Integrating Bidirectional Energy Systems in Software-Defined Vehicles: Impacts on Motion Control

This talk will explore how bidirectional energy capabilities in modern electric vehicles—specifically Vehicle-to-Load (V2L), Vehicle-to-Vehicle (V2V), Vehicle-to-Home (V2H), and Vehicle-to-Grid (V2G)—introduce critical system-level considerations that influence vehicle motion control within software-defined vehicle (SDV) architectures. As EVs evolve into multi-functional energy platforms, factors such as discharge modes, customer usage patterns, and system-level power management decisions increasingly interact with propulsion authority, inverter limits, battery state-of-charge constraints, and thermal operating envelopes. Presentation will discuss: Discharge Methodologies: Different discharging capability setup and how different approaches to energy discharge impact vehicle performance. Operating Scenarios: Real-world examples illustrating the interaction between energy allocation and motion capabilities. Shared Constraints: The necessity for motion-related functions to operate within electrical and thermal limits. Concluding with a forward-looking perspective, this talk will highlight how SDV architecture can enable coordinated control between motion capability, energy management, and bidirectional power systems in next-generation electrified vehicles.

Bio

Aravind Subramanian is a Senior Systems Engineer at General Motors in the Charging and BEV Energy Controls organization, where he develops control software for vehicle charging and bidirectional energy capabilities, including V2L, V2V, V2H, and V2G. With nearly a decade of experience in the EV and electrified powertrain domain across General Motors, Ford, and Roush, he has led the development, validation, and integration of battery and charging control systems for PHEV, BEV, and hybrid platforms. His work focuses on standards-based EV–EVSE communication, diagnostics, and safety logic to improve the reliability, interoperability, and grid integration of fast-charging infrastructure and bidirectional vehicles. He contributes to industry standardization and interoperability initiatives through CharIN and participates in ISO and SAE working groups related to EV charging and communication protocols. His broader interests include software-defined vehicle architectures, bidirectional energy systems, and the integration of electrification with vehicle-level energy management.
