Abstract

A system is provided for cooling an energy storage system of a hybrid electric vehicle. The energy storage system includes at least one energy storage device. The system includes at least one inner casing configured to encapsulate at least one inner core of at least one respective energy storage device of the energy storage system. Additionally, the system includes at least one outer layer configured to surround the at least one inner casing. The system further includes an inner space positioned between the at least one inner casing and the at least one outer layer, where the inner space is configured to receive cooling fluid through at least one inlet in the outer layer.

Description

technical field [0001] The present invention relates to large battery applications, and more particularly to systems and methods for cooling large battery systems, such as energy storage systems for hybrid electric vehicles. Background technique [0002] A hybrid diesel electric vehicle, such as a hybrid diesel electric locomotive, for example, includes an energy storage system with several energy storage devices, ie batteries. These energy storage devices are typically used to store secondary electrical energy during a dynamic braking mode when the traction motors generate excess electrical energy that can be stored, or during an engine run mode when the locomotive engine generates excess electrical energy that can be stored. Each locomotive typically includes a number of energy storage devices, such as between ten and fifteen, where each energy storage device is a massive block consisting of several hundred individual cells grouped together, and each totals Weigh up to se...
