Full charging can reduce battery life
Full charging of electric cars is one of the reasons that affect the battery life. lithium-ion battery, a popular battery used in electric cars, is best when maintaining a charging rate of 20 - 80%. Overcharging can put stress on the battery, especially in harsh environmental conditions such as high temperatures.
Dr Alan Green, a renewable energy expert at the University of Cambridge, shared: "Consistent full charging of electric vehicles will reduce the battery's long-term energy storage capability. To prolong battery life, users should try to keep the charging level below 100%, ideally from 80 - 90%".
Electric vehicle batteries are not like those of mobile devices, they need to be better managed to avoid being " revoked" after a long time of use. Overcharging increases the oxidation process in the cells of the battery, leading to reduced performance and energy storage.
Temperature and full charging affect performance
Another factor that electric vehicle users need to pay attention to is the impact of temperature when fully charged. When the battery is fully charged, it tends to heat up, especially in high- Temperature environments. This high temperature can reduce the performance of the battery and lead to overheating, reducing the battery's ability to maintain travel distance.
When the battery is 100% functional, it not only retains energy but also generates heat, continues Dr Green. Continuously charging at full capacity not only reduces performance but can also cause safety problems related to overheating".
Full charging can also increase maintenance and battery replacement costs, as users will have to replace the battery when the performance of the old battery drops below the acceptable level.
Benefits of charging below 100%
Charging an electric car battery at a level below 100% not only helps prolong battery life but also helps save energy and reduce waste. In addition, charging in the range of 80 - 90% also helps drivers control battery performance better on long trips.
Some electric car manufacturers have provided optimal charging capabilities, allowing users to easily limit the battery charging limit to below 100%. This helps protect the battery and increase vehicle usage time.
