The older (Austin?) introductory presentation (2017-2018) of the semi spoke of ridiculously low 7¢/kWh electricity availability (which even in Texas is a ridiculously low rate). I can't help but think that when you tack-on the added expenses of:
I'm finding it hard to imagine:
1. Site acquisition and leasing; 2. Permitting; 3. Design; 4. Trenching and installation; 5. Charger manufacturer; 6. Ongoing maintenance; 7. Added feature of a giant battery to feed the semi batteries
will be cost-competitive with current diesel prices.
a) that 7¢ was even realistic for grid power backing in 2018; b) that the enumerated costs above;
Lastly, if its 30 minutes at 1,000 kW to reach 70% state of charge, then the battery is 500 kWh < x < 714 kWh. I'm thinking my math must be wrong somewhere... But if this is the ballpark, then this is going to be one expensive battery.
