The Moura lithium-battery BESS is an energy conversion and storage system made up of storage technology, monitoring, control and a power system, an innovative energy solution for the Brazilian and global markets. It makes more efficient use of energy, storing surpluses and covering shortfalls depending on the type of application and the time of supply. In general terms, energy storage is a systems-integration technology that allows better management of energy supply and demand. The main components of the system are the lithium battery pack, energy management system, inverter, thermal management system, rack structure, electrical elements and fire detection and suppression system.

The EMS (energy management system) is a hardware and software system that automatically controls the operation of the storage system through connectivity and machine-to-machine communication. The EMS receives the inputs, assesses operating conditions, calculates the optimal operating profile and issues the outputs that make the best use of the stored energy, including the right times and limits for recharging; in other words, it monitors the performance of the BESS.

7,300 cycles, 97% depth of discharge.

Lithium battery bank used in small, medium and large energy storage systems (SAEB, internationally known as BESS). The battery bank is a set of lithium cells grouped into packs or modules, which are mounted in racks that can be installed outdoors or housed in a panel or container. The solution includes the BMS (Battery Management System), which monitors the batteries, and a cooling system, either liquid or air-conditioned.

Moura lithium stationary batteries, 48 V to 51 V, used in backup (MLF) and solar (MSL) applications, offer high performance, safety and durability through lithium iron phosphate (LiFePO4) chemistry. They have an integrated BMS (cell management system) that monitors battery functions and voltage, current, temperature protection and alarm parameters. The integrated BMS measures current, voltage, cell surface temperature and battery ambient temperature. Combined with computer management technology, the BMS enables real-time monitoring and control of multiple parameters and states. Designed for rack mounting, the battery is configured so that all operation (power cable connections, communication and indicator lights) takes place on its front panel.

The monitoring and control system (EMS) is used in small, medium and large energy storage systems (SAEB, internationally known as BESS). The EMS controls and monitors the BESS so that it operates correctly, and is the key element that allows the BESS to perform its function.

EMS hardware.

System dedicated to the management and control of battery energy storage systems (BESS). It coordinates BESS operation in different modes (on-grid, off-grid or hybrid) and handles power dispatch, charge and discharge control, safety limits, real-time monitoring and operating strategies such as peak shaving, arbitrage and backup. It works together with the PCS and the BMS, ensuring optimised performance, safety and compliance with the technical requirements of the application.

The EMS receives input signals, continuously assesses operating conditions, calculates the optimal operating profile and issues the commands needed to make the best use of the stored energy, choosing the ideal times to charge and discharge within technical and safety limits (performance monitoring).

The EMS allows operating profiles to be configured and controlled in real time. Data is also synchronised with a cloud storage service and accessible through a dedicated graphical interface.

The EMS is also responsible for safety monitoring, receiving signals from sensors across the system, such as temperature, smoke, fire, flooding and humidity. When conditions fall outside safety parameters, alarms are triggered automatically to notify operators and, in critical cases, the system can be shut down automatically to prevent greater risks (machine-to-machine communication, connectivity).

The Energy Management System (EMS) is the hardware and software solution that monitors, controls and optimises the operation of battery energy storage systems (SAEB, also known as BESS) and coordinates the interaction of the BESS with renewable sources and the grid, in on-grid and off-grid applications.
The REIVAX EMS can control and integrate BESS with solar plants, wind farms and the main grid, and can also interact with diesel and gas generators. This control relies on complex algorithms (machine learning) developed in-house by the REIVAX engineering team to optimise the use of energy sources and load consumption, as defined by the user.
Built with high-technology components, the REIVAX EMS operates with real-time monitoring, allowing secure remote access to the plant to monitor and assess faults and events in real time, in line with cybersecurity standards (ISO 27001), so that the user can act on accurate, concrete information. The EMS also takes decisions based on data from multiple devices on site, such as BMS, PCS, fire suppression and thermal management systems, among others, safely respecting the plant’s operating limits, and suggests predictive maintenance, extending component life.
The EMS manages multiple sources to meet strategic objectives such as peak load reduction, dispatch scheduling, renewable output smoothing, reduction of fossil fuel use, backup, self-restoration, islanding and microgrids, within the requirements set by the grid operator (Grid Procedures). It applies from front-of-the-meter (FTM) to behind-the-meter (BTM) projects: in FTM projects the EMS operates standalone and co-located (hybrid) plants, while in BTM projects it orchestrates multiple sources and devices to ensure supply reliability for critical loads and data centres.

Industrial automation and control panel, designed and assembled in Brazil, for the management, monitoring and control of power flow in small, medium and large battery energy storage systems (BESS / SAEB). The equipment acts as the physical central processing unit of the system, providing the critical communication and command interface between the battery bank (BMS), the power inverters and converters (PCS), the grid billing meters and the site loads.

The product is connected, collecting process data and storing it in the cloud, with remote access to operating and productivity data in real time (Industry 4.0 features).

The bidirectional power conversion system (PCS) is used in small, medium and large energy storage systems (SAEB, internationally known as BESS). The PCS charges and discharges the batteries, converting AC to DC and DC to AC. It includes communication protocols, built-in cooling, AC and DC side electrical protection, and is manufactured to Brazilian standards.

Fire detection and suppression system for BESS installations, made up of a wireless repeater panel, smoke and heat detectors, gas detectors, manual call points, audiovisual alarms, relay command modules and condensed aerosol suppression devices.

The solution supervises the protected areas and transmits events over a wireless network, allowing local signalling and activation of safety devices. The relay modules execute the commands and interlocks defined in the design, including automatic release of the extinguishing agent when the programmed conditions are met.

The configuration must take into account equipment layout, wireless coverage, protection zoning and a safe alarm and suppression sequence.

Integrated fire detection, alarm and automatic suppression system designed for stationary battery energy storage systems (BESS). It comprises a control panel, smoke and heat detectors, audiovisual signalling devices, electrical interfaces, cabling and aerosol extinguishing agent generators. The system monitors the protected space, identifies incipient fire conditions, raises alarms and automatically triggers discharge of the extinguishing agent. It is installed inside the BESS container or enclosure, with the number and capacity of devices sized to the protected volume and the characteristics of the storage system.

The fire suppression system is applied to battery energy storage systems (BESS) in compliance with Brazilian standard NBR 17240. It uses the latest generation of FPC compound, made up mainly of potassium salts free of pyrotechnic substances. Once activated, the FPC compound turns into a highly efficient, fast-expanding condensed aerosol that spreads evenly through the protected space using the momentum generated by the transformation. It extinguishes the fire not by depleting oxygen or by cooling, as the traditional fire triangle would suggest, but by interrupting the chemical chain reactions taking place in the flame.
