Poor cruise performance of Electric Vehicles (EVs) continues to be the primary reason that impends their market penetration.\nAdding more battery to extend the cruise range is not a viable solution as it increases the structural weight and capital cost of the\nEV. Simulations identified that a vehicle spends on average 15% of its total time in braking, signifying an immense potential of the\nutilization of regenerative braking mechanism. Based on the analysis, a 3kWauxiliary electrical unit coupled with the traction drive\nduring braking events increases the recoverable energy by 8.4%. In addition, the simulation revealed that, on average, the energy\ndrawn from the battery is reduced by 3.2% when traction drive is integrated with the air-conditioning compressor (an auxiliary\nelectrical load). A practical design solution of the integrated unit is also included in the paper. Based on the findings, it is evident\nthat the integration of an auxiliary unit with the traction drive results in enhancing the energy capturing capacity of the regenerative\nbraking mechanism and decreases the power consumed from the battery. Further, the integrated unit boosts other advantages such\nas reduced material cost, improved reliability, and a compact and lightweight design.
