Software-Defined Power Interoperability for Cordless Tool Ecosystems
Run your tools on any compatible battery — safely.
VoltForge is a software-defined battery adapter that enables cross-ecosystem power tool compatibility using real-time regulation, typed compatibility models, embedded Rust control firmware, and safety-first design.
| Phase | Paper | Focus |
|---|---|---|
| 1 | Power Electronics | Buck/boost converter design, MOSFET switching, voltage regulation, transient analysis |
| 2 | Control Loop | PID/state-space regulation, stability analysis, load profile response |
| 3 | Thermal Management | Heat dissipation modeling, thermal protection, derating strategies |
| 4 | Firmware Control | Type-safe Rust embedded firmware, state machines, HIL testing |
| 5 | Synthesis RTOS | Unified real-time OS architecture composing all phases |
