Description

Shelving System for Testing Battery Modules
TECHNICAL FIELD
Aspects of the invention relate to a system for mounting battery modules within an environmental chamber. Particularly, but not exclusively, for testing battery modules for use in automotive traction batteries.
BACKGROUND
There has recently been increased interest in hybrid and electric vehicles. One of the challenges faced in the production of such vehicles is to improve the characteristics of the batteries used to power the traction motor (or traction motors). It is generally desirable for vehicle traction batteries to provide a high energy density, to be capable of rapid charging, and to be capable of providing a high peak power output. It is also essential that the thermal characteristics of vehicle batteries are such that overheating of the battery will not occur during any expected use case. Accordingly, rigorous testing of vehicle traction batteries is required.
A traction battery of an electric or hybrid vehicle typically comprises one or more battery modules, each module comprising a plurality of rechargeable cylindrical cells.
Testing of battery modules within environmental chambers has hitherto been a labour intensive process. The battery modules relatively heavy, so there is a risk of lifting injury if they are to be lifted manually into the environmental chamber. Alternatively, lifting equipment such as a fork lift truck can be used. However use of such lifting equipment typically introduces its own difficulties, for example relating to the provision of adequate space to manoeuvre the lifting equipment. Furthermore, it is desirable to maximise the number of battery modules that can be placed within an environmental chamber at any given time, so as to increase the testing throughput that can be achieved by a given facility.
It is an object of embodiments of the invention to at least mitigate one or more of the problems of the prior art.
SUMMARY OF THE INVENTION
According to an aspect of the invention for which protection is sought there is provided a system for mounting battery modules within an environmental chamber, the system comprising a shelving module and a tray module, the shelving module being sized to fit within the environmental chamber and comprising a first shelf located at a first level and comprising a first group of spaced apart channels and a second shelf located at a second level and comprising a second group of spaced apart channels, the tray module comprising a support surface arranged to support the battery module thereon, and a plurality of spaced apart bearing runners located underneath the support surface, wherein the bearing runners are arranged to run into the first group of spaced apart channels or the second group of spaced apart channels, such that the battery module may be received within the environmental chamber on the first shelf or the second shelf. Advantageously, such a system substantially eliminates the requirement to manually handle battery modules, and provides a convenience means of transferring battery modules into an environmental chamber.
In an embodiment, the shelving module further comprises a bulkhead connector for connecting power and/or coolant to the battery module.
In an embodiment, the support surface comprises adjustable supports, whereby the tray module is configured to support battery modules of different sizes. Advantageously, this makes the system more versatile. Optionally the adjustable supports are mounted on one or more bars, wherein the position of the adjustable supports along the bars can be adjusted so as to allow the tray module to support battery modules of different sizes.
In an embodiment, the bearing runners are ball bearing runners.
The system may further comprise a chamber lifting module, the chamber lifting module the chamber lifting module comprising a support surface having a third group of spaced apart channels located thereon and a lifting apparatus arranged to lift the support surface, wherein the bearing runners are arranged to run in the third group of spaced apart channels. Advantageously, the chamber lifting module facilitates easy transfer of battery modules into the environmental chamber.
Within the scope of this application it is expressly intended that the various aspects, embodiments, examples and alternatives set out in the preceding paragraphs, in the claims and/or in the following description and drawings, and in particular the individual features thereof, may be taken independently or in any combination. That is, all embodiments and/or features of any embodiment can be combined in any way and/or combination, unless such features are incompatible.

BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will now be described by way of example only, with reference to the accompanying figures, in which: Figure 1 shows a system for mounting battery modules within an environmental chamber in an embodiment of the present invention.
Figure 2 shows a shelving system in an environment of the present invention.
Figure 3 shows a tray module in an embodiment of the present invention.
Figure 4 shows a chamber lifting module in an environment of the present invention.
DETAILED DESCRIPTION
Figure 1 shows a system 1010 for mounting battery modules 1500 within an environmental chamber 1100. The system comprises a shelving module 1200 which is mounted within the environmental chamber 1100, lifting module 1400 and one or more tray modules 1300. The parts of the system will be described in more detail below with respecting figures 2 to 4.
Figure 2 shows a shelving module 1200 which is sized to fit within the environmental chamber 1100. As can be seen from Figures 1 and 2, the shelving module 1200 is placed within the environmental chamber 1100 on the bottom surface of the inside of the environmental chamber. The shelving module 1200 is secured in place within the environmental chamber 1100 by rails 1206, which are connected to the shelving module 1200 via telescopic arms 1204. Once the shelving module is placed within the environmental chamber, the length of the telescopic arms 1204 is increased so that the rails 1206 abut the upper surface of the environmental chamber, thereby preventing movement of the shelving module within the environmental chamber.
The shelving module comprises two shelves 1208A, 1208B, each shelf being provided with three spaced apart channels 1202. As will become apparent, the spaced apart channels allow for the tray modules 1300 to be easily slid onto the shelves 1208A, 1208B.
Although not visible in figure 2, each shelf of the shelving module 1200 is also provided with a bulkhead connector for providing quick connection of power and coolant to the battery modules.
Figure 3 shows a more detailed view of the tray module 1300. A support surface configured to support a battery module 1500 is provided by four spaced apart adjustable supports 1306 fixed to three bars 1308. The position of the supports 1306 along the bars 1308 can be adjusted so that the tray module can be used for battery modules of various different sizes. The bars 1308 are mounted on top of three spaced apart bearing runners 1302, the spacing between the bearing runners being equivalent to the spacing between the channels 1202 on the first and second shelves 1208A, 1208B. Each of the bearing runners 1302 is provided with two captive ball bearings 1304 which allow for the tray module 1300 to be easily slid within the channels 1202. Accordingly, the tray module allows for easy installation of battery modules onto the shelves 1208 of the shelving module 1200. Advantageously the arrangement of the adjustable supports 1306 attached to the bars 1308 mounted on the runners 1302 positions the battery module 1500, when mounted atop the adjustable supports 1306, so that the battery is exposed to the environment within the environment chamber. It will be appreciated that arrangements of fewer or more of each of the runners, bars and adjustable supports are within the scope of the invention.
Figure 4 shows two of the tray modules 1300 on a lifting system 1400. The lifting system 1400 comprises a support surface 1404 having three spaced apart channels 1402 mounted thereon. The spacing between the channels 1402 is equivalent to the spacing between the channels 1202 on the shelves 1208. Accordingly, the bearing runners 1302 are able to run within the channels 1402. The support surface 1404 is mounted on a scissor lift system (not clearly visible in the figure), which allows the height of the support surface 1404 to be adjusted such that it can be equal to the height of one of the shelves 1208 mounted within the environmental chamber 1100. The lifting system 1400 is also provided with wheels 1406, which allow the system to be manoeuvred between a location at which the battery modules are prepared and a location of the environmental chamber 1100.
The battery modules 1500 mounted on the tray modules 1300 can be easily slid into the environmental chamber 1100, by moving the lifting system 1400 so that it is adjacent to the environmental chamber with the channels 1402 on the support surface aligned with the channels 1202 on one of the shelves 1208, and the height of the support surface 1404 being equivalent to the height the shelf 1208. The tray modules can then be simply slid from the lifting system 1400 onto the shelf 1208, thereby installing the battery modules within the environmental chamber. Testing of the battery module within the environmental chamber can then commence after the bulkheads have been used to connect coolant and power to the battery modules.
During the process of transferring the training modules into the environmental chamber, the lifting module may be secured to the shelving system using one or more catches or locks which ensure correct alignment between the channels 1202 on the shelf on the channels 1402 on the lifting system.
Although the chamber lifting system 1400 shown in Figure 4 is wide enough to accommodate two battery modules mounted on respective tray modules 1300, the system according to the present invention could additionally or instead comprise a narrower lifting system capable of accommodating only one tray module. Although the ability to accommodate only one tray module would potentially increase the number of trips required to install all of the battery modules within the environmental chamber, it may be advantageous to provide a narrower chamber lifting system 1400 so as to ensure the chamber lifting system is able to comfortably pass between the location at which the battery modules are prepared and the location of the environmental chamber 1100. It will be understood that the present invention could additionally or instead comprise a wider lifting system capable of accommodating more than two tray modules.
The system according to the present invention may also comprise a static workbench having a support surface including spaced apart channels similar to the channels 1402 shown on the support surface 1404 of the lifting module. The tray modules and associated battery modules 1300 may then be prepared on the static workbench, and once preparation is complete they may be easily transferred onto the chamber lifting system 1400 for transfer into onto one of the shelves 1208.
All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
Each feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
The invention is not restricted to the details of any foregoing embodiments. The invention extends to any novel one, or any novel combination, of the features disclosed in this specification (including any accompanying claims, abstract and drawings), or to any novel one, or any novel combination, of the steps of any method or process so disclosed. The claims should not be construed to cover merely the foregoing embodiments, but also any embodiments which fall within the scope of the claims.
