Electric vehicles have gradually entered the life of the public and become more and more consumers' car buying choices. But do you know, although electric vehicles bring more convenience to people's lives, the maintenance of electric vehicles can not be ignored at the same time, only to do their frequent maintenance, can prolong the service life of electric vehicles.

1. Correctly grasp the charging time

In the process of using 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 usage frequency and driving range. When driving normally, if the electric meter indicates red light and yellow light, it should be charged; if only the red light is left, it should stop running and charge as soon as possible, otherwise the battery's excessive discharge will seriously shorten its life. Full charge running time is short on charging, charging time should not be too long, otherwise it will form excessive charging, so that the battery heating. Over charging, over discharging and under charging can shorten battery life. In general, the average charging time of the battery is about 10 hours. If the battery temperature exceeds 65 ° C, stop charging.

2. Storage battery is strictly prohibited in the state of power deficit

Deficit state means that the battery is not charged in time after use. In the deficit state of storage battery, it is easy to appear sulfate, lead sulfate crystal attached to the plate, will block the electrical ion channel, resulting in insufficient charging, battery capacity decline. The longer the idle time in the deficit state, the more serious the battery damage. Therefore, when the battery is idle, replenish it once a month to keep the battery healthy.

3. Try to prevent hard pedaling

In the process of use, if the range of an electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has a problem. Electric vehicles in the start, manned, uphill, as far as possible to prevent sharp acceleration, the formation of instantaneous high current discharge. High current discharge may lead to lead sulfate crystallization, which damages the physical properties of the battery plate.

4. Do not expose yourself to the sun for a long time

The environment with too high temperature will increase the internal pressure of the battery and make the battery lose water, cause the battery activity to decline, and accelerate the aging of the plate.

5. Detect and handle common battery faults

In the daily use of the vehicle, you may encounter the situation that the engine cannot start due to insufficient battery power or damage. In this case, you can use the power supply of other vehicles to start in parallel. The specific practices are as follows:

Firstly, a jumper wire is used to connect the two positive terminals of the battery respectively.

Secondly, another jumper wire is connected to the negative electrode of the power supply car battery and the negative electrode of the battery of the electric car or the negative wire;

Third, adjust the position of the wires so that they do not interfere with the moving parts of the engine compartment, such as the engine tape; The vehicle with power supply should be started first, and then the vehicle with power deficit should be started 1min later. After starting, the engine of the two cars should be idling for about 3 minutes, during which time the wires should still be connected;

Finally, the order of wire removal is opposite to the connection order. At this time, the engine of the power supply vehicle can be turned off, but do not turn off the engine of the deficit trolley car.
