EVc high power multi-channel battery testers

Home :: Battery cyclers :: EVc high power multi-channel battery testers

Multi channel battery cyclers.

  • The EVc-10, EVc-30 and EVc-40: 10, 30 and 40 channel battery charge discharge cyclers.
  • High speed data-acquisition: Real time display of individual cell internal resistance.
  • Up to 5 amps/channel with multiple cut-off voltages up to 11 volts.
  • Complex charge and discharge profiles set up and displayed in real time.
  • High speed galvanostatic intermittent titration techniques (GITT): 8 μS/point enables detailed step impedance analysis (SIA). SIA is better than EIS because:
    • SIA is a transient measurement technique that provides boundary value information.
    • EIS is limited to steady state measurements.

Multi channel EVc battery cyclers are also used to recondition any type of recombination battery (NiCad, Pb-acid and nickel metal hydride).
