A battery cycler is a precision instrument that executes controlled battery cycling (charge/discharge) to quantify capacity, efficiency, internal resistance/impedance, and derive SoC/SoH. Modern platforms such as i-BEAM and Mi-BEAM deliver bidirectional source/sink with regenerative energy recovery, enabling dynamic profiles (e.g., EV drive cycles, BESS duty) from R&D to production.

Across EV, aerospace, BESS, and industrial applications, repeated battery cycling reveals capacity fade, internal resistance growth, and efficiency trends under realistic load profiles. These insights guide chemistry selection, pack architecture, thermal strategies, and BMS control while lowering lifecycle risk.
