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.
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.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible. After the initial constant current stage, the charger then switches to a constant voltage mode.
Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm. Observing the below picture, it becomes evident that the DC power source regulates its charging voltage in accordance with the charging current limit.
