BUILDING A MODEL AND SURVEYING THE OPERATION OF BATTERIES IN HYBRID CARS

Abstract

Today, the environment is a particular issue that is always a concern within a
country and spreading worldwide. Pollution caused by motor vehicles is a
problem in all countries. One of the solutions to reduce pollution is to use electric
cars. But electric vehicles also have disadvantages: the production cost of lithium-
ion batteries is high, about 25 - 50% of the total price of an electric vehicle, and
the charging time is longer than refueling. Lithium-ion batteries are emerging as
the most prominent energy storage devices due to their high energy density, good
life cycle efficiency, and low self-discharge rate, attracting much research
attention. Used for pure electric cars and hybrid cars to reduce production costs.
With such an essential role of Lithium-ion batteries in electric vehicles, in this
study, the author goes into building a lithium-ion battery pack and then conducts
simulations on a hybrid car model with a hybrid drivetrain. Suitable to evaluate
the performance of the battery pack. The model runs were performed when the
car operated according to European driving cycles, so the results were reliable.
