Proterra doesn't scale,
Proterra doesn't scale, though. Proterra requires an expensive infrastructure of $600,000 per charging station per route, BYD only requires a slow-charger at the depot for $6,000. What's more, BYD buses drive the cost for its battery technology down dramatically, while Proterra's SCiB technology is specialist use; BYD LiMnFePO4 can potentially power cars, taxis, grid storage, and more.
