Abstract: Regenerative braking prov

Abstract: Regenerative braking provides an effective way of extending the driving range
of battery powered electric vehicles (EVs). This paper analyzes the equivalent power
circuit and operation principles of an EV using regenerative braking control technology.
During the braking period, the switching sequence of the power converter is controlled to
inverse the output torque of the three-phase brushless direct-current (DC) motor, so that the
braking energy can be returned to the battery. Compared with the presented methods,
this technology can achieve several goals: energy recovery, electric braking, ultra-quiet
braking and extending the driving range. Merits and drawbacks of different braking control
strategy are further elaborated. State-space model of the EVs under energy-regenerative
braking operation is established, considering that parameter variations are unavoidable due
to temperature change, measured error, un-modeled dynamics, external disturbance and
time-varying system parameters, a sliding mode robust controller (SMRC) is designedand implemented. Phase current and DC-link voltage are selected as the state variables,
respectively. The corresponding control law is also provided. The proposed control scheme
is compared with a conventional proportional-integral (PI) controller. A laboratory EV for
experiment is setup to verify the proposed scheme. Experimental results show that the
drive range of EVs can be improved about 17% using the proposed controller with
energy-regeneration control.
