This research focused on the performance analysis of an electric car when using different battery types. The electric car was built specified for the experiment. It was equipped with a 5 kW BLDC motor. The lithium-iron phosphate battery and deep cycle lead-acid battery with equal capacity of 48V 120 Ah were selected. The electric car was tested on a chassis dynamometer with two modes of testing, there were twice run of five urban cycles, and continuous drive on urban driving cycle until the electric car unable to reach 50 km/h. While testing, the electric power analyzer was conducted for recording various electric data. The results showed that the electric car when using lithium-iron phosphate battery could respond to reach the target velocity curve profile better than when using deep cycle lead-acid battery. In addition, the driving range per charge of the electric car using lithium-iron phosphate battery was longer as well.
