摘　　要：研究了供电动自行车使用的６Ｖ、６．５Ａｈ及１２Ｖ、１２Ａｈ两种规格的小型阀控式密封铅酸蓄电池，讨论了电池的试验结果和放电性能。这两种电池分别配用于功率为１３０Ｗ及１８０Ｗ、电压为３６Ｖ的电动自行车。电池以平均工作电流６Ａ（１２Ｖ、１２Ａｈ、２ｈ率）放电，其初始质量比能量达到３１．８Ｗｈ／ｋｇ以上，体积比能量大于１０７Ｗｈ／Ｌ。不同型号的电池已批量配置于不同功率要求的电动自行车使用，一年前配用的电池，现仍在正常运行中。Two types of portable valve-regulated lead acid batteries (6V . 6. 5Ah and 1 2V . 12Ah )for electric bikes have been investigated. The test results and discharge performance of such batteries have been dis- cussed. The batteries have been used for electric bikes with 36V . 1 30W and 36V . 1 80W motors respective- ly. For the 6V. 6. 5Ah battery , the initial weight specific energy and the volume specific energy are 30. 4Wh/kg and 88. 7Wh/L respectively , measured at the 1. 3h discharge rate. For the 1 2V . 1 2Ah battery , the initial weight specific energy and the volume specific energy are larger than 31. 8Wh/kg and 107Wh/L respectively ,measured at the 2h discharge rate. The average cycle life of the 12V. 12Ah battery is 319 cy- cles ,cycling at constant charging voltage with limited current for 6h and constant discharge current for 2h. The performance characteristics of the various types of the batteries in batches have met the requirements of the electric bikes of various powers. The investigation of continuous driving records for thousands of electric bicycles on road which have heen used in practice shows that the cycle life had reached 396 cycles for the users who pay attention to the correct maintenance of the hatteries.
