A semi weighs between 10,000 and 25,000 lb. A semi's ICE engine weighs around 3,000lb.
I don't work in the industry. I just observe three things:
1) the weight variance of a semi encompasses the amount imputed to the battery
2) 3,000lb of weight can be saved by not having a diesel engine plus another 2,000lb not having fuel. (Both of which will be in the total gross weight of the semi) some of which will of course be replaced by electric motors.
3) it's a speculative weight. It might also not weigh that much. Might is doing a lot of heavy lifting.
A fourth point: trucks routinely travel partly empty because of weight distribution issues. Not every TEU is full.
Logistics is fascinating. TCO is the closest most computer scientists get to "how can owning a Mac be cheaper than owning a Windows PC" but logistics does this almost every sum. Weight and carry capacity may not be the sole deciding factor here when a semi is worth $500k and has a 2nd hand value and is a finance decision with tail costs and operation costs.
