Abstract

A battery pack charging system includes a battery pack comprising a plurality of battery cells; a charging device connected to both electrodes of the battery pack to supply a charging current to the battery pack; a switch connected between the battery pack and the charging device to allow or block a flow of the charging current; and a current blocking member mechanically connected to the switch and configured to turn off the switch by causing a bending deformation when a potential difference formed between both electrodes of the battery pack is equal to or greater than a reference value.
