Hoymiles launches 22 kW V2X charger

Hoymiles has added a new piece to its home-energy lineup: a 22 kW bidirectional DC charger built for vehicle-to-home and vehicle-to-grid use. The company said on September 7 that the charger is designed to work with its HiOne All-in-One battery energy storage system, extending the same residential setup from solar and storage into EV charging.

(w3oss.hoymiles.com) Hoymiles is pitching the EV not just as a load that consumes electricity, but as another controllable asset inside the house energy stack, alongside rooftop solar, stationary storage and the grid. (hoymiles.com) ### Why is the charger DC and bidirectional instead of a standard home EV charger? Hoymiles says the charger is a DC V2X unit, which means it handles direct-current charging and discharging rather than relying on the vehicle’s onboard charger for AC/DC conversion. In its launch material, the company said that setup allows direct DC power flow between photovoltaic generation, battery storage and the EV, while cutting conversion losses. (prnewswire.com) The technical point is straightforward: a conventional AC home charger mainly pushes power one way, from the house to the car. A bidirectional DC charger is meant to do both directions, so the vehicle battery can also send power back to the home or, where allowed, toward the grid. (prnewswire.com) Hoymiles says that gives homeowners another flexible energy source during outages, peak-price periods or solar-heavy daytime generation. ### How does it fit with the HiOne system Hoymiles is already selling? Hoymiles lists the V2X charger as part of the HiOne platform, which combines inverter, battery and energy management system functions in one residential package. The company’s HiOne product page shows the V2X module alongside modular batteries, a gateway for whole-home backup and the S-miles Cloud monitoring platform. (prnewswire.com) The company says that architecture is meant to coordinate several energy flows at once: solar generation, stationary storage, EV charging and backup power. In practice, the charger is being sold as one more power-electronics module inside a managed home system rather than as a generic wallbox for any installation.

A product document also lists a 200-1000 Vdc charging-voltage range, which Hoymiles says is intended to support both current and future electric vehicles. (hoymiles.com) Hoymiles also says the charger supports “efficient power flow” among the EV, the home and the grid. That language is important because the sales pitch is not only faster charging; it is coordinated energy management, where a parked EV can operate as reserve capacity inside the household system. (prnewswire.com) ### Does this mean any EV owner can immediately use vehicle-to-home or vehicle-to-grid? Hoymiles describes the charger as V2X-capable, but real-world use still depends on more than the charger itself. Vehicle compatibility, local interconnection rules, utility programs and site-specific installation requirements all affect whether a homeowner can use vehicle-to-home or vehicle-to-grid functions in practice. (w3oss.hoymiles.com) Hoymiles’ materials focus on the charger and its integration with HiOne rather than naming supported vehicle models or market-by-market grid programs. That leaves the launch positioned as an ecosystem expansion first. (w3oss.hoymiles.com) The company is saying it now has a residential package that can tie together solar, battery storage, backup and EV energy flows under one platform. ### What should readers watch next? September 7 and September 8 were the key publication dates for Hoymiles’ launch materials across its newsroom, product pages and syndicated release distribution. The next concrete step is likely to come from installation guidance, regional availability details and any list of compatible vehicles or supported grid-use cases that Hoymiles publishes for the HiOne-22VD-G3 charger.
