That shift is changing the design of light trucks, as we detail in the ELM Mobility joint venture on page 50, and driving the move to cell-to-chassis architectures, discussed on page 32, for reduced vehicle weight. Both designs emphasise the safety requirements, from re-designing the ELM cab to the encapsulation and cooling of the battery cells in the chassis. Electrifying large trucks is also requiring new standards for safe, fast charging with megawatts of power that is changing the architecture of vehicles and the supporting charging systems, as we discuss on page 56. But this shift is not without its challenges. The innovation in the design of motors and cooling systems is detailed on pages 64 and 42, with the increase in performance providing designers with more options for higher power or reduced size that impinge on battery pack design and cooling options. And this trend is not confined to land. Huge battery packs are driving the largest cruise ships and ferries that will be fitted out later this year and in operation next year. These fully electric and hybrid vessels (Grid, page 6) are the result of cleansheet designs for e-mobility that clearly highlight a fundamental industry shift.
