PROBLEM TO BE SOLVED: To provide a battery pack that hinders breakage in a second connection circuit and also hinders a cost increase, and to provide a power source system including the same.SOLUTION: A battery pack comprises: a first connection circuit that connects a storage battery and a rotary electric machine; a second connection circuit that connects the storage battery and the rotary electric machine and is lower in electric current resistance than the first connection circuit; a control section that controls each of the first connection circuit and the second connection circuit; and a sensor section that detects a state of the first connection circuit. In a case where a sensor value exceeds a first threshold value, the control section limits required output of the rotary electric machine. In a case where a sensor value exceeds a second threshold, the control section opens the first connection circuit and, at the same time, closes the second connection circuit, thereby electrically connecting the storage battery and the rotary electric machine via the second connection circuit.SELECTED DRAWING: Figure 13
【課題】第2接続回路で損傷が生じることが抑制され、なおかつコストの増大が抑制された電池パック、および、それを含む電源システムを提供する。【解決手段】蓄電池と回転電機とを接続する第1接続回路と、蓄電池と回転電機とを接続する、第1接続回路よりも耐電流性の低い第2接続回路と、第1接続回路と第2接続回路それぞれを制御する制御部と、第1接続回路の状態を検出するセンサ部と、を有し、制御部は、センサ値が第1閾値を超えた場合、回転電機の要求出力を制限し、センサ値が第2閾値を超えた場合、第1接続回路を開状態にしつつ、第2接続回路を閉状態にすることで、第2接続回路を介して蓄電池と回転電機とを電気的に接続する。【選択図】図13
