Important results from the project
The project has developed embedded electronics and software for use in batteries for heavier vehicles or energy storage, so that the batteries become controllable. Two prototypes have been developed, where the first prototype focused on verifying the electronics and software, FlexiBESS. Here, goal fulfillment has been very good. The second prototype is prepared for vehicle integration, where some tests in a lab environment remain. These tests are planned to be performed in the fall of 2025.
Expected long term effects
The project demonstrates the possibility of dividing a larger battery into many smaller controllable parts, so that the parts of the battery can be used according to their remaining capacity, while the voltage and power flow of the battery system can be controlled. This can increase the lifespan of the battery cells included in a battery system, and make it easier to mix the old and new batteries, as well as cells with different chemistries, with low losses in the control electronics.
Approach and implementation
Scania has developed a modular, compact battery concept in collaboration with SEM, which was responsible for the distributed power electronics. The battery is designed to optimize the control capabilities and flexibility of the electronics while being mechanically adapted for heavier vehicles. The co-optimization has worked very well and enabled the demonstration of a modular expandable battery concept.
