For the car owners, they will definitely do car maintenance on a regular basis, but because new energy vehicles are not listed on the market for a long time, and new energy vehicles generally have batteries. So there are quite a few friends who ask if new energy vehicles need maintenance? Of course, it is to be maintained! As long as the car is definitely to be maintained, just like ours, whether it is children or the elderly, we must pay attention to health. Today, Movable Car Lift will introduce you to the battery maintenance of new energy vehicles.
Do new energy vehicles need maintenance? Maintenance methods
First, avoid large current discharge
When the electric car starts, carries people, and goes uphill, try to avoid slamming and accelerating, forming an instantaneous large current discharge. Large current discharges tend to cause the formation of lead sulfate crystals, which impair the physical properties of the battery plates.
Second, avoid plugging when charging
The 220 volt power plug or charger output plug is loose, the contact surface is oxidized, etc., which will cause the plug to heat up. If the heating time is too long, the plug will be short-circuited or contact poorly, which will damage the charger and the battery and cause unnecessary loss. Therefore, when the above situation is found, the oxide should be removed or the connector replaced.
Third, it is strictly forbidden to lose electricity when stored
The battery must not be in a deficient state when it is stored. The deficient state means that the battery is not charged in time after use. When the battery is stored in a depleted state, it is prone to sulfation, and the lead sulfate crystals adhere to the plate.
On, will block
The ion channel causes insufficient charging and the battery capacity decreases. The longer the idle state is idle, the more severe the battery is damaged. Therefore, when the battery is not in use, it should be replenished once a month, which can better maintain the health of the battery.
Fourth, prevent exposure
Electric vehicles are strictly prohibited from exposure to sunlight. Excessive temperature environment will increase the internal pressure of the battery and cause the battery to lose water, causing the battery activity to decrease and accelerate the aging of the plate.
Fifth, correctly master the charging time
In the process of use, you should accurately grasp the charging time according to the actual situation, and refer to the usual use frequency and mileage to grasp the charging frequency. During normal driving, if the electricity meter indicates that the red and yellow lights are on,
Should be charged
If only the red light is left, stop running and charge as soon as possible, otherwise the battery will be over-discharged, which will seriously shorten its life. Charging after a short running time, the charging time should not be too long, otherwise it will form an overcharge, so that
The battery is hot. Overcharging, overdischarging, and undercharging can shorten battery life. In general, the average charging time of the battery is about 10 hours. Charging process, such as battery temperature exceeds 65 ° C, should stop charging.
Six, regular inspection
In the course of use, if the mileage of the electric vehicle suddenly drops by a dozen kilometers in a short time, it is very likely that there is at least one battery in the battery pack. At this time, you should go to the Auto Superman professional maintenance platform for inspection, repair or matching. This will extend the life of the battery pack and save you money.
Seven, often check the tire pressure
To maintain the tire pressure at the correct tire pressure, the tire pressure must be checked every two weeks or at least monthly. Incorrect tire pressure can result in low power consumption, short driving distance, reduced driving comfort, reduced tire life and reduced driving safety.
Eight other important attention items
1. Check whether the power is sufficient before the vehicle is out, whether the braking performance is good, whether the screws are loose, etc. If there is any fault, it should be repaired and eliminated in time. If the inspection is completed, it is determined that there is no fault before exiting.
2. When charging or repairing the charging fuse, you must first unplug the 220V power plug and do not work with power.
3. Each time you stop, you must turn off the power switch, pull out the key, pull the gear switch to the neutral position, and pull the hand brake.
4, repair or replace the battery, electrical appliances, must be turned off after the main switch.
5. When the child is playing in the car, remove the key switch to avoid danger.
Does new energy vehicles need maintenance? The difference between new energy vehicles and fuel vehicles
The fuel car is mainly for the maintenance of the engine system, while regularly changing the oil, machine filter and so on. New energy vehicles are driven by motors, which naturally omit conventional maintenance items such as oil, three filters, belts, etc., and only need to maintain the battery pack and motor to keep it clean. As can be seen from the difference between the conventional maintenance items, the maintenance of new energy vehicles is easier than the fuel vehicles.
1. Before driving the electric vehicle, check that the door is closed.
2. Charging should be carried out in a place that children cannot reach.
3. Turn off the main power switch immediately when there is a fire due to an accident or other reasons.
Do new energy vehicles need maintenance?
This part of the battery needs to be talked about separately. It is the source of all power and the most special and important part of electric vehicles. There is no such thing as the details that need to be paid attention to in maintenance.
1. How to correctly master the charging time?
When the red and yellow lights of the fuel gauge indicator light up, it indicates that the charging is performed; when the red light is on, stop the operation immediately and charge as soon as possible, otherwise the battery will be over-discharged and the life will be shortened seriously. When the battery is fully charged, the charging time is short, and the charging time should not be too long. Otherwise, overcharging, battery heating, and battery life will be shortened. In general, the average charging time of the battery is about 8-10 hours. If the battery temperature exceeds 65 °C during charging, stop charging immediately.
According to the actual situation, accurately grasp the charging time, refer to the usual use frequency and driving mileage, and grasp the charging frequency.
2. How to protect the charger?
Keep the charger ventilated while charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the state of charge.
3. What is “regular deep discharge”?
The battery is periodically subjected to a deep discharge, which is beneficial to activate the battery properties and slightly increase the battery capacity.
4. How to avoid the plug heating when charging?
The cause of the plug heating may be that the 220 volt power plug is loose, the charger output plug is loose, or the contact surface is oxidized. If the heating time is too long, the plug may be short-circuited or poorly contacted, directly damaging the charger and the battery. Therefore, once the above conditions are found, the oxide should be removed or the connector replaced.
5. Why do you have to charge every day?
Most chargers charge about 97% to 99% after the indicator light is fully charged. Although the difference of 1% to 3% of the power has almost no effect on the continuation capability, it will form an undercharge accumulation. So when the battery indicator shows that the battery is full, try to charge it for a while. And charging every day can make the battery in a shallow cycle, which is beneficial to extend battery life.
6. Why is the battery strictly prohibited from being in a deficient state when it is stored?
The state of deficient power means that the battery is not charged in time after use. When the battery is stored in a deficient state, sulphation and lead sulfate crystals are likely to adhere to the electrode plate, which may block the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle state is idle, the more severe the battery is damaged. Therefore, even if the battery is not used, it should be charged once a month, so that the battery can be kept healthy.
7. How to avoid large current discharge?
When the electric vehicle starts, manned, or goes uphill, try to avoid stepping on the accelerator to accelerate. Instantly, large current discharge will produce lead sulfate crystals, which will damage the physical properties of the battery plates.
8. What should I pay attention to when cleaning an electric car?
During the cleaning process, care should be taken to prevent water from flowing into the charging socket of the vehicle body, resulting in short circuit of the body line.
