AbOUT ZPN ENERGY
British Engineering Solving Grid Constraints for EV Charging and Energy Management
Solving the EV and Energy Problems Others Can't
ZPN Energy designs and manufactures battery backed DC fast chargers and integrated energy management systems that solve a critical problem: how to install rapid EV charging infrastructure when your grid connection can't provide enough power.
Whilst competitors assume you've already got sufficient grid capacity, we've built our entire business around the reality that most car dealerships, fleet depots, charge point operators, and commercial sites face severe grid constraints. Our patented ring topology technology allows you to install twice as many chargers on your existing grid connection without expensive upgrades that can cost £100,000+ and take 18 to 24 months.
The ZPN Difference: 99% Performance vs 68% Industry Standard
Our battery backed chargers deliver 99% of advertised charge rate, 99% of the time. Independent Monte Carlo simulations prove standard grid tied chargers only achieve this 68% of the time. For charge point operators, this means higher utilisation, better customer satisfaction, and significantly more revenue per site.
This isn't marketing hyperbole. It's patented technology that competitors can't replicate, proven at installations including Electric Seaway (marine charging with severe power constraints), major fleet operators, and commercial charging hubs across the UK.
What We Do
Battery Backed DC Fast Charging
We manufacture HUBZ, Core, and Lite rapid chargers with integrated battery energy storage that multiply your available grid capacity. Whether you need 50kW, 150kW, or 350kW charging power, our systems store energy during off peak times and release it when vehicles need rapid charging, eliminating the grid constraint bottleneck.
Integrated Energy Management Solutions
Beyond EV charging, we design complete energy solutions combining solar generation, battery storage, EV charging infrastructure, and intelligent grid management. One supplier, one integrated system, properly engineered to work together rather than cobbling together components from multiple vendors.
Mobile Rapid Charging (ZAPME)
Our ZAPME division provides mobile EV recovery and charging services, bringing rapid charging to stranded vehicles at the roadside or to locations where fixed infrastructure isn't available. Used by recovery services, car importers, and fleet operators across the UK.
Containerised Battery Solutions (Drop)
ZPN Drop is our containerised, relocatable battery energy storage solution designed for sites where you want the flexibility to move your investment if initial site selection doesn't deliver expected performance. Available from 120kW to multi megawatt configurations.
British Engineering, Non-Chinese Networking
ZPN Energy is one of the few EV charging manufacturers with predominantly UK based design and manufacturing. Our Coventry facility produces equipment to British engineering standards with non-Chinese networking, providing critical infrastructure security that government bodies, defence contractors, and security conscious organisations require.
For customers handling sensitive data or operating essential infrastructure, our non-Chinese networking eliminates cyber security vulnerabilities whilst our UK based engineering team provides support you can rely on.

Industry Firsts and Technical Leadership
ZPN is the first manufacturer worldwide to achieve:
OCPP 2.0.1 Compliance: Our chargers were designed from inception to be fully compliant with Open Charge Point Protocol 2.0.1, ensuring future proof integration with any backend management system.
PAS 1899:2022 Exceeding Standard: We're the only manufacturer exceeding PAS 1899:2022 (Electric vehicles – Accessible charging – Specification), with recoiling cables that make charging accessible for wheelchair users and those with limited mobility whilst eliminating trip hazards and ground contamination.
Patented Ring Topology: Our unique battery architecture allows simultaneous charging and discharging, eliminating the conversion losses and performance limitations that plague traditional battery backed systems.
Marine Environment Operation: Electric Seaway demonstrates our technology working in one of the harshest environments possible. If it works reliably in a marine environment with salt spray, temperature extremes, and limited shore power, it'll work anywhere.
The ZPN 5: Our Values
Energy: We're focused on solving real energy challenges, not building technology for technology's sake. Every product addresses a specific customer problem.
Management: Intelligent energy management systems that use IoT and machine learning to optimise performance, reduce costs, and maximise renewable energy utilisation.
Innovation: We don't copy competitors. We develop patented technology that solves problems they can't address.
Sustainability: Enabling the transition to electric transport and renewable energy by making it practical for sites with grid constraints.
Delivered: From initial consultation through design, manufacture, installation, and ongoing support, we execute on our commitments.
Who We Serve
Car Dealerships: Install rapid charging for handover and stock management without expensive grid upgrades.
Fleet Operators: Depot charging solutions that maximise limited grid connections whilst supporting rapid vehicle turnaround.
Charge Point Operators: Install profitable charging hubs on sites competitors can't access due to grid constraints.
Commercial Property: Retail parks, logistics warehouses, hotels, and hospitality venues adding EV charging without disrupting existing operations.
Marine and Specialist Applications: Ports, marinas, and other challenging environments where traditional solutions fail.
Proven Performance in Real Environments
Our technology isn't theoretical. It's delivering results right now:
Electric Seaway runs battery backed DC fast charging in a marine environment with severe grid constraints and salt spray exposure. The installation demonstrates both the reliability of our equipment and the effectiveness of small battery arrays (50 to 100kWh) for harvesting energy from constrained supplies.
Major Fleet Operators across the UK use our depot charging solutions to operate electric vehicles that would otherwise be impossible due to grid limitations.
Car Dealership Groups have eliminated handover charging bottlenecks, ensuring every customer collects their vehicle fully charged without expensive infrastructure investment.
Commercial Charging Hubs are generating revenue on sites that were previously unviable due to insufficient grid capacity.

Technical Excellence
We don't just assemble components. We engineer complete solutions:
In House Design: All core technology designed by our UK engineering team, not outsourced or white labelled.
Manufacturing Control: Coventry facility gives us complete quality control and rapid iteration when customer needs require customisation.
Testing and Validation: Every system undergoes comprehensive testing including Monte Carlo simulations, environmental stress testing, and real world validation before customer delivery.
Ongoing Development: Continuous improvement based on field performance data and customer feedback, not just annual product refreshes.

The Challenge We're Solving
The UK's grid infrastructure was designed decades before electric vehicles existed. Most commercial and industrial sites have grid connections sized for their building loads, not for rapid EV charging on top of that baseline demand.
Upgrading grid connections costs £50,000 to £250,000+ and takes 12 to 24 months. During that time, you can't charge vehicles, you're losing potential revenue, and competitors who've solved the problem are capturing your customers.
ZPN's battery backed charging technology solves this constraint problem, allowing you to install rapid EV infrastructure immediately without waiting for grid upgrades or spending six figures on electrical work.
That's the problem we've dedicated our business to solving. If you're facing grid constraints that are preventing EV infrastructure deployment, we can help.
