This paper discusses the application of OTP(Over-temperature Protection) circuit and EW(Electric Wheelchair) in BLDC motor-battery system using MIT(Metal-Insulator-Transition) device. Recently, a battery system has a problem in that a fire occurs due to inadequate battery design, over charge, over voltage, cell balancing failure, and inadequate BMS(Battery Management System) circuit. Therefore, in this study, the protection circuit that protects the entire system before the battery fire and explosion temperature is studied for proper protection of the battery system. In particular, the metal-insulator instantaneous transition device proposes an over temperature protection circuit that stops the BLDC motor and battery charging when an over temperature occurs to the battery based on a new material called VO₂. The validity of the proposed over temperature protection circuit is applied to 500[W] class BLDC motor and 1500[Wh] classbattery system, and its applicability is discussed.
