Battery Impedance Evaluation System

Perform stable impedance evaluation under various temperature conditions

Impedance measurement is one of the methods for evaluating the basic characteristics of secondary batteries. Impedance measurement provides more accurate analysis by the measurement under the same temperature which batteries are used, and it is effective for evaluating degradation of batteries.

The Battery Impedance Evaluation System re-creates an environmental condition in the test area, which a secondary battery is exposured. The charge-discharge operation and the impedance measurement are carried out automatically with accurate measurement data.

  • Impedance is measured from low temperatures of -20°C to high temperatures of +80°C, and battery degradation and frequency characteristics are evaluated.
  • Simply place the battery into the special holder designed for easy connection and disconnection of the power supply unit, and start evaluation testing.
  • Evaluates multiple batteries at the same time.
