WebApr 14, 2024 · This starts reducing the moment the battery is put to use. This usage and life is termed as State of Health (SOH) and is a figure of merit of the battery’s usability and life. SOH’s unit of measurement is the percentage (0-100%). Once a battery is deployed, BMS can measure certain parameters and calculate the SOH. WebMay 31, 2024 · Determining the level of battery health is crucial in terms of predicting the remaining power and reserve, as well as ensuring the safety of the end-user. If the battery has lost 20% of its capacity (SoH 80%), it should be replaced. The SoH parameter is defined as the ratio of the current battery capacity to the original capacity in percent. State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions. The units of SoH are percent points (100% = the battery's conditions match the battery's specifications). Typically, a battery's SoH will be 100% at the time of manufacture and will decrease over time and use. However, a battery's performance at the time of manufacture may not meet its specification… how many likes do you get a day on hinge
