Specialist Electrical Design for EV Charging Infrastructure
EV Design provides independent electrical design consultancy for commercial, fleet, public sector and high-power EV charging infrastructure across the UK
A specialist EV infrastructure design brand by JBSE Consulting Engineers
Electrical Design Support for EV Charging Projects
EV Design is the specialist EV infrastructure design brand operated by JBSE Consulting Engineers Ltd, providing focused electrical engineering support for commercial EV charging, fleet electrification, public charging, high-power DC hubs, eHGV charging and emerging megawatt charging infrastructure. It is a design consultancy rather than an installer or a charge point operator, and works with clients across the UK. If you are considering appointing an EV charging consultant, that page sets out what an engagement covers and when to bring one in.
Our work focuses on the electrical systems that make EV charging projects technically robust, buildable and commercially viable. This includes site capacity assessment, DNO and iDNO application support, LV distribution design, cable sizing, protection coordination, IEC 60287 cable thermal analysis and electrical tender documentation.
Projects are supported from feasibility through to construction, whether that means establishing what a site can take before equipment is chosen or producing the drawings and specifications a contractor needs to price and build the scheme.
Trusted project experience across the UK EV charging sector.
Jonathan has produced construction-ready electrical designs for commercial, fleet and public sector EV charging infrastructure projects across the UK, working alongside leading charge point operators, principal contractors, infrastructure providers and public sector organisations.
Specialist electrical engineering for EV infrastructure
Commercial EV charging, eHGV charging, emerging megawatt charging infrastructure and the detailed electrical engineering that underpins each project.
Engineering expertise at every stage of your EV infrastructure project.
Successful EV charging projects rely on far more than charger selection. Electrical capacity, distribution design, protection, earthing, cable routing and long-term infrastructure planning all influence whether a project can be delivered safely, efficiently and without unnecessary cost. EV Design provides the specialist electrical engineering needed to develop coordinated, construction-ready designs from feasibility through to completion.
In practice that means settling the questions that shape a scheme early: how much capacity the existing supply can release, what the DNO or iDNO will require, how the cables can be routed and rated for sustained charging load, and how earthing and protection need to be arranged for the charging equipment proposed.
Technically Robust Design
Designs are developed in accordance with BS 7671, the IET Code of Practice for Electric Vehicle Charging Equipment Installation, IEC standards, DNO requirements and charging equipment manufacturer guidance, providing a coordinated and technically robust design solution.

IEC 60287 cable thermal analysis for high power EV charging
Standard BS 7671 current carrying capacity tables are based on defined installation conditions. High power EV charging often involves grouped buried ducts, high continuous currents and varying ground conditions, so installation specific thermal assessment can be critical.
Installation-specific thermal modelling
We assess cable thermal performance using IEC 60287, considering installation conditions such as burial depth, soil thermal resistivity, duct configuration, cable grouping and operating temperatures.
Applied where the installation requires it
IEC 60287 analysis is used where standard cable rating methods do not adequately reflect the proposed installation, particularly for grouped buried ducts, high current circuits and thermally constrained routes.
Reduces thermal design risk
Assessing the governing installation condition helps identify thermal constraints early, supporting compliant cable selection and reducing the risk of overheating, premature cable degradation or costly redesign.
What an EV charging infrastructure design covers
A complete EV charging design draws on several disciplines at once. Feasibility and site layout work establishes how many bays a site can support and where they sit; capacity assessment and DNO coordination establish what the supply can deliver; and cable sizing, IEC 60287 thermal analysis, earthing, protection and RCD coordination establish how the installation is built and protected. The capabilities below are the parts of that work EV Design carries out.
The kinds of EV charging projects we design
EV charging schemes tend to fall into a few recognisable shapes, and each places a different demand on the electrical infrastructure: available site capacity, the distribution and cable routes needed to reach the bays, and the headroom left for chargers added later. The three examples below cover commercial, fleet and public sector charging.
Commercial Charging Hub
Multi-bay rapid charging for retail and destination sites.
HGV Fleet Charging
High-power depot charging for electric HGV fleets.
Workplace Charging Scheme
AC charging for workplace and employee car parks.
