  This paper represents a novel regenerative braking approach for the Electric
Vehicles. The proposed method solves the short-range problem which is
corresponding to the charge of the battery pack. The DTC switching algorithm
has been modified to recover the electrical energy from Electrical Vehicle
(EV), driven by Brushless DC motor, without using the additional power
converter or the other electrical energy storage devices. During regenerative
braking process, different switching pattern is applied to the inverter to
convert the mechanical energy to the electrical energy through the reverse
diodes. This switching pattern is different from the normal operation due to
the special arrangement of voltage vectors which is considered to convert the
mechanical energy to electrical energy. The state of charge of the battery is
used as a performance indicator of the method. Simultaneously, a model
reference adaptive system has been designed to tune the system parameters.
Several simulations are carried out to validate the performance and
effectiveness of the proposed methods. The results show the high capability and
performance of the designed method.
