Hybrid Combination Of Battery & Supercapacitor As Energy Storage For EV”
Abstract
On increasing demand of electric vehicle,
efficiency and performance plays a very vital role
and it depends upon the energy storage system of EV.
In this thesis , a new battery super capacitor hybrid
energy storage system is proposed to meet the
requirement . For automotive applications, the
batteries are sized to ensure many constraints like
start up, acceleration, braking and energy recovery.
All these constraints give us a very heavy battery
with very high energy compared to that required for
these applications. To reduce the weight of the
storage system, the battery can be associated with
high power component like supercapacitor.
It is one of the crucial task to improve both efficiency
and performance of the electric vehicle regarding
electric power density and energy capacity.
Supercapacitor integrates system by means of static
power converter. These systems can be completely
electric or by using Fuel cell.The MATLAB
simulation is performed to evaluate its performance
and investigate the mitigation of battery stresses.
Simulation model of hybrid energy source is
presented and used to investigate the design
optimization of electric vehicle on board of energy
source in terms of energy efficiency and storage
mass. Introduction of super capacitor reduces
electric stresses, increases efficiency and enhances
the overall performance.
