【Abstract】 A hybrid-drive system consisting of ultracapacitors and a battery pack was established with Matlab/Simulink toolbox.Under the precondition to assure the brake efficiency and stability,the used control strategy was established in order to make full use of the regenerative energy effecency of ultracapacitors and to reduce the discharge current of the battery pack.The parameter matching of the hybrid-drive systerm was completed based on the control strategy.Simulation results show that the design is helpful to prolong the lifetime of the battery pack and increase the running range of vehicle.更多还原
