This paper + presented the design of a constant-current/constant-voltage charging control strategy for a battery cell using the so-called cascade control system arrangement with the adaptation of the battery charging current based on the open-circuit voltage (OCV) parameter estimation.
What is charge voltage?
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.
What is a good charge current for a battery?
(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.
How does a battery charge at a constant voltage?
When charging at a constant voltage, the battery's voltage is maintained as the charging current gradually decreases towards zero as the battery nears full charge. By controlling the voltage between the battery terminals, this method protects the battery from being overcharged. iii.
What is constant-current charging?
Constant-current charging entails sending a constant current to the battery during the charging process. The charging rate remains constant as the battery voltage increases. When the battery voltage is low, this method is frequently utilized in the early stages of charging. ii.
How does the internal resistance of a battery affect the charging process?
The internal resistance of the direct current (DC) battery plays a crucial role in the charging process by causing voltage drops, power losses, and affecting the charging speed and efficiency. As shown in Fig. 6 (d), the internal resistance of a battery varies constantly during the charging process.
