Batteries, as backup power sources for power system outages, have been widely used in industries such as industrial production, transportation, and communication. If the PHARPS32200000 F8-G2B9B3B6 battery fails or has insufficient capacity, it may cause major accidents, so comprehensive online monitoring of the battery’s operating parameters is necessary. One of the important indicators of battery status is its internal resistance. Whether the battery is about to fail, insufficient capacity, or improper charging and discharging, it can be reflected in its internal resistance changes. Therefore, the working condition of the battery can be evaluated by measuring its internal resistance. The common methods for measuring the internal resistance of batteries currently include:

PHARPS32200000 F8-G2B9B3B6 Density method

The density method mainly estimates the internal resistance of a battery by measuring the density of the electrolyte. PHARPS32200000 F8-G2B9B3B6 is commonly used for measuring the internal resistance of open end lead-acid batteries and is not suitable for measuring the internal resistance of sealed lead-acid batteries. The scope of application of this method is narrow.

PHARPS32200000 F8-G2B9B3B6 Open circuit voltage method

The open circuit voltage method estimates the internal resistance of a battery by measuring its terminal voltage, which has poor accuracy and even leads to incorrect conclusions. Because even if the capacity of a battery has become very small, its terminal voltage may still perform normally in a floating charge state.
