A system-level framework for validating high-voltage EV powertrain software — before hardware exists.
A virtual Hardware-in-the-Loop platform designed to simulate, validate, and stress-test high-voltage EV systems entirely in software.
EVO vHIL integrates production-intent embedded firmware with an Android Automotive OS control daemon, connected over a virtualized CAN network — all executing without a single physical component.
The result is a complete, closed-loop powertrain simulation where engineers can inject fault conditions, test thermal runaway responses, and validate DC Fast Charging sequences that would be physically dangerous or impossible on a real bench.
The control system must survive the failure of the traction system.
Redundancy applied to consumer EV architecture — a dedicated 4S LV pack ensures control plane continuity through any traction failure.
This document describes the EVO architecture at a system and interface level. Certain subsystems — including LV energy management and CCS charging control — are intentionally documented using externally observable guarantees rather than internal implementation details. This approach preserves proprietary design elements while ensuring all safety-critical behaviors and system-level invariants are clearly defined.
