The XE20 is equipped with a high-efficiency 230V AC induction motor coupled directly to an Allison 4-speed transmission; the 240 kW liquid cooled drive technology provides the highest low-end torque in its class, according to Balqon. The XE20 has a range of more than 94 miles (151 km) unloaded, and a range of 50 miles (80 km) loaded on a single charge.

A 324 Volt, 140 kWh Li-ion battery pack is charged by a standard 20 kW charger; an 80 kW multi-vehicle charger is optional. Four charging ports are standard, with a priority smart charge algorithm based on the vehicle state of charge.

Field demonstrations conducted at both a large beverage distribution warehouse and an industrial manufacturing facility showed lower energy consumption over competitive diesel powered vehicles operated in similar environments. The Autocar Xspotter design results from Autocar’s extensive experience in numerous severe duty vocational truck applications to develop a more technologically advanced and modern yard tractor, with numerous safety, visibility, and durability advantages.

Autocar’s advanced yard tractor design, combined with Balqon’s latest lithium-ion battery power technology, makes the Nautilus XE20 the flagship of our product line. We believe true ergonomics begins with a clean environment and low noise in the cab for the operator that spends forty plus hours a week operating these vehicles.

In February 2009, Balqon Corp. began production of the E30, an all-electric, heavy-duty drayage truck capable of hauling 30-ton shipping containers in and around the San Pedro Bay, California port complex. Designed specifically for short-haul or drayage operations, the E30 can pull a 60,000-pound cargo container at a top speed of 40 mph, and has a range between 30 to 60 miles per battery charge.
