Analysis of motor power characterization and power efficiency on operation of electric car prototype

The existence of electric vehicles is believed to be a solution to solve issues in the transportation sector nowadays. The development of electric vehicles that are rapidly growth is the motive of the author to conduct research in analyzing the use of power consumption in electric car prototype. Research is carried out by focusing on data processing from two fundamental components in electric vehicles, which are the battery and electric motor. The motor used in this car is 2 kW brushless DC (BLDC) motor type and Lead acid battery. A controller will be used in order to regulate the operation of the electric motor. The research was conducted successfully with two methods: operation of electric car without load and with load on the road. In conditions with no load, the average motor power is obtained at 229.7 watts; in conditions with load on the road, the average motor power is obtained at 639.7 watts. The power efficiency obtained during the test gets a percentage value of up to 84.30%
