The invention relates to a nickel-hydrogen battery power supply system for a diesel locomotive. The nickel-hydrogen battery power supply system comprises a nickel-hydrogen storage battery pack and a power supply circuit, when the diesel engine is started, the nickel-hydrogen storage battery pack provides a starting power supply through the power supply circuit, so that the starting generator works as a series motor, and the diesel engine is dragged to an ignition rotating speed after speed change of the starting gearbox; meanwhile, control electricity is provided for other loads on the diesel locomotive; after the diesel engine is started, the nickel-metal hydride storage battery pack can provide a power supply through the power supply circuit and can also drive the starting generator to rotate through the gearbox, so that the starting generator works as a separately excited generator, and direct current is provided to supply power to the nickel-metal hydride system through the charging circuit. The lead-acid battery has dual characteristics of a battery and a capacitor, is long in service cycle life, and can solve the problem that a locomotive is difficult to start due to poor low-temperature performance of a lead-acid battery and the problem that a storage battery is easy to lack of electricity at low temperature; the weight is light and the volume space is small; modularized assembly is achieved, the construction workload is greatly reduced, and the working efficiency is improved.
