Electric vehicles more and more into our work and life, some owners of electric vehicles have some doubts about the use of electric vehicles, now the use of electric vehicles in the compilation of some common sense issues for your reference and exchange.
1、Can I turn on the air conditioner when charging? Charging station manufacturers:Yes. Some vehicles need to switch off the system before charging and then start it after charging; new vehicles do not need to switch off the system and can be used all the time.
2、Does turning on the air conditioner while charging affect the battery? It has no effect on the battery, but it affects the charging speed. The air conditioner and the battery are connected in parallel when charging, a small part of the power is used for the air conditioner, and most of the power is used for charging the battery.
Comparing the power distribution data in the above picture, it can be seen that the charging speed of turning on the air conditioner has a small impact during fast charging and a large impact during slow charging.
3、Can I charge in rain or snow or when there is thunder? Electric charging station manufacturers: Yes. There is no water or foreign matter in the interface before inserting the gun, and the interface after inserting the gun is waterproof, so charging in rain or snow is no problem at all. Charging stations, charging piles, wiring, cars, etc. have lightning protection design, charging in thunderstorms is also safe. To be on the safe side, the people concerned should still stay indoors and wait.
4、Can I sleep in the car while charging? It is recommended not to sleep in the car while charging! Limited by the current battery technology, you can move around in the car, but do not sleep in the car. According to national standards, the battery does not catch fire or explode within 5 minutes after thermal runaway occurs so that the car occupants can leave in time.
5, how much power left to charge better? Ev charger ac: It is best to keep the car’s power between 20% and 80%. If the power is lower than 20%, it should be charged. If there is a home charger, you can charge it as you go, and slow charging has no effect on the battery. The car is just a tool, you can drive it when you need it, even if the battery level goes to 0, it will not have any visible effect.
6、How much charge is better? Slow charging has no effect on how much it can be charged, and it is best if it is fully charged. Fast charging is recommended to 80%, some fast charging stations will stop charging automatically at about 95% to avoid overcharging.
Long-term low battery will cause battery life decline, if you don’t drive for a long time (more than 3 months), you can charge it to 80% and park it, and it is recommended to check it once a month, and charge the battery by the way.
7、What are the charging methods for electric vehicles? Nowadays, the charging methods of electric vehicles can be roughly divided into five, which are fast and slow charging, power exchange and wireless charging, and mobile charging.
8、Will frequent fast charging damage the car battery? Frequent fast charging and slow charging compared to the car battery has some damage, will accelerate the car battery core polarisation, resulting in lithium precipitation core. When the lithium precipitation of the core, lithium ions will be reduced, resulting in a decline in the capacity of the car battery, the impact on battery life.
9、What should I pay attention to after fast charging? How to choose between fast charging and slow charging? In addition to lithium iron phosphate batteries, after fast charging, let the car battery rest for a short period of time, lithium metal will turn back to lithium ions, the critical temperature will return to normal values. However, frequent use of fast charging will lead to a reduction in the battery’s restoring ability. In order to make electric cars last longer, car owners may want to choose to use slow charging for daily use, fast charging for emergencies, or slow charging the car battery once a week for battery replenishment.
10、What is wireless charging and mobile charging? Wireless charging, usually without the use of cables and wires, is automatically connected to the power grid for charging and discharging through wireless charging panels embedded in parking spaces and roads; mobile charging is an extension of wireless charging, which makes it unnecessary for car owners to look for charging piles, and enables them to charge their cars while cruising on the road. The mobile charging system will be embedded under a section of the road, with a special section set aside for charging, without the need for additional space.
11. What should I do if I can’t charge a pure electric car? The EV charging process is mainly divided into six steps: physical connection, low-voltage auxiliary power-up, charging handshake, charging parameter configuration, charging, and end shutdown. When charging fails or charging is interrupted during the process, the charging post will display the charging fault reason code. The meaning of these codes can be found online, but the query code is a waste of time, it is recommended to call the charging pile customer service or ask the staff of the charging station to determine whether it is the car or the charging pile caused by the charging failure, or change a charging pile to try.
