Mapping Range and Energy Consumption Estimation

Mauka Energy offers the batter-hybrid electric vehicle energy routing (BEVER) and forestry electric vehicle energy routing (FEVER) tools that accounts for heavy-duty trucks capable of regenerative braking. This tool allows operators of EVs to select the most energy efficient route to their destination and determine the maximum range of their vehicles.

Simulations on forest landscapes indicate that in road systems where empty logging trucks gain elevation and full trucks lose elevation while delivering their timber loads to lower elevation mills, regenerative braking can reduce energy transportation cost by over 30%.

Forest stands colored based on total transportation cost (kilojoules) for an empty Hybrid Class 8 Truck traveling from the Lewisburg Trailhead (node 101) to the harvest polygon and then traveling back loaded to Peavy Arboretum (Node 190).

Our Services

Landscape Level Digitization & EV range estimation

We offer high accuracy landscape level mapping and modeling to calculate and show range and energy cost for electric and hybrid vehicles using the FEVER tool

Cost Analysis

Our system allows for cost comparisons between EV and traditional diesel fleets. Our patented BEVER tool can show the effective cost saving in terms of energy and total operational cost.

Licensing & Training

The patented BEVER & FEVER technology is available for licensing. We offer training and support services to GIS analysis and automotive manufacturers and designers

  • John Sessions

    TECHINCAL ADVISOR

    Dr. Sessions, University Distinguished Professor Emeritus, has been involved in transportation operations and research for more than 40 years at Oregon State University. Previously, Dr. Sessions was harvesting manager of the world’s largest tropical forest plantation where he oversaw a fleet of over 300 company and contractor trucks. His research has been documented in more than 400 peer-reviewed publications and reports including the upcoming international book Forest Logistics. Dr. Sessions has authored a number of network-based software and truck simulation software. He chairs the examination team for professional registration in forest engineering for the State of Oregon. His accomplishments have been recognized with a number of awards, including the National Award in Forest Science by the Society of American Foresters and the Scientific Achievement Award by the International Union of Forest Research Organizations. Dr. Sessions serves as technical advisor for the development of the FEVER tool’s truck performance modeling.

Our Partnerships

  • Edison Motors

    Our partnership with Edison Motors aims to revolutionize the logging industry by introducing eco-friendly transportation solutions. Edison Motors is the leading expert in advanced forestry electric vehicle technology, and their prototype ELT L-Series ‘Topsy’ is the first hybrid electric vehicle built from the ground up to haul logs

  • McDonald Dunn Research Forest

    Mauka Energy has partnered with Oregon State University’s Research Forests to develop the FEVER tool. The McDonald and Dunn Research Forests are located a short 15 minute drive north of the OSU campus. Because of their close proximity to campus, these Forests are extensively used for university instruction and research. Managers apply several silvicultural themes - even-aged, two-aged, and multi-aged (plus mature forest reserves) across the entire McDonald and Dunn Forests, depending on specific objectives for each area. The Forest's recreation opportunities in close proximity to the Corvallis community result in over 155,000 non-motorized recreation visits each year.

  • OSU Advantage Accelerator

    Oregon State University’s Advantage Accelerator program and commercialization experts were crucial in securing the patent underpinning the BEVER and FEVER technology. The BEVER and FEVER tools and methodology arose out of research by David Hamilton at Oregon State University.

    In July 2023, OSU prepared and filed a United States non-provisional patent application to secure the core technology for the FEVER tool.

    In April 2024, OSU prepared and filed a United States non-provisional patent application to secure the core technology for the BEVER tool.

  • UBC's Alex Fraser Research Forest

    UBC’s Alex Fraser Research Forest is hosting research projects to help develop the FEVER tool. The Alex Fraser Research Forest is part of the Faculty of Forestry at the University of British Columbia. Situated on close to 10,000 hectares of crown forest in the Cariboo region of south-central British Columbia, it is one of two UBC Research Forests managed to create opportunities for research, education and demonstration of sustainable forest management.
