I think EV sales will be pulled forwards in advance of the credit going away. There will be a plunge in sales immediately after expiration, then sales will recover. One thing we don't know is how manufacturers will respond to the loss of the credit. They still need to become profitable on EV sales because, no mistake about it, EV is the future. So they're still scaling up production of batteries in order to drive down costs.
Guess what still has a large production-based incentive post O3B:
battery cell production. LFP batteries can be used for other purposes, such as both grid and residential storage. I anticipate that a portion of the lost credit will be absorbed by the manufacturers. I'm sure they were inflating their prices already in response to the credit, and even with per-unit losses, they need the money to continue expanding cell production. In addition, there are newer, lower-cost chemistries, such as
Lithium-Sulfur, that may become
commercially available in the next few years. The manufacturers just need to get production adequately scaled.
