Frequently asked questions

brAIn by FUERGY consists of our proprietary components and components from external suppliers. FUERGY’s proprietary components include a hardware Control unit and AI-powered software. We have external suppliers for batteries, inverters, BMS or other materials. Most of them are Slovak or European suppliers. The only components that are currently supplied from Asia (China, Japan, South Korea) are the batteries and BMS.

At the moment, we use LiFePO4 batteries as they have optimal technical specifications for our solutions and 15 years lifespan guaranteed by the manufacturer. Unlike Li-Ion batteries, LiFePO4 batteries are non-flammable therefore they can be placed also in the interior of the buildings. brAIn by FUERGY solution is yet compatible with any kind of battery or energy storage. We can therefore manage the already installed energy storage systems even though the results might not be as good as if we use the LiFePO4 batteries. This also allows us to easily switch to new technologies on the market such as hydrogen storage or more efficient batteries based on sodium, sulfur or titanium.

Currently we mainly use batteries with the following technical specifications:

Battery technology: Li-ion (LiFePo4)
Efficiency (1C - rate): 95%
Depth of discharge (DoD): 80% (10 ÷ 90%)
Operating life: 15+ years
Number of charge cycles: > 5000

brAIn by FUERGY provides energy optimization for all electricity consumers, from households and SMEs to large manufacturing and warehousing companies, shopping centers, office buildings, residential complexes, data centers, petrol stations and many more.

The main goal of brAIn is to reduce the costs at the level of energy supply which translates into lower energy costs for all the involved parties, including the end customer. However, brAIn’s IoT functionality (Internet of Things) can, in some cases, lower also the energy consumption by smart control of the connected electric devices. For example, brAIn turns off the electrical heating when the situation in the power grid makes it financially convenient and the comfort of the end customer remains unaffected.

Yes. brAIn by FUERGY solution can bring greater financial returns to any kind of energy source. Even those sources which have already been installed.

The brAIn storage helps to partially eliminate micro-power outages, even in normal operation mode. However, in order to provide full UPS functionality, a part of the battery capacity must be reserved, constantly charged and ready to provide backup power whenever needed. This significantly reduces its ability to provide economically attractive flexibility and therefore extends the brAIn’s payback period. Provision of smaller back-up loads (on the order of units of kilowatts) does not significantly affect the return on brAIn storage.

Most conventional installations do not require a building permit, as it is a matter for reasonably large areas.

The financial effect is generated on the supplier or balance group side. Optimised management of the brAIn battery storage system by FUERGY helps to regulate energy consumption behind the smart meter, complying with the energy consumption plan of the delivery point. Through the delivery point and its electricity supplier, regulation electricity is provided instead of ancillary service providers. The electricity supplier saves its own resources and rewards the delivery point, i.e. the energy flexibility provider, on the basis of the savings achieved, according to agreement.

Our brAIn battery storage can provide spot arbitrage, peak shaving, solar surplus storage, reserve capacity guarding and curtailment and a variety of other services. Due to the low economic performance of such services, brAIn storage prioritises the provision of counter-deviation, i.e. flexibility for the electricity supplier in the form of non-certified ancillary services.

The price of brAIn by FUERGY solution is determined after the energy audit of a particular delivery point. brAIn is a highly scalable solution and its final configuration depends on the end customer’s special requirements, the annual energy consumption of the delivery point, connected technologies and many other variables.

Due to high demand, brAIn by FUERGY is currently only available for B2B customers such as SMEs, large factories, logistic parks, power plants, shopping centres or office buildings with annual energy consumption usually higher than 1 GWh. Ideally, the customer also operates the energy-intensive technologies with the potential for accumulation and regulation such as HVAC systems, air compressors, furnaces or water pumps. The eligible customer must either be a client of one of our partnered energy suppliers or his contract for energy supply from any other energy supplier is about to terminate. Find the list of the partners in EaaS FAQs under "Who are FUERGY’s partnered energy suppliers?". Please contact us at info@fuergy.com for further information. The sale of the solution brAIn by FUERGY to household customers is in the pipeline for Q3 2022.

Pylontech's batteries have a 15 year lifespan with an option for a 10 year warranty on the battery cells. Thanks to efficient FUERGY management, annual battery degradation is around 2.5 %.

We use LiFePO4 batteries from Pylontech, which in the case of a serious failure, will only smolder, not burn. This is why they can be installed in building interiors. Under normal operation, no gases are produced that need to be extracted.

The environmental impact of brAIn storage does not need to be assessed, with the exception of large solutions, i.e. an area greater than 25 m2.

Batteries in our brAIn solutions haven't reached the end of life yet. In the future, the ecological recycling of our batteries will be managed by the company SEWA a.s.. Nevertheless, our goal is to use all the technologies to the fullest. Even the batteries that have lost a significant part of their usable capacity can still be upcycled, serve as a backup energy source or provide an uninterruptible power supply. Renewable energy and batteries are constantly improving and there is still a huge unlocked potential. We also believe that soon we will have technologies much easier to recycle, with lower impact on the environment.

The brAIn battery storage is prepared for V2G, but the limitations are on the side of the electric vehicles themselves at the moment and the current legislation.
