Much like internal combustion engines, battery-electric motors have to battle heat to maximize performance.
“Heat is always the enemy,” said Greg Less, technical director for the University of Michigan’s battery lab.
Like conventional engines, electric vehicles (EVs) have to dispel heat that’s generated in the battery during charging and discharging. Faster current demands, particularly those experienced during DC fast charging, crank up the heat, which can lead to faster battery degradation and, in some cases, potentially dangerous battery damage if proper safeguards are not in place.
