Battery Management Systems

Joe O’Connor, Director of ESS Solutions at Nuvation Energy, examines ways ESS developers are reducing their project and business-risk through modular approaches to ESS design that anticipate supply chain challenges and innovation opportunities.

Nuvation Energy CEO Michael Worry explores the current state of the art in battery cell balancing, and how BMS innovations will impact the future of stationary energy storage.

Honeywell today announced its collaboration with Nuvation Energy to integrate an improved battery management system (BMS) into Honeywell’s modular battery energy storage system, Honeywell Ionic™.

Nuvation Energy’s new fifth generation battery management system can provide up to a 25% cost per kilowatt-hour ($/kWh) reduction over their fourth generation BMS when used in 1500 Volt stationary energy storage systems. This new BMS also supports the most recent updates to UL1973 (UL 1973:2022).

Many Nuvation employees drive electric vehicles, including to our office, where they plug into an EV charging post. While this started racking up Nuvation’s utility bill, the team decided to build our very own Battery Energy Storage System.

When we couldn’t find a suitable battery management system for our electric vehicle project, we decided to make one ourselves. With our electronic design experience, we were confident we could build exactly what we needed.

In the event of a grid power failure, this compact 588 kWh ESS outputs 2 MW of power for 15 minutes. It transitions a wastewater treatment plant in Santa Rosa, CA from grid power to diesel backup generators.

Nuvation Energy provided battery management solutions for Islas Secas, a 100% solar powered resort off the coast of Panama. We developed a custom energy storage solution controller, as well as a battery management system to expand their battery storage capacity.

Electric Applications chose Nuvation Energy’s battery management system to manage their 960 VDC 1 MW / 1 MWh grid-attached energy storage system. This lead-acid energy storage system was installed by City Utilities in Missouri.

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 shares our experience in energy storage system design from the vantage point of the battery management system. In part 1, we present module and stack design approaches that can reduce system costs while meeting power and energy requirements.

Nuvation Energy shares our experience in energy storage system design from the vantage point of the battery management system. In part 2, we share experience working with UL to create UL 1973 Recognized stack level solutions.

Nuvation Energy shares our experience in energy storage system design from the vantage point of the battery management system. In part 3, we explore pain points that energy storage system developers and operators can encounter in the field.

Principal Software Architect John Chinnick presents a behind-the-meter distributed energy resource (DER) infrastructure that includes solar generation, energy storage, and a utility grid connection serving a commercial or industrial load.

Nuvation Energy CEO Michael Worry takes a closer look at how energy storage system providers and users can track battery utilization to verify adherence to warranty parameters, and also to proactively identify and resolve problems before they result in battery damage.

Take a quick dive into how our battery management system’s operator interface works. Nuvation Energy CEO Michael worry demonstrates all aspects of our OI, including measurements, voltages, cell balancing, and more!

In our final webinar in this series, “Battery State of Health in Energy Storage Systems” Stefan Janhunen, Principal Software Architect and battery measurement algorithms developer at Nuvation Energy, takes a deeper dive into battery State of Health.

BMS Designer Alex Ramji walks us through Nuvation Energy’s battery management products for high-voltage applications. These solutions are designed for use in large scale applications such as utility-grid support in front of the meter and demand charge management behind the meter.

Battery Management System designer Alex Ramji provides a walk-through of Nuvation Energy’s Stack Switchgear (SSG), a stack-level battery management system that is generally located above or below each stack in a large-scale high-voltage (i.e. 60-1250 V DC) energy storage system.

Nuvation Energy CEO Michael Worry alongside Business Development Engineer Joe O’Connor talk about a variety of performance and long term ownership requirements to take into account when choosing the right energy storage system.

Nuvation Energy CEO Michael Worry discusses what makes Nuvation’s battery management systems different from any other product on the market. He also introduces the nController energy management system and why its functionalities are so important.

When an automotive battery comes out of its first life usage, it can still have 70% or more of its useful capacity remaining. The batteries must be stored, recycled or redeployed in second life energy storage. Nuvation Energy has successfully field deployed many second-life energy storage systems.

Did you know that as an avid energy storage enthusiast in his personal time, Nuvation Energy CEO Michael Worry is involved in the development of battery powered robotic beer kegs, and fire breathing mutant vehicles?!
