Embodiment Construction

[0046] Hereinafter, the battery module of the present invention will be described in detail with reference to the drawings.

[0047] figure 1 A perspective view showing a basic structure of a battery module according to an embodiment of the present invention. figure 2 for figure 1 The A-A' profile. Such as figure 1 and figure 2 As shown, in the case 1117 of the battery module 1110 of this embodiment, a plurality of parallel battery cells 1111 are accommodated. exist figure 1 Among them, the battery cells 1111 are a total of 48 cells stacked in two layers in the vertical direction, in two rows in the short side direction of the frame body, and in 12 rows in the long side direction of the frame body. On the basis of the group structure, there is a certain gap between each monomer and it is arranged in a square.

[0048] Openings 1112 for exposing most of the side surfaces of the battery cells 1111 to be housed are provided on a pair of side portions of the housing 1...

Abstract

The invention provides a battery module and a railway vehicle, wherein the structure of the battery module (1110) can be switched easily between a draft structure and an enclosed structure in response to the specifications of a system, and a high-performance cooling structure making use of the respective structures is enabled regardless of which cooling structure is selected. A package of batterymodules (1110) in which multiple battery cells (1111) are arranged in parallel has openings (1112) formed on a pair of side panels of the package throughwhich the side walls of the battery cells 1111are exposed. Further, either cooling ducts (1118) for letting ambient cooling air flow therethrough or cover plates (1115) for sealing the package of the battery modules (1110) are selectively attached to openings (1112). The cover plates (1115) have heat absorbing blocks (1113) disposed on the inner side thereof for thermally coming into contact with the side walls of the battery cells (1111), and radiating fins (1114) disposed on the outer side thereof.

Description

technical field [0001] The present invention relates to a plurality of battery modules for energy management and a battery box for accommodating them, and further relates to a railway vehicle equipped with an appropriate high-voltage, large-capacity battery box mounted on a hybrid railway vehicle. Background technique [0002] A secondary battery system composed of a plurality of high-power-density battery cells such as lithium-ion batteries or nickel-metal hydride batteries is widely used in industrial applications. In particular, secondary battery systems that have been increased in voltage and increased in capacity in recent years have begun to spread as power storage systems for hybrid vehicles. [0003] Correspondingly, in the field of railway vehicles, for the purpose of saving energy, the development of hybrid railway vehicles in which a generator driven by a diesel engine cooperates with a secondary battery system to supply electric power to a motor is actively progr...
