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.

As soon as you are ready to move forward the Prius comes
to life, providing the right combination of propulsion.
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
