Current limiting when charging gel batteries?
Yes it will likely try to charge at 30V, but the low current, due to the added resistance, is typical of the battery current as it becomes close to being fully charged so that won''t bother the charger. As the battery voltage reaches 30V or so, the charge current will then naturally taper off to a trickle value.
6 FAQs about [Battery charging current limiting module principle]
What is the relationship between charging voltage and battery charging current limit?
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.
What is the current limit phase of a battery charger?
During the current limit phase, the charger must limit the current to the maximum allowed by the manufacturer (shown as 1c here) to prevent damaging the batteries. About 65% of the total charge is delivered to the battery during the current limit phase of charging.
How to calculate battery charging voltage?
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.
What happens if a battery reaches 1C current limit?
During the 1c current limit charge phase, the battery reaches 4.2V with only about 65% of charge capacity delivered, due to the voltage drop across the ESR. The charger must then reduce the charging current to prevent exceeding the 4.2V limit, which results in the decreasing current as shown in Figure 5. FIGURE 6. BATTERY EQUIVALENT CIRCUIT
What is a battery current control system?
The current control system is commanded by a superimposed battery voltage controller aimed at bringing the battery terminal voltage to the fully-charged state while also limiting the maximum battery charging current.
How does a battery charge cycle work?
The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
