Electric vehicle battery use and maintenance need to know
With the promotion of new energy vehicles, electric vehicles have increasingly become the darling of consumers. Especially after Tesla's fire has burned China, how do we maintain our cars? The following small series to tell you!
First, maintenance should pay attention to the problem
1, the maintenance of electric vehicle batteries should also be maintained in time
When the battery has the following conditions need to be maintained
(1) Long-term charge does not change green light
(2) The battery is hot when charging
(3) Battery capacity drops too fast
2, regular maintenance of electric vehicle battery maintenance
During use, if the mileage of the electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one of the batteries in the battery pack has a short circuit, such as a broken cell, soft plate, and active material shedding. . At this point, inspection, regeneration, and matching should be conducted in a timely manner. This can relatively extend the life of the battery pack and maximize savings.
3, also pay attention to the battery maintenance of electric vehicles: The battery should be firmly installed on the electric bicycle to prevent the battery from being damaged by the vibration during riding; often remove the dust and dirt on the battery cover, pay attention to keep the battery dry and clean. Prevent the battery from discharging itself.
Second, how to extend battery life
Electric vehicle batteries need to be renewed in the past year and a half. How can we extend the battery life of electric vehicles?
1, can not overload the first heavy-duty driving (such as riding with people or loading heavy objects, etc.), found that when the meter shows that the battery is running low, it is necessary to use human riding, because the deep discharge of the battery life loss.
2, pay attention to charging method. When the new battery is charged for the first time, the time must be long, and it is necessary to ensure sufficient electricity. For lead-acid batteries, no matter how far away they are, they must be recharged immediately after use. When they are charged, they should not be fully depleted before they think of charging. If the car is not used for a long time, it is necessary to ensure that it is replenished once a month. This will both protect the battery and extend its useful life.
3. Try to avoid sudden braking. Frequent emergency braking will affect the brake comfort, consume battery capacity; the speed should not be too fast, the faster the speed, the greater the loss of the battery.
4, do not use the motor to start the car directly in a static state, it is best to start with the foot and help. When using the bridge, uphill, or against the wind, you must use pedal power to avoid impact damage to the battery and affect the battery's continued mileage and service life.
Third, the daily maintenance of electric vehicle battery knowledge
1. Check the battery, shell cover and seal of the electric vehicle battery. There should be no cracks.
2. Check the battery installation must be secure. Wires and column poles must be firmly connected
3. Scrub the outside of the battery with hot water and wipe dry. Clean the surface of the battery with dust or mud with a cleaning cloth or cotton yarn, wipe off the electrolyte on the battery cover, keep the battery and connection leads clean and dry.
4. Check the poles. There should be no loosening. Remove oxide from poles and wire connectors. It is forbidden to enter the battery with debris or other debris.
5 Check the starting cable and replace it if it is damaged.
6. Do not tap the battery. This is because the lead plate in the battery is extremely low and very fragile. It cannot be knocked because the battery is not functioning properly, causing the shell to break and the plate to be damaged.
