Understanding The Battery Charging Modes: Constant Current and Constant Voltage Modes 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.
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.
Importantly, the DC power source ensures that it does not exceed the maximum battery voltage limit during this adjustment. The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.
Under and over discharge protection, setting of the battery voltage and current profiles, and implementing battery charging control techniques can be achieved by using an appropriate control system. Conventional configurations for battery charging circuits, explained before, can be used for the battery charger. Inductive contactless charger scheme
Battery charging circuits are power electronic converters in nature. Therefore, EMC rules and regulations exist that apply to the battery charger circuits.
Normally high discharge rate (C-rate) batteries can be fast-charged. For example, when the charging voltage is 5V and charging with 1C, it can be fully charged in 1 hour. If it is a 1000mAh battery, 1C means the charging current is 1A; for a 2000mAh battery, 1C means the charging current is 2A, and so on.
The charging rate is controlled by the DC value of charging current; thus, charging time of the battery can be controlled by the duty cycle: Fig. 6 Current profile of the …
