Stricter UK Regulations for Smart Charging in Electric Vehicles (EV)

The initial phase of the UK government’s Electric Vehicles (Smart Charge Points) Regulations 2021 was activated on June 30, 2022. The second phase, prioritizing heightened security measures, took effect on December 30, 2022. These regulations aim to address the escalating demand for electricity amid the country’s shift towards electric vehicles (EVs) and enhance security protocols.

Key requirements for new charge points under these regulations include pre-configured charging schedules, random delays of up to 10 minutes, increased smart functionality, tamper detection mechanisms, and secure software updates.

Noteworthy is that existing domestic and workplace chargers remain unaffected, and the regulations exclusively apply to England, Wales, and Scotland.

Understanding the Smart Charging Regulations

As the popularity of electric cars surges in the UK, the government has outlined specific regulations to legally define the capabilities of home and workplace chargers. A pivotal aspect of these regulations is the emphasis on smart charging functionality, allowing charge points to prioritize charging during periods of lower grid demand or increased availability of renewable energy.

These regulations also empower end-users with more comprehensive information and statistics regarding their charging events, coupled with enhanced security measures.

Motivation Behind the Regulations

The widespread adoption of EVs aligns with the government’s strategy to achieve net-zero greenhouse emissions by 2050. To support this transition, financial grants for homeowners and businesses, along with alterations to Building Regulations, have been implemented. While the rise in electric cars poses a potential challenge to the national energy grid, it is affirmed that the grid can meet this demand only if EV charging is optimized in terms of timing.

By establishing a more adaptable energy system, the grid is positioned to accommodate the UK’s EV transition. Furthermore, the changes promote the use of smart charging, facilitating the integration of clean, renewable electricity into the grid.

In essence, these regulations aim to elevate standards in the EV charging industry, fostering an intelligently managed and future-proofed energy ecosystem.

Key Features of the Regulations

Applicable from June 30, 2022:

  1. Default Charge Schedule: New charge points are required to come with a pre-configured default charging schedule, prioritizing off-peak hours to optimize electricity costs and alleviate demand during peak periods.
  2. Randomized Delay: Charge points must introduce a random delay of up to 10 minutes at the start or end of a charging session, spreading out demand to protect the grid from surges. Users can override the random delay by disabling the charge schedule temporarily or manually plugging in their EV without a set schedule.
  3. Increased Transparency on Charging Stats: Drivers must have access to detailed information on their charging sessions, including the total time of power flow and a comprehensive record of charging events over the last 12 months.

Applicable from December 30, 2022:

  1. Tamper Detection Mechanism: EV charge points must include a tamper detection mechanism, recording attempts to remove the front cover and notifying the owner.
  2. Security Event Log: Charge point owners must have access to a log of notifications related to their charger through a recorded security event log.
  3. Transparent Firmware Details: Users can now view their charge point’s software version and anticipate software updates as part of enhanced transparency measures.
  4. Updated Software and Security Standards: New encryption and authentication standards enhance the security of charge points connected to online networks.

Additional Requirements

Apart from the aforementioned features, the regulations encompass:

  • Smart Functionality: Charge points must enable drivers to charge their EVs during periods of lower demand or when clean energy is abundant, facilitating secure information exchange across a network.
  • Demand Side Response Services: Charge points must be capable of deferring or varying their charging rate in response to external signals, enabling energy firms to offer additional services based on electricity pricing and renewable energy supply.
  • Electricity Supplier Interoperability: Charge points should retain smart functionality even if the user switches to a different electricity supplier.
  • Loss of Communications: Chargers must continue to charge the vehicle even if they lose communication with the user’s network.
  • Safety Features: Users should be prevented from carrying out operations that endanger their safety or that of others.
  • Statement of Compliance: All charge points sold must include a Statement of Compliance document, showcasing adherence to the regulations, along with manufacturer details.

Looking Ahead – Future Guidelines on the Servicing of EV Chargers

The upcoming guidelines on EV charger servicing are expected to be released in the near future. These guidelines are being developed by the Department for Business, Energy and Industrial Strategy (BEIS) and the Office for Product Safety and Standards (OPSS). The guidelines will cover the following areas:

  • Safety requirements for EV chargers
  • Installation and maintenance requirements
  • Testing and certification requirements
  • Training requirements for EV charger technicians
  • Consumer protection measures

It is important to note that these are just proposals and the final guidelines may be different. However, they provide a useful indication of the direction of travel for EV charger servicing in the UK.

In the meantime, there are a number of things you can do to ensure that your EV charger is serviced properly, including:

  • Choosing a qualified EV charger installer
  • Following the manufacturer’s instructions for servicing your EV charger
  • Keeping your EV charger clean and free of debris
  • Reporting any damage to your EV charger to the manufacturer or installer

By following these guidelines, you can help to ensure that your EV charger is safe and reliable.
