Do you know the details behind our advanced battery pack?

Combined with our advanced bi-polar NiMH battery technology the Nilar EC Battery pack is a safer, greener, more reliable and cost-efficient energy storage solution.

By starting our production process already from the raw material, we control the entire cost structure and performance of the battery. Unlike our competitors, we own cell production to our batteries, thus avoiding surprises and optimizing their properties. By placing our flat cells in a lasagna structure in our building block, the module, which we then build together into battery packs that can be varied in different sizes, makes us distinguish ourselves from other battery companies. Our 12-module pack, which corresponds to as many as 250 cylindrical cells, is ideal for large electrical energy storages and systems.

Batteritillverkaren som går emot strömmen

Trots påtagliga tecken på klimatförändringar fortsätter många tillverkare inom batteribranschen att tillverka icke återvinningsbara produkter med kort livslängd. Med tekniska innovationer vill batteritillverkaren Nilar gå emot strömmen och vara en del av lösningen för en mer hållbar framtid. 

Marcus Wigren, VD på Nilar AB med ett Nilar EC Battery pack

I en värld där klimatförändringarna ständigt gör sig påminda med fallande grundvattennivåer, extrema väderförhållanden och smältande glaciärer är hållbara och långsiktiga lösningar ett måste. Användning av energilager och energi från förnyelsebara energikällor såsom sol och vind är en sådan lösning, som balanserar dagens mestadels fossila bränsleekonomier. Tillverkning av lagringslösningar är resurskrävande och därför är produktens livslängd viktig. Trots detta fortsätter många tillverkare att producera batterier med begränsad livslängd som efter ett antal år måste bytas ut mot nya. Många av dessa är dessutom inte 100 procent återvinningsbara och hamnar slutligen i stora deponier.

Nilar har valt att gå emot strömmen och erbjuder energilager med batterier som är återvinningsbara. Batterierna produceras dessutom på ett effektivt och miljövänligt sätt i bolagets egen tillverkningsanläggning i Gävle som drivs av 100 procent förnybar energi. Den senaste i raden av bolagets tekniska innovationer är en process som möjliggör att batteriernas redan långa livslängd kan förlängas markant. Genom ett samarbete med ledande forskare från Stockholms Universitet har bolagets forskningsteam utvecklat en process där syre förs in i batteriet när det är i bruk, och på så sätt förlängs produktens livslängd avsevärt. Genom innovationen kan användaren göra besparingar både ur ett miljömässigt och ekonomiskt perspektiv.

”Vår nya teknologi ger en revolutionerande möjlighet att fylla på med liv i ett redan befintligt batteri. Detta är ett stort steg framåt mot ett fossilfritt och hållbart samhälle.” säger Marcus Wigren, vd på Nilar.

Nilar EC Series with Nilar Hydride® batteries

Revolutionary Nilar Hydride® battery technology delivers unparalleled energy storage life

Swedish industrial battery manufacturer, Nilar, has developed a method for multiplying the life of its Nilar Hydride® batteries (NiMH). After years of research at its Swedish and US R&D centers, and in close collaboration with leading researchers from Stockholm University, the company made the game-changing announcement in December 2018.

The limited lifetime of batteries is an issue for users. Thanks to the new patented process, the Nilar Hydride®batteries will be able to handle considerably more charging cycles – and thus store and deliver far more energy throughout their lifetime – than other industrial battery technologies. This equates to a significantly reduced cost per kWh, which provides the lowest total cost of battery energy storage available on the global market. The robust, safe and environmentally-friendly characteristics of the battery are unaffected by this breakthrough.

“With this technology breakthrough we have found a way to re-condition a battery,” says Professor Dag Noréus from Stockholm University. “Typically, in Hydride batteries, the metal hydride in one of the electrodes slowly consumes the water-based electrolyte, which connects the plus and minus poles. However, the unique design of Nilar batteries makes it possible to counteract this aging process of the metal hydride. Adding oxygen causes new water-based electrolyte to form in the battery. This replaces the lost electrolyte and restores the internal electrode balance. With the right balance of oxygen and hydrogen, Nilar batteries can reach a lifetime that surpasses other corresponding battery technologies.”

Speaking about the breakthrough Nilar CEO, Marcus Wigren says, “A long service life is extremely important for our customers. Being able to offer the lowest cost energy storage solution to commercial real estate and private households gives us a huge competitive advantage. Research, development and innovation have always been an important part of our business and it is very satisfying to see our investments continue to give such good results. Protecting the environment is also one of our key drivers; being able to hugely extend the life of a battery is a big step towards a fossil-free and sustainable society.”

Michael Obermayer, Nilar’s Chairman of the Board, adds: “The European Union has set itself the goal of regaining leadership in the strategically important battery industry, and is committing significant supporting funds. With this fundamental innovation, we have laid the foundation for a new Swedish research-based battery industry. I believe Nilar is now a key player in this new European strategy and we will continue our fast move towards the company’s IPO.”

Nilar plans to launch the new patented technology for the Nilar Hydride® batteries later this year.

Nilar helps create sustainable accommodation in Holland

Through an efficient use of solar panels, a wood pellet boiler and batteries from Nilar, Dutch company Nieuw Leven has managed to create one of the most sustainable accommodation properties in Europe

When Nieuw Leven Accommodation decided to completely renovate their properties and relaunch under a new modern concept, a desire to minimize their environment footprint was at the heart of this. With a focus on sustainability, they needed a reliable energy storage solution that was in line with the new concept.

To promote self-sufficiency, Nieuw Leven invested in solar panels and a wood pellet boiler that can produce electricity. This included 97 Solarwatt 0,3kWP mono solar panels, producing an average of 29,1kWP. The panels provide power through a 27.6kW PV ABB TRIO inverter. Any excess energy is transferred to a 48 kWh Nilar rack system via a 50kW ABB ESI battery inverter. The entire process is managed by a Lovato energy management system, which ensures a smooth flow of electricity throughout the properties.

“A sustainable goal also includes sustainable batteries; The Nilar system is not only the safest battery in the market, they are also fully recyclable and contain no cadmium, mercury or lead. A logical choice for us!”, says Martijn Eelman, co-owner of Nieuw Leven.

Thanks to the combination of solar panels and an efficient energy storage system, Nieuw Leven can be reasonably self-sufficient during the sunniest times of the year. The energy produced during the day is both used to provide guests with electricity and stored in the Nilar system for use in the evening. During the winter months, when necessary, the wood pellet boiler provides energy for hot water and heating and can meet electrical requirements if necessary.
