(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
The lithium battery charging curve illustrates how the battery’s voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.
For a fully charged battery, aim for 3.65 volts. Here’s a quick reference for charging levels: When charging, use a bulk charge process first to reach the target voltage quickly. After that, a float charge is used to maintain the battery without overcharging, usually around 3.4 V per cell.
The charging shown in the graph also assumes a charge current of 0.1C amps. (The graph assumes you understand C ratings for batteries, and also understand the CC/CV charging method for lead-acid batteries e.g. this page on Battery University.) 3. Lead-acid battery voltages are temperature dependent. The graph assumes a temperature of 25 °C (77 °F).
