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.
