Summary
Energy storage devices, especially batteries, have become critical for several industries including automotive, electric utilities, military and consumer electronics. With the increasing demand for electric and hybrid electric vehicles and the explosion in popularity of mobile and portable electronic devices such as laptops, cell phones, e-readers, tablet computers and the like, reliance on portable energy storage devices such as batteries has likewise increased. Because many of the systems these batteries integrated into are critical, there is an increased need for an accurate in-situ method of monitoring battery state-of-health. Over the past decade the Idaho National Laboratory (INL), Montana Tech of the University of Montana (Tech), and Qualtech Systems, Inc. (QSI) have been developing the Smart Battery Status Monitor (SBSM), an integrated battery management system designed to monitor battery health, performance and degradation and use this knowledge for effective battery management and increased battery life. Key to the success of the SBSM is an in-situ impedance measurement system called the Impedance Measurement Box (IMB). One of the challenges encountered has been development of a compact IMB system that will perform rapid accurate measurements of a battery impedance spectrum working with higher voltage batteries of up to 300 volts. This paper discusses the successful realization of a system that will work up to 50 volts.
