Electric storage is one of the load-bearing problems in automotive electrification. Cell chemistries, pack designs, performance envelopes, and lifetime targets pull in opposite directions — every battery programme is a trade-off between range, reliability, weight, safety and durability. DDSPLM partners with Siemens Digital Industries Software to deliver simulation and engineering services that span the full battery stack, from electrode microstructure to vehicle-level behaviour.
The pressures shaping battery engineering
- Energy density vs. safety. Higher-density chemistries raise the stakes on thermal runaway, so thermal and abuse simulation moves early in the design.
- Fast charging stresses everything. Charge rates that were exotic a few years ago are now table stakes — and they punish weak thermal paths mercilessly.
- Manufacturing scale-up is its own discipline. A cell that works on the bench has to survive gigafactory-rate production and assembly tolerances.
- Localisation in India. PLI-backed cell and pack manufacturing is ramping fast, and new entrants need a validated engineering chain from day one.
Capabilities
- Cell-level electrochemistry and micro-structure modelling to link chemistry choices to real-world performance.
- Module and pack design with coupled thermal, mechanical and CFD analysis.
- System-level simulation with Simcenter Amesim — battery + powertrain + vehicle.
- Charging and thermal-management strategies evaluated in virtual prototypes before hardware exists.
Design exploration before hardware
To stay ahead in the innovation race, engineers need to predict the outcome of design changes on real-world performance fast. We deploy simulation chains that let teams cost-effectively evaluate cells, modules and packs under expected operating and abuse conditions — long before a physical prototype lands on the bench, and long before a costly field failure can.
