EV Charging Infrastructure
Date of Completion: May 2025
About this Project
Project Overview
BDS Global was commissioned to deliver a full-scope electrical and civil design for the installation of electric vehicle charging points (EVCPs) at a residential site known as “The Close.” The project aimed to support the growing demand for sustainable transport by integrating a reliable, safe, and regulation-compliant EV charging solution.
Design Methodology
BDS Global adopted a structured and standards-driven approach to the design and delivery of the EV charging infrastructure. The project began with a comprehensive site assessment and feasibility study, followed by the development of detailed electrical and civil engineering plans. The design process was underpinned by BS 7671:2018 + A3:2024 and incorporated MODECSOFT ElectricalOM software for precise load, fault, and voltage drop calculations
Electrical Design Summary
The electrical system was anchored by a three-phase 100A DNO supply, feeding into an Open PEN-protected distribution board. The board supported four EV sockets across two posts, each protected by RCBOs rated at 40A/10kA/30mA. The design ensured:
- Balanced load distribution across phases (L1, L2, L3)
- Voltage drop well within the 5% limit
- Earth fault loop impedance and disconnection times compliant with BS 7671
- Surge protection and isolation devices for enhanced safety
Outcome
The project was delivered on time and in full compliance with all technical and regulatory requirements. BDS Global’s integrated approach—combining electrical engineering, civil design, and regulatory navigation—ensured a seamless deployment of EV infrastructure that is scalable and future-ready.
