Abstract
A regenerative braking system for an electric vehicle having front and rear wheels, and includes a drive wheel, an actuating device, a regenerative braking control circuit, and a power electronics circuit. The regenerative braking control circuit includes a potentiometer ir transducer, a process sensor, and a microprocessor. The system applies a regenerative braking torque to the drive wheel when the rider commands regenerative braking, and the process sensors signal a drive wheel velocity greater than zero. The present invention also relates to a throttle for actuating regenerative braking and reversing feature.
Claims30
A vehicle, comprising:
- at least two wheels;
- a rechargeable battery;
- and
- a regenerative braking system comprising:
- a brake control configured for movement by a user,
- a regenerative device associated with the batteries and at least one of the wheels for generating an electrical current by decelerating the wheel, and
- a processor connected to the brake control and to the battery such that in response to first movement of the brake control, the processor causes the regenerative device to decelerate the vehicle and charge the battery with said current, wherein the processor is configured for activating another operation of the vehicle in response to a second movement of the brake control second movement.
A electric vehicle, comprising:
- a vehicle frame supporting a plurality of rechargeable batteries;
- at least two wheels supportively connected to the frame;
- an electric motor operatively connected to drive at least one of the wheels;
- a motor controller configured to connect said plurality of batteries to the electric motor;
- and
- a regenerative braking system including:
- a processor having a least one electrical connection to the motor controller, and
- an actuating device mounted on the vehicle and connected to the processor, the actuating device being configured to:
- accelerate the vehicle in response to a first movement of actuating device, and
- apply a regenerative braking force which causes the vehicle to decelerate and the motor controller to recharge at least one of said plurality of batteries, in response to a second movement of the actuating device, while the vehicle is traveling in a forward direction.
A electric vehicle having a regenerative braking system, the vehicle comprising:
- a vehicle frame supporting a plurality of rechargeable batteries;
- at least two wheels supportively connected to the frame;
- a handlebar rotatably connected to the frame and operatively connected for steering at least one of the wheels;
- an electric motor operatively connected to drive at least one of the wheels;
- a motor controller configured to connect said plurality of batteries to the electric motor;
- and
- a regenerative braking system including:
- a processor having at least one electrical connection to the motor controller, and
- a twist-grip throttle mounted on a handlebar of the vehicle and connected to the processor, the twist-grip throttle being configured to:
- accelerate the vehicle in response to a first movement of the twist-grip throttle, and
- apply a regenerative braking force which causes the vehicle to decelerate and the motor controller to recharge at least one of said plurality of batteries, in response to a second movement of the twist-grip throttle while the vehicle is traveling in a forward direction.
