Abstract
A utility vehicle with regenerative braking is disclosed. The utility vehicle includes a system power bus, a battery coupled to the system power bus, at least one electric drive motor configured to generate power through the regenerative braking and supply the power onto the system power bus, and a first controller configured to decrease a maximum travel speed to reduce an amount of the power generated through the regenerative braking when the battery is fully charged and the power is greater than a power consumption limit.
Claims18
A utility vehicle with regenerative braking, comprising:
- a system power bus;
- a battery coupled to the system power bus;
- at least one electric drive motor configured to generate power through the regenerative braking and supply the power onto the system power bus, wherein the at least one electric drive motor is configured to generate the power through the regenerative braking when:
- a torque of the at least one electric drive motor is increasing and a rotational speed of the at least one electric drive motor is decreasing;
- or
- the torque of the at least one electric drive motor is decreasing and the rotational speed of the at least one electric drive motor is increasing;
- and
- a first controller configured to decrease a maximum travel speed to reduce an amount of the power generated through the regenerative braking when the battery is fully charged and the power is greater than a power consumption limit.
