Unico’s new battery cell formation and test channels for electric vehicles

March 14, 2024

Unico, a provider of EV test solutions, has introduced the BAT300 Series at the International Battery Seminar.

Designed for test applications that prioritize cost-effectiveness and flexibility over ultra-high precision, the BAT300 Series is based off the Unico IDAC power platform and offers exceptional performance, efficiency and versatility at a significantly reduced cost. Unico’s latest offering is a compact, all-in-one solution (480VAC to DC) that minimizes energy consumption while maximizing testing efficiency.

Key features of the BAT300 Series include:-Industrial-grade reliability, exceptional efficiency, and standard performance and accuracy, all offered at an affordable price point.-Ultimate flexibility by supporting from one to thousands of channels for multiple applications.-Channels can be application specific, for example, to age the cells for characterization in the cell test application, provide a voltage and current source for the formation application, and perform basic end-of-line checks for the manufacturing application.-Basic cell test requirements such as remote voltage sense, temperature measurement for the cell, calibration, and DC contactor control can be included.-Ultra-compact design with ultra-high efficiency and bi-directional capability, enabling energy that is discharged to return to the AC grid.

The innovative novel power electronics topology includes in each channel:-The 480VAC AC to DC conversion-The channel-to-channel isolation-The DC control of the output-All in a single power stage

This innovative technology is ideally suited for cell formation in gigafactories, as well as for aging and functionality testing in R&D laboratories, and end-of-life (EOL) activities in cell/module manufacturing lines.

The product is ready for demonstration purposes with the first deliveries this summer.
