Recent years has seen a lot of research into techniques for manufacturing battery packs for a variety of different electric vehicles.
However, there are still gaps in industry knowledge in this area, such as data related to the electrical and mechanical performance as a function of different joining techniques used in battery pack manufacture. Literature in this area tends towards a top level view rather than delivering details of specific process data.
Of course, electric vehicle battery packs have also raised some environmental concerns over material waste and disposal. This has opened a route for concepts for disassembly and recycling to be investigated, including engagement with industry to identify battery pack design trends. There are also gaps in current standards and a need to assess areas where standards could be beneficial for industry, whether for manufacture, performance testing or inspection.
TWI Ltd is currently investigating all of these issues as part of a research project that aims to reduce failure rates in battery packs, optimise designs, understand disassembly and recycling requirements, and deliver quality assurance methodologies and protocols.
