浅析蓄电池内阻对一致性的影响

在蓄电池生产过程中,电池内阻已经成为其性能的一个标志。两只电池虽然初始容量相同,但如果内阻不同,充电时产生的热量就会有差异,导致电池的失水速率不同。随着电池循环次数的增加,容量随循环衰减的速度也就不同,容量的差异就会越来越大,最终导致电池落后。在配组时检查其内阻可以减缓蓄电池的落后进程。

Impact of internal resistance on the consistency

The internal resistance of a battery is a criterion of its performance during the manufacturing process of battery.If two batteries have the same initial capacities,but have different internal resistances,the heat generated during charging batteries will be different,resulting in different rates of water loss.The decay rate of batteries' capacities will be different with cycling,then the difference of capacities will be increased,and eventually one battery will fall behind.The internal resistance as a crite...
