A new AI-based charging method can adapt fast charging to a lithium-ion battery, extending its battery life without increasing charging times.
A key barrier to electric vehicle (EV) adoption is access to fast charging to enable commuting and driving over longer distances. However, fast charging can be stressful for batteries, limiting their lifespan.
Researchers at Chalmers University of Technology in Sweden have developed an AI-based charging strategy for EVs that adapts the current during each fast charge to the battery’s chemistry and ‘state of health’. As a result, battery life is extended by around 23% compared to standard methods, while charging time remains largely unaffected.
“We show that it is possible to charge more or less as fast as today, but with significantly less long-term degradation of the battery,” said Meng Yuan, assistant professor at Victoria University of Wellington, New Zealand, and a former researcher at Chalmers.
