EPTAS Stack | OPTM Solutions

Overview

OPTM’s EPTAS is a Simulink-based e-powertrain application software that orchestrates all core powertrain functions of an electric vehicle, making real-time decisions that directly impact performance, efficiency, safety, and the overall driving experience through efficient diagnostics and energy management. Designed with a platform-agnostic architecture, EPTAS supports seamless integration with diverse hardware interfaces and sensors, allowing OEMs, Tier 1s, and mobility startups to customize and extend the base functionality with ease. Its modular codebase enables rapid adaptation to different drivetrain topologies, battery configurations, and control strategies without the need to start from scratch. Easily modify the application to run a truck or a 2W with minimal effort.
