Hoymiles launches 22 kW V2X

Hoymiles has added a new piece to its residential energy lineup: a 22 kW DC vehicle-to-everything charger that links an electric vehicle to the company’s HiOne all-in-one battery energy storage system. The company announced the product on September 7 from Hangzhou, China, saying the charger is meant to extend a home setup built around solar and storage into electric mobility. The device is designed for bidirectional power flow, so electricity can move from the home to the vehicle and back again. In Hoymiles’ framing, that turns the car battery into another controllable asset inside the household energy system. ### What exactly did Hoymiles launch? The product is a DC V2X charger listed by Hoymiles as the HiOne-22VD-G3. Hoymiles says it works with the HiOne All-in-One BESS, a home storage platform that combines inverter, battery and energy management functions in one system. The company’s HiOne product page now presents the V2X module alongside the inverter, modular battery, gateway and monitoring platform as part of a single residential stack.

The company described the charger as the component that extends its home energy ecosystem into electric mobility. ### How does the charger fit into the HiOne home system? Hoymiles says the charger is meant to let solar generation, battery storage, EVs and the grid operate as one integrated system. (hoymiles.com) In practical terms, that means the EV is not treated only as a load to be charged, but also as a source of stored electricity that can interact with the rest of the home setup. (hoymiles.com) The HiOne platform is the anchor product around that setup. Hoymiles introduced HiOne in February 2026 and described it as its first all-in-one residential battery energy storage system. The company said at the time that the launch marked the start of wider HiOne deployment in Europe through distributor partnerships. (prnewswire.com) ### What are the key technical details? The charger’s headline specification is 22 kW of DC bi-directional charging power. A Hoymiles product document says it supports a 200-1000 Vdc charging voltage range, a spec the company says is intended to cover current and future EVs. Hoymiles also says the charger is designed for broad vehicle compatibility. (hoymiles.com) In syndicated versions of the release, the company said the unit supports 95% of mainstream EVs. ### Why is bidirectional charging the central feature here? Hoymiles says the charger’s bidirectional capability allows an EV to become “an active additional energy resource for the home.” That is the operating logic behind V2H and broader V2X functions: energy can be stored in the vehicle when power is abundant and drawn back when the home needs it. (w3oss.hoymiles.com) (de.advfn.com) The company also says the charger is built as a standalone unit that can be installed beside a parking space, rather than requiring the battery system itself to sit in the same location. That gives installers more flexibility in how they place the charger and the HiOne cabinet around a house. (eqs-news.com) ### Where does this leave Hoymiles’ product lineup? Hoymiles already sold AC EV chargers that could connect with its storage inverter in a combined PV, storage and EV charging setup. The new V2X product shifts that offer toward bidirectional DC charging tied directly to the HiOne platform. On September 8, the company’s newsroom and product pages were carrying the launch materials for the HiOne-22VD-G3 and the broader HiOne system. (de.advfn.com) Hoymiles’ next step, based on those materials, is commercial rollout of the charger as part of the same integrated residential package that includes the inverter, modular battery, gateway and monitoring platform.
