Battery cell formation & test equipment

Block diagram

Overview

Our integrated circuits and reference designs help you create high-density battery cell formation and test equipment to precisely monitor and control charging and discharging I/V profiles during battery formation and testing. Different architectures are optimized for cost and performance for different power levels.

Design requirements

Next-generation battery cell formation and test equipment designs often require:

  • High-efficiency buck/boost power supplies at the optimum level.
  • Precision-control loop of the charge and discharge process.
  • Highest level of current and voltage accuracy.
  • Maintaining system accuracy over wide temperature range.
