger vibrates, its component parameters will drift, affecting the charging performance or even damaging the battery (filling the battery or charging the battery). Therefore, the charger is strictly prohibited. Carrying the car.
