Further, the surplus electric power not used for driving the electric heater 55a is charged to the battery 2, and the charge amount of the battery 2 gradually increases. Further, after time t2, since the temperature of the adsorption unit 55 is maintained at a constant temperature, CO 2 is desorbed from the adsorption unit 55 at a substantially constant rate, so that the desorbed CO ₂ is at a constant rate. It is taken out through the take-out hose 31 and the CO ₂ recovery amount is reduced at a substantially constant rate.

It will increase. Further, when the drive of the electric heater 55a is stopped, all the electric power supplied from the external power source is charged to the battery 2, so that the charge amount of the battery 2 increases rapidly.

At time t4, the power supply to the battery 2 is stopped according to the charging plan. By following each plan, charging of the battery 2 is basically completed at the timing of this time t4.
