Quickly Configure to Test Your Next Generation Li-ion Cells

The BT2200 charge-discharge platform is cost-effective and easily configurable for Li-Ion cell formation and lifetime cell cycling. A modular design supports cells requiring maximum currents ranging from ± 6 A to ± 800 A, with up to 256 cells or channels per chassis. You can quickly deploy different channel configurations as your cell requirements change and capacities grow.

Source and sink current up to 800 A per channel
Precisely regulate voltage at the cell with a four-wire sense
Simplify programming with user channels that act as a single high power channel formed with parallel channels
Protect your cells with separate charge, discharge, and pre-charge limits

Create unique sequences of charge, discharge, rest, DCIR, and pre-charge steps
Measure Voltage, Current, Power, Amp*Hours, Watt*Hours, ΔV/Δt, ΔI/Δt, ΔV, and ΔI
Improve efficiency with Regenerative power
Control with USB, or LAN (LXI Core)

Simple to Sophisticated Li-ion Formation

When forming Li-ion cells a multistep charge-discharge process can form a high-quality solid electrolyte interphase SEI layer. Often you have to make a tradeoff between a slower multi-step process and a simpler but faster process. Sequences allow the BT2200 Series to handle simple to complex conditioning sequences.

Create up to 256 unique sequences, containing up to 50 steps each.
A step starts a charge, discharge, rest state, or a DC internal resistance (DCIR) measurement.
Add measurements and test conditions to each step.
