Kenworth Advanced Charge Start System Now in Production

Kenworth has introduced into production advanced technology to enhance protection against battery drainage and a new inverter/charger option for easier battery recharging while parked.


The ultracapacitor-based Maxwell Engine Start Module (ESM) is a factory-installed option for new Kenworth T680s and T880s. The module provides dedicated power to start the truck and frees the truck’s standard batteries to focus on powering accessory devices, such as a laptop, microwave, refrigerator and television electronics, in addition to the truck’s electronics and lights. The ESM is designed to start an engine in temperatures as low as minus 40 degrees Fahrenheit to a high of 149 degrees Fahrenheit, even when the batteries have low voltage.

“Kenworth customers can benefit from the Engine Start Module option, which is a cost-effective way to help reduce downtime and maintenance costs caused by low voltage,” said Kurt Swihart, Kenworth marketing director. “The Engine Start Module has proven itself as a very capable solution for situations where starting reliability is critical.” Kenworth dealers offer ESM as an aftermarket solution, as well.


Also now in production is Kenworth’s new, enhanced 1,800-watt inverter that provides the convenience of AC power in the sleeper. “Inverters are popular as they utilize AC power versus DC to help efficiently operate appliances, entertainment systems and other devices in the sleeper,” said Swihart. “That’s a benefit to drivers, plus the Kenworth inverter can operate more systems and devices with better performance in handling high-amp loads.”
The Kenworth inverter also offers charging capability. “Plug the truck into shore power at a truck stop, at a terminal or at home, and run all your hotel loads while charging the batteries,” Swihart said. “In the sleeper, there is a control panel with on/off switching, plus battery status.”
The inverter is mounted on the rear wall in the sleeper storage compartment, which provides easy access to the toolbox and additional outlets through the toolbox door. The new inverter is optional for the Kenworth Idle Management System with the T680 76-inch sleeper, and charges the starter and idle management system batteries when plugged into shore power.
