Abstract
A power supply unit comprises a solid electrolyte battery constituted by using a solid electrolyte alone and a liquid electrolyte battery constituted by using an electrolytic solution connected in parallel to each other. Since the solid electrolyte battery is primarily utilized at high temperature and the liquid electrolyte battery is primarily utilized at low temperature, a power supply unit can achieve durability characteristics at high temperature equivalent to those of a power supply unit constituted of solid batteries alone and output characteristics at low temperatures equivalent to those of liquid electrolyte batteries alone, is provided.
Claims22
A power supply unit comprising:
- a solid electrolyte battery constituted by using a solid electrolyte instead of an electrolyte solution,
- a liquid electrolyte battery constituted by using an electrolytic solution connected in parallel to the solid electrolyte battery, and
- a power control device that is connected in series to the liquid electrolyte battery to control a power of the liquid electrolyte battery in conformance to a temperature of at least one of the liquid electrolyte battery and the solid electrolyte battery.
A power supply unit comprising:
- a solid electrolyte battery constituted by using a solid electrolyte instead of an electrolyte solution,
- a liquid electrolyte battery constituted by using an electrolytic solution connected in parallel to the solid electrolyte battery,
- a temperature detector that detects an average temperature of the solid electrolyte battery and the liquid electrolyte battery, and
- a power control device that controls the power of the liquid electrolyte battery in conformance to a temperature detected by the temperature detector.
