Abstract
A present invention is a power supply device, comprising a battery unit, a heater configured to generate heat on the basis of power of the battery unit, and a driving unit configured to drive the heater with a driving force according to a temperature of the battery unit.
Claims13
A power supply device, comprising:
- a battery unit;
- a heater configured to generate heat on the basis of power of the battery unit;
- a heater driver configured to drive the heater with a heating level according to a temperature of the battery unit;
- a temperature sensor configured to detect the temperature of the battery unit and is provided on the battery unit at a position different from a position of the heater;
- an acquisition unit configured to acquire a load state of the battery unit;
- and
- a protection unit configured to protect the heater by preventing application of an overcurrent to the heater, wherein
- the heater driver sets the heating level on the basis of the temperature and the load state,
- the battery unit includes a plurality of battery cells electrically connected in series,
- the heater covers the plurality of battery cells across the plurality of battery cells, and
- wherein a portion of the heater that contacts the individual battery cells is defined as a first portion, and a portion positioning between adjacent two of the plurality of battery cells and being separated from the individual battery cells is defined as a second portion, the protection unit is disposed in the second portion.

A power supply device, comprising:
- a battery unit;
- a heater configured to generate heat on the basis of power of the battery unit;
- a heater driver configured to drive the heater with a heating level according to a temperature of the battery unit;
- a temperature sensor configured to detect the temperature and is provided on the battery unit at a position different from a position of the heater;
- an output unit configured to output power to a starting device for starting an internal combustion engine;
- a switch unit configured to set whether or not it is possible to output the power from the output unit;
- and
- a switch control unit configured to:
- determine whether the battery unit is ready to output power required for the starting device to start the internal combustion engine, and
- control the switch unit so that the output of the power from the output unit is realized when it is determined that the battery unit is ready to output power required for the starting device to start the internal combustion engine, wherein
- the switch control unit determines whether the battery unit is ready to output power required for the starting device to start the internal combustion engine on the basis of a temperature of the internal combustion engine.
