How do hybrid car batteries perform in the cold?

Batteries, in general, suffer some performance issues because of internal resistance in extreme cold, but hybrid cars use thermal management systems to overcome these issues. In cold weather, hybrid cars employ different strategies to quickly get the battery up to a more acceptable operating temperature as soon as the car is turned on.

In my experience, in extreme cold, the slight loss in battery capability while the hybrid battery pack comes up to operating temperature is nearly undetectable in full hybrids such as the Prius and Ford Escape Hybrid. And certainly once the hybrid battery packs are at operating temperature, there are not performance an issues.

But in some mild hybrids, such as the Honda Insight, the performance loss while the battery pack gets up to operating temperature, may be more noticeable.

Granted, it takes a short time to get up to operating temperature, but it is still worth noting. Once again, when the hybrid battery pack reaches operating temperature, there are not performance issues.

Does It Need To Be Plugged In? No, the system constantly monitors the energy state of the battery and uses the gas engine, coupled with the generator to keep the battery charged. The Prius also recaptures the otherwise wasted kinetic energy when braking or decelerating to charge the battery.
