摘要

The VRLA batteries for HIMR (Hybrid Inverter-controlled Motor & Retarder system) buses have beenrndeveloped since 1993, and already used with a lot of buses in the field. Actual life performances of thernbatteries were 2 to 3.1 years in the field use. The following results were found through the bench tests andrnthe field uses of the batteries:rn1. Contrived bench test was suitable method to evaluate sulfation phenomenon that often occurs at thernlead-acid batteries for HEVs.rn2. Capacities of the batteries were decreased conspicuously at the early stage and the last stage of its fieldrnlife, but the capacity losses of the medium stage were in a plateau state.rn3. Capacity loss at the early stage of the field mainly depended on occurrence of the negative plate sulfation,rnalthough conspicuous capacity decrease at the end of life was caused by the positive grid corrosion.rn4. Progress of the grid corrosion completely depended on the used period, and the corrosion amountrnobtained by the bench tests met to the field data.rn5. Open voltage of the battery increased at the early stage, but it gradually decreased during the field life.rn6. The voltage at 5 second during the high-rate discharge that corresponds with required current for HIMRrnlittle declined at the early stage, but the voltage decline became larger obviously at the last stage.rnBased on the database obtained through these experiments, it was found that estimating for the usablernperiod of the batteries is possible from the relations between used conditions (e.g. the period and thernups-and-downs) and the voltage at 5 second during high-rate discharge. And we have succeeded inrndevelopment of new VRLA battery for HIMR bus, which longer life performance can be expected, byrnimprovement of the grid corrosion resistance and adoption of new additive formula for the negative plates.
