Heating system and battery system
First Claim
1. A heating system comprising:
- an alkaline secondary battery including a power generating element configured to be charged or discharged and a battery case that accommodates the power generating element in a hermetically sealed state; and
a controller configured to control charging and discharging of the alkaline secondary battery and, when an internal pressure of the alkaline secondary battery is higher than or equal to a first threshold, execute a heating process for heating the alkaline secondary battery by decreasing the internal pressure through discharging of the alkaline secondary battery, the heating process raising a temperature of the alkaline secondary battery, whereinwhen the heating process is executed and the internal pressure is lower than or equal to a second threshold lower than the first threshold, the controller is configured to raise the internal pressure by charging the alkaline secondary battery.

Abstract
A heating system includes: an alkaline secondary battery and a controller. The alkaline secondary battery includes: a power generating element configured to be charged or discharged; and a battery case that accommodates the power generating element in a hermetically sealed state. The controller is configured to control charging and discharging of the alkaline secondary battery, and, when an internal pressure of the alkaline secondary battery is higher than or equal to a first threshold, execute a heating process for heating the alkaline secondary battery by decreasing the internal pressure through discharging of the alkaline secondary battery. The heating process is a process of raising a temperature of the alkaline secondary battery.

12. A battery system comprising:
-
an alkaline secondary battery; a temperature sensor configured to detect a temperature of the alkaline secondary battery; and a controller configured to execute a first process at least once when the temperature detected by the temperature sensor is lower than or equal to a predetermined temperature, the first process being a process of decreasing an internal pressure of the alkaline secondary battery, wherein the controller is configured to alternately execute the first process and a second process multiple times when the temperature detected by the temperature sensor is lower than or equal to a predetermined temperature, the second process being a process of raising the internal pressure of the alkaline secondary battery. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
