Should Toyota’s research prove fruitful, the benefits are huge. Costs can be reduced by limiting battery capacity to match the actual driving range requirements. If a vehicle has a morning delivery route, for example, of around 100 miles, it doesn’t need more range. As such, it also will have a lower mass, and when it returns to HQ, a fresh battery pack can be swapped in during the driver’s lunch break.
In addition, the requirement for charging infrastructure will be reduced, and battery packs can be charged while the vehicles are out and about, reducing peak power demand. And who knows? Perhaps the research will prove so fruitful that we see swappable batteries come to vehicles like the Toyota bZ4X and others.
