Abstract :

Lead-acid batteries are the oldest batteries in use for domestic and commercial applications. These are discarded in a big number every year from their first life use. If these batteries can be put in second-life uses then carbon foot prints can be made lower. Now, the problem is when one goes to buy a reused battery on a corner shop, how one knows that battery is good or not for his use. Some state-of-health (SoH) methods and indicators are required which can be used in very short duration (1-5 minutes). So, the method should be fast, cheap, reliable, easy to use and should work without any history data of the battery. In this work, six methods are investigated for fast SoH evaluation without knowing the history. Two methods are already known and four are introduced in this research first time. Out of these methods, two methods are producing less than 10% error on wider range of SoC and SoH. A hybrid combination of these methods is discussed as well where disadvanatges can be neglected and advanatges can be put together.
