Title:
THERMOELECTRIC POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/221565
Kind Code:
A1
Abstract:
This thermoelectric power generation device is provided with: a first fluid path (27), in which a first fluid flows; a second fluid path (31), in which a second fluid at a temperature higher than that of the first fluid flows, said second fluid being discharged from an engine (20); a thermoelectric power generator (10), which has a thermoelectric conversion element, and which is provided such that heat of the first fluid can transfer to a first side section (10a), and heat of the second fluid can transfer to a second side section (10b), said thermoelectric power generator generating power by means of a temperature difference between the first side section and the second side section; and a control device (5) capable of acquiring an open voltage and alternating current resistance with respect to the thermoelectric power generator. Just before restarting the engine after an engine stop, the control device determines, corresponding to a detected alternating current resistance, whether a failure of the thermoelectric power generator has occurred or not, in the cases where a detected open voltage is lower than a reference value.
