Volvo Vans North America is working with the College of Minnesota (UMN) to conduct excessive climate testing on its Class 8 VNR Electrical mannequin. The analysis trials goal to research the affect of ambient temperature on a truck’s battery life. UMN has teamed up with Murphy Logistics Options to check the battery-electric vehicles in Minnesota with chilly winter temperatures and H-E-B Grocery Firm in Texas to check during times of intense summer time warmth. The acute climate testing challenge, which can show the aptitude of the Volvo VNR Electrical utilizing real-world fleet routes, is a part of a Battery Effectivity for Sustainable Vans (BEST) Mission sponsored by the U.S. Division of Power’s (DOE) Automobile Know-how Workplace.

The challenge will observe the outcomes of two Volvo VNR Electrical engineering vehicles with a six-battery configuration rated to offer as much as 275 miles of vary. Volvo is analyzing the battery-electric vehicles’ efficiency on completely different routes in excessive temperatures with various terrains and payload weights to higher perceive the challenges these components current to assist prospects enhance route planning and optimization.

Murphy and HEB will function the battery-electric vehicles on freight routes that exceed 250 miles in a day using drivers of their fleets who’ve been educated by the Volvo Vans electromobility staff to make the most of regenerative braking and different protected driving practices designed to maximise car vary. The VNR Electrical vehicles will go away the warehouse at first of the day with a 100% state of cost (SOC) and can ideally return close to empty (~10% SOC) on the finish of their routes to take full benefit of useable vitality within the battery.

“Volvo Vans’ key to success is at all times aiming to enhance the enterprise worth of our vehicles for our prospects and persevering with to develop a constructive affect on the whole value of possession for the Volvo VNR Electrical vehicles,” mentioned Keith Brandis, vp of system options and partnerships for Volvo Group. “This analysis challenge is a essential step to making sure the effectivity and reliability of Class 8 battery-electric vehicles whatever the environmental components. The outcomes of this testing might be anticipated to bolster fleets’ confidence within the Volvo VNR Electrical vehicles’ reliability and efficiency in all climate circumstances whereas nonetheless offering the creature comforts for drivers.”

Devoted Environmental Management Methods

Just like battery-electric passenger vehicles, heavy-duty battery-electric vehicles can expertise vary reductions throughout excessive temperatures resulting from battery chemistry the place the chemical and bodily reactions within the battery can happen extra slowly, lowering the BEV’s vary. To fight that, a devoted Battery Thermal Administration System (BTMS) is included with the Volvo VNR Electrical mannequin to handle and preserve the optimum battery temperature vary. The BTMS is a devoted heating and cooling system related to the batteries with the aim of avoiding chemical response decelerate or potential cell injury in excessive circumstances. This in flip supplies lengthy life and wonderful efficiency from the batteries beneath quite a lot of climate circumstances that the car encounters in actual world circumstances.

The opposite important issue the exams will take a look at is using auxiliary energy to both cool or heat the passenger cabin. If the ambient temperature is considerably above or beneath 70-71°F — the typical temperature folks hold their properties — the driving force is extra prone to activate the warmth or air-con, which pulls vitality from the battery. 

Good Power Administration

Along with the extreme climate testing, UMN has developed an Clever Power Administration System (EMS) related resolution software to assist fleets perceive how driving fashion can affect vary, in addition to tips on how to benefit from extra vitality environment friendly routing and reduce the price and time required for on-route battery charging. The software makes use of a machine learning-based algorithm to dynamically inform drivers about out there vary and minimal charging necessities, taking load and ambient circumstances into consideration. The EMS additionally allows greater effectivity and longer vary by way of superior eco-route planning. Up to now, the EMS software has helped Murphy and HEB obtain greater than 20% improve in vary.

“Collaborating on analysis tasks that can have a direct affect on the viability of battery-electric vehicles in excessive climate supplies an incredible alternative for our college and college students to not solely achieve perception into the function that analysis and growth performs in trade however make an actual distinction in advancing sustainable transportation,” mentioned Dr. William Northrop,  Professor of Mechanical Engineering and director of the Thomas E. Murphy Engine Analysis Laboratory on the College of Minnesota – Twin Cities. “Most testing prior to now has been in a lab setting however now we’re working with two fleets to enhance real-world route effectivity and driver productiveness to validate our knowledge and software program. We’re excited to judge that knowledge for future purposes and assist Volvo Vans’ prospects really feel assured in deploying these zero-tailpipe emission vehicles in much more areas the place they will enhance fleet sustainability and native air high quality.”

As soon as the analysis challenge in each climates is full, UMN will publish the leads to a collection of convention and journal papers, along with sharing data with U.S. DOE and Volvo Vans within the type of a remaining challenge report. 

The 2 Volvo VNR Electrical vehicles taking part within the discipline exams are supported by the Volvo Vans business help groups and are maintained and serviced by Nuss Truck & Tools, the native Volvo Vans Licensed Electrical Automobile Dealership in Minneapolis, Minnesota. Volvo Vans has a sturdy community of licensed EV supplier companions throughout North America which have accomplished the required facility upgrades and rigorous coaching to service and preserve the Volvo VNR Electrical mannequin to make sure peak car uptime, efficiency, and productiveness.
