The Nautilus is an all-electric shipping cargo port drayage tractor with a 60,000-pound max payload and a 30-60 mi range, depending on payload and battery configuration. Balqon offers two versions of the Nautilus: the E20 and E30. The E20 contains 140kWh of flooded deep-cycle lead acid batteries and has a top speed of 25mph. The E30 contains 160kWh of flooded deep-cycle lead acid batteries and has a top speed of 40mph. Both versions of the Nautilus are powered by a 100 HP, 230V AC motor with a proprietary 240kW liquid-cooled controller. Using Aerovironment’s Posicharge fast charging system, the Nautilus can recharge from 0% to 60% in 1 hr (E30), or to 80% SOC in 3.5 hr (E20). 25 Nautiluses are now active in the Port of LA from an AQMD and Port of LA Grand. Balqon is currently testing using Li-ion batteries in the Nautilus.
