Supported by a $870,000 grant from the Australian Renewable Energy Agency, this project is analysing the performance of eighteen leading batteries, comparing major lithium-ion battery brands to existing and advanced lead-acid battery technologies, as well as novel a zinc-bromide flow battery and an aqueous hybrid ion battery.
The project commenced in 2015 and is ongoing until 2020. The purpose of the project is to verify claims made by manufacturers about performance, integration, and installation of battery packs, and to disseminate the results to the public. To achieve this ITP is independently testing the performance of each battery side by side in hot daytime and cool overnight temperatures, similar to what they would be expected to face in real-world conditions. Testing takes place in a climate-controlled enclosure at the Canberra Institute of Technology.
As the batteries are cycled they lose the ability to store as much energy as when they were new. The key objective of the three year test is therefore to measure the batteries’ decrease in storage capacity over time and with energy throughput. The project seeks to provide independent performance data so people can make informed investment decisions. The project work includes:
- designing and building a battery test centre at the Sustainable Skills Training Hub at the Canberra Institute of Technology.
- testing the batteries by cycling (charging and discharging) several times per day, albeit within the manufacturers’ specifications, in order to produce informative test results within three years.
- publishing detailed comparative analysis of the test results every six months describing the technical performance and cost-effectiveness of each battery type/brand.
