For electric vehicle (EV) owners navigating the UK's motorways, reliable and accessible charging infrastructure is paramount. Birchanger Green, a prominent service area, has been a focal point for EV charging discussions. This article delves into the current supercharger situation at Birchanger Green, providing clarity for drivers planning their journeys.

Birchanger Green Supercharger Facilities
Birchanger Green, located at the Welcome Break service area on the M11 Motorway (N/S) at Junction 8, offers charging facilities for electric vehicles. Historically, information regarding the exact number and type of chargers has sometimes been varied. However, recent observations and developments shed light on the current and future capabilities of this location.
Current Supercharger Availability
As of recent reports, Birchanger Green has boasted 4 Superchargers available 24/7. These chargers are compatible with the CCS standard and offer charging speeds of up to 150kW. This provides a solid foundation for EV drivers needing to top up their batteries while on the move. The 24/7 availability is a crucial aspect, ensuring that drivers can charge at any time, irrespective of service area opening hours.
Upcoming V3 Supercharger Expansion
A significant development at Birchanger Green is the addition of 20 new V3 Superchargers. These are being installed in the main services carpark. While the build is reportedly finished, the chargers are currently fenced off and awaiting commissioning. This indicates a substantial upgrade to the charging capacity at this location. V3 Superchargers are known for their enhanced performance, including faster charging speeds and the ability to share power dynamically between vehicles, optimising the charging experience.
What are V3 Superchargers?
Tesla's V3 Superchargers represent a significant advancement in charging technology. Key benefits include:
- Faster Charging Speeds: V3 can deliver up to 250kW, although the actual speed depends on the vehicle's charging capability and battery temperature.
- Dynamic Power Sharing: Unlike older versions, V3 chargers can distribute power more efficiently. When multiple cars are plugged into a V3 station, the power is shared dynamically, meaning the car with the lower state of charge receives more power.
- Reduced Wait Times: The combination of higher peak speeds and dynamic sharing generally leads to shorter charging sessions and less time spent waiting.
- Preconditioning: For Tesla vehicles, V3 supports battery preconditioning, which warms the battery to the optimal temperature for faster charging as the vehicle approaches the Supercharger.
Compatibility and Access
The existing Superchargers at Birchanger Green are CCS compatible. The new V3 Superchargers are also expected to support CCS, broadening accessibility for a wider range of electric vehicles, not just Teslas. Information regarding access and payment for the new chargers may be communicated via notices, potentially involving ANPR (Automatic Number Plate Recognition) cameras. Drivers are advised to check with the hotel or any posted information for specific instructions upon arrival.

Planning Your Charge
When planning a stop at Birchanger Green, it's essential to be aware of the current status. While the 4 existing chargers are operational, the new V3 chargers, though built, are not yet active for public use. This means that during peak times, the existing chargers could experience demand. Having a backup plan or checking real-time charger availability through EV charging apps is always a good practice.
The development at Birchanger Green highlights the ongoing investment in EV charging infrastructure across the UK. As more V3 chargers come online, this location is set to become a more robust and efficient charging hub for electric vehicle drivers. The addition of 20 V3 units will significantly increase the capacity and reduce potential wait times, making longer journeys more convenient.
