GoKawiilResolvent and DTU Build Simulation App to Improve Volvo EV Truck Battery Welds
A consortium including Aurobay, Resolvent, DTU, Vinnova, Innovation Fund Denmark and Volvo Group Trucks Operations completed the LaserBATMAN project, which ran from May 2022 to May 2025. The project used multiscale simulation to study how laser welding affects battery pack robustness and lifetime, and Resolvent built a custom simulation app that lets Volvo's R&D team test battery lifetime performance.
GoKawiil's interpretation of the reporting above, not reported fact.
Battery lifetime remains a key barrier to making electric trucks viable for long-haul highway delivery, so tools that let engineers model manufacturing defects like weld quality before physical testing could shorten development cycles. The involvement of EU and Nordic public funding bodies alongside Volvo suggests this is viewed as a priority area for decarbonizing freight transport, though actual improvements in truck battery durability from this work are not yet detailed.
- LaserBATMAN ran from May 2022 to May 2025 with multiple European industry and academic partners.
- Resolvent developed a simulation app giving Volvo's R&D team an easier way to test battery lifetime performance.
- The project focused on laser welding in battery pack assembly as a factor influencing robustness and longevity.
