Why the Right BMS Partner is Essential for Energy Storage Success

The energy storage industry is continuously expanding, which means selecting the right Battery Management System (BMS) has become more critical than ever. As the foundation of safety and protection for your Energy Storage System (ESS), a BMS not only optimizes performance, security, and longevity, but also plays a critical role in overall system reliability. With many options on the market and given the critical role a BMS plays in your system’s success, choosing the right BMS partner requires careful consideration. In this article, we outline the key factors to consider when selecting a battery management system partner.

Quality Design and Manufacturing

Where and how a battery management system has been designed, assembled, and manufactured has a direct effect on the safety, security, and efficiency of the energy storage system it is used in. BMS providers who do not utilize trusted components, manufacturers, and distributers, can lead to faulty systems which can result in frequent maintenance, unplanned downtime, security threats, and higher operating costs.

The entirety of Nuvation Energy’s product design process is driven by a strong commitment to reliability and quality. With over a decade of experience in research and development for battery management systems, Nuvation has refined its BMS technology to be robust, adaptable, and compliant with critical safety standards.

By partnering with trusted manufacturing sites and implementing both internal and third-party inspections, this guarantees every component within Nuvation’s BMS is sourced from a trusted manufacturer and distributer, eliminating risks of counterfeit or grey market components.

With our North American based contract manufacturing facilities we have full oversight and control through our proprietary production test infrastructure, ensuring every BMS meets the high standards required for complex and large-scale energy storage systems. Every unit Nuvation Energy produces undergoes a series of comprehensive tests to validate quality, functionality, and reliability of the BMS. This includes detailed PCB testing to verify circuit quality, high-voltage testing to meet UL standards, and functional testing through Burn-In, ensuring the BMS is built to perform reliably from the start and engineered to eliminate the possibility of early or unexpected failure. Nuvation also retains detailed logs of all test results for every unit produced, which are stored in a secure system for easy retrieval, review, and analysis of historical data to continuously advance performance and quality over time.

Commitment to Safety Standards and Compliance

The role of a reliable BMS goes beyond operational efficiency. It is also a critical safety component for your energy storage system. Nuvation Energy’s BMS was recognized as the world’s first configurable third-party BMS to achieve UL 1973 Recognition, highlighting our dedication to safety and reliability.

To gain approval in most jurisdictions in North America, Battery Energy Storage Systems (BESS) must meet the requirements of UL 9540, the standard for safety in energy storage systems. Within a UL 9540 certified BESS, individual battery stacks must comply with the UL 1973 standard, ensuring safety for stationary and most auxiliary power applications. A BMS that meets these certifications simplifies the overall process for system certifications and significantly reduces the certification effort.

Nuvation Energy’s BMS products meet UL 1973 standards for stationary energy storage, UL 60730-1 standards for functional safety, and an array of other standards, reducing the effort and costs involved in achieving the required certifications for your energy storage system.

Dedication to Secure Solutions

Cybersecurity is a critical concern for energy storage systems. A single unauthorized access incident could allow for nefarious actors to infiltrate an ESS remotely, potentially compromising control systems, disabling safety mechanisms, and even leading to catastrophic failures such as system fires. This serious hacking threat makes it essential to prioritize cybersecurity when selecting and implementing battery management systems. Designed to prioritize safety and security, Nuvation’s BMS meets UL 1973 standards, which mandate the ability to lockdown critical safety configurations, protecting the system against malicious attacks that could cause unsafe operation, damage to the equipment, and result in catastrophic failures. To further enhance security, Nuvation guarantees the authenticity of both the hardware and software and uses encrypted and digitally signed firmware updates, ensuring that only authentic updates are accepted by the BMS hardware. These measures provide advanced protection against unauthorized access and compromised products.

Nuvation Energy’s approach to cybersecurity reflects over a decade of experience designing and deploying battery management systems in highly secure facilities, including government medical research facilities, water treatment plants, and power plant emergency backups. These critical applications demand the upmost attention to security and reliability, and our solutions are trusted to meet these crucial standards.
