Abstract:
A measurement method, a measurement apparatus, and a computer program product for measuring a thermoelectric module are provided. A temperature is provided to the thermoelectric module. A current is applied to the thermoelectric module to turn both sides of the thermoelectric module into a hot side and a cold side. The temperature of the hot side is higher than that of the cold side. A terminal voltage of the thermoelectric module, a hot side temperature of the hot side, and a cold side temperature of the cold side are measured at different time points. A thermoelectric relationship between the terminal voltages and differences between the hot side temperatures and the corresponding cold side temperatures is obtained according to the terminal voltages, the hot side temperatures, and the cold side temperatures. At least one first parameter of the thermoelectric module is estimated according to the thermoelectric relationship.
