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.
