state of charge, a second estimator ( 25 ) that estimates a second state of charge on the basis of the relationship between open circuit voltage and state of charge of the secondary battery ( 14 ), and a state of charge calculator ( 26 ) that calculates a third state of charge on the...
Voltage of one battery = V Rated capacity of one battery : Ah = Wh C-rate : or Charge or discharge current I : A Time of charge or discharge t (run-time) = h Time of charge or discharge in minutes (run-time) = min Calculation of energy stored, current and voltage for a set ...
Factors that affect battery capacity are the discharging current, internal resistance, state of charge, and temperature. The higher the discharge current and temperature during charging and operation, the shorter the battery life. How can I measure battery capacity? To measure a battery's capacity,...
It would be wonderful never to have to charge a smartphone again. You're probably painfully aware that no battery lasts forever, though. This battery life calculator finds out the approximate runtime of your battery based on the following formula: Battery life = Capacity / Consumption × (1 ...

BE - The battery efficiency is the ratio of the energy retrieved from the battery, to the energy provided to the battery, when coming back to the same SOC state. Lithium-ion stays close to 90%. Lead acid batteries are lower at about 90%, and nickel-based batteries are closer to 80%....
An electromotive force calculator subtracts the polarization voltage from a non-load voltage in a state in which a charge-discharge path is open to calculate the electromotive force of the rechargeable battery. An SOC estimator estimates the SOC of the rechargeable battery based on the electromotive...
“state of charge” (SOC) or “depth of discharge” (DOD) of the battery. So experiments to determine internal resistance should be confined to loads for which there is minimal or negligible discharge during measurement. There are more complex electrical models of battery chemistry and these ...
