(LUND, SWEDEN; November 16, 2020) – The Swedish cleantech company Comsys AB announced today that it has successfully demonstrated the repurposing of used EV batteries for industrial peak shaving applications.
Recent trials of an onsite energy storage installation built by Comsys using swapped-out EV batteries has enabled a sawmill in Germany to increase production by 100% by making it possible to run a second saw without limitation. The objective of the project was to study this second-life battery application as an alternative to installing additional capacity from the grid, which is typically too costly, to supply the peaks of a highly variable load.
The test project is a response to the growing opportunity for the power sector resulting from rising global growth of electric vehicles – stationary storage powered by used EV batteries. This is a relatively new opportunity that, according to an article published by McKinsey & Company in April of 2019, “could exceed 200 gigawatt-hours by 2030.” Dan Liljengren, Head of Research and Innovation at Comsys, explains why the sawmill made a good choice for the trials.
“In applications like sawmills, the power is very volatile due to the significant difference between high load and low load, and the demand fluctuates as a natural part of the sawing process. For such applications, often situated in remote areas, a battery installation can supply the saws at high load demand to supplement the limited power available from the grid. At low load the battery is charged.”
The result of the pilot trials showed that the sawmill was able to utilize the power connection to the maximum and overcome a previous limitation of only using one of two big saws simultaneously, thus doubling production capacity. Liljengren says that Comsys’ solution, which is modular and fully scalable to fit the needs of various industries, offers several significant advantages.
“Not only does it allow the owner to sidestep large investments in grid infrastructure, but it also provides quick response, contributes to a circular economy and can save industries money by not having to pay for electricity at peak demand.”

Since its start 18 years ago, Comsys has been a pioneer within the field of power quality, leading the way among the global active filter market, having established many features that today are now considered standard. As Comsys’ journey continues, they have strengthened their portfolio by acquiring Netpower and MagChoke, further adding more expertise to their offering and gearing up to tackle the energy challenges of tomorrow.
To unify these brands and solidify their offering as one company, “ADF Power Tuning” will now simply be “ADF”, together with the brands “Netpower” and “MagChoke”. They have chosen to focus on their original brand and company name, Comsys, profiling it as a leader not only within power quality but now also within grid applications.
Our extended portfolio makes the circle complete as we now also can offer energy storage, grid connection and DC solutions which enables us to be part of the tomorrows challenges with renewable energy, microgrid, charging etc. – Rickard Jacobson, Head of Sales and Marketing
Along with the expanded portfolio is a new brand visual identity that will carry Comsys into the future. Their customers from the utilities, marine, oil & gas, data center, water treatment, renewables and other industries will get the same great solutions and service as they always have but might notice a new look.
Comsys, together with our global network of partners, provides grid and energy solutions to industry leaders worldwide, enabling them to increase productivity, and simultaneously save money while reducing their carbon footprint. We achieve this through a competitive offering of AC and DC products, including their patented technologies ADF, Netpower and MagChoke.

Swedish research and technology easily end up outside the country's borders. Through the acquisition of MagComp AB's unique and patented inductor technology Magchoke, Comsys AB ensures that the technology is protected and developed further.
When MagComp, a Swedish company with roots in Lund University, decided to sell the part of the company that focuses on inductors, Comsys made sure to win the negotiations.
- With the acquisition of MagComp's inductor operations, we ensure that Swedish research, technology and expertise stay in the country. We also secure a key component in our existing products, at the same time we gain access to resources to further develop the technology, says Marcus Löfgren, CEO of Comsys.
The patented technology MagChoke® is about replacing the conventional magnetic core with inductors with metal powders that are mixed in epoxy and then moulded around the coils, giving unique properties at the same time as the manufacturing cost is lower.
The power electronics company Comsys, with the product ADF Power Tuning, has a solution that delivers the right power quality to industrial customers all over the world. An important ingredient in the ADF is precisely inductors, which act as "shock absorbers" for quick changes in the electric current.
Today's society is becoming increasingly dependent on electronic equipment, while the quality of the electricity network is falling and the vulnerability is increasing, component damage, disruptions and long power outages are becoming increasingly common.
- The increasing use of electricity also creates a risk for energy shortages and an infrastructure that is not related to the rapid development. When, for example, a car or bus is to be charged in a very short time, parts of the electricity grid do not cope with the load, but there the ADF helps the technology and relieves the process.
The need for energy storage and micro networks increases and the inductor technology in MagChoke® will continue to be important building blocks in our products in these areas, continues Marcus Löfgren.
Manufacturing and personnel are transferred to Tramo ETV in Eslöv, a well-reputed company that for more than 30 years has built up a solid experience through the manufacture of just inductive components.
