Analog Devices Introduces the First Integrated Analog Controller Optimizing High-Efficiency Rechargeable Battery Manufacturing

Two-device integrated analog controller is designed for battery formation and grading systems for medium- and high-energy batteries used in hybrid and electric vehicles, energy storage and industrial tools.

  • Battery_Testing_PRAnalog Devices, Inc. (NASDAQ: ADI) today introduced two components that work together as an integrated analog controller to offer energy recycling and significant performance and cost benefits over current rechargeable battery formation and grading system solutions. The AD8450/1 precision analog front-end and controller, and the ADP1972 buck or boost PWM controller provide energy efficiency benefits in the charging and discharging cycles, both as the current is provided through a PWM controller as well as when it is directed back to the grid or to charge other cells.

    Unique to this two-device architecture is the use of analog control loops, which offer significant benefits over the current digital solution. These benefits include faster control of up to 1.5 MHz for the critical signal path, greater than 90 percent efficiency and higher accuracy over temperature. The solution is designed for battery formation and grading systems for medium- and high-energy batteries used in hybrid and electric vehicles, energy storage and industrial tools.


    Other benefits of this system solution include the ability to share lower-cost precision D/A converters and A/D converters over multiple channels. This reduces overall system cost and the size of the surrounding power components while improving the capability of switching frequencies up to 300 kHz. The addition of synchronization with phase-shifting between channels reduces input filtering. Also, the solution minimizes the need for complex coding and cuts system calibration time in half. Both synchronous and non-synchronous architectures are available. Design tools and total reference designs are provided for customers to minimize development cost and cycle.
