Work Package Three

Smart Charging Technical Requirements

This work package will focus on the technical requirements for smart charging, aiming to provide a perspective on the following:

  • Cyber security, grid stability and data privacy
  • Communication requirements for smart charging including responding to common signals


Working Definitions:

  • Smart charging refers to shifting demand and procuring flexibility (including V2G) in response to a signal such as price.
  • Interoperability refers to the ability of devices to respond to common signals (it is not about interoperable chargepoint cables, payment methods, etc).

Specific questions

Work Package 3 should consider the following specific questions:

  1. What are the technical requirements for cyber security, grid stability and data privacy?
    i. Can internet connections be secure enough for smart charging? What are the viable alternatives?
    ii. Randomised time delays for responses from smart chargepoints might be needed for grid stability. How can this be done whilst mitigating the impact this would have on the ability of the chargepoints to be involved in frequency response services?
    iii. What level of testing (e.g. for cyber security) should chargepoints have?
    iv. What requirements are needed for these in relation to the disposal or re-selling of chargepoints?
  2. What are the technical requirements for interoperability?
    i. OCPP is very widely used as a comms protocol. Is this the starting point for interoperability or does it have barriers that can’t be overcome?
    ii. Beyond a common communications protocol or appropriate interface between protocols, is anything else required to achieve interoperability?
  3. 3. What are the technical barriers to getting the full benefits from smart chargepoints, including how they work together with smart meters (and smart cars)?
    i. What are the potential technical opportunities or limitations of using the smart meter infrastructure as the communications system for smart chargers?
  4. Are EU and international standards developing quickly enough to be useful at this stage? Will there be exceptions where the UK should deviate from them (e.g. for cyber security reasons or in order to be more closely integrated with UK smart meters)?
  5. What are the remaining technical barriers to innovation such as V2G and how can they be overcome?
  6. Can a single or small number of technical frameworks or architectures for smart charging be agreed at this point in time? If so, is this helpful/necessary or does it limit innovation?
  7. What are the product safety issues relating to smart charging?
