A UL 1973 Recognized Battery Management System

Nuvation Energy’s BMS is the world’s first configurable 3rd party BMS to attain UL 1973 Recognition.

In order to gain commissioning approval in most jurisdictions, battery energy storage systems (BESS) must be listed in accordance with UL 9540, the Standard for Safety of Energy Storage Systems and Equipment. Within that energy storage system, battery stacks and electrical and control equipment must meet a range of other specifications to show they have passed their own respective safety evaluations.

Within a UL 9540 listed BESS, the battery stacks must be certified to the UL 1973 standard, ANSI/CAN/UL Batteries for Use in Stationary and Motive Auxiliary Power Applications. A battery management system that has been tested and approved by UL attains the “UL Recognized” designation. A UL 1973 Recognized BMS greatly reduces the UL 1973 certification effort. 

Nuvation Energy’s G4 BMS was recognized to UL 1973 through a path that included being evaluated to the UL 991 and UL 1998 standards for hardware and software respectively. These standards are recognized in the USA and Canada. The G5 BMS is UL 1973 Recognized through a path that included CSA, UL, and IEC standards. These standards are recognized in the USA and Canada as well as many jurisdictions in Europe and internationally. The G5 BMS is also CE conformant, a requirement in most European countries.
