With the society's attention to air and the continuous innovation and maturity of new energy vehicle technology, consumers' acceptance is rising, and the sales of new energy vehicles are growing rapidly. Like traditional cars, new energy vehicles also need care! Next, let's take a look at the tips for the maintenance of new energy vehicles.
Knowledge 1: Avoid large current discharge.
When the electric car starts, carries people and goes uphill, try to avoid stepping on the acceleration and forming instantaneous high current discharge. High current discharge easily leads to crystallization of lead sulfate and damages the physical properties of battery plates.
Knowledge 2: avoid plug heating when charging.
220 volt power plug or charger output plug loose, contact surface oxidation and other phenomena will lead to plug heating, heating for too long will lead to plug short circuit or poor contact, damage the charger and battery, and bring you unnecessary losses. Therefore, when the above situation is found, the oxide should be removed in time or the connector should be replaced.
Knowledge 3: It is forbidden to cut off power when storing.
When the battery is stored, it is strictly prohibited to be in a state of power loss. The state of insufficient power means that the battery is not charged in time after use. When the battery is stored in a state of insufficient electricity, it is easy to be sulfated, and the lead sulfate crystal adheres to the electrode plate, which will block the ion channel, lead to insufficient charging and decrease the battery capacity. The longer the battery is idle, the more serious the battery damage is. Therefore, when the battery is idle, charging it once a month can better keep the battery healthy.
Knowledge 4: prevent exposure to the sun
Electric cars are strictly forbidden to be exposed to the sun. High temperature environment will increase the internal pressure of the battery, make the battery lose water, lead to the decline of battery activity and accelerate the aging of the pole piece.
Knowledge 5: Grasp the charging time correctly.
In the process of use, we should accurately grasp the charging time according to the actual situation, and grasp the charging frequency with reference to the usual use frequency and mileage. When driving normally, if the meter indicates that the red light and yellow light are on, it should be charged; If only the red light is on, stop running and charge as soon as possible, otherwise the battery's excessive discharge will seriously shorten its life. After fully charged, charge the battery for a short time, and the charging time should not be too long, otherwise it will be overcharged and the battery will heat up. Overcharging, overdischarge and undercharge will shorten the battery life. In general, the average charging time of a battery is about 10 hour. If the battery temperature exceeds 65℃ during charging, please stop charging.
Knowledge 6: Regular inspection
In the process of use, if the continuous mileage of electric vehicles 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. At this time, you should go to the sales center or the maintenance department of the agent in time for inspection, repair or matching. This can relatively extend the life of the battery pack and save your expenses to the greatest extent.
Knowledge 7: Always check the tire pressure.
In order to maintain the correct tire pressure, tire pressure must be checked every two weeks or at least once a month. Incorrect tire pressure will cause power consumption, short driving mileage, reduce driving comfort, reduce tire life and reduce driving safety.
Knowledge 8: Other Important Precautions
1, check whether the power is sufficient, whether the braking performance is good, whether the screws are loose, etc. Before leaving the car every day. If there is any fault, it should be repaired and eliminated in time. Only after the inspection is completed and it is determined that there is no fault can the car leave.
2. When repairing or replacing the charging fuse of the charging part, the plug of the 220V power supply must be unplugged first, and live operation is not allowed.
3. Turn off the power switch every time you stop, pull out the key, turn the gear switch to neutral and pull the handbrake.
4, maintenance or replacement of batteries, electrical appliances, must turn off the power switch after operation.
5. Children should turn off the key switch when playing in the car to avoid danger.
6. Before driving the electric car, check whether the door is closed.
7. Charging should be carried out where children can't reach.
8. In case of fire caused by accident or other reasons, turn off the main power switch immediately.
