The terms “full” and “empty” are therefore inaccurate in this context of “never completely full” and “never completely empty.” That’s why battery industry professionals instead prefer to use the term State of Charge (SoC) to refer to the degree to which a battery has approached the lowest or highest recommended level of charge; 100% SoC is not \u2018full’ but is “as full as the system designers said we should go” and 0% SoC is not \u2018empty’ but is “as empty as the system designers said we should go.” These thresholds are programmed into the battery management system where they are accessed by the PCS and used to prevent overcharging and over-discharging. ... In Nuvation Energy’s battery management system, Depth of Discharge refers to how many amp-hours (Ah) of the total battery capacity have been used ... Nuvation Energy’s battery management system adds a technique called coulomb counting to its approach to calculating SoC when a battery is in use ... Nuvation Energy’s battery management system has solved this problem with proprietary algorithms that also include additional sensor data. ... In an application with a small number of lead-acid cells, replacing a lead-acid battery from time to time may cost less than integrating a battery management system into the ESS ... Nuvation’s battery management system provides users with the ability to log into the BMS user interface and change the maximum DoD threshold settings within minutes in order to derive more capacity from the battery. ... As with most electronic equipment, all battery management systems are not created equal, and some perform their role better than others ... Nuvation Energy battery management systems are designed from the ground up for use in large-scale high-power applications and critical energy infrastructure ... We are confident that when you evaluate our battery management systems, you will be very impressed.

Nuvation Energy’s battery management system provides two levels of response when a battery is moving out of its nominal operating parameters ... As cell temperature, current, and voltage drift outside of (i.e: above or below) nominal parameters, the battery management system will generate a \u2018Warning’ to the human user and/or to automated control systems in the battery pack, alerting them that although the battery is still operating within safe parameters, it is getting too close to the edges of those thresholds ... Nuvation Energy’s battery management system also enables the implementation of user-defined thresholds that can trigger responses from the PCS and other devices in the energy storage system ... This screenshot from Nuvation Energy’s battery management system is generating a Warning that the stack voltage has dropped below 720 Volts, the minimum required by the PCS used in this energy storage system being used at a municipal wastewater treatment plant. ... Figure 1 is a screen capture of Nuvation Energy’s battery management system managing a Nuvation-designed 2MW / 588 kWh energy storage system ... If you are in the market for a battery management system for your ESS, it would be prudent to ask if it utilizes open or proprietary communications protocols, and to understand the level of effort that will be required for system integration ... Nuvation’s battery management system uses the open MESA protocol to enable the sharing of sensor data received by the BMS ... Control systems that manage energy storage applications such as PV smoothing, frequency regulation, and demand charge management are dependent on data from the battery management system regarding the level of charge available in the battery packs, as well as the amount of energy available in the ESS ... Nuvation Energy’s battery management system performs cell balancing by diverting energy from the cells that are charging faster than others.

Nuvation Energy battery management systems include a feature called Open Wire Detection which detects damaged, loose, disconnected, or incorrectly torqued sense wires ... Nuvation Energy battery management system modules \u200bundergoing electromagnetic interference susceptibility testing at TUV facilities. ... An incorrectly torqued sense wire can deliver incorrect readings to the battery management system. ... Nuvation Energy’s battery management system can provide power to the contactor coils directly, which strengthens its reliability as a safety system by enabling it to de-energize the contactors without assistance from any additional components. ... Nuvation Energy’s battery management system allows the alignment of the contactor to be programmed into the BMS ... The role of a battery management system is to ensure that the battery never exceeds its nominal temperature, voltage and current limits.
