Abstract
This paper presents an experimental demonstration of a basic bidirectional energy transfer consistent with the Vehicle-to-Everything (V2X) concept, using a commercial Battery Management System (BMS) not originally intended for automotive applications. A 14-series (14S) lithium-ion battery pack integrated with a 48 V BMS and a bidirectional inverter is experimentally evaluated under low-power operating conditions. The study focuses on practical system integration, protection behavior, and cell balancing functionality using minimal laboratory equipment. The results show that essential BMS functions are sufficient to support controlled bidirectional energy flow at low power levels, highlighting both the feasibility and limitations of low-cost BMS-based V2X experimental setups.
