High-capacity battery system for locomotive

Abstract

The invention relates to a high-capacity battery system for a locomotive. The high-capacity battery system for the locomotive comprises a battery assembly and a fusing protection assembly, and the safety performance of the battery system is improved by the fusing protection assembly; and the fusing protection assembly comprises a system anode fuse, a battery pack fuse, a module connecting copper bar, a bus copper bar, a fuse wire group and a battery cell protector; and fusing current values of the fusing protection assembly are arranged as follows: the system anode fuse < the battery pack fuse < the module connecting copper bar < the bus copper bar < the fuse wire < the battery cell protector. The structure is simple, the positive electrode high-voltage box, the negative electrode high-voltage box, the control battery system box body, the power battery assembly and the heat guarantee system are placed in a centralized mode, an integral mounting frame is adopted, mounting is easy and convenient, and the integration degree is high; and a six-layer fusing safety design is adopted, and fusing current values allowed to pass through by different parts in the fusing protection assembly are different, so that fusing current protection of each level is realized.

Description

technical field [0001] The invention relates to the technical field of locomotive battery systems, in particular to a large-capacity battery system for locomotives. Background technique [0002] At present, the use of power battery systems in the rail transit industry is still in the initial stage, and the energy of the battery systems used is relatively low. Most of them are used for auxiliary power supply. With the requirements of national policies, for the original simple use of high-power diesel engines for traction operations, It will consume a large amount of fuel and produce a large amount of polluting gas, which will pollute the atmosphere and affect the living environment. Therefore, there is an urgent demand for energy-saving and environmentally friendly diesel locomotives. The power battery system with large capacity and high power has begun to be used to replace diesel engines to reduce fuel consumption. To achieve the purpose of energy saving and environmental p...

[0002] At present, the use of power battery systems in the rail transit industry is still in the initial stage, and the energy of the battery systems used is relatively low. Most of them are used for auxiliary power supply. With the requirements of national policies, for the original simple use of high-power diesel engines for traction operations, It will consume a large amount of fuel and produce a large amount of polluting gas, which will pollute the atmosphere and affect the living environment. Therefore, there is an urgent demand for energy-saving and environmentally friendly diesel locomotives. The power battery system with large capacity and high power has begun to be used to replace diesel engines to reduce fuel consumption. Realize the purpose of energy saving and environmental protection

[0003] At present, the power battery system used in the automobile industry and the rail transit industry has a small capacity, and the environmental conditions used are also different, so it cannot be used directly
