Ricardo reveals battery breakthrough

Ricardo and QinetiQ have claimed to have made significant breakthroughs in the development of affordable high-performance battery technology for hybrid and electric vehicles.

Coming off the back of a two-year partnership codenamed the Reduced cost Li-Ion (RED-LION) project, the core aim for the two UK organizations was to develop an alternative Li-Ion cell chemistry that could be integrated within an HEV using a bespoke battery management system. Following completion of the project, the partners have announced that a battery pack using QinetiQ’s new and innovative iron sulphide-based cell chemistry and Ricardo’s latest advanced battery management system, has demonstrated both cost and weight reductions compared to Ricardo’s Efficient-C full hybrid vehicle.

To prove the potential of the alternative cell chemistry, the RED-LION project, which has been part funded by the Department for Transport under the UK Energy Saving Trust Low Carbon R&D program, set out to replace the battery pack used in the Efficient-C prototype HEV with one using new cells capable of demonstrating suitable material cycle life, capacity, specific energy, rate capability and safety. Custom cells were manufactured and packaged within a bespoke battery pack incorporating many novel features.

Ricardo designed the overall battery pack to directly replace the existing unit, developing a new battery management system to manage the iron sulfer chemistry. Meanwhile the prototype cells were designed and manufactured by QinetiQ, and during tests, the cells have shown to deliver a cycle life of over 1,000 cycles at a limited depth of discharge. Such a high charge/discharge rate capability means that the cell design would make it suited to both HEVs and low-range PHEVs. Comparing the performance of the prototype high rate cells with the cells originally used in the Efficient-C HEV, a 20% reduction in weight on a Wh/kg basis was achieved by the partners.
