EV charging It will be crucial for all enforcement suppliers What plug and to sign up to the ECBs charge does is accreditation process turn your EV into as creditors will want to a secure digital engage rms that operate wallet, meaning to its standards seamless payments without the need to install dedicated stand-alone payment terminals To meet the scale of the EV transition, all car park spaces will require a charger that has adopted the ISO 15118 standard. Plug, charge and walk away is the end goal for any parking provider by the end of the decade, he says. It makes it a seamless, frictionless, onestep process for the public to pay for parking and get their car charged, while removing the need for even more street furniture and expense for the taxpayer. In addition, it moves parking providers towards being a part of the solution, and not just a drain on the network. These connections will mean energy can be taken from EV batteries back into the grid at periods of high demand where possible, and protect the grid from increasing demands. Revving up for a green light For Jonathan Allan, BPA head of technology, innovation and research, the technology is just waiting for the green light from manufacturers. With more OEMs incorporating the technology into their vehicles, and the security questions being addressed, this technology is very close to becoming mainstream and car park operators need to be ready for the changes. With VW joining BMW and Tesla, we are seeing this technology becoming far more widespread across the motoring public. The vehicles that currently support the plug and charge ISO 15118 standard include the 2021 Porsche Taycan, Mercedes-Benz EQS, Lucid Air, Ford Mustang Mach-E, and all vehicles manufactured by Tesla from 2012. Currently, several vehicle models from the VW Group are equipped for plug and charge. With its decision to adopt ISO 15118, this smart charging function is expected to be used as a standardised method from 2025. For Gow, the technology provides a win-win for car park operators. In essence, what plug and charge does is turn your EV into a secure digital wallet, meaning seamless payments without the need to install dedicated standalone payment terminals. The plug and charge technology is sophisticated enough that it could offer a billing account for personal and corporate use, so this should also help simplify the public charging process for personal mileage and business mileage alike. It has the potential to deliver a great customer experience as well as being an efficient operation. Join the BPAs EV Connect group for more on all things EV. See britishparking. co.uk/EV-Connect-Group Watch the first meeting of the group, that took place in October, at britishparking. co.uk/Interest-Group-Meeting-Records (member login required) How a plug and charge session works The payment process begins with the initiation of authentication for the EV at the charging station. Plug and charge facilitates an automated exchange of asymmetrically encrypted certificates between the EV and the charging station. Digital certificates are encrypted using a private key during transmission and decrypted at the receiving end using the corresponding public key. This encryption mechanism ensures the authenticity and integrity of the payment information. The entire payment transaction relies on the secure infrastructure provided by vehicleto-grid (V2G) root public key infrastructures (PKIs), ensuring a trustworthy environment for financial transactions. Operators of V2G root PKIs adhere to ISO 27001:2013 standards, undergoing regular information security audits to validate the quality and security of their payment processes. Through these audits, operators demonstrate the adherence to international standards, assuring stakeholders in the e-mobility sector of the reliability and security of the plug and charge payment process. 14 16 PN Dec 2023 pp12-15 Lead Feature.indd 14 30/11/2023 11:33 m215
