ABSTRACT:
In these modern days, electric vehicles are well known for its efficiency, it would be a cost saving choice
compared to the ICE car, due to its advantages such as silent engine, zero emission which are totally
green to the environment. However the selection of a suitable battery type such as lead acid, NiMH,
Lithium ion in the long run plays a very important role in the construction or design of the electric vehicle
due to its function and also the physical aspects. In terms of the functionality, the vehicle must be able to
provide sufficient energy to allow the car to move or accelerate
and at the same time, having a long
lifespan or constant power supplied to the vehicle. Taking this into consideration, lithium ion battery have
been selected as the main power source when designing an electric car, this can be viewed from the
characteristics of a lithium ion battery such as fast charging rate, light weight, high capacity and long
charge-discharge cycle, etc. Hence the design of battery pack using lithium ion battery inclusive of its
compartment design, ventilation and the monitoring system will be discussed in this paper.
