To solve a problem in that supplying large electric current significantly depletes electrical current supply within an electrical storage device and degrades the electrical storage device and/or associated components.SOLUTION: In a vehicle 106, a locomotive propulsion system 200 includes traction motors 202A, 202B, a propulsion electrical storage device 204, an ancillary electrical storage device 206, and a controller 208. The propulsion electrical storage device is electrically connected to the traction motor via a propulsion circuit 214. The ancillary electrical storage device is electrically connected to the traction motor via an ancillary circuit 216. The controller directs the ancillary electrical storage device to supply electric current to the traction motor via the ancillary circuit to power the traction motor during an elevated demand period. At an end of the elevated demand period, the controller controls the ancillary circuit to stop conducting electric current from the ancillary electrical storage device and directs the propulsion electrical storage device to supply electric current to the traction motor via the propulsion circuit to power the traction motor.SELECTED DRAWING: Figure 2

    【課題】大きな電流を供給することは、蓄電装置内の電流供給を著しく減らし、蓄電装置および/または関連するコンポーネントを劣化させる。【解決手段】車両106において、機関車推進システム200は、主電動機202A、202B推力蓄電装置204、補助的な蓄電装置206及びコントローラ208を含む。推力蓄電装置は、推進回路214を介して主電動機に電気的に連結する。補助的な蓄電装置は、補助的な回路216を介して主電動機と電気的に連結する。コントローラは、高い需要期間の際中に主電動機に動力を供給するために、補助的な回路を介して主電動機に電流を供給するよう補助的な蓄電装置に命令する。高い需要期間の終わりに、コントローラは、補助的な蓄電装置からの電流の伝導を中止するために補助的な回路を制御し、かつ、主電動機に動力を供給するために推進回路を介して主電動機に電流を供給するよう推力蓄電装置に命令する。【選択図】図2
