Why Does the Range of Pure Electric Vehicles Decrease in Winter?
1 Answers
Reasons for the reduced range of pure electric vehicles in winter: The lower the temperature, the lower the activity of the electrode materials, the fewer lithium ions move in the electrolyte, and the higher the energy required to drive their movement. Under these conditions, the observed phenomena are reduced battery capacity and shorter vehicle range. However, this capacity reduction is temporary and can return to normal when the ambient temperature rises and discharge conditions improve. Lithium batteries refer to batteries containing lithium in their electrochemical systems, including lithium metal, lithium alloys, lithium ions, and lithium polymers. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium, while lithium-ion batteries do not contain metallic lithium and are rechargeable.
