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.

    本发明涉及一种内燃机车用镍氢电池供电系统,包括镍氢蓄电池组和供电电路;柴油机启动时,镍氢蓄电池组通过供电电路提供启动电源,使启动发电机作为串励电动机工作,通过启动变速箱变速后拖动柴油机至发火转速;同时为内燃机车上的其他负载提供控制用电;柴油机启动后,镍氢蓄电池组可以通过供电电路提供供电电源,也可以通过变速箱带动启动发电机旋转,使启动发电机作为他励发电机工作,提供直流电通过充电电路给镍氢系统供电。本发明兼有电池和电容双重特性,使用循环寿命长,能够解决铅酸电池低温性能差造成机车起机困难的问题和低温下蓄电池容易亏电的问题;重量轻、体积空间小;实现模块化组装,大大降低施工工作量,提高工作效率。
