5. An electric battery is a device consisting of two or more electrochemical cells that
convert stored chemical energy into electrical energy. Each cell has a positive terminal,
or cathode, and a negative terminal, or anode. The terminal marked positive is at a
higher electrical potential energy than is the terminal marked negative. The terminal
marked positive is the source of electrons that when connected to an external circuit
will flow and deliver energy to an external device.
The usage of "battery" to describe a group of electrical devices dates to Benjamin
Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of
cannon.(Benjamin Franklin borrowed the term "battery" from the military, which refers
to weapons functioning together). Alessandro Volta built and described the first
electrochemical battery, the voltaic pile, in 1800. This was a stack of copper and zinc
plates, separated by brine-soaked paper disks.

6. Batteries convert chemical energy directly to electrical energy. A battery consists of
some number of voltaic cells. Each cell consists of two half-cells connected in series
by a conductive electrolyte containing anions and cations. One half-cell includes
electrolyte and the negative electrode, the electrode to which anions (negatively
charged ions) migrate; the other half-cell includes electrolyte and the positive
electrode to which cations (positively charged ions) migrate. Redox reactions power
the battery. Cations are reduced (electrons are added) at the cathode during charging,
while anions are oxidized (electrons are removed) at the anode during
charging. During discharge, the process is reversed.

8. There are some types of batteries for EV such as Lead-Acid, Lithium-
Ion, Nickel-Cadmium and Nickel-Metal-Hydride. To model battery,
selection of battery is one of the most crucial factors that have to be
considered.
However the first priority considering EV is how long EV can drive
with the battery. Therefore, weight and energy density of the battery
should be considered first.
Hence, the battery which has high energy density and low weight
should be contemplated to use for EV. In this respect, Li-Ion batteries
are getting the limelight because of its high energy density and
relatively low weight.Therefore, Li-Ion battery is used for EV.

16. Final Simulation result

17. This research demonstrates that the matlab simulation battery
model allows for an adequate representation of a battery’s real
behavior. In battery simulation model it has been found that
less internal resistance gives more efficient output. Energy
density and weight of the battery is the main factor to choose a
battery. In this respect, Li-ion batteries are getting the limelight
because of its high energy density and relatively low weight.
Therefore, we used Li-ion battery.
