BOOST SYSTEM FOR AN ELECTRIC VEHICLE, ELECTRIC VEHICLE HAVING SAME, AND METHOD FOR BOOSTING A SPEED OF AN ELECTRIC VEHICLE

A boost system for an electric vehicle having an electric motor, a battery pack and a control unit (CU) is provided. The CU controls an operating torque of the electric motor. The boost system has a manual boost controller and a boost mode manager. In response to the manual boost controller being activated, the boost mode manager is configured to determine a remaining boost energy. The remaining boost energy is a difference between a predetermined maximum boost energy and a total boost energy used. The predetermined maximum boost energy corresponds to a percentage of energy of the battery pack. In response to a boost enable condition, the boost mode manager is configured to send a command to the CU to add a boost torque to the operating torque. The boost enable condition includes the remaining boost energy being greater than zero.
