The maximum charging current for a 100 Ah, 12V lithium battery is around 20 Amps as a general rule.
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
(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.
When a battery is fully charged, the charging current drops to 0.1C. The circuit switches to constant voltage charging mode once the voltage achieves its maximum, charge cut-off voltage. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage.
Several factors, including the battery capacity and charging rate, affect the battery charging current. The larger the battery capacity, the higher the charge current typically is. Likewise, the higher the charging ratio, the higher the charging current and the shorter the charging time.
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
Guide: Maximum Charging Current & Voltage For 12v Battery
As a rule of thumb, the minimum amps required to charge a 12v battery is 10% of its full capacity but the ideal charging current should be between 20-25% of the battery''s capacity. For example. if you have a 12v 100Ah battery then you''ll need a minimum of 10 amps and a maximum of 20-25 amps to recharge your battery.
