Upgrading the Electrical Supply at Chertsey Ambulance Station
Enhancing Infrastructure for EV Charging Efficiency
Chris Bartholomew Electrical Contractors Ltd was tasked with upgrading the electrical supply at Chertsey Ambulance Station to facilitate the installation of two new 22kW twin 3-phase EV chargers. As emergency response teams transition towards sustainable transport solutions, ensuring a reliable and high-capacity power supply is essential to support the growing demand for electric vehicles. Our work focused on enhancing the station’s electrical infrastructure to provide a stable, efficient, and future-proof charging solution.
Assessing the Existing Electrical Infrastructure
Before commencing installation, our team conducted a comprehensive assessment of the existing electrical supply. As an NICEIC-certified contractor, we evaluated the station’s current power distribution, load capacity, and overall electrical infrastructure to determine the feasibility of integrating the new high-powered EV chargers. Given the station’s 24/7 operational requirements, our upgrade needed to be executed efficiently and with minimal disruption to emergency response services.
Upgrading the Electrical Supply
To support the 22kW twin 3-phase EV chargers, we implemented a supply upgrade, ensuring the system could handle the increased power demand. Our work included:
Upgrading the main distribution board to accommodate the additional electrical load.
Installing dedicated circuit protection to safeguard against power surges and system overloads.
Enhancing cabling and wiring infrastructure to support high-powered EV charging capabilities.
Integrating load balancing technology to optimise energy distribution across the ambulance station’s electrical network.
These upgrades ensured that the new chargers operated at full efficiency, providing fast, reliable charging for the station’s electric ambulance fleet while maintaining a stable power supply for the facility’s other electrical needs.
Installing the EV Charging Units
Once the electrical infrastructure was upgraded, we proceeded with the installation of two 22kW twin 3-phase EV chargers. These chargers are designed to rapidly charge multiple emergency vehicles, ensuring they are always ready for deployment. The installation process included:
Positioning the charging units for easy access and efficient fleet management.
Wiring the chargers to the upgraded power supply, ensuring a seamless connection.
Implementing safety mechanisms such as RCD protection and surge suppression to prevent electrical faults.
Configuring smart charging features, allowing for scheduled charging and optimised energy consumption.
Our expertise in EV charging infrastructure ensured that the installation was completed on time and fully compliant with UK electrical safety regulations.
Ensuring Long-Term Performance and Sustainability
As part of our commitment to quality, we conducted comprehensive testing on the new electrical supply and EV charging units, ensuring optimal performance and safety compliance. The upgraded system now supports sustainable fleet operations, helping the ambulance station reduce emissions and operational costs.
The successful completion of this project highlights Chris Bartholomew Electrical Contractors Ltd’s expertise in providing specialist electrical upgrades for emergency service facilities.
