Electric Car is a car that runs using an electric motor that is powered by electricity from batteries or accumulators. Electric cars have several advantages compared to conventional cars, one of which does not require fossil fuels and does not produce emissions of gas. Along with the increasingly popular use of electric cars at this time resulting in many inventions do the research to improve performance, efficiency, and optimization of the electric car. One of the main components of the Electric Car is the Motor and its Controller. Currently, the Motor and Controller are made by foreign nations, so that Research and Development (R&D) of these major components is needed. This Final Project focuses on the design and manufacture of 48DC BLDC motor controller driver systems in which there is a telemetry-based power monitoring system function to facilitate the monitoring process of a BLDC motor. The results of this study produce 48V BLDC Motor Driver Controller with 1KW power capacity. Motor speed regulation can be done by changing the value of Pulse Width Modulation (PWM) through the throttle. From the results of the testing of the Driver Motor Controller, the maximum current consumed by the BLDC motorbike in the burdened condition is 20.3A and the Power is 1000.7 with a speed of 310 RPM. Besides that, the system is also equipped with a power monitoring system that is capable of measuring voltage, speed, current, and power with an average error value <3%, and sending measurement data in the range of 0-100 with an average success of 70%.
