In this paper, dual extended Kalman filter is implemented to estimate SoC, internal resistance and capacitance of the super-capacitors applied in hybrid electric vehicles(HEVs) simultaneously based on its first-order equivalent circuit. Both simulation and experiment are carried out to verify the performance of the algorithm. Simulation results demonstrate that the algorithm reduces the estimate errors...
In this paper, a coordinated braking control scheme is presented for hybrid duty trucks. A key problem to improve the efficiency of regenerative braking without loss of comfortability is the coordinated operation between the regenerative braking and the mechanical braking torque generated by the electrical motor and the air-over-hydraulic brake, respectively. Furthermore the gear shifting operation...
