AI Customer ServiceThe charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.
The available capacity C at different discharge rates can be calculated using the following equation: (7) C = C n (I n I) k − 1 where In is the nominal discharge current. The empirical law points out that the charge delivered by the cell depends on the current. Since k>1, the greater current, the less charge delivered [32, 33].
A discharge capacity estimation method under constant current and working conditions is verified using an equivalent circuit model. Besides, the SOC is estimated using adaptive dual extended Kalman filter (ADEKF). Experimental results demonstrate that the estimation error of remaining discharge capacity is 0.0074Ah (0.336%).
At constant current discharge, W = I * U (t) dt = It * u (u is the average discharge voltage, t is the discharge time) a. Theoretical energy The discharge process of the battery is in an equilibrium state, and the discharge voltage maintains the value of electromotive force (E), and the utilization rate of the active substance is 100%.
If a battery is being charged at 5 amps and has an energy rating of 20 Ah, the C rate is calculated as: \ [ C\ Rate = \frac {5} {20} = 0.25\ C \] This means the battery is being charged at a rate that is one-quarter of its total capacity per hour.
