Abstract
A cell system includes: a stacked-type cell module () having a plurality of lithium ion unit cells () being stacked and having through holes () formed therein; a gas supply part (); a cooling liquid supply part (); a temperature sensor (); and a control part () that controls switching between a normal control mode and a high-temperature control mode based on a signal from the temperature sensor (). In the normal control mode, the control part () controls the gas supply part () to supply a gas to the through holes (), and at the same time, controls the cooling liquid supply part () to stop supply of a cooling liquid, and in the high-temperature control mode, the control part () controls the cooling liquid supply part () to supply the cooling liquid to the through holes () to which the gas is supplied, and at the same time, controls the gas supply part () to stop supply of the gas. According to this cell system, the increase in temperature of the cell is suppressed while having a simple configuration with a reduced formation region of through holes provided in a lithium ion cell.
