I don't think we have the battery power density to power an 80,000 lb (~36,200 kg) truck at 65mph for 11 hours as allowed by the DOT Hours of Service Rules and Regulations (though I believe a 30 minute break is required after 8 hours, and the 11 hours of driving has to be within a 14 hour window, so some recharging stops may still work within those limits).
