Solid State Battery Smart & Structural Modular Integration into Vehicle through Flexible Module to Chassis Design

S4MILE project aims to support the large-scale introduction of electric vehicles by simplifying the vehicle structure and integrating the next-generation solid-state cells into the vehicle structure based on a disruptive and innovative ‘virtual’ module-to-chassis concept (VM2C) based on large structural ALU casting and composite unibodies. The size of the permanently installed battery is reduced using a novel swappable module design to increase the gravimetric and volumetric energy density of the unit in a safe and robust design. The solid-state technology, coupled with advanced thermal and pressure management systems, enables fast charging and long-range based on a reconfigurable battery management system (BMS), which facilitates maintainability, reparability and second life and ensures modularity and scalability of the design applicable to a range of small to medium size vehicles through a safe and efficient communication and operation with the vehicle controller. Advanced battery models based on a battery passport coupled with a thermal management system in a digital twin of the battery will ensure optimal operation and life and range extension while ensuring safety in all operating conditions. S4MILE builds upon large experience and prior projects to meet outstanding results capable of boosting the EU landscape in EVs and related sectors.
