vehicle with a super capacitor for braking energy recovery

摘要

Has energy storage system for at least 70 kJoules to 150 kJoules.. The vehicles electric traction system includes: (a) acceleration and deceleration controller (CA) available to the driver; a processing unit (211,212) for the controller (CA) which checks and evaluates the required engine torque and braking torque; an electrical energy source for traction; an electrical machine (112,231) connected to a drive wheel and coupled to an electrical conductor of the electrical energy source. The electrical machine is capable of operating the engine by absorbing the electrical energy from the electrical conductor and transmitting to the drive wheel a torque. The electrical machine is also capable of operating as a generator by transmitting to the drive wheel a braking torque and returning the electrical energy to the conductor; a storage system (41) for electrical energy from the conductor, the electrical energy storage system consists of one or more super condensers; an operation mode management unit for selecting energy recuperation or restitution; a drive unit (21) for applying torque to the vehicles wheel, which permits (a) at torque demand, the electrical machine to operate as a motor by consuming the stored energy as long as the charge of the storage system is not at a minimum, having priority for use of the energy source for vehicle traction and (b) at a request for braking torque, operate the machine as a generator by using the energy produced to recharge the energy storage system as long as the system charge is not at a maximum, with priority over use of all other braking devices.
