Traffic UPS


Blue Earth Energy Power Solutions partners with Nickel-Zinc to develop the solution to the traffic control industry’s battery backup system problems

Blue Earth EPS (BE EPS) is a division of Blue Earth, Inc. and is the energy power solutions division for battery backup systems.

Leveraging PowerGenix’s nickel-zinc technology, BE EPS’ patent-pending UPStealth™ is the lead-acid free, energy efficient, intelligent digital battery backup management system designed to power signalized intersections during loss of utility power.

A major challenge with nearly all traffic industry transportation cabinets is limited or no space available for installing a Battery Backup System (BBS). As a result, most agencies are forced to pay for an expensive external enclosure or piggy-back cabinet to provide battery back-up for their cities. Furthermore, the lead-acid batteries currently used in BBS and other UPS systems are large, heavy, and contain dangerous chemicals that require special handling. Most lead-acid BBS also need costly routine maintenance 2-3 times per year.

Blue Earth Energy Power SolutionsUPStealth™ was designed as an alternative to lead-acid battery backup systems, enabling Blue Earth EPS to provide its customers with an environmentally friendly product that is completely recyclable with no hazardous out-gassing, corrosion, flammable or explosive characteristics. 

BE EPS spent a considerable amount of time and research choosing the best rechargeable battery chemistry for the Traffic Industry. BE EPS ultimately selected NiZn for its:

  •  High energy density and performance
  •  Environmentally friendly material
  •  Durability and overall safety of the cell
  •  Lifespan, which should last twice as long as Lead Acid Batteries

pgx-upstealth3The UPStealth™ battery backup system can be formed in various configurations that allow the intelligent battery to bend around corners and fit into spaces that cannot be accessed by traditional battery backup systems.

Compared to lead-acid battery backup systems, the UPStealth™ energy power solution’s has a lower cost of ownership, requires less maintenance, performs several years longer, and eliminates costly hazardous disposal issues and in most cases provide twice the energy in less space.

The UPStealth flexible panels fit into the Transportation Cabinet’s unused space between the internal rack and the outside shell of the cabinet. The “332-170” battery panels series configuration takes up no rack space, thus eliminating the need for an expensive external cabinet 

In addition, for NEMA Cabinet users, the UPStealth Shelf Panel can be mounted on the top or underside of the NEMA cabinet shelf. A rack mount version is also available for other Transportation Cabinets.
