Abstract
A battery pack includes a plurality of batteries; a circuit unit for controlling charging and discharging operations of the plurality of batteries; a case for containing the plurality of batteries and the circuit unit, and comprising an assembly of at least two sub-cases; and a submersion checking unit formed on a coupling portion between the at least two sub-cases. By using the battery pack, it is possible to rapidly cope with the submersion by easily checking the submersion of the battery pack, and to easily find the cause of functional deterioration or a malfunction.
