How to properly maintain battery of pure electric vehicle?

With the continuous enhancement of people's awareness of environmental protection, electric vehicles have gradually entered the public's vision and become the choice of many consumers.ou can only do diligent maintenance to extend the life of electric vehicles.

1. Grasp the charging time correctly.

In the use of electric vehicles, the charging time should be accurately grasped according to the actual situation, and the charging frequency should be grasped according to the usual use frequency and driving distance.

When driving normally, if the electric meter indicates the red light and yellow light, it should be charged; If only the red light is on, stop running and charge the battery as soon as possible, otherwise excessive discharge of the battery will seriously shorten its life.

After full charge running time is short charge, charging time should not be too long, otherwise it will form overcharge, make the battery heat. Overcharging and undercharging all shorten the battery life.

In general, the average charging time of a battery is about 10 hours. Stop charging if the battery temperature exceeds 65℃.

2. The storage battery is strictly prohibited from being in the state of power loss.

Loss state means that the battery is not charged in time after use.

When the battery is stored in the state of loss of electricity, it is easy to appear salinization , and the lead sulfate crystal attached to the plate will block the electric ion channel, resulting in insufficient charge and reduced battery capacity.

The longer the idle time, the more serious the battery damage.

Therefore, when the battery is idle, it should be replenished once a month to keep the battery healthy.

3. try to avoid stepping on the acceleration.

In the process of use, if the mileage of the electric vehicle suddenly drops by more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has a problem.

When electric vehicles start, carry people and go uphill, try to avoid stepping on the acceleration, resulting in instantaneous large current discharge.

High current discharge can easily lead to lead sulfate crystallization, which damages the physical properties of battery plate.

4. It is strictly prohibited to stay in the sun for a long time.

The high temperature environment will increase the internal pressure of the battery and cause the battery to lose water, causing the battery activity to decline and accelerating the plate aging.

5. Detection and treatment of common battery failures

In the case that the engine cannot start due to the lack of battery power or damage, the power supply on other vehicles can be used to start in parallel. The specific methods are as follows:

First, a jumper wire is used to connect the positive terminals of the two batteries.

Secondly, another jumper wire is respectively connected to the negative terminal of the battery of the power supply car and the negative terminal or the negative terminal of the battery of the losing trolley.

Thirdly, adjust the position of the wire so that it does not interfere with the moving parts of the engine compartment, such as the engine tape; The vehicle providing power should start first, and then start the vehicle with power loss after 1min.

After starting, the engines of the two vehicles are idled for about 3 minutes, during which time the wires should still be connected.

Finally, remove the wire in the opposite order to the connection order. At this time, the engine of the vehicle providing the power supply can be turned off, but do not turn off the engine of the losing trolley car.
