Hubject intercharge eRoaming and Plug&Charge

Hubject is a Berlin-based eMobility company that has worked since 2012 on connecting charge point operators (CPOs), eMobility service providers (EMPs) and vehicle manufacturers so drivers can charge across networks and borders. Its shareholders shown on the site include BMW Group, Enel, E.ON, Siemens and Volkswagen, and it has offices in Berlin, Shanghai and Los Angeles.

Its intercharge platform is a business-to-business eRoaming hub: operators connect once and gain access to partners' charging stations and customers, with process monitoring, analytics and EVSE data quality scoring. Plug&Charge lets compatible vehicles authenticate and pay automatically when plugged in, using certificate-based identity. Hubject also offers testing and certification, settlement and clearing through Hubject Financial Services, and advisory services. The network reports more than 1.1 million connected charge points, 3,500 B2B partners and operations in over 75 countries.

• intercharge eRoaming: one connection gives CPOs and EMPs access to partner networks across 75+ countries.
• Plug&Charge: certificate-based automatic authentication and payment when the vehicle is plugged in.
• Analytics and monitoring: process monitoring, analytics and an EVSE data quality score.
• Financial services: settlement and clearing of charging transactions between partners.
• Testing and certification: interoperability testing for chargers, vehicles and back ends.
• Advisory: consulting on eMobility ecosystems, including truck charging reservation systems.

Vietnamese charging operators can open their stations to drivers of other networks and earn roaming revenue through one hub. Automakers selling EVs in Vietnam can offer Plug&Charge so owners charge without separate apps. Charging app providers can aggregate stations from multiple operators for fleet and ride-hailing drivers.

Operators reach a large pool of drivers and partner stations through a single integration instead of many bilateral roaming contracts. Plug&Charge removes cards and apps at the charger, improving the driver experience for automakers and networks. Central settlement and clearing simplifies billing between partners, and testing services help hardware and vehicles work together before launch.

As public charging networks multiply, drivers face fragmented apps and cards, pushing operators and automakers toward roaming and automatic authentication standards such as ISO 15118 Plug&Charge. In Southeast Asia, several new national networks are emerging in parallel, creating demand for interoperability between operators, automakers and cross-border travel.

Active since 2012 and based at the EUREF campus in Berlin with about 140 employees. Shareholders shown on its site include BMW Group, Enel, E.ON, Siemens and Volkswagen. Operates Hubject Ltd in Shanghai and an office in Los Angeles, and joined Mexico's Electro Mobility Association in 2026.
