Abstract: The lithium-ion batteries used in electric vehicles have a shorter lifespan than other vehicle components, and the degradation mechanism inside these batteries reduces their life even more. Battery degradation is considered a significant issue in battery research and can increase the vehicle’s reliability and economic concerns.
Scientific Reports 14, Article number: 688 (2024) Cite this article The negative impact of used batteries of new energy vehicles on the environment has attracted global attention, and how to effectively deal with used batteries of new energy vehicles has become a hot issue.
Like all batteries, the cells that power an EV will degrade over time. However, our data shows that while battery degradation in EVs is an issue, it’s not as bad as you might think. In our survey, we asked over 3,000* owners of EVs to tell us by how much the range of their car had decreased since they bought it. *Source: Latest Which?
A probabilistic life cycle assessment was conducted using Monte Carlo simulation. Reuse of expired electric vehicle batteries can improve environmental sustainability. Battery usage purpose with efficiency should be considered during entire lifecycle. This study can contribute to crafting rational environmental impact policies.
EVs battery that does not meet the recombination requirements are reused. Secondly, EVs battery whose capacity is reduced to less than 80 % and cannot be applied to new energy vehicles will be used in cascade utilization.
“When the electric vehicle market started, there was a large concern around the factors that can lead to increased battery degradation,” says Neil Cawse, CEO of Geotab. “For example, discharging completely, charging in cold weather versus warm weather, using high-speed charging versus low-speed charging.
