At embedded world 2026 on the DigiKey booth, Paige Hookway spoke with Vanja Samuelsson, CEO of Qoitech, to explore how the company is reshaping low‑power design and battery testing for modern developers.
Qoitech is a Swedish company focused on providing solutions for developers around low‑power measurement, battery testing, and battery life estimation. As Samuelsson puts it, Koitek’s portfolio is centred on enabling developers to understand and optimise how their products consume power over time, without requiring them to become power or battery specialists.
There has been a major industry shift: engineers today are more often product integrators than narrow domain experts. Instead of designing every component from scratch, they are assembling systems from off‑the‑shelf hardware and differentiating primarily through software. This changes the demands on test and measurement tools, especially for power and battery analysis.
Samuelsson agrees, noting that the responsibility for power performance has expanded up the stack: “Now the software layers put on top of the hardware are as much making impact on the battery life as anything else, which means they need to take that responsibility.”
As a result, test and measurement instruments must support a system-level view of power, accessible to any type of engineer, not just the “hardcore specialist.”
This is exactly where Qoitech’s Otii product suite comes in. Rather than presenting a complex, lab‑centric tool, Qoitech has gathered all the necessary capabilities for low‑power optimisation and long battery life into a solution that is intentionally simple on the surface yet highly capable underneath.
A key part of this approach is the Battery Toolbox, a software license that enables developers to test and validate batteries for their specific product use cases. What makes it unique is its flexibility and the way it hides complexity: “Battery, anything with battery, is considered to be very complex… What we’re trying to do is take that complexity and put it behind so you don’t have to really think about it, but you’re served only the good bits and pieces that you can utilise in your product development.”
Developers can pick and choose and customise their workflow around low power, whether they are hardware engineers, embedded software developers, or teams automating measurements.
Qoitech is also showcasing a new battery life estimation feature at the show. Traditionally, teams either invest in expensive lab testing or rely on oversimplified spreadsheet estimates – for example, dividing battery capacity by average current. Samuelsson points out the flaw in that approach: there is no such thing as a “typical” usage pattern. Real products see a wide range of behaviours and use cases.
Qoitech’s new feature allows users to profile batteries for their specific usage scenarios, matching actual device behaviour and real‑world use cases with the right battery choice. The result is a much more realistic battery life estimate that developers can confidently present to customers.
Availability has also taken a major step forward. DigiKey has added Qoitech’s software toolbox to its offering, significantly expanding accessibility. Samuelsson highlights DigiKey’s strength in making tools easy to find and acquire, aligning perfectly with Qoitech’s vision of a “smorgasbord” of options that teams can tailor to their own workflows.
Looking ahead, Qoitech plans to continually evolve its portfolio, maintaining a “red thread” of usability, coherence, and speed. In a world where “nobody has the time to become the expert,” its mission is clear: deliver the expertise to developers, rather than expecting them to build it from scratch, and make complex battery and low‑power analysis feel light, approachable, and fast.
