It’s interesting about the Chevy Volt.
Uniquely, it carries around its own recharger – so it’s not tied to a corded umbilical like other electric cars. So it isn’t gimped by a much-abbreviated radius of action, like all other electric cars – the best of which can travel maybe 150 or so miles before their batteries conk out and the car must hook up to an electric IV for an extended recharging session.
When the Volt’s battery pack’s charge runs down, fresh current is fed into it as you drive – without having to stop driving.
This is superficially similar to the way a hybrid works but also very different.
