Vertexcom Technologies, a smart charging communication chip design company, has announced support for ISO 15118-20 Bidirectional Power Transfer (BPT), also known as Vehicle-to-Grid (V2G) transfer, in its chipsets.

Vertexcom’s HomePlug GreenPHY SECC chipset MSE1021+MSEX24-i and EVCC chipset MSE1022+MSEX25-i support the implementation of ISO 15118-20 BPT. Drivers can save or make money by using electricity stored in their EV when rates are high and recharging when rates are low. The Combined Charging System (CCS) standard allows direct bidirectional access to the EV or its battery via the charging station, without the need to install V2G hardware in the car. CCS-enabled DC wall boxes can charge and discharge EVs at home and are compatible with high-power charging infrastructure elsewhere.

BPT is a feature of the ISO 15118-20, “second-generation network layer and application layer requirements” published in April 2022. 

“Drivers using BPT can provide service to the grid for stabilization, to the home for self-consumption, to buildings such as company offices and to tools or consumer devices,” the company said. “The goal is to transform EVs into mobile energy storage systems.”
