Munich-based tech company EcoG has presented an ISO-compliant bidirectional charging solution which follows charging standards association CharIN’s guidelines.
EcoG plans to unveil a pre-integrated reference design for bidirectional charging in addition to EcoG Charge Controllers. Together with partner Infineon, a power semiconductor manufacturer, EcoG is developing a starter kit with an integrated 22 kW converter and controller.
As EcoG sees it, a lack of compatibility between charging stations and EVs is an obstacle to more widespread implementation of V2H/V2G. EcoG has tested its V2G/BiDi solution with vehicle manufacturers in accordance with the new ISO 15118-20 bidirectional power transfer (BPT) standard, as well as the BPT Application Guide from CharIN.
As a core member of CharIN, EcoG has played an important role in the application description for the ISO standard. EcoG is also supporting harmonization and alignment between the ISO 15118 and SAE J2847 charging standards for V2G. This should lead to better scalability, compatibility and interoperability. EcoG’s software is designed to support all V2G-capable vehicles—including those still under development.
“The fact that bidirectional charging actually works according to ISO 15118-20 BPT is a major step forward,” said Xi Zhang, EcoG’s Director of E-mobility. “This allows the technology to be applied to the mass market, as customers can now be sure that their wallbox can communicate with any V2G-enabled vehicle in the field.”
“V2G as the standardized feature is essential for broad adoption of this technology,” added co-founder and CEO Jörg Heuer. “Vehicle manufacturers are including the bidirectional wallbox as part of their offerings. EcoG provides the V2G technology in the form of a starter kit to charger manufacturers to enable products with short lead time to market, and to OEMs for interoperability testing.”
