<p>The present invention is directed to a locomotive comprising energy storage units such as batteries, a prime energy source (1001), such as a diesel engine, and an energy conversion device (1002), such as a generator. The locomotive comprises one or more of the following features: a separate chopp er circuit (1010) for each traction motor (1008); energy storage units (1003) that can be switched from parallel to series electrical connections, a fluid - activated anti-lock brake system (1009), a controller (1015) operable to control separately and independently each axle(1006)/traction motor (1008), and a controller (1051) operable to control automatically a speed of the locomotive. The present invention includes an integrated system for monitoring, controlling and optimizing an electrically powered locomotive using a combination of sensors and software to provide feedback that optimiz es power train efficiency and individual drive axle (1006) performance for a locomotive that utilizes one of several possible electrical energy storage systems to provide the tractive power. The net result is a locomotive that h as an integrated system of control over all aspects of the locomotive power tra in including control over individual drive axles (1006), especially during acceleration, braking and non-synchronous wheel slip.</p> |
