How long is the warranty of electric car battery?

The rules are calculated by buying a car for a total of 15 months. For psychological balance, I suggest you accept it, because the unpaid sale of the battery is indeed a total of 15 months. But in fact, even if you are 16 months old, you can try to communicate, euphemistically, I believe that everyone will not be so ruthless. There is no need to argue about this matter at the moment. In fact, your battery still has 15 months. However, after a total of 15 months, the store has the right to charge the relevant working hours and logistics transportation costs, etc., because the car is guaranteed for 15 months, which is a total of 15 months, and can be replaced N times.

Actually determine the service life of the electric vehicle, except for the motor, followed by the battery; the general motor has quality assurance, normal use; but if the battery. Generally, the number of recharged and refurbished batteries is about 50 times, so you will be warned to buy it for three months or half a year. No matter which brand of electric vehicle battery is guaranteed for one year, the battery problems in this year are free to replace. . You can go to the dealer to check the battery. If there is a problem with the battery, you can replace it for free, but only if it can be replaced free of charge within one year. . If the appearance or the column is damaged, you can only pay for it yourself! This depends on how bad your battery is! Or see how you are damaged! If it is direct damage, it is not covered by the warranty.

Electric car batteries are not used for life, so how long does the electric car battery warranty last? The life of a battery is generally 2-3 years. It is used by different people. Its battery life is different. It depends on how to maintain the battery. If you follow the normal practice, your battery life will exceed 2 years. Now let’s organize the maintenance methods for several electric vehicle batteries, so that everyone can use electric vehicles correctly and safely, and use them properly to extend battery life.

1. When the electric vehicle is on the bridge, climbing the slope or driving in the top wind, it should be supplemented by human power to prevent the battery supply current from abruptly increasing.

2. When you are riding on the bus or driving on the way to stop the emergency braking, it is best to use a few pedals, and then the electric car has a certain speed and then electric riding. Try not to use the electric vehicle to start the power directly at rest.

3. During cycling, try to avoid frequent braking and starting, and use the ankle to drive when the road is crowded. This not only increases the "continuation mileage", but also improves the battery efficiency, which also extends the battery life.

4. Frequent charging, so that the battery is often full, but you must grasp the total amount of charging time.

5. If it is not used for a long time, it should be stored after the battery is fully charged and recharged regularly (1 month).

How long does the electric vehicle battery warranty become more and more a concern for everyone? The electric car pays more attention to the above details in use, which can extend the service life of the electric vehicle battery.

The electric vehicle battery is generally a lead-acid battery. The battery manufacturer's warranty period for the dealer is generally 15 months, the first 8 after 7, due to the quality of the battery itself, the replacement battery within 8 months, 9 to 11 months for turnover Battery, 12 to 15 months for maintenance battery. At present, the shelf life of users in the secondary market is generally one year. This is because there is a certain period from the factory to the distribution office to the repair shop.

In 8 months, quality problems can be replaced. If the appearance of the battery is damaged due to human factors, including the battery bulging after detecting non-battery quality problems, it can only be downgraded to a turnover battery.

1 The charger parameter mismatch causes the thermal runaway during charging to cause the battery to swell, which is a human cause.

2 The quality problem of the internal pole group itself, such as the micro-short circuit of the extreme group and the lack of acid, will also cause the battery to run out of control and bulge. This is the quality problem of the battery itself.

Check whether the charger parameter is a problem. You can charge the battery with a matching charger after the battery is discharged. Observe and monitor the surface temperature of the battery. If the temperature is not abnormally high until it is hot (slightly hot is normal), you can conclude It is not an internal problem of the battery pole group, but it is caused by a mismatch of the charger parameters, and it is a human cause, and vice versa is the quality problem of the battery itself.

The general electric vehicle manufacturer and battery manufacturer's commitment is that the battery pack is used for one year, and the individual promises are for one and a half or two years. However, this package means that you only need to change the battery you can use when you change the battery, instead of replacing the battery, usually the battery after repair, the time that can be used is not very long.

Nationwide warranty does not mean that you can go to a store to change batteries for free. You can only go to the store designated by the manufacturer to change.

When changing the battery, the store is replacing a group of batteries together. Of course, you can also ask the store to change only one section, but the other batteries must be good, and the battery should be replaced with the battery performance. Close, this will ensure that you can use the battery for a longer period of time

Your battery is definitely broken, the charger is not good, it is hard to say, use it after changing the battery.
