It's a completely trivial difference compared to the damage that large trucks do. Damage to the road is proportional to the fourth power of weight per axle. Cars, and even SUVs, with or without a battery, are a rounding error. With that said, yes, there would still need to be some to ensure the roads exist at all, and for the damage that happens irrespective of usage (like from weather, shifting ground, etc).
