Car Charging FAQ

With the gradual popularization of charging cars, the operation of car charging also needs us to be familiar with, and mastering the relevant charging knowledge can sometimes play a big role.

1. Can the air conditioner be turned on while charging?

Answer: Yes.
1. For some vehicles, the system needs to be turned off before charging, and the air conditioner can be used after starting the vehicle after charging.

turned off before charging

2. The new vehicle has no operation to turn off the system, and the air conditioner is not affected by charging and can be used all the time.

air conditioner is not affected

2. Does turning on the air conditioner during charging have any effect on the battery?

Answer: It has no effect on the battery, but has a little effect on the charging speed.
When charging, the air conditioner and the battery are in a parallel relationship. A small part of the power is used by the air conditioner, and most of the power is used for charging the battery:

Comparing the power distribution data in the above figure, it can be seen that during fast charging, turning on the air conditioner has little effect on the charging speed, while it has a greater impact on slow charging.

3. Can it be charged in rain or snow or during thunderstorms?

Answer: Yes.
1. There should be no water or foreign objects in the interface before inserting the gun. After inserting the gun, the interface is waterproof, and it is no problem to charge in rain and snow.

2. Charging stations, EV chargers, lines, cars, etc. all have lightning protection designs, and it is safe to charge in thunderstorms. To be safe,
At this time, please stay in a safer room.

It is also safe to charge during a thunderstorm

4. Can I sleep in the car while charging?

A: You can move in the car, but do not sleep in the car.

Limited by current battery technology, spontaneous combustion may still occur during charging. According to national standards, the battery will not catch fire or explode within 5 minutes after a thermal runaway occurs, so that the occupants in the car can leave in time. It is strongly recommended not to sleep in the car while charging!

More than 5 minutes

do not sleep in the car

5. How much power is left to charge?

A: It is best to keep the car battery between 20% and 80%.

1. If the power is lower than 20%, it should be charged. If there is a charging pile at home, it can be charged at any time. Slow charging every day has no effect on the battery.

2. The car is just a tool, even if it is needed, it will not have any visible impact even if the battery is turned on to 0.

6. How much power should be charged?

A: Slow charge does not affect, fast charge to 80%-90% is better.
1. It doesn’t matter how much you charge slowly, it’s best to charge it.
2. Fast charging is recommended to be 80%-90%. Some fast charging columns will automatically stop charging at about 95% to avoid overcharging.

3. The long-term low power will cause the battery to decay. If you do not drive for a long time (more than 3 months), please charge it 80% and park it. It is recommended to start the inspection once a month and charge the small battery by the way.

7. Can I pull out the gun without stopping charging?

A: No, please follow the following methods to draw a gun.

1. The fast charging gun comes with a lock, which will be locked when charging, and automatically unlocked when charging is stopped, and then the gun can be pulled out.

The quick charge gun will make a “pop” sound when it is locked and unlocked
hint:
In the public charging pile, if you see that some cars have stopped charging, you can use the gun directly.
Tesla can’t, the door must be unlocked at the same time to draw the gun.

2. The slow charging gun does not have a lock, but the slow charging interface of the body has a lock, which is generally locked or unlocked synchronously with the car, so the slow charging pile needs to unlock the door before pulling the gun.

3. When charging slowly, first unlock the car door, then press the switch of the slow charging gun to pause for a few seconds, the slow charging pile will also automatically power off, and the gun can be pulled out.

However, this operation is risky and may not be supported by some vehicles

4. In emergencies (such as electricity leakage) or special circumstances (such as failure of the charging column software and hardware to stop charging), you can press the red “emergency stop button” on the charging column, and then pull out the gun.

When the charging pile cannot be charged, you can also check whether the emergency stop button pops up. If you press the emergency stop under special circumstances, please restore it in time so that others can use the charging pile.

8. What should I do if the gun cannot be pulled out after stopping charging?

A: Repeat the operation several times first, and then unlock it manually.

1. When it is found that the gun cannot be pulled out, first operate it several times according to the normal process, such as pushing it in and pulling it out, restarting the charging and stopping it later, or repeatedly locking and unlocking the door, etc.

Manually unlock the charging gun

1. Find the unlocking holes at the positions indicated by the arrows and remove the plugs.

2. Note that some tips are equipped with special small keys or unlocking ropes
3. Use a screwdriver/small key/small stick to insert into the hole or pull the rope to unlock.

3. The slow charging gun can also be unlocked manually. Generally, there is an unlocking rope near the slow charging interface in the car, which can be unlocked by pulling it.

1. The slow charging port is at the front of the car, please open the hood, the slow charging port is at the rear of the car, please open the tailgate
2. Look inside the car corresponding to the slow charging port, some models may be covered by a cover
3. Pull the rope to unlock, you can draw the gun

4. If the above methods do not work, you can contact the customer service of the charging pile to try to unlock it remotely, or the maintenance personnel can go to the scene to solve the problem. Please
Do not pull violently to avoid equipment or vehicle damage.

9. Will there be radiation from electric vehicles or charging stations?

Answer: There is electromagnetic radiation, but it has no effect on the human body.

1. Electromagnetic radiation is everywhere. The earth is a huge electromagnetic field. Sunlight and all household appliances have electromagnetic radiation. As long as the intensity is lower than a certain intensity, it is harmless to the human body.

Low-intensity electromagnetic radiation is harmless to the human body

Low-intensity electromagnetic radiation is harmless to the human body

2. The country has strict standards for electromagnetic radiation of various equipment. The measured data shows that the electromagnetic radiation intensity of electric vehicles is lower than that of commonly used smartphones.

Electric vehicles emit less electromagnetic radiation than smartphones

3. Only high-intensity electromagnetic radiation and ultra-high-frequency ionizing radiation are harmful to the human body, and it is necessary to keep a distance to avoid excessive exposure.
Such as TV transmission towers, large substations, X-ray perspective equipment in hospitals, etc.
