Abstract
A method and a device for battery detection are provided. In the method, multiple characteristic values measured from a battery during operation of the battery are captured via a data capturing device to form a characteristic curve. Curve fitting is performed on the characteristic curve to obtain a curve error. According to the magnitude of the curve error, it is determined whether the battery is normal. When the determination result is abnormal, a step-curvature radius analysis is performed on the characteristic curve to determine whether the battery is normal.
