Weather of Arabia - At the beginning of July, hot and summer weather prevails in the Arab countries, where high temperatures constitute a constant source of concern for owners of electric cars, as it is noted that the battery discharges more quickly in hot climates compared to normal days, and the reason for this is due to the consumption of part of the energy in cooling. The battery reaches the optimum temperature that allows it to operate at the highest possible efficiency. In this article, we will tell you how your electric car is affected during hot weather

How does hot weather affect an electric car battery?

Answer: Extreme weather, whether extremely cold or hot, can affect an electric vehicle's range. When the temperature drops below 20°F, or rises above 95°F, the battery's range decreases significantly and this decrease in range is temporary, as it returns to its normal level when the temperature moderates.

At high temperatures, chemical reactions inside the battery accelerate, which may lead to the deterioration of its protective structure faster than usual. To deal with these effects, most electric cars are equipped with heating and cooling systems to regulate their temperature, and some companies adjust these systems precisely so that it is not felt. The driver is exposed to the effects of temperature throughout the vehicle, making the instrument panel reading completely unreflective of these effects.

How does heat affect electric cars?

For lithium-ion batteries, excess heat can be harmful as the heat accelerates chemical reactions inside the battery, causing it to degrade faster. This can generate gases that may crack the battery casing, and in extreme cases, the battery may catch fire or explode.

To avoid these risks, electric vehicle batteries use liquid cooling systems to maintain appropriate temperatures. However, it is important to take additional measures to reduce the effect of extreme heat on the battery.

Do you own an electric car? So these tips are for you during the summer

During hot weather, it is recommended to park the car in shaded places, such as under a tree, or in a well-ventilated garage. When charging, it is preferable to give the car a few minutes to cool before connecting it or to use a less powerful charger. In cold weather, it is recommended to preheat the cabin and battery before driving.

Advances in battery technology are promising in reducing the effects of severe weather. We're expected to see solid-state batteries that don't require a liquid component within the next few years, which could reduce range loss due to cold weather conditions.
