Abstract
A system for dynamic battery loading for electric vehicles includes an electric motor to displace a vehicle. A first battery stores a first electric power charge and a second battery stores a second electric power charge. A controller dynamically loads or couples the first battery or the second battery to deliver the first electric power charge or the second electric power charge, respectively, to the electric motor based at least in part on the power signal, a location of the first battery, or a location of the second battery within the vehicle.
