Embodiment 1

[0033] The embodiment is basically as figure 1 As shown: this embodiment provides a high-power hybrid locomotive integrated power battery system, which is applied to a high-power hybrid locomotive with a loading capacity greater than 1000kWh; it includes two power battery devices 1, two power battery devices 1 are installed side by side on the vehicle frame, and each power battery device 1 is equipped with a chiller 2, and the two power battery devices 1 are arranged in parallel, so that when one of the power battery devices 1 fails, the hybrid locomotive still can function normally; specifically, as figure 2 As shown, each power battery device 1 has a first chamber 20 and a second chamber 21 arranged side by side, and the first chamber 20 and the second chamber 21 are divided and arranged with a battery compartment 22 and an equipment compartment 23 , and the battery compartment 22 and the equipment compartment 23 in the first chamber 20 and the second chamber 21 are arrang...

Embodiment 2

[0039] Embodiment 2 is basically the same as Embodiment 1, the difference is: please combine figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides an integrated power battery system for a high-power hybrid electric locomotive, which is fully considered in combination with the fact that the power battery pack cannot bear a large load and needs to be easy to install and maintain. The installation is designed as a drawer structure; specifically, a slide rail composition 11 is provided in the battery room 3, and the slide rail composition 11 includes a slide rail 15 and a slide rail 16, and the slide rail 16 is welded on the steel structure 13 of the battery room, and the slide rail 15 is welded with the battery mounting plate 10 arranged at the bottom of the battery pack 9, so that the battery pack 9 can be pulled out from the side of the battery chamber 3 along with the battery mounting plate 10. The structural design and installation method are simple, safe and...

Abstract

The invention discloses an integrated power battery system of a high-power hybrid power locomotive, and relates to the technical field of rail transit. The system comprises two power battery devices,and each power battery device is provided with a water chilling unit. Each power battery device is provided with a first chamber and a second chamber which are arranged side by side. Each of the two chambers is divided into a battery compartment and an equipment compartment, and the battery compartment and the equipment compartment in the two chambers are obliquely and symmetrically arranged. A plurality of layers of battery chambers for accommodating power battery packs and a cooling liquid pipeline system communicated with the water chilling unit are arranged in the battery compartment. By implementing the technical scheme, the technical problems of long production cycle and high cost of the existing integrated power battery system can be effectively solved, so that the production cycleof the power battery system is shortened and the manufacturing cost of the power battery system is reduced through reasonable integrated layout of the power battery packs; and meanwhile, the temperature uniformity of the battery packs can be effectively ensured through the configured cooling liquid pipeline system, and the practicability is very good in practice.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an integrated power battery system for a high-power hybrid locomotive. Background technique [0002] As the main energy storage component of hybrid electric locomotive, battery pack is a key component of hybrid electric locomotive, and its performance and service life will affect the performance of the whole vehicle. At present, the power battery packs commonly used in the market are specially designed and manufactured for the automotive industry, and their loading capacity is mostly around 200kWh. The main characteristics of this battery pack are: the surface structure has a poor bearing capacity, but its sealing performance is good. However, the above-mentioned battery packs are applied to high-power hybrid locomotives with a capacity greater than 1000kWh, and are usually designed jointly by the OEM and the battery factory based on the integration method of layered stackin...
