A virtual representation of a physical battery asset used for real-time monitoring, virtual cell design, and fleet-wide intelligence. It consists of three components:
- Physical Twin – the actual asset
- Digital Representation – the virtual model
- Data Model – the real-time connection for data flow
Digital Twin of a Battery Module
- The capacity and resistance differences of cells amplify the inhomogeneity at a system level and results in accelerated aging and degradation.
- For the module design, where many cells are in parallel, the BMS typically does not have access to individual cell currents and temperatures.
- We aim to predict current, state of health and temperature of each cell in the module (or pack) via modelling the interaction between cell and busbar and weld quality.
