Rechargeable battery system for small scale electric vehicle.

Abstract

Popularity of electric vehicle (EV) is growing very rapidly in recent times due to favourable emission regulations and its improved practicality in terms of the battery technology. Because of that, studying the rechargeable battery technologies becomes increasingly crucial. Therefore, this paper describes the work carried out to design a rechargeable battery system that integrate parameters monitoring system. The battery system was designed to be implemented in a small-scale EV that uses 10 kW electric motor. Lithium-ion battery was used in the system due to its relatively high energy capacity and charging cycles. For the monitoring system, three sensors where used; voltage sensor, current sensor and thermocouple, to measure the voltage, current and temperature, respectively. As a result, the battery’s performance and conditions can be monitored during operation.
