Abstract
A method and apparatus for improving the run duration of an electric motor powered by a battery pack is provided. The apparatus includes an electric motor having a rated motor voltage, a battery pack having an output voltage exceeding the rated motor voltage, and a motor controller which converts the output voltage to supply electrical power to the electric motor at a second voltage lower than the output voltage.
Claims8
An electrical control system for an electric cart, comprising:
- a battery pack power supply which supplies electrical energy;
- a motor controller which decreases a first voltage of the electrical energy supplied by the battery pack to supply motor power at a second voltage;
- an electrical motor which converts the supplied motor power to torque,
- wherein an output voltage of the battery pack is at least 25% greater than a rated motor voltage.
