PowerX EV Charging Stations Now Support High-Voltage Charging

TOKYO, JAPAN --- PowerX, Inc. (Head Office: Tamano City, Okayama Prefecture; Director, President and CEO: Masahiro Ito; Securities Code: 485A) has upgraded its existing EV charging station in Ariake, Tokyo to support high-voltage charging, starting today. The upgrade raises the station's maximum output to 240 kW. PowerX plans to extend the upgrade to approximately 20 locations by the end of 2026, followed by its stations nationwide.

The upgrade involves partial modifications to the cables, charging connectors, and software of the existing "Hypercharger," PowerX's battery-integrated ultra-fast EV charging system. Once upgraded, the system supports a maximum voltage of 1,000 V and delivers up to 240 kW when a single connector is in use.* The system is equipped with a large-capacity 358 kWh battery and delivers high-output charging on a low-voltage grid connection. This capability remains unchanged following the upgrade. Drivers of conventional 400 V vehicles can continue to use the stations as before.

The upgrade also includes new charging connectors and cables. Lighter connectors and more flexible cables make the charging cable easier to handle and improve overall usability.

In recent years, premium brands have led the introduction of the latest EV models equipped with high-voltage systems, and their rollout in the Japanese market is expected to accelerate. This upgrade allows these vehicles to charge at their full potential. Drivers stopping by during a long-distance trip can charge in the time it takes for a short break, greatly reducing the stress of en-route charging.

PowerX will continue to contribute to the wider adoption of EVs in Japan and the realization of a carbon-neutral society by advancing and expanding its charging infrastructure.

^{*Actual charging output, voltage, and current may vary depending on the temperature and state of charge of the vehicle's battery, as well as limits on power received from the grid.}
