CellSage: Battery Health Analysis and Prognostics Software
CellSage is an advanced battery and electrochemical analysis tool from Ridgetop Group, that assesses battery condition based on the specific chemistry, usage conditions, and the environment in which it operates, with benefits that include safety improvements, faster reaction times, greater diagnostic abilities, and methods to achieve a better understanding of incident precursors as well as repair and maintenance techniques for battery-based energy systems.
Batteries are often the weak link in power systems, and tools are needed to characterize these power systems in the field. Under license from the DOE’s Idaho National Lab (INL), Ridgetop Group has extended CellSage to offer customers advanced methods for determining long term performance of battery packs used in stationary power backup systems, and electric vehicles.

CellSage: CellSage IVHM-related Runtime Licenses
CellSage can take into account more than 10 environmental and operational parameters, including battery chemistry, temperature and thermal cycling, as well as cell string topology. CellSage calculates more than 20 vital health metrics and aging effects, including state of charge (SOC), capacity loss, cell/battery conductance loss, and power fade. Originally developed by researchers at the Idaho National Laboratory (INL) of the U.S. Department of Energy (DOE), Ridgetop Group leverages the underlying CellSage technology to provide users with easy-to-understand metrics, indicators, and plots that show the battery’s capacity at any point in time.
Through a user-friendly graphical user interface (GUI), CellSage users are presented a clear picture of how the battery is aging and an accurate projection of how long the battery will last for given conditions.
In addition to its application for monitoring batteries that are already in use, CellSage can simulate ‘what if’ scenarios to weigh the impact of operational and environmental parameters on battery performance and health, aiding in the selection for the most appropriate battery for a given mission.
Ridgetop Group is currently working with industry leaders to deploy an embedded version of CellSage that will interface with new and existing Integrated Vehicle Health Monitoring (IVHM) systems. An IVHM system is intended to provide the driver and maintenance personnel information on the state-of-health (SoH), and the Remaining Useful Life (RUL) of the vehicle. Ideally, there can be a prognostic “signature” that precedes a failure in the system. This capability, in turn, allows more economical Condition Based Maintenance (CBM) practices to be supported. For an electric vehicle, this would include on-going monitoring of the battery pack, mitigating faults during the lifetime of the car, and guiding maintenance intervals based on actual degradation or wear-out mechanisms.
The potential is large as, in 2013 alone, the United States saw 96,000 plug-in electrical cars sold — representing slightly more than half a percent of the total market of 16.5 million vehicles, according to a recent Green Car Report.
CellSage Battery Modeling and Characterization Tool
Aimed at Academic and Industrial Researchers who are responsible for the development of battery power sources for diverse applications such as Electric Vehicles, Aircraft Auxiliary Power Units (APUs), Medical Electronics, and other crucial applications, the key focal points of CellSage include careful attention to thermal management. These key attributes — as well as the advantages of the CellSage Analysis product — can be seen Battery System Design Document.
Battery end-users in the vehicle, Grid ES, UAS and Aeronautical field will find incentive of this product through lower costs, reduced warranty cases and battery aging — resulting in reduced cost of replacement — and savings to battery pack costs via CellSage-aided design and lifetime analysis.
