Abstract
Disclosed herein are battery systems for electric vehicles. An electric vehicle may include a first battery. The first battery may be configured to power various low voltage systems. For example, the first battery may provide the power to start the vehicle. The vehicle may include a second battery. The second battery may be configured to power one or more electric motors for propelling the vehicle. The first battery may supply power necessary to engage and/or access the power stored in the second battery. The first battery may include a heater to ensure that the first battery can supply ample power to initiate a start sequence in low temperatures.
