How To Calculate Battery Discharge Time. Battery Needed is rounded to nearest whole number and is rated in AH at a 20 Hour rate. This calculator will tell you what battery size you need.
Ei is the voltage at the end of battery discharge generally referring to the voltage of the battery pack. A LiPo battery consists of multipe cells. I assume you mean the current state of charge based on the voltage.
Peukerts law is the widely used empirical equation to denote the rate-dependent capacity which illustrates an exponential relationship between the discharge current and delivered capacity over specified range of discharge currents.
Suppose we took 13 Amp for charging purpose then Charging time for 120Ah battery 120 13 923 Hrs. DISCHARGE TIME FOR EV. Given that you can estimate the remaining capacity and if you measure your current draw you can guess about how much time you have left. Homework Statement Discharge time from battery if you have a pump drawing 44 amps with 12 volts dc and a light drawing 00545 amps with 110 volts ac.
