Oops! Old drivers, today we have to talk about this topic – can you turn on the air conditioner when charging a new energy vehicle? I saw that the debate on the Internet was so lively. Some said it could be turned on, some said it couldn’t be turned on, and some friends even broke the control motherboard because of this! So, who is right?
The truth about turning on the air conditioner while charging is like this
The answer is: it can be turned on, but it is not recommended!
Now explain the reason: turning on the air conditioner while charging will add extra burden to the power battery pack, and the battery has to continue working before it is fully charged. In this way, the battery attenuation rate will soar, and it won’t take long before your battery life will be reduced, and it will even increase the risk of spontaneous combustion. It’s so scary!
I have a car friend who fell here. A certain brand of new energy vehicle, the manual clearly states that it can be charged under any conditions, but he turned on the air conditioner to charge, and the control motherboard went on strike! Later, the after-sales service also confessed that it is more reliable to turn off the engine to charge.
But then again, the specific situation needs to be analyzed specifically:
DC fast charging: high power, it is not a big problem to turn on the air conditioner, but the charging time will be prolongedAC slow charging: power over 7kW, barely can be turned on; less than 7kW, then don’t turn it onMy suggestion is very clear: no matter what the situation, it is best to turn off the air conditioner and turn off the car when charging. Safety first, battery health second, why take this risk?
By the way, there is an exception that must be reminded to everyone-friends with electronic medical devices such as pacemakers, cardiovascular defibrillators, and insulin pumps should never stay in the car when charging! The electromagnetic field generated by the charging of electric vehicles may interfere with the normal operation of these devices, and the consequences are unimaginable.
Battery maintenance taboo 1: Treat the charging gun as a toy
Some car owners are really casual, just put the charging gun on the car and it’s done, and they don’t care whether the charging port is dirty or water ingress. What’s more outrageous is that some people pull out the gun without pressing the unlock button! Interface deformation is a small matter, what if it causes a short circuit and the car spontaneously catches fire?
Here is a tip for the correct method:
Wipe the charging port clean with a glasses cloth before plugging in the gun (usually in the emergency kit in the car) You can let go only when you hear the “click” mechanical lock sound. When you pull out the gun, unlock the car first, press and hold the key unlock button for 3 seconds, and wait until the green light on the gun head goes out before pulling it out. Special reminder to Tesla owners: Never pull out the gun directly during charging, otherwise it will trigger the fuse protection and trouble will come.
Battery maintenance taboo 2: Charging is like punching in for meals
Do you have to charge to 100% every day to feel at ease? Or do you charge it when the power drops to 10%? Both extreme practices are life-threatening!
Depending on the type of battery, the maintenance method is also different:
Lithium iron phosphate battery: fully charge and calibrate the power at least once a week. Ternary lithium battery: You only need to charge to 90% on a daily basis, and there is no need to charge it to the full. The golden charging range is 20%-80%. This range has the fastest charging speed and the least damage to the battery. I suggest that you charge as you use it, and don’t wait until it is almost out of power before charging, which is particularly unfriendly to the battery life.
If the car is to be parked for a long time, it is best to keep the power at 50%. It will not damage the battery by over-discharging, nor will it accelerate aging due to long-term placement of the full charge.
Taboo of battery maintenance three: not paying attention to charging equipment
Some car owners save trouble by using miscellaneous brand charging cables, or even directly using temporary electricity on the construction site, and there are also flying wires for charging, which makes me sweat! These behaviors are all burying time bombs for spontaneous combustion accidents!
Be careful when choosing charging:
Identify the national standard charging pile, which must have CCC certification. The home charging pile must take an independent line and should not be shared with the air conditioner. Before charging in rainy days, check whether the waterproof ring of the gun head is intact. Want to be cheap and safe? Search for “flame retardant socket protection box” on Pinduoduo, and you can get it for twenty yuan, which can save lives at critical moments.
Taboo of battery maintenance four: not paying attention to high temperatures in summer
There is a reason why the spontaneous combustion rate of new energy vehicles is high in summer! High temperature + long distance + fast charging, these three factors combined are simply the three elements of fire!
After being exposed to the sun in summer, the temperature in the car soars, and the temperature of the battery box is frighteningly high. If you charge at this time, the line will age faster. What’s more terrible is that if you have just finished a long-distance drive, the battery itself is in a high temperature state. If you use DC fast charging, the battery temperature will explode directly, and it will not be long before spontaneous combustion occurs.
Summer charging suggestions:
Prefer slow charging. If you must charge quickly, let the car cool down for a while, and then charge the battery after it cools down. 6 Battery maintenance taboo five: Ignore the risk of thunderstorm weather
Charging new energy vehicles in thunderstorm weather is simply playing Russian roulette! Combustion accidents caused by lightning strikes are no joke.
Don’t take it lightly. A friend of mine charged her new car at a charging station some time ago until it smoked, and the repair bill was directly in the five figures! This lesson is too painful.
Ultimate life-saving tips: Don’t sleep, watch TV, or turn on the air conditioner in the car while charging. You must know that the system will automatically cut off the power if it overheats. If there is any accident, the consequences are unimaginable.
Must-see self-check tips
Do you smell burning when charging? Press the emergency stop button immediately! The car computer shows abnormal charging? Contact the 4S store quickly! Remember to check the sealing ring of the charging port every month to see if it is aging. The subsidies for new energy vehicles are not small now, but if they are not properly maintained, the repair costs are also quite scary.
I know that some car companies have launched car repair cashback activities, with a maximum return of 5,000 yuan per time, which can indeed reduce a lot of burden.
Instead of spending money to repair the car, it is better to keep these charging taboos in mind and let your car live a few more years!
