Purpose and goal
Dynamically configurable battery systems for heavy vehicle propulsion are a promising concept with the potential to be developed into a commercial product, enabling more efficient battery use through individual control of battery modules. The project aims to prevent premature aging and battery failures by testing and demonstrating diagnostics and monitoring on a realistic pilot system. The project is a collaboration between the Vehicle Systems group at Linköping University and Scania CV AB.
Expected effects and result
The project will demonstrate the monitoring of dynamically configurable batteries. Outcomes include calibration methods for different battery architectures, analysis of diagnostic system fault sensitivity and response time, and verification of its ability to identify faults. A diagnostic demonstration of the pilot system will strengthen the concept´s credibility accelerate commercialization and contribute to sustainable, cost-effective battery solutions for fossil-free transportation.
Planned approach and implementation
A test plan will be developed based on a diagnosability analysis of the battery system to identify which faults and configurations will be tested. The faults will be implemented in the pilot plant and tests will be conducted according to agreed scenarios. Diagnostic algorithms will be calibrated with data from the fault-free operation and evaluated under normal conditions and during faults to ensure reliable results. The tests will be used to assess the diagnostic performance.
