Volvo Trucks NA & UMN Extreme Weather Testing
Volvo Trucks North America is working with the University of Minnesota (UMN) to conduct extreme weather testing for its Class 8 VNR Electric model to analyze the impact of ambient temperature on a truck’s battery life. UMN has teamed up with Murphy Logistics Solutions (Murphy) to test the battery-electric trucks in Minnesota with cold winter temperatures and H-E-B Grocery Company (HEB) in Texas to test during periods of intense summer heat. The extreme weather testing project, which will demonstrate the capability of the Volvo VNR Electric using real-world fleet routes, is part of a Battery Efficiency for Sustainable Trucks (BEST) Project sponsored by the U.S. Department of Energy’s (DOE) Vehicle Technology Office.
The project will track the results of two Volvo VNR Electric engineering trucks with a six-battery configuration that are rated to provide up to 275 miles of range. Volvo Trucks is analyzing the battery-electric trucks’ performance on different routes in extreme temperatures with varying terrains and payload weights to better understand the challenges these factors present to help customers improve route planning and optimization.
Murphy and HEB will operate the battery-electric trucks on freight routes that exceed 250 miles in a day utilizing drivers in their fleets who have been trained by the Volvo Trucks electromobility team to utilize regenerative braking and other safe driving practices designed to maximize vehicle range. The VNR Electric trucks will leave the warehouse at the beginning of the day with a 100% state of charge (SOC) and will ideally return near empty (~10% SOC) at the end of their routes to take full advantage of useable energy in the battery.
Similar to battery-electric passenger cars, heavy-duty battery-electric trucks can experience range reductions during extreme temperatures due to battery chemistry where the chemical and physical reactions in the battery can occur more slowly, reducing the BEV’s range. To combat that, a dedicated Battery Thermal Management System (BTMS) is included with the Volvo VNR Electric model to manage and maintain the optimum battery temperature range. The BTMS is a dedicated heating and cooling system connected to the batteries with the purpose of avoiding the chemical reaction slow down or potential cell damage in extreme conditions. This in turn provides long life and excellent performance from the batteries under a variety of weather conditions that the vehicle encounters in real world conditions.
The other significant factor is the use of auxiliary power to either cool or warm the passenger cabin. If the ambient temperature is significantly above or below 70-71°F — the average temperature people keep their homes — the driver is more likely to turn on the heat or air conditioning, which draws energy from the battery.
In addition to the severe weather testing, UMN has developed an Intelligent Energy Management System (EMS) connected solution tool to help fleets understand how driving style can impact range, as well as how to take advantage of more energy efficient routing and decrease the cost and time required for on-route battery charging. The tool uses a machine learning-based algorithm to dynamically inform drivers about available range and minimum charging requirements, taking load and ambient conditions into consideration. The EMS also enables higher efficiency and longer range through advanced eco-route planning. To date, the EMS tool has helped Murphy and HEB achieve more than 20% increase in range.
Once the research project in both climates is complete, UMN will publish the results in a series of conference and journal papers, in addition to sharing information with U.S. DOE and Volvo Trucks in the form of a final project report.
The two Volvo VNR Electric trucks participating in the field tests are supported by the Volvo Trucks commercial support teams and are maintained and serviced by Nuss Truck & Equipment, the local Volvo Trucks Certified Electric Vehicle Dealership in Minneapolis, Minnesota. Volvo Trucks has a robust network of certified EV dealer partners across North America that have completed the required facility upgrades and rigorous training to service and maintain the Volvo VNR Electric model to ensure peak vehicle uptime, performance, and productivity.

StoreDot Increases Battery Performance
StoreDot, the pioneer of extreme fast charging (XFC) high energy battery solutions for electric vehicles, has obtained outstanding battery performance feedback for the first evaluation and integration A-Samples testing phase of its XFC electric vehicle battery cells.
The comprehensive testing programs took place over the past six months by 15 leading global automotive brand manufacturers from Europe, Asia, and the US, as well as several of StoreDot’s strategic ecosystem partners. Feedback from partners that have completed tests showed that the cells exceeded expectations, with those still conducting tests expected to report similar results.
The aim of the testing and evaluation programs was predominantly to replicate StoreDot’s unique extreme fast charging specifications based on its partners’ use case and test procedures. When the OEMs and partners replicated StoreDot’s results, they reached an energy density greater than 300Wh/kg, at a charging rate higher than 4C, achieving over 1000 consecutive XFC charging cycles.
The programs encompassed two main paths: The first included XFC datasheet and specification verification based on StoreDot’s rigorous testing procedures, and the second covered specific EV-OEM test protocols for critical performance and safety parameters relevant to their use cases.
The feedback received was overwhelmingly positive, surpassing StoreDot’s target specifications. Some OEM partners have already progressed to phase two of the testing programs, which involves the initiation of B-Samples programs tailored to their own form-factor and specific requirements, enabling future implementation in each OEM EV architecture.
Amir Tirosh, StoreDot COO: “We are hugely confident in our XFC technology – the ability to charge the cell from 10%-80% in just 10 minutes – based on our own rigorous testing procedures. However, receiving such positive feedback from global EV manufacturers gives us even more assurance in our groundbreaking product. Our partners are extremely pleased with the results of our battery cells, showcasing unprecedented energy density levels, and charging times that will prove to be a game-changer for the entire industry. The testing results confirm the value proposition that XFC is critical in eliminating range and charging anxiety, while at the same time empowering OEMs to design EVs with smaller pack sizes that can charge in minutes.
