Electric motor control and Battery Management System of Cikal Cakrawala ITB electric vehicle

This paper focused on a research in typical BLDC controller which is used to drive BLDC motor usually used in electric car and characteristic of Battery Management System planted in Battery. Control of induction motor and PMBLDC (Permanent Magnet Brush less Direct Current) known as BLDC (Brush less Dirrect Current), were discussed. Not only that, Battery Management System for Lithium-Ion Battery was identified. Testing was done on BLDC motor 800 W and LiFePo₄ Battery 48 V nominal. This research was done by connected the controller to battery (LiFePo₄) and BLDC motor with variable load. From this, controller characteristic such as forward drive, reverse, braking, and cruise speed can be shown. Using power meter and oscilloscope, we can analyze how the controller driving the BLDC motor at forward drive, reverse, braking, and cruise speed. Besides that, we get the maximum and minimum voltage, maximum current on BMS that allowed to feed the battery.
