A New Approach to Car Batteries Is About to Transform EVs
If you want to build an EV with better range, slapping in a larger battery to provide that range is not necessarily the solution. You would then have to increase the size of the brakes to make them capable of stopping the heavier car, and because of the bigger brakes you now need bigger wheels, and the weight of all those items would require a stronger structure. This is what car designers call the “weight spiral,” and the problem with batteries is that they require you to lug around dead weight just to power the vehicle.
But what if you could integrate the battery into the structure of the car so that the cells could serve the dual purpose of powering the vehicle and serving as its skeleton? That is exactly what Tesla and Chinese companies such as BYD and CATL are working on. The new structural designs coming out of these companies stand to not only change the way EVs are produced but increase vehicle ranges while decreasing manufacturing costs.
