【摘要】 研究了由264只方形MH/Ni单体电池串联组成的用于电动汽车的动力电池组。其单体电池的额定容量为100Ah,能量密度达到75Wh/kg,经过800次循环寿命测试,电池仅有10%的额定容量损失;电池组快速放电性能可以满足电动轿车加速和爬坡的要求;电池组一次充电,电动轿车以40km/h匀速行驶续驶里程超过300km。更多还原

【Abstract】 A Ni/MH battery pack for electric vehicle, assembled with 264 single rectangular cells in series, was investigated. The nominal capacity of the single cell was 100 Ah, and energy density reached to 75 Wh/kg. Cycle life of the (battery exceeded) 800 cycles with only 10% loss of the original capacity. The fast discharge ability could satisfy the requirements of acceleration and (upgrade) for the car. The electric car equipped with the battery pack could run up to 300 km continuously at the speed of 40 km/h after full charge.更多还原
