Portuguese charging technology company i-charging has introduced the AiO 500, a new all-in-one direct current fast charger designed to deliver up to 500 kW of charging power from a compact standalone unit.
The charging system is capable of operating at up to 1,000 volts and features two charging connectors with dynamic power-sharing capabilities, allowing available power to be allocated between two vehicles in real time.
According to i-charging, the AiO 500 is intended for motorway corridors, fuel stations and urban environments where charging demand is high but available space is limited.
The company plans to begin deliveries in selected European markets by the end of 2026, followed by North America in the first quarter of 2027. Deployment in markets with additional metrology requirements, including Germany, is expected at a later stage.
Dynamic Power Distribution
The AiO 500 incorporates i-charging’s proprietary power management technology, enabling the system to distribute charging power between connected vehicles in increments of 100 kW.
The company said power allocation is adjusted continuously based on the charging requirements of each vehicle.
“When two vehicles are connected, power is allocated based on what each can receive at that moment. If one vehicle requires higher power than the other, the system adjusts accordingly.”
According to i-charging, the approach is designed to maximize utilization of installed charging capacity while reducing charging times for users.
Multiple Connector Options
The charger can be configured with different charging standards, including CCS, NACS and GB/T connectors.
Customers also have the option of combining two charging standards within a single unit, such as CCS and NACS, allowing the system to support a wider range of electric vehicles.
The AiO 500 is available in two versions. The standard configuration supports charging currents of up to 500 amperes, while an optional liquid-cooled cable version supports up to 800 amperes.
Targeting Commercial Vehicle Charging
i-charging said the liquid-cooled configuration is intended to support heavy-duty vehicle applications, including freight transport, coaches and commercial fleets.
“Commercial and heavy-duty vehicles require higher sustained current over longer periods than standard cables can reliably deliver. With liquid-cooled cables, the AiO 500 is suited to freight, coach and heavy transport operations alongside passenger vehicle charging, from a single compact unit.”
The charging station features a 32-inch touchscreen interface, contactless payment functionality and optional bank card payment terminals.
Additional features include support for Plug&Charge, Autocharge and both OCPP 1.6 and OCPP 2.0.1 communication protocols. Connectivity is provided through either a 4G modem or Ethernet connection.
Complementing Existing High-Power Systems
Pedro Moreira da Silva, chief executive officer of i-charging, said the system was developed in response to increasing charging capabilities among newer electric vehicles.
“With the all-in-one 500, we are taking that further. While distributed solutions like our MAX, scaling up to 1600 kW across multiple power units, remain the reference for high-output multi-plug sites, the all-in-one 500 answers a different challenge: maximum power in a minimal footprint, for sites where space simply doesn’t allow a distributed installation.”
The launch follows the introduction of i-charging’s MAX charging platform earlier this year. Unlike the AiO 500, the MAX system uses a distributed architecture with a central power unit capable of delivering up to 1.6 MW of charging capacity across multiple charging points.
The new charger reflects the industry’s ongoing focus on higher-power charging solutions as automakers introduce electric vehicles capable of accepting increasingly faster charging rates.
