Battery capacity estimation is one of the key functions in the BMS, and battery capacity indicates the maximum storage capability of a battery which is essential for the battery State-of-Charge (SOC) estimation and lifespan management.
1. Understanding Battery Capacity Battery capacity is quantified in ampere-hours (Ah) or milliampere-hours (mAh). It represents the total amount of charge a battery can store and deliver at a specific voltage. A higher capacity indicates a longer duration for which the battery can power devices before needing a recharge.
The nominal capacity is defined for a new battery used under controlled conditions. The actual available battery capacity depends on the operational and environmental conditions, as well as the age and state-of-health of the battery.
The first step in battery capacity measurement is choosing the right technique. As we’ve discussed earlier, there are several methods available, such as Coulomb counting, voltage-based methods, impedance-based methods, and hybrid methods.
The formula for determining the energy capacity of a lithium battery is: For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Lead-acid batteries are commonly used in automotive applications and as backup power sources.
Two major standardized testing procedures for battery capacity are the International Electrotechnical Commission (IEC) 61960 and the Institute of Electrical and Electronics Engineers (IEEE) 1725 standards.
