Research on measuring method of ohmic resistance of lead-acid battery at the beginning of charging process

及时、准确地掌握铅酸蓄电池的性能参数,对于铅酸蓄电池的维护保养具有重要作用。蓄电池内阻是反映蓄电池性能状态的重要参数,但无法根据蓄电池全内阻对蓄电池的荷电状态和寿命进行可靠的估测。曾有文献通过实验证明,铅酸蓄电池欧姆内阻与蓄电池荷电状态的对数之间存在线性关系。基于此,本文对铅酸蓄电池在充电初始时刻欧姆内阻进行检测,从而为蓄电池的荷电状态和性能状态的实时监测提供可靠的数据支撑。

Mastering the capabilities and parameter timely and accurately has plays the important role in the maintenance of lead-acid battery. Internal resistance of lead-acid battery is a significant parameter reflecting its capabilities and states, but it is difficult to estimate the state of charge and state of health of lead-acid battery based on its internal resistance. It has been proved that ohmic resistance is linear to the logarithm of state of charge of lead-acid battery. Base on this point, the paper has proposed a way of measuring the ohmic resistance of lead-acid battery at the beginning of charging process, which providing the data to monitor the state of charge and maintenance.
