What problems should be paid attention to when using new energy vehicles?

Ac charging pile

AC charging pile is a power supply device that is fixedly installed in community parking lots, residential quarters, large shopping malls, service areas, roadside parking lots and other places, and is connected to the power grid to provide controllable unidirectional AC power supply or three-phase AC power supply for electric vehicle charger.

The AC charging pile itself has no charging function, it only provides power output, and it needs to be connected to the on-board charger of the electric vehicle to charge the battery of the electric vehicle. Because the power of on-board charger of electric vehicle is generally small, AC charging pile can not realize fast charging.

Dc charging pile

DC charging pile is also a kind of outdoor charging equipment, such as community parking lots, residential quarters, large shopping malls, service areas, roadside parking lots, special electric vehicle charging stations and so on. And connected to the power grid to provide DC power for electric vehicle batteries.

Because DC charging pile can directly charge the battery of electric vehicle, it generally adopts three-phase four-wire system or three-phase three-wire system for power supply, and the output voltage and current can be adjusted in a wide range, so it can realize the rapid charging of electric vehicle.

Maintenance and use skills of new energy vehicles

Avoid large current discharge

When the electric car starts, carries people and goes uphill, try to avoid sudden acceleration and form instantaneous high current discharge. High current discharge easily leads to crystallization of lead sulfate and damages the physical properties of battery plates.

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 time will lead to plug short circuit or poor contact, damage the charger and battery, and bring unnecessary losses. Therefore, when the above situation is found, the oxide should be removed in time or the connector should be replaced.

Power failure is prohibited during storage.

When storing the battery, it is strictly prohibited to be in the power-off state. 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 power, it is easy to be sulfated and attached, which will block the ion channel, leading to insufficient charging and battery capacity decline. The longer the battery is idle, the more serious the battery damage is. Therefore, when the battery is idle, it should be charged once a month, which can better keep the battery healthy.

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.

Correctly grasp the charging time

In the process of use, the charging time should be accurately grasped according to the actual situation, and the charging frequency should be grasped 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, please stop running and charge it as soon as possible, otherwise the excessive discharge of the battery will seriously shorten its life.

After being fully charged, charge the battery for a short time, not too long, otherwise it will be overcharged and the battery will heat up. Overcharging, overdischarge and undercharge will shorten the battery life. Generally speaking, the average charging time of a battery is about 10 hour. If the battery temperature exceeds 65℃ during charging, please stop charging.

Periodic 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 likely that at least one battery in the battery pack has a problem. At this time, you should go to the sales center or maintenance department of the agent in time for inspection, repair or matching. This can relatively extend the life of the battery pack and save money to the greatest extent.

Check the tire pressure frequently.

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.

This concludes the introduction of the use of new energy vehicles. The most important and noteworthy part of an electric vehicle is the battery, because the battery is the core of the whole vehicle. Whether in use, charging and maintenance, we should pay more attention to the battery maintenance of pure electric vehicles mentioned above, and the correct use of electric vehicles can be safe and environmentally friendly.
