Facilitating plug-in vehicle uptake
Key documents and links:
The Smart EV project is funded by Scottish and Southern Energy Networks through its Network Innovation Allowance, and delivered by EA Technology. All six GB Distribution Network Operators are project partners. It is a follow on project to My Electric Avenue. The evidence from My Electric Avenue suggests that plug-in vehicles (PIVs) will cause an impact on the local electricity network, requiring significant investment by Distribution Network Operators (DNOs) an estimated investment of £2.2bn by 2050 will be needed to support PIV uptake. My Electric Avenue also demonstrated that demand side response solutions can work, and can work sympathetically with the network, PIVs and people for 3.5kW charging vehicles. It is likely that the roll out of this mechanism will facilitate increased numbers of PIVs that can charge without large scale network reinforcement, in the most cost efficient and expedient fashion. The roll out needs consideration; specifically, that compatible charging points are required in advance of the predicted increase in PIV numbers, this will require careful messaging with customers.
At present there is no standardised method of curtailing PIV chargers, and a number of manufacturers have developed proprietary systems. Left alone, this will lead to a multitude of system types with little commonality which would make adoption of PIV charge control much more difficult in the future.
The aim of this project is to achieve consensus on the mechanism that can be used to facilitate the roll out of controlled PIV charging. In doing so, it will enable significantly larger numbers of PIV charging on todays local electricity distribution networks, with sizeable reduction in investment costs and customer bills/disruption. This project will seek to inform2 a national engineering recommendation (or equivalent) for the connection, charging and control of new PIV load to domestic properties.
A key part of this project is to present the engineering options to a set of stakeholders, and seek opinions as to the most viable for all concerned. The first stage of this engagement was delivered through the Smart EV Consultation on Managed EV Charging that closed in December 2016. The results of the Consultation are available under Key documents and links’ on this page. The project is now moving towards a single viable solution which is backed by stakeholders. We will be consulting on the technical solution, i.e. a draft Engineering Recommendation for managed EV charging, in Summer 2017. We need the input of as many relevant stakeholders as possible charging point manufacturers, installers, EV manufacturers, policy makers, and others involved in the supply chain. If this project is relevant to your work, we would like to engage with you; we’ll make the process as straight forward and efficient as possible.
