To control the discharge current you need to make a constant-current load, which is usually done with a powerful MOSFET, current-sensing resistor, and a feedback amplifier.
Or is the discharge current from batteries dependent on the load? Discharge current from a battery is DETERMINED by load, not just "dependent". To control the discharge current you need to make a constant-current load, which is usually done with a powerful MOSFET, current-sensing resistor, and a feedback amplifier.
The model presents Battery charging/discharging Control implemented in a case study that involves a DC bus (with a constant voltage), battery, a common load, and a bidirectional two-switch Buck-Boost DC-DC converter. 2- the other is for Current control of battery.
To "monitor" a discharge current, you need to insert a current monitor into discharge loop, usually a small-value shunt resistor connected to a specialized differential amplifier, like INA199 or ZXCT1109. My question was more into controlling/setting rather than monitoring the discharge current.
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.
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.
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.
