Sweden's Scania, part of the Volkswagen Group via Traton, recently revealed a video of one of its electric semi truck crash tests, carried out to test the energy distribution surrounding the battery on impact.
"Electric truck crash testing is not the same as that of a truck with a combustion engine," Scania explains in the video description.
Ramming a Volkswagen Golf into a Scania
The test video — which can be viewed below — shows a Volkswagen Golf, without a front bumper cover, speeding up and crashing into the side of one of Scania's latest electric semis.
"The energy from the impact needs to be distributed and should spread throughout the structure surrounding the battery," the video description explains. "The desired state is that it deforms the plastic and distributes kinetic energy into less critical components."
Preparing for a real crash test is a lot of work, Scania says. Numerous digital simulations and months of precision planning are carried out before the real crash test takes place.
"The actual crash test is ultimately only to confirm that our calculations were accurate," says Test Engineer Jakob Leygraf at Scania R&D.
No visible battery cell damage
Scania's electric trucks use an oil-cooled permanent magnet electric motor peaking at 395 hp and 1,622 pound-feet of torque, with a continuous output of 308 hp and 958 pound-feet, The Drive reports.
With nine lithium-ion batteries on its larger trucks, allowing 300-kilowatt hours, Scania claims its trucks can reach up to 155 miles (249 km/h) on a full charge.
After the crash test shown in the video, the battery packs were disassembled. No damage to the cells was visible. Scania says it is still in the process of evaluating all of the data from the crash measurements and footage.
