R = 1 / Max charging current. Suppose the battery is 100 Ah, then the max charging current will be 10 amps, therefore, R = 1 / 10 = 0.1 Ohms. 1) Using a Single Op amp. Looking at the first high current circuit for charging …
Battery Charging Current: First of all, we will calculate charging current for 120 Ah battery. As we know that charging current should be 10% of the Ah rating of battery. Therefore, Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of ...
This method is based on the principle that current is the rate of flow of charge, and it allows you to measure the SoC of a battery with high accuracy. However, this method requires precise monitoring of the battery''s current and time, and it can be affected by factors such as temperature and aging.

The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.
Secondly, unrestricted charging at a high current eventually causes so many ions to embed into the negative electrode that the electrode disintegrates and the battery is ruined.
