Battery parameters are important characteristics and attributes that determine a battery's performance, state of battery, and behavior. These parameters give important information about the battery's capacity, health, current condition, and practical constraints. An overview of some important battery parameters is discussed in Table 2 [24, 25, 26].
The state of charge (SOC), state of health (SOH), internal resistance, and capacity are associated with battery characterizations and its life . These factors play a key role in estimating real-time electric vehicle applications. In battery management systems (BMS) and control algorithms, battery parameter estimation is crucial .
Battery parameter estimation is fundamental to BMS, which ensures the safe and efficient operation of battery systems . Estimating parameters such SOC, SOH, and internal resistance allows BMS to make informed decisions regarding battery charging, discharging, and overall system control .

Why are batteries measured in Volts and not Watts? : r/askscience
A battery on its own is just a storage unit, i.e. it is not delivering power or receiving power, so it is measured by its electric potential, measured in volts. You cannot directly connect the two, because the power delivered by an electric potential depends on the current generated (P = V*I), which depends on the resistance of the circuit formed (I = V/R).
