Trucking fleets may just plug into an electrical outlet to refuel in the not-so-distant future. Jay Sandler, Vice President of Commercial Products for Workhorse Custom Chassis, a truck chassis manufacturer, thinks medium-duty work trucks of all kinds powered mainly by electricity are only five to 10 years away.

Recently hybrid truck options have come to the fore for heavy-duty pick up and delivery chores, as well as for an array of construction, maintenance, and service trucks, while hybrid electric cars have been in the news for some time. A special display of hybrid trucks was included in a recent trade show sponsored by the National Truck Equipment Association. At the same show, an overflow crowd was attracted to a special hybrid truck seminar sponsored by International Truck and Engine Corporation.

With environmental concerns coupled to rising fuel and engine costs, the search for alternative fuels and other sources of power has never been more heated in the trucking industry. Major parcel delivery fleets, such as UPS, FedEx, Purolator of Canada, and USPS have put a variety of hybrids and alternative fuel vehicles into experimental use. For most fleets, however, hybrid technology remains too expensive despite such advantages as a 30 to 50 percent reduction in fuel costs, less maintenance, less noise and fumes (helpful in residential areas), and the hybrid’s environmental benefit.

Events are making hybrids more palatable. “2007 emission requirements have upped the cost of diesel engines from $4,000 to $10,000 more than 2006 models,” says Sandler. “And more requirements and price increases are coming in 2010.” Then add unpredictable but mostly higher fuel costs into the equation and you have fleets pressing engine and chassis manufacturers to find better solutions.

Sandler has been in the trucking industry for 30-years and his company has been one of those in the forefront of providing such solutions. “Workhorse and other manufacturers of trucks and truck components have been working with hybrid technology for some years now,” Sandler stated. “A number of fleets and companies have been very proactive in looking at multiple solutions that will contribute to a cleaner environment.”

Workhorse recently developed two hybrid electric versions of its walk-in truck (step van) chassis for two different parcel delivery companies, Purolator of Canada and UPS. Because these were custom built, neither version is cheap. However, with a few more developments, both hold promise, Sandler mentioned.

“In the past year we engineered two totally different hybrid solutions and there’s more we’re looking at,” said Sandler. “From a price standpoint, as orders go up, production costs will come down. But advancements in technology will also be (important), particularly in terms of battery storage capacity. And I don’t think we’re far away from that.”

“At present, the hybrid battery pack is the most expensive component we add to make a hybrid electric truck,” Sandler explains. “With more efficient battery storage a fleet of ‘plug in trucks’ would work quite well.”

Such trucks, according to Sandler, would “fuel up” by plugging into an electrical outlet of whatever the configured voltage was. Cost-effectiveness would be increased by doing this at night, say between midnight and 5 a.m., which is when the power grid has the least amount of demand and power might be purchased more cheaply.

A fleet would buy their “fuel” from a power company. Preferably this would also be “clean” power, as power companies develop nuclear plants, natural gas systems, solar power, geothermal energy, and other “green” ways of generating electricity. In any case, the power would be from something more efficient than an internal combustion engine.

That fleet would be an electric-powered vehicle for most of the day. A small gas or diesel engine would provide supplemental energy, if needed. For a walk-in truck, there would probably be a 2 or 2 ½ liter engine that would run the generator, said Sandler. When the battery charge drops to a certain level, the generator automatically starts and recharges the batteries. At the end of a typical day, 70 percent of the truck’s energy may have come from the overnight plug-in and 30 percent from the onboard generator, putting regular fuel consumption at 50 to 60 miles per gallon or more for stop-and-go driving.

As there would be a lot of stop and go driving serving their local routes, pick up and delivery fleets of all kinds would likely lead the way in this hybrid revolution, suggested Sandler. “Parcel delivery fleets have been the leaders in experimenting with hybrid electric trucks so far, because in the near term that is where hybrid electric technology can provide the greatest cost savings. I expect bakeries, textile rental operations, and other local delivery fleets will also be early adopters of this technology.”

“I think this technology will quickly evolve in the next five to 10 years,” says Sandler. “The gas or diesel powertrain will be very different. These future hybrids will have similar horsepower and torque, as today’s trucks. They will be quieter and, for the most part, odorless in terms of combustion fumes. The smaller engines they do have will be cleaner-burning and, as they are reduced to a peripheral part of the new power equation, they will significantly reduce the need for oil sources, foreign or domestic. Theses trucks will be a big leap forward in reducing the emissions everyone is concerned about. It will be the most significant change in automotive power we will see in our lifetime.”

Sandler has seen many changes in the industry. Prior to Workhorse he held executive positions at Bering Truck Corporation and Meritor Automotive, formerly Rockwell Automotive, where he began his career as an engineer. “Fleets need to come to grips with the fact that the electric truck is no longer something to dismiss as science fiction,” said Sandler. “Just like cars, hybrid electric trucks are here now, and may well be everywhere tomorrow.”
