RelGen Hybrid Charging Solution

Blackburn Energy RelGen® solution captures wasted mechanical motion and converts it to energy that can be used to power your no-idle system or other accessories. It is an onboard hybrid charging solution that creates electricity from the rotation of the driveshaft providing additional power for your no-idle system - allowing you to stay comfortable longer. It charges faster and more fully than any other system on the market. Get peak performance even during extreme conditions when getting a good night's rest is a challenge. More rested drivers are more alert and effective. Add extra batteries with the RelGen Performance Pack and get extra power for the no-idle system and other sleeper cab appliances. Improved up-time and no idling.

Fastest Charge on the Market

RelGen charges the auxiliary batteries faster than anything on the market. Charge 4 AGM batteries from zero to 100% in under 4 hours. Better still, add the the RelGen Performance Pack and let RelGen charge 8 AGM batteries in under 6 hours.

RelGen charges while the truck is driving, day or night, in any kind of weather making sure the batteries are healthy and perform at their best. Fully charged, healthy batteries significantly extend the run time of the electric HVAC system such as Bergstrom's No-Idle solutions. Use RelGen to augment charging of the truck batteries, extending the use of hotel loads without idling the engine.
