<P>PROBLEM TO BE SOLVED: To provide a charge battery pack which flexibly deals with operation situations and prevents the deterioration of the workability when dealing with the operation situation. <P>SOLUTION: A charge battery pack 1 is used being attached to an electrically-driven device 2 and includes: multiple secondary battery blocks 5, connection routes electrically connecting the electrically-driven device 2 with the multiple secondary battery blocks 5, and switching means 9 switching the connection routes. The charge battery pack 1 is formed so that the switching means 9 automatically switches between the connection route where the multiple secondary battery blocks 5 are connected in parallel and the connection route where the multiple secondary battery blocks 5 are connected in series according to signals from the electrically-driven device 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
