Our battery energy storage systems are sustainable, modular and maintenance-friendly by design, with unique hardware features that enable smooth installation and seamless operation.
Battery Management System
Our sustainable energy storage solution comes in both an indoor and an outdoor battery cabinet to suit your specific needs. The Octave cabinets are designed for a smooth installation, and are made of durable and strong materials.
Our indoor battery cabinet uses energy-efficient air cooling, engineered to keep the second-life batteries in optimal shape.
Our outdoor battery cabinet is durable and weather-resistant. The insulated cabinet is integrated with air-conditioning and heating units to keep the batteries in an optimal temperature range while installed outdoors.
Both the indoor and the outdoor battery cabinets can be equipped with a fire detection and extinguishing unit.
Our Octave battery cabinet houses used batteries from electric vehicles. When these batteries come out of the electric vehicle, they typically retain an energy storage capacity of 80% or more.
For stationary energy storage the lower requirements for charging power, better controlled temperatures and weight and space being less of priority, means that these batteries can easily last another 10 years.
We have designed a flexible and modular racking system to host these battery modules from electric vehicles. The racking system is able to host multiple types of batteries, and allows for quick replacement of specific battery modules, maximizing the lifetime of the system.
Our in-house designed battery management system keeps the batteries in safe operation at all times. We re-use part of the electric vehicle’s battery management system, designed to meet the highest quality automotive standards.
Our battery management system is developed to support batteries from different types of electric vehicles.
The battery management system connects to our Battery Cloud for fully remote monitoring and management. More than one million data points are logged per battery system per day.
The battery management system is housed in our battery protection unit, which is equipped with an array of electrical protection equipment. The protection unit is fully redundant, making sure the system operates safely and reliably.
Weather data is continuously captured by the Battery Cloud to finetune the forecast of the renewable energy production and to adjust the battery control accordingly.
The plethora of data coming in the Battery Cloud are used to optimally control the battery system to maximize revenues, as well as to carefully study the degradation of each individual battery cell to maximize the lifetime of the battery.
Digital twins of the batteries are created in the Battery Cloud, to evaluate the health and remaining capacity of each battery cell.
The Octave battery cabinet is the center piece of the site's energy management. Its smart control enables to optimize the energy flows and decrease the electricity bill.
Grid frequency data and other data coming from third-party aggregators are integrated in the Battery Cloud, unlocking lucrative grid services opportunities with the Octave battery cabinets.
Power market prices (day-ahead, intraday or imbalance) are integrated in the Battery Cloud, unlocking arbitrage opportunities with the Octave battery cabinets.
We distinguish ourselves from traditional battery suppliers by leveraging data from the battery system and building up an extensive history of measurements from each battery cell.
Our Battery Cloud monitors every measurement from each individual battery cell in our battery systems, in real-time. More than one million data points are logged per battery system per day.
This detailed and remote monitoring allows us to deliver a system with excellent performance and increased safety. Anomalies are detected prematurely and optimization is performed continuously.
The battery data is made accessible in our Client Zone, where you can observe and explore the performance of your battery system remotely.
Our battery cloud gathers and stores all the data streamed by our battery systems in the field. This data is used to run advanced analytics and to examine the details of the battery system, down to a cell by cell level.
Using this data, we are able to create a digital twin of each battery cell, and feed our State-of-Health model to evaluate the cell's remaining capacity. Machine learning continuously improves our understanding of the behavior of our battery systems.
This unlocks data-driven predictive maintenance possibilities: Octave is able to perfectly forecast when to replace a used battery module and, by doing so, extend the lifetime of your system.
We offer an optional Optimal Control service with our battery systems. With this service, we optimize the charging of batteries in our Battery Cloud. We forecast energy prices, local solar and wind production and consumption peaks. This data is used to optimize the charging and discharging of the battery system.
Our cloud-based control algorithms also enable the participation in grid services and arbitrage on power markets.
