摘　　要：分析了电控液驱车辆储能元件——气囊式液压蓄能器的工作过程并建立了相关的数学模型,对液压蓄能器的特性参数(有效容积、比能量、比功率以及效率等)和能量转换效率进行了计算和讨论。对蓄能器和蓄电池在比功率和能量转换效率等方面进行了比较,提出了改善液压储能元件特性以及获得高效率的技术措施。The operating process of the bladder accumulator was analyzed to the mechanism of energy accumulation and release process and set up the correlation mathematical model of the bladder accumulator, the factors affecting efficiency for the bladder accumulator was discussed. And the characteristic parameters （i. e. effective volume, specific energy, specific power and efficiency） and the calculation method of energy for the bladder accumulator were explored. The characteristics of the bladder accumulator were compared with another energy storage elements of the hybrid electric vehicles, in result, the bladder accumulator have advantages in specific power and transfer efficiency. The measures were taken to improve characteristics of the accumulator, the conditions were put forward to gain the maximum efficiency and energy.
