The invention is applicable to the technical field of high-speed railways, and provides an emergency charging method for power shortage of a storage battery of a motor train unit. The emergency charging method comprises the following steps of: charging a storage battery of a power shortage unit train by using a charger of a non-power-shortage unit train; or after a storage battery of the non-power-shortage unit train is used for leading electricity to a charger of the power shortage unit train, charging the storage battery of the power shortage unit train by using the charger of the power shortage unit train. According to the emergency charging method for the power shortage of the storage battery of the motor train unit provided by the embodiment of the invention, the non-power-shortage unit train is used for charging the power shortage unit train, so that the power shortage unit train can be stably charged, and the limitation of a traditional method can be avoided, thereby ensuring that the power shortage unit train safely and efficiently completes an emergency charging process.

    本发明适用于高速铁路技术领域,提供了一种动车组蓄电池亏电的应急充电方法,其包括以下步骤:利用未亏电动车组的充电机向亏电动车组的蓄电池进行充电;或者利用未亏电动车组的蓄电池向亏电动车组的充电机进行引电后,再通过亏电动车组的充电机对亏电动车组的蓄电池进行充电。本发明实施例提供的动车组蓄电池亏电的应急充电方法,利用未亏电动车组对亏电动车组进行充电,既能对亏电动车组进行稳定的充电,而且也能避免传统方法的局限性,以保证亏电动车组安全、高效的完成应急充电过程。
