Calculating Battery Charging Current. Here we should look at the C Rating of the battery; the C Rating defines at what capacity (in amps) the battery can be charged and discharged of its total capacity, which is rated in AH (ampere-hour). I have a 150 AH battery that has a C10 rating on it, so it should be: 150AH ÷ 10H = 15A.
Charging of battery: Example: Take 100 AH battery. If the applied Current is 10 Amperes, then it would be 100Ah/10A= 10 hrs approximately. It is an usual calculation. Discharging: Example: Battery AH X Battery Volt / Applied load.

The State of Charge (SoC) of a battery cell is required to maintain it''s safe operation and lifetime during charge, discharge and storage. However, SoC cannot be measured directly and is estimated from other measurements and known parameters. This leads to errors in the estimated SoC and that means it is not possible to fully exploit the full capability of the cell.
