Does fast charging affect the lifespan of electric vehicle batteries?
1 Answers
Impact of fast charging on electric vehicle batteries: 1. Fast charging reduces charging time by increasing charging voltage and current, with typical fast charging stations delivering 60-90kW of power. 2. Excessive charging voltage can impair the battery's reduction capability, significantly affecting its lifespan. Additionally, it may cause rapid temperature rise, potentially leading to thermal runaway and explosion, posing serious safety risks. 3. Both fast and slow charging cause battery degradation since battery lifespan is closely tied to charge cycles. With power battery warranties covering 8 years or 120,000 km, normal usage within warranty periods typically won't result in premature lifespan termination or combustion incidents due to charging.
