Embodiment Construction

[0061] The battery case of the present invention will be described in detail below with reference to the drawings.

[0062] Such as figure 1 As shown, the battery box 1 of this embodiment has a housing chamber 2 for detachably housing a plurality of battery modules 10, a control chamber 3, an intake side chamber 6a, and an exhaust side chamber 6b. A plate-shaped first member 20 on one side (here, the front side) of the storage chamber 2 and a second member 30 disposed on the other side (here, the rear side) of the housing chamber 2 . Furthermore, the battery module 10 is held in a state of being sandwiched between the first member 20 and the second member 30 , and is placed in the housing chamber 2 .

[0063] The storage room 2 is partitioned into a pair of front frame 1a, rear frame 1b, left and right frames 1c, 1e, middle frame 1d, and a plurality of vertical frames 1f connecting them. In this embodiment, a total of four battery modules 10 ( figure 1 Only the battery modu...

Abstract

The invention provides a battery box with easy battery module assembly and disassembly and good maintainability in the environment of the cooling air containing the dusts and a rail vehicle with the battery case. A battery box 1 comprises a plate-like first member 20 disposed on one side of a storage chamber 2 and a plate-like second member 30 disposed on the other side of the storage chamber 2 for supporting a plurality of battery modules 10 between the first member 20, wherein the first member 20 has feed ports 21 in airtight communication with inlets 11 opening at one end of battery modules 10 for introducing air therein, the second member 30 has discharge ports 31 for discharging the air introduced through the feed ports 21 into the interior of the battery modules 10 to the exterior, and at least one of the first member 20 or the second member 30 is attached in a detachable manner to one side or the other side of the storage chamber 2.

Description

technical field [0001] The present invention relates to a battery box composed of a plurality of battery modules for energy management, in particular to a suitable high-voltage, high-capacity battery box mounted on a hybrid railway vehicle and a battery box with the battery box railway vehicles. Background technique [0002] A secondary battery system composed of a plurality of high-output-density battery elements such as lithium-ion batteries and nickel-metal hydride batteries is widely used in industrial applications. In particular, in recent years, secondary battery systems with higher voltage and higher capacitance have been popularized as power storage systems for hybrid vehicles. [0003] On the other hand, in the field of railway vehicles, in order to save energy, a hybrid railway vehicle that supplies electric power to a motor is actively developed by combining a generator driven by a diesel engine and a secondary battery system. In a hybrid rail vehicle, by regene...
