For OTR trucks, you have to factor in the battery degradation. A OTR truck easily gets to 1 million miles on an engine. Often times significantly more, and then its only a rebuild, not a replacement. While electricity is much cheaper than diesel, battery replacement cost amortization is a real thing to include in the accounting. I haven't done an OTR, but I did do amortization for a Ford Lightning. While a "battery fill up" is $2-3. The replacement battery is $30k iirc. That's $3000/yr in costs assuming 10 year lifetime. At that rate, its $62/wk in battery amortization. So, you're really spending $62+3/wk in "energy". That's still less than a tank ($90-100 at current prices), but the savings is significantly less than originally anticipated.
