Abstract
An electric-carrier power-supply device for use in an electric carrier is provided. The electric-carrier power-supply device includes a piezoresistive sensor, a battery interface, and a power-management unit (PMU). The battery interface is connected to an on-board battery and receives power from the on-board battery. The PMU controls power to a motor of the electric carrier. A piezoresistive strain gage is disposed between a contact area between the battery interface and the on-board battery, and is used to detect a pressure value of the contact area. The piezoresistive sensor receives the pressure value detected by the piezoresistive strain gage, and converts the pressure value into a resistance value. The piezoresistive sensor determines whether the resistance value is within a safe resistance value range to generate a resistance-value-determination signal. The PMU determines whether to provide power to the motor is according to the resistance-value-determination signal.
