If you end the day with less than a full battery charge, a 13-kW onboard charger provides a plug-in option to charge the truck overnight. e hybrid drive system manages the power from the fuel cell to and from the batteries, as well as the trac- tion motors and other components such as the electrified power steering and the brake's air compressor. e truck will make about 3,800 lb.- . of torque but is limited to save wear and tear on a rear end that is designed to handle roughly half that amount. Shiing is handled through an Eaton Fuller 18-speed gearbox that's been heavily customized to feature four speeds. It uses the same range and splitter, which provides a low-end ratio of about 4:38 and a direct top end. e lower ratio gives the truck ex- cellent startability and enough torque to start up a 20 percent grade, while the top end gives the truck enough power to maintain 30 mph up a 6 per- cent grade and well above the average drayage speed of about 20 mph. Stephan Olsen, Kenworth's director of product planning, says the batteries themselves are about 2,000 pounds. e battery management platform, high-voltage cable, coolant lines, enclosure and mounting add about another 1,500 pounds. All that adds up to the ZECT tipping the scales at about 22,000 pounds, about 3 tons more than a similarly-equipped die- sel-powered T680. "A lot of that comes from the batteries, some of that comes from the cooling system, and some of that comes from the hydrogen tanks," Lindgren says. Olsen says Kenworth testing has shown the hydrogen truck "performs equally as well as, if not better than, current diesel trucks on the market." From my brief time behind the wheel, I would agree. Beyond the fuel cell itself, much of the T680's equipment is stock – in- cluding the suspension and Spicer D40-170P (5.38) rear end – and the truck performed like you would ex- pect a T680 to perform. e ZECT is expected to log only about 50 miles per day, but the SoCal ports and Kenworth's ZECT will play an important role in validating hydro- gen's role in trucking.
