When using electric vehicles, many drivers have the habit of turning on the air conditioner during charging, especially during waiting time at public stations. However, not everyone clearly understands how this affects the battery and charging performance of the vehicle. Although not dangerous, if not used properly, this action can make the charging process less efficient.
Using air conditioners while charging is not harmful, but the effectiveness should be considered
When turned on the air conditioner while charging, the electric vehicle's battery system must simultaneously perform two tasks: charging and supplying power to operating equipment such as air conditioners, screens or other utilities. This causes energy to be consumed right at the charging time, leading to reduced charging speed.
In addition, the use of air conditioners increases the temperature in the battery compartment, forcing the district heating system to work harder to keep the temperature stable. This not only slows down the charging process but also consumes more energy, affecting overall performance.
Many people have the habit of opening the hood when charging an electric vehicle, thinking that it will help the battery system cooler. However, in reality, the battery is often located under the floor and has been integrated with a specialized cooling system. Opening a hood does not help improve heat generation, but sometimes causes trouble, such as the risk of insects or small animals crawling into the engine compartment, especially at night or in places with few people passing by.
How to charge an electric vehicle effectively and protect the battery
To ensure the charging process is quick, safe and helps prolong the life of the battery, users should pay attention to the following points:
Charge in cool times, such as early morning or late afternoon, to limit battery heat.
Avoid charging in hot weather or in conditions with too high environmental temperatures.
If using a fast charger, you should stop at 80% and then switch to slow charging, both protecting the battery and giving the fast charging station to another vehicle.
It is advisable to charge the vehicle at night or early morning, when there are few people using electricity to ensure a stable power source and a charging station operating more efficiently.
Limit the use of devices that consume a lot of energy while charging such as air conditioners, heating chairs, entertainment screens, etc.
Note
Using air conditioners while charging an electric vehicle is technically completely safe, but not the optimal choice if you want to charge quickly and protect long battery life. For best results, choose the right charging time, limit the use of air conditioners during charging and create a cool environment for the battery system to operate more stably and efficiently.
