When we see “tested under laboratory conditions”, we often assume real-world conditions will lead to faster degradation of a product. But experts from Stanford University have found the opposite is true for electric vehicle (EV) batteries. Their new research shows traditional laboratory testing leads to faster degradation, while real-world use gives substantially more battery life, extending the lifespan of the entire EV. Researchers found the stop-start way we drive and the variable rate the battery discharges power actually prolongs battery life by up to 38% compared to traditional tests. This is good news for EV drivers – and for efforts to electrify transport. This extra battery life would translate to more than 300,000 more kilometres an EV could drive before needing battery replacement, the researchers say.
