Peterbilt enhances SmartAir no-idle system

Peterbilt has announced new enhancements to its SmartAir no-idle system with new auto-start technology that helps keep main and auxiliary batteries charged while running the air-conditioning system and using electric-powered devices.

The auto-start technology is available as a factory-installed option with Model 579s equipped with SmartAir and either a 72- or 80-in. sleeper. It is fully integrated with the vehicle’s electrical system to monitor battery charge levels and start the truck if the charge falls below a given threshold.

“SmartAir is a popular feature which allows customers to reduce fuel costs, comply with no-idle regulations and reduce their carbon footprint,” said Scott Newhouse, Peterbilt’s chief engineer. “It’s lightweight, compact and provides outstanding climate control in even the harshest conditions. The new auto-start technology complements the SmartAir system by helping ensure customers have the necessary power when they need it.”

Newhouse explained that auto-start monitors the charges of main and auxiliary batteries while the truck ignition is off. If the charges fall below a certain level, the system automatically starts the truck and runs the engine until batteries are sufficiently charged. The system performs several safety checks before cranking the engine. Additionally, interlocks ensure the system does not unexpectedly start.

SmartAir has a 7,500 BTU/hour cooling capacity and can operate for up to 10 hours on a single charge. As a factory-installed option, SmartAir is fully integrated into the existing HVAC system and utilizes existing ducting, and is controlled through an in-sleeper LCD display, the company said.

Geotab Connect, HDAW, TMC, Work Truck Week—It's been a busy start to the year here at Fleet Equipment. From tires to tech, connectivity to components, there's a list of topics that we've covered as companies look to deliver new products throughout this year, and beyond.

What have been some of the key themes so far? If you guessed EVs, you'd be right... sort of. While the race to the electrified future is always top of mind when talking about industry developments, this year, another big "E" took center stage, and that is efficiency. Many companies seem to be focusing on improving current generation technology to make sure fleets can get the most out of the money they've invested in their trucks.
