Driving cycle based battery rating selection and range analysis in EV applications

Abstract

<p>The energy consumption of electric vehicles (EVs)depends on traffic environment, terrain, resistive forces acting on vehicle, vehicle characteristics and driving habits of driver. The battery pack in EV is the main energy storage element and the energy capacity determines the range of vehicle. This paper discusses the behavior of battery when EV is subjected to different driving environments such as urban and highway. The battery rating is selected based on requirement of driving cycle. The MATLAB/Simulink model of battery energy storage system (BESS) consisting of battery, bidirectional DC/DCconverter and electric propulsion system is built. The simulation is carried out and the performance of BESS is tested for standard driving cycles which emulate actual driving situations. It has been shown that, the amount of the energy recovered by battery during deceleration depends on the amount of regenerative energy available in the driving cycle. If the battery recovers more energy during deceleration, the effective energy consumed by it reduces and the range of the vehicle increases.</p>

Repercussion of effect of different drive cycles on evaluation of electrical consumption for electric four‐wheeler to achieve optimal performance of electric vehicle

“…Saad Alateef et al 13 highlighted importance of accurate EC by using application programming interface. Kezhen Hu et al 14 highlighted driving behavior, individual driving characteristics, traffic conditions, and infrastructure design in the real world is affecting on the electrical efficiency. Experimental test was carried on a Nissan Leaf vehicle under a regular drive cycle with various traffic conditions on the Beijing Road.…”

Mathematical modelling of vehicle drivetrain to predict energy consumption

“…Electric vehicle (EV) energy consumption is affected by the traffic environment, terrain, and resistive forces acting on the vehicle, vehicle attributes, and the driver's driving behaviour. With the above unavoidable circumstances, EVs may face a driving safety issue and deteriorates the EV's energy efficiency [22], [23]. The perceived emergence of electric power train noise and its implications were evaluated to prove the responsibilities of the electrified power train [24].…”
