Kenworth is now producing 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.
