2 tons of refrigeration operating for one hour will only make 183 pounds of ice, or about 23 gallons.

What is the end goal now? Are we building an EV that regularly gets driven (in which case...

Tons per 24 hours, and only for the short time it takes to cool down. As mentioned, 1 ton is plenty for a fairly large RV.

For the batteries, a mere 4-5x per pound compared to ice which actually gets reduced to about 2.5x after derating the batteries. Doesn't seem like a huge improvement compared to the cost. On the...
