This study looks at how temperature affects the performance of lithium-ion batteries in electric vehicles (EVs). Temperature has a big impact on how well these batteries work. When batteries get hot, their resistance goes down, causing heat. Both internal and external temperatures can affect battery performance. EVs can lose driving range in cold weather, which is a downside compared to regular cars. The researchers studied how different temperatures affect these batteries using specific driving tests. They found that temperature is super important for how well EVs can run and how far they can go on a single charge. Getting the temperature just right is crucial for EVs to work their best.
