What are SoH ( State-of-Health) for a battery?
State-of-health (SoH) and State-of-Charge (SoC) are key quality indicators as they provide very useful data needed for the optimization of the Battery Management System (BMS).
State-of-charge and state-of-health are different parameters that can sometimes be confused. The aim of this article is to clearly define each term and explain its value and use.
The state-of-health (SoH of a battery describes the difference between a battery being studied and a fresh battery and considers cell aging.
It is defined as the ratio of the maximum battery charge to its rated capacity. It is expressed as a percentage as seen below.
Qmax/mAh= The maximum charge available of the battery
Cr= The rated capacity
Figure 2: Evolution of the SoH of a battery during aging
The discharge profile of a secondary battery is affected by its state of health. The lower the SoHSoH, the faster the battery is discharged as it is illustrated in the Figure 3 below.
Figure 3: U vs. t during battery charge and discharge cycles for different SoH
How to measure SoC and/or SoH with a BioLogic potentiostat / galvanostat or battery cycler
The SoC value is reachable by monitoring the charge of the battery (measurement of the current and the time). To this end, Galvanostatic Cycling with Potential Limitation (GCPL) technique as well as Chronopotentiometry (CP) and Constant Current (CC) techniques are suitable.
One of the ways available of determining the SoH is to know the quantity of charge Q that can be stored at a specific stage. Therefore, the EC-Lab® or BT-Lab® Battery Capacity Determination (BCD) technique can be used in this purpose.
