Since it takes a long time to charge the battery to the cut-off voltage in the first stage, several studies replace it with specifically optimized terminal voltages as the transition condition to reduce the total charging time , . Customized number of stages are provided in studies , , .
Batteries contain fluids called electrolytes, and cold temperatures cause fluids to flow more slowly. So, the electrolytes in batteries slow and thicken in the cold, causing the lithium ions inside to move slower. This slowdown can prevent the lithium ions from properly inserting into the electrodes.
Low temperature degrades battery charging due to the following two reasons. First, the deposition of lithium metal on the graphite electrode will occur when the battery is charged at low temperatures, causing loss of cyclable lithium and potential safety hazards .
However, the cold affects chargers in multiple ways too. Matt Teske, Founder and CEO of Chargeway, explains: “Cold weather can affect EV charging hardware, such as the liquid-cooled cables that regulate the temperature of fast chargers. These may also require time to warm up in cold weather, impacting the wait time for a charging session.”
