Why do electric vehicles (EVs) batteries drain faster during winter

The complex relationship between temperature and batteries make EVs batteries to drain much faster during winter than other climatic seasons. Most EVs batteries are built with Lithium-ion, which uses chemical reactions to store, retain and release electrical energy. The Lithium-ion batteries chemical reactions are very sensitive to temperature and this is why any Lithium-ion battery drain easily during winter. Cold weather increases a battery’s internal resistance, slowing lithium-ion movement and reducing its energy capacity and efficiency. So, it’s completely normal for batteries (especially ones built with Lithium-ion) to drain easily and drastically during the winter periods. More theories and practicals backed this up; colder temperatures increase the viscosity of electrolytes—the liquid that enhances the movement of ion in batteries. In practical terms, an EV’s range can drop by 20-30 percent in freezing conditions, making EV winter performance less than optimal. Speaking less of h…
