Analog Devices' Integrated Precision Solution Enables Safer and Up to 50% More Efficient Battery Manufacturing

Analog Devices » AD8452

Analog Devices introduced a precision integrated analog front end, controller, and pulse-width modulator (PWM) for battery testing and formation capable of increasing system accuracy and efficiency in lithium-ion battery formation and grading. Compared to conventional technology, the new AD8452 provides 50% more channels in the same amount of space, adding capacity and increasing battery production throughput.

Analog Devices - AD8452

The AD8452 uses switching technology that recycles the energy from the battery while discharging and delivers 10 times more accuracy than conventional switching solutions. The higher accuracy allows for more uniform cells within battery packs and contributes to longer living batteries in applications such as electric vehicles. It also enhances the safety of manufacturing processes by providing better detection and monitoring to help prevent over and undercharging which can lead to battery failures.

The AD8452 delivers bill of material (BoM) cost savings of up to 50% for charging/discharging boards and potential system cost savings of approximately 20%. System simulating demonstration boards will be available and can enable lower R&D engineering cost and shorter time to market for test equipment manufacturers.
