Gauging Accuracy Comparison Between Coulomb Counting and Impedance Track Gas Gauges
The battery operated devices with their expanded features and functionality require increased power demands. The battery must provide more and more energy as well as longer run-times. The accuracy of the battery’s gas gauge is as important as the power-conversion efficiency and battery capacity. If the battery gas gauge has ±10 percent accuracy, the system only uses 90 percent of the battery’s energy to prevent loss of critical data. This is equivalent to 10 percent battery capacity, or run-time loss. However, the battery’s useable capacity is dependent upon its discharge rate, temperature, aging and self-discharge since the battery termination voltage is related to the battery impedance and discharge rates. The battery impedance is quite dynamic and is function of the aging, state of charge and temperature. This presentation will discuss the test results for the traditional coulomb counting and impedance track based gas gauge without a learning cycle over 50 cycles and through entire useful life of the battery. It is shown that monitoring battery impedance significantly improves the battery gas gauge accuracy and extends the battery runtime.

A Scientific Approach to Choosing a Battery Chemistry for a Specific Application
Choosing a battery for an application begins with a review of the application requirements. The three major areas of focus are electrical, mechanical and environmental. Within each area we review the specific requirements and prioritize them based on importance. Each of the critical parameters is given a weighting value. Individual battery chemistries are rated for the parameters chosen. These ratings are then used in a Factorial Analysis for the specific application. The batteries with the highest scores in the Factorial Analysis are next run through a Decision Tree as a sanity check to ensure that their high scores are congruent with being chosen as the battery chemistry of choice, in particular based on the most important parameters. Spider (or radar) charts, decision trees and factorial analysis data will be presented for an example based on a medical application.

Advances in Resistance Welding Technology Offer Improved Weld Quality and Reliability for Battery Manufacture
The resistance welding of battery connections and battery packs has been traditionally completed by Capacitance Discharge and AC welders. These Open Loop welders deliver the same weld energy each time with no adjustment for resistance changes due to variations in part fit-up, electrode wear, electrode position and spacing. Therefore welds are not optimized, the process is not in control and any weld fault corrective action is typically an arbitrary increase in weld current or time. Inverter technology is Closed Loop, providing dynamic feedback to the welder during the weld to ensure that the same heating effect is delivered according to the resistance of the weld. Variances in the weld set-up can be accommodated. This reduces scrap, downtime, set-up time, weld strength variance, operator dependence and offers increased weld reliability, accommodation of weld setup and capability of weld data collection. This presentation introduces inverter technology and its implementation, clearly defining the benefits with specific application examples.

Weldable, High Conductivity Cell Interconnect Materials
Interconnect ribbons between cells in power packs have traditionally used nickel ribbon. Nickel ribbon is less than ideal for this application due to its low conductivity and volatile cost. Development work at Technical Materials Inc. and at several battery manufacturers and welding equipment producers have resulted in a body of work which characterizes a variety of multi layer clad ribbons. These materials are capable of significantly increasing the current carrying efficiency of ribbon through the use of high conductivity copper and aluminum laminates. A matrix of conductivity, weldability and corrosion performance is provided for the various compositions. Also, an economic model compares intrinsic costs for nickel and several composite ribbon compositions.

Using Incremental Capacity Analysis to Probe State of Health of Batteries in Traction Applications
Probing state of charge (SOC) and state of health (SOH) of a battery is of paramount importance in battery applications, particularly for traction applications such as those in hybrid electric vehicles where duty cycles are sporadic in nature. To date, few numerical approaches are being used for SOC and/or SOH estimations in automotive applications. Recently, we began to employ a few evaluation techniques and diagnostic analyses to develop a set of reliable tools to determine SOC and SOH in several commercial Li-ion battery chemistries. In this presentation, we will discuss the application of the incremental capacity analysis for capacity fade determination and as a tool to probe the SOH with experimental test data, especially for traction applications. Several examples of how this technique can be used to determine the sources of capacity fade and quantitatively monitor the SOH will be presented.

Reliable Power Sources for Mission Critical Applications
Battery pack reliability has been neglected in academic literature and ignored by cell manufacturers and battery pack assemblers alike. The battery pack is a complicated system consisting of electronics, mechanical parts and the electrochemical cell. A rechargeable battery cell is subject to wear; it experiences a loss of capacity over time, and its end of life occurs by definition at 80 percent capacity after approximately 500 cycles. What, however, is the probability of a battery pack's failure as a whole?
As Li-ion battery packs replace sealed lead acid batteries in industrial applications, they become more complex. The number of connections between cells rises with serial-parallel topologies more rapidly than the number of cells. It is proposed that parallel strings may be used to increase reliability by providing redundancy. Yet that increases the number of parts. To numerically compare the reliability of different topologies, analytic solutions must be derived, based on developed reliability diagrams and established probability density functions. After a review of the issues and industry standards in battery reliability, Micro Power Electronics will present a comparison of the reliability of redundant parallel cell strings. The results of this investigation, analysis of redundancy options, their technical implementations, and their economic practicality, may be of interest to the battery community and of particular importance to the developers of mission critical equipment.
