Tritium charger

Tritium technology charges your EV and bills you automatically

Electric vehicle drivers now have the potential to charge their car at public chargers without any hassle involving RFID tags or bank cards. An EV can be plugged in and the technology can charge the car and bill the driver’s bank account automatically.

Tritium, a world leader in electric vehicle DC fast charging technology, has launched its game-changing Plug and Charge solution, the first of its kind in the world available to the market.

The technology, leveraging the ISO15118 standard, enables an electric vehicle and charger to communicate seamlessly and authorise payments directly from the driver’s account, without the need for a card or RFID tag. The Tritium offering is the first to market and is available immediately for charge point operators to deploy on Tritium’s PK350kW DC High Power Chargers.

The technology promises to reshape the customer experience for the driver and enable the once-siloed approach to charging payments to be broken down with disparate charging networks able to interoperate. Drivers will be able to approach a charger, regardless of the charging network operator, and their charge session will be automatically and securely billed from the moment the charger plug connects to the vehicle.

A third party, such as Hubject – which provides an automated and secure data exchange enabled by ISO 15118-conforming Public Key Infrastructure – is responsible for cryptographic certifications between the vehicle and the charger, and the technology ensures Tritium is securely storing cryptographic keys on the charger side in a way that other chargers can’t.

Right now, it’s likely that EV drivers approaching an EV charger will have to sign up for that network’s system to access it and pay for the charging session, adding unnecessary time to the experience and siloing charger networks.

Buy-in and adoption on a large scale from charge point operators is required for the technology to hit the critical mass required. 

Electric vehicles will also need a way to secure the vehicle-side cryptographic key which will become common place with emerging models.

The Tritium Plug and Charge technology has been tested in a live setting at a number of its PK350kW DC High Power Chargers in Germany.

The Tritium Plug and Charge solution has also been repeatedly tested at the Tritium E-Mobility Innovation Centre in Amsterdam, where automotive manufacturers have been able to test vehicles for interoperability with Tritium’s suite of DC chargers and software technologies, including Plug and Charge.

As new vehicles begin to be rolled out and with them the technology to secure the cryptographic key on the vehicle side built into the vehicle itself, the technology will lead to a new era for electric vehicle drivers.

Tritium solely focuses on DC fast charging (DCFC) and high-power charging (HPC). Tritium has deployed over 4,500 charging stations and provided over 600,000+ charging sessions in more than 33 countries. Tritium currently holds around 50 per cent of the world-leading market in Norway and between 15 to 20 per cent of the wider western global market for DC fast chargers. Tritium is currently the majority supplier to the IONITY network and the largest supplier of 350kW DC HPCs in Europe.
