PROBLEM TO BE SOLVED: To provide a battery pack, capable of accurately measuring respective voltages of a plurality of secondary batteries or battery groups even if one or more safety switches are formed between the plurality of secondary batteries, or the plurality of battery groups having a plurality of unit cells. SOLUTION: The battery pack comprises a plurality of secondary batteries B, one or more safety switches 200 connected between two adjacent secondary batteries of the plurality of secondary batteries, and a plurality of sensing wires W for measuring the respective voltages of the plurality of secondary batteries. The number of sensing wires is equal to the total of the number of secondary batteries and the number of safety switches plus 1. COPYRIGHT: (C)2009,JPO&INPIT |
