Testing was performed on both laboratory bench packs and in vehicle packs. Pulsed current type algorithms were developed in-house and optimized for each battery pack. The packs were life cycled in a partial state of charge (PSOC) mode. It was found that a 70 to 80% charge return could be accomplished, starting from an initial 20% SOC, in a range of 13 to 17 minutes at 3C to 4.6C charge rates. Fast charging of selected lead acid batteries has shown the favorable capability of extending daily EV range without a significant reduction in cycle life.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Arguments are made in support of the theory that low or reduced separator saturation leads to escalating oxygen recombination rates in VRLA, which in turn elevates the pack operating temperature and results in increased corrosion and electrolyte dryout. A method to estimate the charge acceptance based on thermal data is also described.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

In addition, primary and secondary zinc-air cells many with substantial amounts of manganese dioxide in the cathode are becoming more common in consumer use. The gain in the past fifteen years in the carbon zinc cells approaches fifteen percent and that in alkaline cells-twenty percent. None the less the progress in zinc-air cells is most impressive as more and more commercial, compact designs appear for special purposes. These cells can produce more service than lithium cells of the same size. Finally the commercial presence of small secondary alkaline zinc-manganese dioxide cells continues. These cells are able to compete on a primary basis on heavy loads and much more obviously as rechargeable cells.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Improved charge algorithms for valve regulated lead acid batteries 改进阀控铅酸电池的充电算法

Olson","doi":"10.1109/BCAA.2000.838406","DOIUrl":"https://doi.org/10.1109/BCAA.2000.838406","url":null,"abstract":"The cycle life obtained from valve-regulated lead-acid (VRLA) batteries is strongly influenced by the manner in which they have been charged over their lifetime. Although VRLA batteries initially behave similarly to their flooded counterparts, that behavior changes as the batteries age and the oxygen generation/recombination cycle begins to dominate at near 100% full charge. This means that an increasing portion of the applied charge is consumed in the recombination cycle and that more and more overcharge must be applied to maintain full capacity. The overall result is that the battery heats up because of increased overcharge and oxygen generation. Conventional charge approaches attempt to deal with rising temperatures by lowering the current during the overcharge phase. However, this approach does not ultimately prevent capacity loss, and a battery charged thusly typically will yield 200-300 cycles to 50% of initial capacity. The main failure mode appears to be undercharging of the negative plate, not positive-plate corrosion. Two approaches, called partial state of recharge (PSOR) and current interrupt (CI) were successful in extending battery life. PSOR uses nine limited recharge cycles followed by a tenth cycle using 120% charge return. The best PSOR cycle life to date is 1160 cycles to 50% and 800 cycles to 80%. CI uses a high current in the overcharge applied discontinuously to control battery temperature. CI effectively maintains negative-plate capacity, with an Optima group 34 deep-cycle battery yielding 415 cycles to 80% initial capacity and 760 cycles to 50%.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

The condition of the negative electrode, from both new and real-time aged product, has been carefully examined by both electrochemical measurements of the product and also by analyzing the morphology and crystallography of the plates. The condition of the positive grid has also been examined to determine the extent of corrosion. In conclusion, this paper demonstrates that by using a high purity VRLA technology, which has been commercially available for 25 years, it is possible to far exceed 2 years of reliable service. Properly designed batteries using this technology have been proven to deliver greater than 13 years in real-time float service.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.
