Field-Rugged Design

UET’s breakthrough electrolyte has been rigorously tested for several years and enables a unique set of compelling field characteristics:

  • Cycle life agnostic exceeding 10,000 cycles
  • SOC agnostic providing 100% capacity utilization over 20 years
  • Charge agnostic from partial opportunity charging to extreme ripple currents
  • Discharge agnostic with system flexibility from fractions of seconds, to 15 hours
  • Temperature agnostic operation from -40°C to +50°C (-40°F to +122°F)
  • Location agnostic from sea level to 10,000 feet (3km)

The Uni.SystemTM integrates the abuse tolerant UET electrolyte; a state-of-the-art containerized design derived from multiple decades of design experience among the UET team; mature large-scale stacks with more than 7 years of field deployment and over a dozen systems in the field; and optimized power electronics and controls at each system level (from cell to site).
