How to maintain the electric vehicles?

How to maintain the electric vehicle? 

Appearance: that is, the appearance of the vehicle is inspected, the main appearance checks are whether the function of the lights is normal, the aging condition of the wiper tape, whether the paint is damaged, etc.

Tires: Because the tires are equivalent to the shoes people wear, they are in direct contact with the ground. Due to the factors of road conditions, there will be a variety of failure phenomenon. Mainly for tire pressure, cracks, trauma and wear and tear, etc.

Chassis: also as usual, mainly for each transmission parts, suspension and chassis connections to see if loose aging.

Fluid: antifreeze, unlike fuel cars, electric car antifreeze is used to cool the motor and needs to be replaced regularly according to the time specified by the manufacturer (the general replacement cycle is 2 years or 40,000 km). In addition, gear oil, also called transmission fluid, is also a fluid that needs to be replaced more frequently in electric cars.

Cabin: Check the wiring harnesses in the cabin for aging and false connections. Remember, do not use water to clean the inside of the cabin.

Battery: As the power source of electric vehicles, battery is the most special and important part of electric vehicles.

When the power meter warning light is on, the vehicle needs to be charged, otherwise it will lead to over discharge of the battery to seriously shorten its life. Charging after a short running time after a full charge, the charging time should not be too long, otherwise it will form overcharge and battery heating, which will also shorten the battery life. The average charging time of the battery in general is about 8-10 hours. If the temperature of the battery exceeds 65℃ during the charging process, stop charging immediately.

When to charge the electric vehicles?

1. In order to ensure the battery life and charging state, you need to maintain a ventilated state when charging, to avoid heating the plug when charging, causing the plug to heat up roughly due to plug loosening or contact surface oxidation. Heating for too long will lead to plug short circuit or poor contact, direct damage to the charger and battery.

2. for regular deep discharge, the battery regularly a deep discharge, conducive to activating the battery properties, but also slightly enhance the battery capacity. When the battery indicator shows that the electricity is full, as far as possible, let the tower and then charge a little longer. And every day if you charge, can make the battery in a shallow cycle state, conducive to extending the battery life.

3. If the vehicle is not used for a long time, it is strictly prohibited to be in a state of power loss when stored, because the battery in a state of power loss is prone to sulfation, lead sulfate crystals attached to the pole plate, will block the electric ion channel, resulting in insufficient charging, battery capacity decline. The longer the battery is idle, the heavier the damage to the battery. Therefore, even if the battery is idle, it should be charged once a month to keep the battery in a healthy state.

4. Avoid high current discharge, electric car in the start, carrying people, uphill should try to avoid accelerating the throttle. Because instant high current discharge will produce lead sulfate crystals, which will damage the physical properties of the battery plates.

5. If the electric car in the process of use, found that the range in a short period of time, a sudden substantial drop of more than ten kilometers, it is very likely that at least one battery in the battery pack has a problem, should be promptly to the 4S pad for inspection, repair or matching group.

Maintenance notes:

1. What is the ambient temperature for vehicle charging?

The ambient temperature range for vehicle charging is 0℃~45℃, when the ambient temperature is lower than 0℃ or higher than 45℃, try not to charge the vehicle.

2. Do I need to charge immediately after parking? 

Make the habit of charging in time after using the vehicle. In winter, due to the low ambient temperature, it is recommended to charge the vehicle immediately after parking.

3. How should I store the power battery?

As a power source, the best charging environment temperature is 25℃.

4. Should the charging time be extended in winter?

The power battery has poor charging capacity, which can easily cause undercharge and power shortage, so the charging time of the power battery needs to be extended.

5. What do I need to pay attention to when using the car in winter?

Electric car range will generally be affected, the power will be reduced, the range of decline is generally 10% ~ 20%, this is a normal phenomenon, when using the vehicle pay attention to the driving range of the day.

6. Do I need to completely empty the battery when I use the car?

When the electric car is used again, it is not possible to completely empty the electricity, and it is recommended to have more than 20% of the electricity left when driving each time.

7. How to maintain the battery when the vehicle is not in use for a long time?

Ensure that the remaining power of the vehicle is greater than 30%, it is recommended to replenish the electricity once a month when the ambient temperature is greater than 5 ℃, in order to maintain the health of the battery.

8. What should I pay attention to when using the vehicle in winter?

In winter, the power performance of the vehicle is relatively poor, when the vehicle starts, carries people, and goes up the slope, try to avoid stepping on the acceleration, forming a large current discharge, which is not conducive to the health of the battery.

9. How do I need to take care of the charging interface?

The charging interface should be kept clean, not water or other has no excuse to enter the charger, because then it is easy to cause a short circuit inside the charging interface of pure electric vehicles, which has an impact on the service life of the battery.

10. What should I pay attention to when I go out in rainy and snowy weather?

Before going out, you should pay attention to check whether each new energy pure electric car accessories are good and whether the battery is sufficiently charged. In case of rain and snow, do not let the water flood the center of the wheel hub, so as to prolong the life of the battery and motor of the pure electric vehicle.
