Hubject is working with CharIN to integrate the organisation’s latest Public Key Infrastructure (PKI) for vehicle-to-grid applications into Hubject’s Plug&Charge system. The partners expect to complete the implementation before the year’s end.
PKI is one of the most common forms of internet encryption and has spread to other industries. Essentially, a public key infrastructure uses digital certificates and public-keys for authentication. In the case at hand, the technology enables the charging station and car to recognise each other and start running related processes. This is known as Plug&Charge, and, for example, allows automated communication and billing processes between electric vehicles and chargers.
In addition, CharIN’s latest V2G PKI supports vehicle-to-grid capabilities for grid balancing between vehicle batteries, stations and utilities. The PKIs, or electronic “keys” in the form of digital certificates, replace charging cards or apps and enable information flow based on ISO 15118.
Moreover, the CharIN procedure allows electric car drivers to charge via Plug&Charge with as many partners as possible with one contract in future. The so-called CharIN V2G Public Key Infrastructure (PKI) focuses on DC charging.
“At Hubject, we believe in a market-driven approach that allows every company to work with multiple service providers without any lock-in effect,” said Christian Hahn, CEO of Hubject.
The company adds it was a “landmark partnership” for the advancement of Plug&Charge capabilities. Both partners stress that the integration would provide greater convenience, security and accessibility when charging electric vehicles.
“After designing the V2G PKI by the CharIN members as a neutral and open V2G PKI, we are excited to see our V2G PKI integrated into Hubject’s ecosystem, bringing us closer to a broader deployment and availability of an even more customer-friendly e-mobility future,” said Michael Keller, board member atCharIN.
The Charging Interface Initiative (CharIN) has over 320 members. They seek to implement open charging standards and systems, like the Combined Charging System (CCS) and the Megawatt Charging System (MCS), based on the ISO/IEC Communication protocol.
Founded in 2012, Hubject is a joint venture of the BMW Group, Bosch, EnBW, Enel X Way, E.ON, Mercedes-Benz, Siemens and the Volkswagen Group. Its eRoaming platform intercharge connects Charge Point Operators (CPOs) and eMobility Service Providers (EMPs) to provide standardised access to charging infrastructure.
