Document Type and Number:
Japanese Patent JP6944643
Kind Code:
B2
Abstract:
To suppress the effect of heat generation that is attributable to charging/discharging of a secondary battery in a secondary battery charging/discharging test.SOLUTION: The present invention includes the steps of: preparing a thermostat bath 2; arranging a cooling device 10 for individually cooling a secondary battery 200 in the thermostat bath 2; arranging the secondary battery 200 in the thermostat bath 2 and connecting it to a circuit 4 that charges or discharges the secondary battery 200; setting the thermostat bath 2 to a predetermined temperature T1; and cooling the secondary battery 200 by the cooling device 10 arranged in the thermostat bath 2 so that when the secondary battery 200 generates heat or is anticipated to generate heat by being charged or discharged, a difference between the temperature T2 of the secondary battery 200 and the temperature T1 set to the thermostat bath 2 is reduced.SELECTED DRAWING: Figure 1
