Thermal battery for heating vehicles
First Claim
1. A system for heating a component in an electric vehicle, the vehicle is primarily powered by a main battery, said system comprising:
- a supplementary battery being metal-air battery comprising an electrolyte;
a reservoir tank for holding electrolyte volume for the metal-air battery, the electrolyte volume usable as a thermal battery for preserving heat;
a heating element powered by an external electric source, for heating the electrolyte in said reservoir tank before the electric vehicle is started; and
a heat exchanger for conveying heat from the electrolyte, said heat being conveyable to said component.

Abstract
A system and a method for heating a component of an electric vehicle may be particularly beneficial in cold weather places and/or during winter time. The vehicle may be primarily powered by a main battery. The system may include a supplementary battery being metal-air battery including an electrolyte, for extending the driving range of the electric vehicle and a reservoir tank for holding an electrolyte volume for the metal-air battery, the electrolyte may be heated to a desired temperature. The system may further include a heat exchanger for conveying heat from the electrolyte volume, said heat is conveyable to said passenger'"'"'s cabin.
