    Abstract: Embodiments of the present disclosure provide a method for temperature detection. The method comprises obtaining a sensed temperature from a sensor, the sensor being in a mounted mode where the sensor is thermally radiated by a variable heat source and a fixed heat source; determining a temperature change rate of the sensor and at least one affecting factor that affects temperature sensing of the sensor; and determining a temperature of the variable heat source based on the sensed temperature, the temperature change rate, and the affecting factor. According to the method of the present disclosure, the temperature of the variable heat source such as an ambient temperature can be obtained or determined without a dedicated sensor and cables. With this method, the ambient temperature can be determined by a sensor for sensing a temperature of a heating element such as a battery, a control unit or the like. In this way, extra spaces and product designs for mounting a dedicated sensor for the ambient temperature are no longer needed, which reduces costs of the product. Furthermore, user experience can be improved without increasing costs.
