PROBLEM TO BE SOLVED: To provide a storage battery capable of responding to a request for a large amount power supply while ensuring a high reliability.SOLUTION: The storage battery includes: a battery group in which plural battery cells are connected to each other in series; a charge/discharge control FET which is connected to the low potential side of the battery group, and which has at least a pair of N channel MOSFETs connected to a source terminal in a back-to-back manner. The drive control section outputs a drive control signal which is generated on the basis of the potential level of the source terminal to a gate terminal of each of the N channel MOSFETs constituting the charge/discharge control FET. |
