Analysis study on electric vehicle lithium ion polymer batteries COP in various temperature condition in a confined space – review of recent literature

Abstract

The lithium ion polymer batteries are quickly emerging as the preferred electrical energy storage technology and generally used in portable electronics products such as notebook computers, tablets, smart phones and so on. Besides, this technology also attracts worldwide attention in transportation application including the electric vehicles. Electric vehicles (EVs) are becoming more appealing options over combustion engine based vehicles, due to ever rising fuel prices and growing environmental concerns. Demand for electric vehicles (EVs) is increasing, and lithium ion polymer batteries with increased ranges will be critical to increase the marketability and important step in reducing greenhouse gas emissions. However, the current electric vehicles (EVs) are a temporary solution to create more zero emission when run on the road. In additional, the temperatures of lithium ion polymer batteries play an important role in determining the performance of an electric vehicle (EV). It also directly affects the vehicle dynamic performance, reliability, long term durability and safety. From the review, I found that the battery should operate within a temperature range to achieve desired performance and calendar life. All electrochemical batteries are strongly linked to their thermal state. The electrical characteristics are strongly dependent on temperature while the thermal state is a result of both their environmental temperature, but also the electrical usage due to internal heat generation. This is because higher or lower than normal temperature might affect the performance, charging and discharging rate, battery lifespan, battery capacity and maintenance requirements. In general, a battery in a cool location has a longer lifespan than in a warm location. Therefore a solution needs to be solved to maximizing the COP of the battery management. In this paper a brief review of related current literature on electric vehicles (EVs), lithium ion polymer batteries, and ambient temperature conditions are provided. This paper also concludes with direction for future research.
