Electronic Design for Energy and Power Systems

Energy hardware doesn’t get a “patch Tuesday”. It sits on infrastructure for twenty years, outdoors and unattended, and when it fails someone gets in a van and drives to it – getting it right matters.

The electronics specialists you need in your corner

Many companies building energy products are not electronics companies. Your edge is your application, your process or your market, not power electronics and precision sensing. Energy programmes punish that gap harder than most: your product has to survive fault conditions, satisfy a network operator, meet a moving regulatory target and still be supportable in 2046. When a programme needs that depth, hiring it permanently is slow and expensive, and a single contractor is a risk your stakeholders can see.

We aren’t your typical run-of-the-mill consultancy with barriers between you and our engineers. We’re a specialist embedded electronics lab who work hands on with Product Leads, R&D Managers, Innovation Managers and Heads of Engineering in organisations who need additional expertise to get their device to market, quickly, professionally and with confidence.

We come in as that team for the part of the programme that needs us, lead the electronics with a structure your stakeholders can see, and reduce the technical and commercial risk of your product off you.

Sensing that survives real world fault conditions

Almost everything an energy product claims about itself starts as a current or voltage measurement, and those measurements have to stay honest at rated load, during a fault, and after twenty years of thermal cycling. We select and design the sensing against the actual requirement rather than habit, across current transformers, Rogowski coils, Hall-effect and shunt measurement, and we budget the error so the accuracy your metering or protection depends on holds at the temperature extremes and at end of life.

Power conversion and control

We design the power electronics at the core of the product: AC-DC, DC-DC and grid-tied conversion stages, protection and interlocks, isolation, and the embedded firmware and control loops that run them. This is high-current, high-voltage design where the failure modes are physical, and we design for them from the architecture rather than filtering them out at the end.

Battery energy storage and battery management

A storage product is a power electronics problem, a measurement problem, a safety problem and a communications problem in one enclosure. We design the battery management and cell monitoring, contactor and pre-charge control, isolation monitoring, current sensing and thermal monitoring, and the conversion stages either side of the pack, along with the state-of-charge and state-of-health estimation the rest of the system relies on. We scope the applicable storage safety standards into the programme at the start, when the architecture can still accommodate them.

EV charging

Charging hardware has to satisfy a vehicle, a network operator, a payment system, a regulator and a driver in the rain, and most of the difficulty is in the interfaces rather than the power stage. We design the charging electronics, the control and safety, the residual current protection and the communications, from the vehicle interface to the back-office protocols, and we will tell you which version to build to as a commercial decision, not just a technical one.

Grid connection, comms and cybersecurity

If your product exports to the network, its route to market runs through the network operator, and the connection requirements are a design input rather than a test you pass at the end. We design the protection and control behaviour to the required characteristics and build the evidence as we go. We also design the communications that let a distributed asset be monitored from somewhere else, across the utility and industrial protocols and the practical wireless routes, and the isolation, surge protection and EMC that keep the link up when a breaker operates a few metres away. Product cybersecurity, now law rather than good practice, is built in from the start: secure boot, signed updates, credential handling and the logging a reporting obligation actually needs.

Across the energy sector

Every energy product is built on the same electronics core: power conversion, sensing, protection, isolation, firmware and connectivity. That is our day-to-day work, and it applies whether the product is grid or distribution equipment, battery storage, EV charging, renewable generation, hydrogen or metering. What changes between them is the sector-specific regime sitting on top, from a grid-code connection standard to a metering approval, and we scope that into the programme from the start, exactly as we scope the compliance route for any product.

Recovering product development that has stalled

A proportion of our energy work is remedial. Power electronics failures tend to be systemic rather than component level, which is why they are hard to isolate and why teams arrive here late.

Some common situations:

The product fails EMC, or fails only when a nearby breaker operates
Sensing accuracy drifts with temperature or degrades under fault conditions
A network operator or type-test submission has come back with problems
Cybersecurity requirements have landed on a design that wasn’t architected for them
The battery system passes at cell level and fails at system level
A key power semiconductor, controller or sensor has gone end of life

We diagnose before we quote, which on a stalled power programme means instrumenting the thing properly and reproducing the fault. Which is unglamorous but it is the only way to avoid spending a re-spin on a guess.

Is this you?

You produce grid or distribution equipment, battery storage, EV charging hardware, metering, power quality or power conversion products
You sit in an innovation, product development or R&D function with an approved business case and a deadline
You need a partner your internal stakeholders can be confident with, not an individual contractor
You want the risk in your product development schedule managed, not the hours filled

We’re probably not right for you if you want to buy engineering hours to direct yourself, or if the concept has no commercial case behind it yet. If you’re earlier than that, we’d suggest reaching out to us for a Discovery Workshop or Feasibility Study first.
