Interesting. Not surprising but reassuring.


Key Insights

• EV battery lifespan: Most EV batteries last 15-20 years, with an average degradation rate of about 1.8% per year under moderate conditions.
• Impact of charging methods: Frequent use of DC fast charging can accelerate battery degradation, especially in hot climates. Level 2 charging is gentler on the battery.
• Best practices for battery health: To extend EV battery life, keep the state of charge 20%-80%, minimize exposure to extreme temperatures and limit fast charging when possible.

What are common factors that impact battery lifespan?
Modern battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) primarily use lithium-ion batteries, known for their efficiency and durability. However, several factors influence how long these batteries last and why their range may decline over time:

• Age: All batteries degrade over time, reducing capacity.
• Temperature: Extreme heat or cold accelerates wear, emphasizing the importance of thermal management.
• Operating state of charge: Keeping the charge between 20% and 80% minimises strain.
• AC vs. DC charging: Frequent DC fast charging may degrade batteries faster than slower AC charging.
• Usage (energy cycles): Each charge-discharge cycle slightly impacts capacity.
• Battery chemistry: Lithium-ion types, such as NMC or LFP, vary in durability.
• Battery system and thermal management: These features help maintain efficiency and prevent overheating.
