[0063] The control circuit (100) can supply the remaining power of the battery (B) to the cooling device (30) based on identifying the closure of the door (20). Since the battery (B) may not be cooled if the cooling device (30) is operated while the door (20) is open, it is preferable to operate the cooling device (30) while the door (20) is closed.
[0064] The control circuit (100) can control the cooling device (30) to maintain the temperature of the battery (B) below a critical temperature. The critical temperature can be set in various ways depending on the design. If the temperature of the battery (B) detected by the temperature sensor (60) is higher than the critical temperature, the control circuit (100) can control the operation of the cooling device (30) to increase the cooling performance of the cooling device (30). By maintaining the temperature of the battery (B) below the critical temperature, fire and explosion of the battery (B) can be prevented during transport.

When the external charger (50) is connected to the charging target, the external charger (50) can transmit an electrical signal to the control circuit (100) through the charger connector (14). The control circuit (100) can identify the connection between the external charger (50) and the charging target based on the electrical signal transmitted from the external charger (50). Based on identifying the connection between the external charger (50) and the charging target, the control circuit (100) can supply at least a portion of the remaining power of the battery (B) housed in the case (10) to the charging target.

[0071] The battery carrier (1) can control the cooling device (30) to maintain the temperature of the battery (B) below a critical temperature. The critical temperature can be set differently depending on the design. If the temperature of the battery (B) detected by the temperature sensor (60) is higher than the critical temperature, the battery carrier (1) can control the operation of the cooling device (30) to increase the cooling performance of the cooling device (30). By maintaining the temperature of the battery (B) below the critical temperature, fire and explosion of the battery (B) can be prevented during transport.
