Are new energy vehicles resistant to high temperatures in summer?
2 Answers
Summer brings high temperatures, but there is no problem for the battery safety of vehicles, so new energy vehicles are relatively resistant to high temperatures. Precautions are as follows: 1. Avoid charging: In the current high-temperature weather, electric vehicles should try not to charge for a long time under direct outdoor sunlight. First, it is better for the maintenance of electric vehicles, and second, it avoids the risk of battery damage or even spontaneous combustion. The battery is sensitive to temperature during use, and the current working temperature range of lithium batteries is -20°C to 60°C. 2. Risk of explosion: When the ambient temperature exceeds 60°, as the battery heats up during operation, lithium batteries have the risk of overheating, burning, and explosion. However, the probability of spontaneous combustion of electric vehicles is extremely small. If accidents occur, they are mainly caused by aging circuits or short circuits caused by water.
I've been driving a new energy vehicle for three years now, and every summer I have to be extra cautious. High temperatures have a significant impact on the battery, especially when the air conditioning is turned on—the range immediately drops by 10% to 20%, making it feel like the battery power is evaporating. I've tried preheating the battery, parking in underground garages or under shade to avoid direct sunlight. Once, I left a thermometer in the car, and after being exposed to the midday sun, the temperature soared to 50 degrees Celsius. The battery was noticeably heating up, but using thermal insulation film improved the situation. A friend mentioned that frequent fast charging can accelerate aging, so I try to opt for slow charging whenever possible. Overall, the car handles heat fairly well as long as you take precautions and avoid leaving it baking in the sun. I recommend that owners pay more attention to battery health in the summer, regularly check the cooling system, and avoid setting the air conditioning too low—around 22 degrees Celsius strikes a good balance between comfort and energy efficiency.
