EVs struggle in US heat wave.
Prepare Your Electric Vehicle for the Summer Heat
As the summer months heat up, electric vehicle owners need to take extra precautions to ensure optimal performance. The United States has been experiencing record-breaking heat this year, with millions receiving weather advisories for the ongoing heat wave in the U.S. Southwest. These rising temperatures can have a significant impact on EV drivers, causing their car battery power to drain more quickly.
The Effects of Extreme Heat on EVs
A study conducted by Recurrent Auto has shown that cold weather can reduce the range of electric vehicles by up to 35%. However, warmer temperatures can also have adverse effects on EVs. The battery’s state of health can deteriorate faster, leading to the need for battery replacement sooner than expected.
Lithium-ion batteries, which are commonly used in plug-in hybrids and electric vehicles, are particularly susceptible to the negative effects of heat. According to Greg Less, the technical director of the University of Michigan Battery Lab, temperatures above 104 degrees Fahrenheit can cause a breakdown of the passive emission layer on the battery’s anode. This breakdown leads to the consumption of the liquid electrolyte, ultimately shortening the battery’s lifetime.
While hot temperatures don’t have as drastic of an effect as cold temperatures, AAA reports that when temperatures reach 95 degrees Fahrenheit and the air conditioning is on, the driving range of an EV decreases by an average of 17%.
Proper Care for Longevity
Most EV batteries have a life expectancy of 15 to 20 years. However, proper care is crucial for maximizing the longevity of the vehicle. Recurrent Auto recommends parking your EV in the shade during the warm months and allowing the car to cool down before charging.
Don’t let the summer heat take a toll on your electric vehicle. Take the necessary steps to protect your battery and ensure optimal performance throughout the season.
