Low Cost Auxillary Power Unit (LowCAP)
In plain English
AI plain-English summaryTata Motors, Ashwoods Automotive, and the University of Bath are building a low-cost, lightweight auxiliary power unit for electric vehicles that can be mass-produced globally. The problem is straightforward: electric vehicles need a backup generator to extend their range, but existing auxiliary power units are too expensive and heavy for mass-market cars. This project tackles that gap by combining Tata’s low-cost internal combustion engine with Ashwoods’ low-cost electric motor technology, developed in earlier government-funded projects. The team will design, model, and test a fully integrated unit built from sustainable materials. If successful, the LowCAP unit could become a standard component in Tata Motors’ own vehicles and be sold to other global carmakers. That would lower the cost of range-extended electric vehicles, making them more accessible to ordinary drivers. The intellectual property and manufacturing would remain in the UK, tying British engineering into one of the cheapest engines on the market. The project is commercially driven from day one, with no fundamental science component—it is a direct push to create a product for the global automotive supply chain.
