FAQS about Methods to reduce battery discharge current

Which control method is best for battery charging and discharging?

Despite the fact that constant-current–constant-voltage (CC–CV) is the most used control method for battery charging and discharging, other methods such as FLC or MPC have shown better performances.

Which control method is used for charging and discharging lead-acid batteries?

Results and Discussion This research shows that the most used control method for charging and discharging lead-acid batteries in renewable energy systems with battery energy storage is that of CC–CV. However, this control method requires a long time to charge the battery.
