BMW Developing New Battery With 30% More Range That Costs 50% Less | Carscoops carscoops
Theis currently under development at the BMW Group Battery Cell Centre of Excellence in Munich, Germany and adopts a cylindrical shape. The shape of the cell will allow BMW to ditch the current prismatic cells it currently configures in modules that are bolted together to create a pack and instead, allow for a new cell-to-pack design to be adopted.
The new design will allow the battery pack to be mounted directly into the vehicle’s frame. This won’t just improve chassis stiffness and ride quality but will contribute to a cost saving of 50 per cent for the battery pack. Charging the battery from 10 to 80 per cent will also take 30 per cent less time than BMW’s current EV models.notes that the new cell uses more nickel and silicon while using less cobalt.
“Energy density is much higher than before,” BMW’s Simon Erhard said. “You can put more cells into the battery pack. With Gen 6, we are integrating cylindrical battery cells straight into the vehicle. It’s now part of the body. The main challenge is to achieve the right compromise between stiffness and flexibility. The most integrated [design] would be where the vehicle floor is the upper part of the battery pack.
