Encryption key management tested in Amsterdam is vital for the next generation of EV charging systems says charger designer Tritium

Tritium has launched a secure cardless EV charging system that it says is the first of its kind.

The technology, based around the ISO15118 encryption 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 ‘plug and charge’ capability is available immediately for charge point operators to deploy on Tritium's PK350kW DC High Power Chargers and has been tested in Amsterdam and Germany.

Although the company is based in Australia, the technology was tested at Tritium’s innovation centre is in Amsterdam. "We placed our innovation centre strategically in Amsterdam and at the epicentre of Europe's automotive manufacturing sector," said James Kennedy, Chief Technology Officer and co-founder of Tritium. "That investment has paid off, and directly led to the rapid development of the technology. It's a major reason why we're first to the market with a secure and advanced charger technology once again."

The encryption technology allows drivers to use a charger regardless of the charging network operator with the charging session automatically and securely billed.

"This firmly and irreversibly tips the convenience scales to the recharging experience over the refuelling experience," said Kennedy. "It's going to be as simple as how we charge our phones, but with the added benefit of charging our bank accounts at the same time.

"There is no more need for a membership card or even to swipe a bank card at a terminal; this is the first and most secure iteration available to the market and, once deployed to critical mass, will render any former payment process as archaic."
