How to maintain electric vehicle battery?

  1. Is it necessary to charge the electric vehicle battery before using the newly purchased electric vehicle?

need. There is a turnover process from the factory to the loading of the battery and then to your hands. During the turnover period, the capacity of the battery will be insufficient due to self-discharge. Therefore, the battery must be charged with the on-board charger until it is fully charged.

  1. If you are on a long-term business trip, what should you do with the battery when the electric vehicle is not in use?

The battery must be fully charged and stored, and the battery must be replenished once a month in the future to avoid the battery’s capacity decline due to the sulfation of the plate due to long-term power loss storage, or even scrapped.

  1. What should be paid attention to when using electric vehicles in summer?

1) Avoid exposure to the sun under high temperature and hot sun, and it is strictly forbidden to charge in a high temperature environment;

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

3) When the battery is charging, if the power box is hot or the green light does not turn, you should go to the battery store or our company’s after-sales service outlets in time to check and maintain the battery or charger.

  1. What will happen when using electric vehicles in winter, and how to avoid them as much as possible?

When using electric vehicles in winter, you will feel that the mileage of the continuation has dropped significantly (it is more obvious in the north), which is a normal phenomenon. Because in a low-humidity environment, the charge acceptance capacity of the battery is reduced, and the viscosity of the electrolyte increases, and the resistance of the electrochemical reaction increases, resulting in a decrease in the battery capacity. Therefore, consumers, you should avoid leaving the electric car outside overnight or charging it in a low temperature environment when using it in winter.see more:custom lithium battery

  1. What should be paid attention to when riding an electric vehicle?

In order to prolong the service life of your electric vehicle, it is recommended that you start slowly and move forward at a constant speed when starting the electric vehicle, and then use electric power to ride; the load should not be excessive when riding (no more than 75kg according to the regulations); if you encounter a steep slope during riding Or against the wind should pedal assist. The above measures are all to prevent the service life of the battery from being affected by high current discharge.

  1. If the battery is low when riding an electric vehicle, can I continue to ride?

No, you should charge it in time when the battery is low. Although the battery is protected by the voltage limiter of the controller, if it is still for a while, the voltage of the storage point rises, and the battery can be used for a short ride. Such use will cause the most damage to the battery, which will cause the battery to be over-discharged and seriously affect the service life.

  1. What is the harm to the battery when the electric vehicle battery is overcharged?

If you use a poor-quality charger or the charger is faulty or you charge the battery for too long, it will cause the battery to lose water and the electrolyte will dry up prematurely, which will easily cause the drum to be deformed, and the service life of the battery will be terminated in advance.

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

1) The battery should not be close to open flames or high-temperature heat sources, and the battery should not be thrown into fire or submerged in water, and it is strictly forbidden to expose or charge the battery directly in the sun.

2) Batteries should not be placed in airtight containers and should be well ventilated.

3) If the shell of the battery is found to be cracked or leaked, the battery must be replaced.

4) The electrolyte is an acidic solution. If it gets on the skin or clothes, it must be washed with plenty of water immediately, and it must be sent to the hospital for treatment in severe cases.

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

  1. When is the best time to charge the electric vehicle battery?

When the pointer of the power indicator on the electric vehicle is at or near the lowest position, it is best to charge the electric vehicle, 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 the mileage and charge frequently. Failure to do so will result in premature termination of battery life.see more:48v lithium ion battery 400ah

  1. Can the charger be carried with the car?

No, electric vehicles often vibrate due to uneven road surfaces during use. If the charger vibrates, the parameters of its components will drift, affecting charging performance and even damaging the battery (undercharged or fully charged). Car carry.
