It is not good for electric car to change battery once the car can't run far away.

The electric car has not been running for a long time. People think that it is the problem of the battery. The problem is that the electric car has not been used for a long time and it is not far away. Is it also a battery problem? In fact, it is not entirely true. There are many reasons why electric vehicles can't run far, but many users don't know the existence of these problems, they feel that the battery is causing trouble, and the battery is replaced by one hundred.

First of all, the electric car is not far away. You can let the maintenance master check if the battery is normal. If it is not far from normal, it is the following reasons:

1. Insufficient motor power leads to wasted power

Nowadays, low-priced electric vehicles are flooding the market. Some users are greedy for some cheap, and they have bought low prices. The equipment is likely to be refurbished. Refurbished motors have high magnet content, high power loss, low tank fullness, and are prone to rust. These reasons can cause motor power shortage. On the other hand, if the refurbished motor is made of recyclable recycled aluminum, the low-purity recycled aluminum will also cause the motor to heat up and increase the power loss.

2. The charger improperly damages the battery

The general brand-name charger, the quality of the circuit board and internal electronic components used, will make the voltage higher or lower, which will easily damage the battery and further affect the mileage of the electric vehicle.

3. Inferior controller damage battery

The controller itself has a controlling effect on the battery. Inferior controllers, whether it is workmanship or control panels are very rough, parameters are not accurate, it is easy to cause large current, damage the battery, easy to shorten the battery life, thus affecting the mileage of electric vehicles.

4. Should be powered off when braking

If the acceleration speed is not returned to the brakes, the electric car will run with the brakes, and the phenomenon of “top cow” that rotates while rotating, not only will cause the brakes to be ineffective, but also cause the whole vehicle parts to “fatigue work”. ", will also waste power, if there is no brake power off, then go to the master to repair it.

5. Overloading exceeds the standard, resulting in large current discharge

Generally in towns and villages, overloading is a common problem. Many users use electric vehicles as trucks. It is not necessary to transport everything away at one time. At this time, electric vehicles not only run fast, but all components are forced to run and cause current discharge large, further affecting the battery and shortening the life.

6. Tire pressure affects electricity

Tire pressure and the battery seem to have nothing to do with, but in fact, too low pressure will consume too much power. Generally suitable tire pressure should be 310-380kpa.

So in summary, the battery is easily damaged and consumes a lot of power. It is not necessarily a problem of the battery itself. Most of them are problems of inferior parts, and there are details in the process of use. Therefore, if you want the car to be used for a longer period of time, on the one hand, it is not cheap to buy inferior cars, after all, the cost of maintenance is also large; on the other hand, it must be standardized, so that not only the battery life will be extended, electric vehicles Other problems will appear less.
