AI Enabled - Increased Battery Life and Safety

BMSTAR™️ combines highly accurate models of the battery with Artificial Intelligence and advanced estimation methods, to ensure accurate and reliable dataon the battery state for optimised battery life and safety.

AI Based Functions

  • Battery Cell Diagnosis:
    • Analyzing leading indicators enables diagnosis of battery cell issues months in advance.
    • Sophisticated data augmentation techniques to support training of machine learning models.
    • Models are able to run in real time on the edge (for in-vehicle application) and in the cloud (for large scale data analysis)
  • Remaining Useful Life:
    • Estimates the remaining time until the end of useful life
    • Can be used for both cloud-based fleet data analysis and on-board the vehicle as part of the BMS
    • Guides OEMs and their cell suppliers on the real-life fleet performance of batteries.
