초록
An electric vehicle operates at high currents and requires real-time monitoring of the entire system forensuring efficiency and safety of the vehicle. Current sensors are applied to drive the motors, inverters, andbattery control systems, and are the key components to ensure constant monitoring of the magnitude andwaveforms of the operating current. In this study, a heat treatment process condition to influence theperformance of Permalloy current sensors was developed; the correlation between the output capacity,low-temperature characteristics, and high-temperature characteristics of the current sensor was studied; and theprocess was optimized to meet the required output accuracy and temperature characteristics.
