Extreme heat does not trap people in electric vehicles

As summer heat waves hit, concerns about the impact on electric vehicles (EVs) have surfaced. Stories of EVs being “bricked” or losing range due to extreme heat have left some owners worried. However, the reality is a bit less dramatic. While heat can accelerate the degradation of EV batteries, it is unlikely to cause sudden failures that leave drivers stranded. In this article, we will explore the effects of heat on EV batteries, debunk myths surrounding extreme heat, and provide tips on how to care for your EV during hot weather.

Discussion: Data from Recurrent’s analysis of 20,000 EVs shows that extreme heat does not brick EV batteries but can cause accelerated degradation. Heat exposure is like drops in the bucket that contribute to the aging process of batteries, affecting their capacity over time. However, modern EVs, such as Teslas, are equipped with smart liquid-cooling systems that help mitigate the effects of heat on battery degradation. Early EV models, like the Nissan Leaf, experienced accelerated degradation due to heat but improvements in battery chemistry have addressed these issues.

– Charging Recommendations
– Parking Considerations
– Thermal Management Strategies

Recommendations for keeping your EV battery safe in hot weather include avoiding full charges, parking in shaded areas, and leaving the battery partially charged when exposed to heat. Setting a charge limit and utilizing active thermal management can help protect the battery from excessive heat. Taking these precautions can help prolong the lifespan and performance of your EV battery.

Don’t be surprised if range takes a heat-wave hit—temporarily

– Impact of Temperature on Range
– Heating vs. Cooling Efficiency
– Managing Range Expectations

In extreme heat conditions, EVs may experience temporary range loss due to the effects of high temperatures on battery performance. The loss of range in hot weather is typically less severe compared to cold weather conditions. Understanding the impact of temperature on range and adjusting expectations can help EV owners prepare for and manage the effects of heat waves on their vehicles.

Overall, while heat waves can affect the performance of EV batteries, the idea of an EV being “bricked” due to extreme heat is largely a myth. By following practical tips and understanding the effects of temperature on battery degradation, EV owners can ensure the longevity and reliability of their vehicles during hot weather conditions. Being proactive in caring for your EV in the heat can help mitigate potential issues and ensure optimal performance throughout the summer months.
