TOPChargE System, Bornholm

A large test battery with an integrated HPC (High Power Charger/fast charger) is heading to Bornholm this week in connection with the EUDP-funded project “TOPChargE” and the EU-funded project “InsulaE”.

A 5-ton package from Danish Nerve Smart Systems has now landed on Bornholm. The package is a container filled with a large three-string battery able to fast charge electric vehicles with up to 350kW.


The battery is produced by Nerve Smart Systems, who received funding to develop charging functionalities directly from a large battery through the TOPChargE project.


”The synergy between the two projects is great. While we demonstrate high power charging in the TOPChargE project, the InsulaE project can benefit from all the other test results you get with a large energy storage.” says Jesper Boie Rasmussen, inventor of the battery technology ‘Nerve Switch®’ and CEO of Nerve Smart Systems .


Bornholm is once again able to test new green solutions. The charging infrastructure is crucial for the green transition of the automobile industry. I hope that the battery can bring attention and have more people test drive electric vehicles. And to then see themselves help make the island greener the next time the car needs to be replaced” says Caroline Meyer White, chair of the special committee on climate and sustainability.


The mobile battery, which will operate as a charger for electric vehicles, will be on Bornholm for a total of 2 years. During those 2 years the battery will move between two sites, the parking lot at Campus Bornholm and by Green Solution House, with 6 months intervals. The two locations will allow as many electric vehicle owners as possible to charge their cars from the battery. Two charging outlets will allow two electric vehicles to charge at the same time.


Cheaper and more energy efficient: Renewable energy flows directly into the battery

The large EU-funded project InsulaE’s purpose is to implement locally produced, sustainable and cheap energy sources into the energy systems of 3 European islands. The idea is that the battery system installed on Bornholm can serve as an inspiration for other islands in the EU who wants to lower their CO2 emissions.


The battery is connected to solar cells while stationed at Campus Bornholm, as part of the new innovative green solution. Normally power from solar cells is converted from direct current to alternating current and then back again to direct current before it’s then stored in a battery. But in this new battery, the power is steered directly into the battery. You can save both energy and money by not converting the energy, since the conversion causes energy losses and the conversion unit itself costs money. It will be a cheaper and greener way to get electricity, if the experiment with the new technology succeeds.


Additionally, the battery is an attempt to meet the challenges within the electricity grid which may arise over time when more electrical vehicles need to quickly charge at the same time. The charging stations existing today are connected to the electricity/power grid and the electricity is powered directly from the grid to the car. It is also difficult to ensure that the power, charging the cars, comes from renewables.


”The technology developed in the TOPChargE project, currently being tested within the InsulaE project, allows renewable energy to be stored in large batteries, which is then able to charge electric vehicles with minimal power loss. This concurrently also reduces the load on the electricity grid.” says Mattia Marinelli, associate professor from DTU coordinator for the InsulaE project.


From the 1st of July you can charge your electric vehicle with green/renewable power directly from the battery

The charging stations are being tested at the moment and will be fully functional for charging electric vehicles from the battery from the 1st of July 2021. The charger is a so-called high power charger (350 kW).


The project partners encourage all electric vehicle owners to swing by the battery and try the charger in order to test the technology in the batteries for the projects as thoroughly as possible. This will generate the best data set for the continued work to complete/finalize the technology.

Nerve Smart Systems battery technology will facilitate water production!

Atmospheric water generators from EAWD will be powered by energy stored in large battery systems from the Danish company Nerve Smart Systems. The batteries are powered by solar panels from the Swiss-German company Envelon. The systems will be installed in areas where it is not possible to dig wells or places with acute water shortage – for example in refugee camps in third world countries, densely populated cities or in deserts.

Water scarcity is a reality in every continent. Water consumption globally grew more than double the population growth in the last century. The world population has tripled in the 20th century, but the use of renewable water resources increased sixfold. Within the nest fifty years the world population will increase further by 40-50%.

Population growth, combined with industrialization and urbanization, will result in an increasing demand for water and the environment will face serious consequences if the practices are not addressed in time. An increasing number of regions, especially dry and arid areas, are close to reaching the limit of their sustainable drinking water supply.

To solve this problem, EAWD has designed their atmospheric water generator which Nerve Smart Systems will supply with an energy and battery system. The first system will be built in Hamburg, Germany. The delivery will then begin for other pre-ordered systems by countries including South Africa, Mexico, and others.

An Atmospheric water generator is able to extract drinking water with condensation from the moisture in the air. The atmospheric water generator originates from the mines, where this technology was used to cool the air resulting in the by-product, condensation. The system is powered by renewable energy stored in a large battery.

The overlap between when the system operates and when the green energy from the solar panels is available, does not always align perfectly. The battery system will make it possible to store the green energy, enabling a prolonged timeframe where the water generator can perform.

The battery also helps to reduce the need for a connection to the electricity grid. This opens up for the possibility that the system can be used in more places with primitive, or no, electricity infrastructure.

At the SDG Tech Awards on the 22nd of October, hosted by Sustainary, CEO of Nerve Smart Systems, Jesper Boie Rasmussen, received the award for Best Start-up. Nerve Smart Systems is very happy to be acknowledged in such a strong category together with other finalists; WorthmoreLulu LabEAT GRIM and WAIR.

Technology of all kinds must and can play an integral part in saving the world and integrating smart technology into society is Nerve Smart Systems’ main focus. Nerve Smart Systems won the award for Denmark’s best startup at the largest Nordic sustainability show, the SDG Tech Awards, for promoting sustainability as well as the UN’s sustainable development goals. The award was presented by Sustainary, a global platform for sustainability, in collaboration with Vækstfonden and Den Grønne Investeringsfond.

The jury, consisting of international and high-profile participants, chose Nerve Smart Systems as the winner. The jury was impressed by the way in which Nerve Smart Systems’ battery energy storage technology, Nerve Switch®, can help facilitate the integration of green energy in a CO2 neutral future.

Nerve Smart Systems wishes to bring a big thank you and a round of applause to our visionary investor, Ross Jackson, and the exceptional crew at Nerve Smart Systems who made this possible with all their hard work. We look forward to see how Nerve Switch® battery systems can influence and help speed up the electrification of society in the future.

Nerve Smart Systems would like to bring a special thank you to Sustainary, the partners; VækstfondenInno-MT – Innovationsnetværk for Miljøteknologi and Innovation Fund Denmark as well as the jury for this honor.

The SDG Tech Awards were a part of the Green Impact Week, an initiative with 5 days full of talks, workshops, exhibitions, and other activities with a sustainable focus. The main partners behind the Green Impact Week were Sustainary, Creative Business Network, DISIE, Frej and MakeImpact. The jury consisted of over 50 participants from the Department for International Trade (DIT)Atea DanmarkVækstfondenDISIE and Danfoss as well as many others.

Nerve Smart Systems is partnering with DTU (Technical University of Denmark), OK a.m.b.a. and Fremsyn on a new development project, which will integrate battery technology able to charge an electric vehicle with up to 350kW, while at the same time stabilize the power grid with minimal energy loss and high power electronics expense.

Among the three biggest challenges to the power grid of the future is the integration of renewable energy, the charging of electric vehicles and consumption curves that do not match the production. One of the primary reasons why people decide to not buy electric vehicles is the current charging infrastructure and the long waiting time it takes to charge the electric vehicles when driving more than 300 km.

The potential for an integrated battery solution which can both store renewable energy, stabilize the power grid and fast charge electric vehicles is therefore huge. “We will be able to deliver a battery buffered High Power Charger (B-HPC) that is at least 30% cheaper than the competing solutions while also cutting the energy loss in half compared to the traditional power electronics” says Jesper Boie Rasmussen, CEO of Nerve Smart Systems ApS.

TOPChargE, as the development project is called, is led by a strong and diverse consortium that includes Nerve Smart Systems, Technical University of Denmark, Fremsyn and OK A.M.B.A. One of OK’s 670 fuel stations is expected to be used as a demonstration of the B-HPC on both a technological and commercial level.

Nerve Smart Systems’ technology, Nerve Switch®, is unique because the voltage level can be controlled directly at the cell level. By either activating or bypassing individual cells in a large battery string, it is possible to adjust the amount of voltage, depending on the need, both when charging and discharging the battery. A prototype of the Nerve Switch® battery was developed with financing from EUHorizon2020 and a private investor. The additional support to the TOPChargE project from both the EUDP and IFD will be used to, respectively, develop and demonstrate the integration of power grids and charging of various electric vehicles in practice.

Currently there are no other systems that are able to integrate a battery storage in a fast charger, without using expensive power electronics to control the amount of kW the system can use to charge an electric vehicle with. When the cheaper charging integration is combined with the opportunity to offer various services, that battery storages integrated into the power grid is able to do, then you have a really great foundation for both the society and companies.

We are, for example, able to charge the battery storage when the power grid is receiving an overproduction of wind energy, to later use this energy to charge electric vehicles or send it back to the power grid when renewable production is lower. We can facilitate a greater use of green energy for both charging electric vehicles and powering ordinary households”, says Jesper Boie Rasmussen, CEO of Nerve Smart Systems.

The partners and their contribution:

Nerve Smart Systems ApS: is the work package leader of high-power charging, system integration and design of battery systems as well as developing, designing, and commissioning of high-power charging system.

DTU: will test the control of conventional fast chargers for electric vehicles in combination with a battery as well as test the charger prototype (B-HPC) being developed in the project. DTU will also test and research the integration between the B-HPC and the power grid.

OK a.m.b.a.: With more than 670 fuel stations, OK provides access to Denmark’s most extensive infrastructure within resource distribution for the transport sector. The OK corporation already buys and sells power; therefore, it is a natural next step for them to become charge point operators. They will then sell power in a similar fashion to how they sell fuel today. OK will develop the IT system that will handle the payment system and the communication with other Emobility service providers.

Fremsyn ApS: will prepare financial analyses which will help underpin various services related to the stabilization of power grids and business opportunities for the consortium partners.
