The Keysight BT2203B is an 8-slot charge-discharge mainframe engineered for Li-Ion cell formation and lifetime cycling validation. Operating from 208 VAC 3-phase input power, this platform accommodates up to eight BT2204B or BT2205A modules and supports 256 cells or channels per chassis. Channel current is configurable from ±6 A to ±800 A depending on module selection and paralleling configuration, with maximum voltage rated at 6.0 V per channel. The mainframe executes charge, discharge, pre-charge, rest state, and DC internal resistance (DCIR) measurement routines across up to 256 programmable sequences, each containing up to 50 steps. Real-time monitoring includes voltage, current, power, Amp*Hours, Watt*Hours, ΔV/Δt, ΔI/Δt, ΔV, and ΔI. Integrated probe-check verification and customizable stop limits protect cells during formation and cycling. Regenerative power capabilities enhance system efficiency. Control interfaces include USB and LAN (LXI Core). The BT2203B scales from compact cell testing using BT2204B modules (32 channels, ±6.25 A per channel, up to ±200 A with paralleling) to high-current applications via BT2205A modules (2 channels, ±100 A per channel, up to ±800 A with full paralleling).
