The output of this configuration is controlled by adopting a PWM feedback control. Figure 26 shows the simplified block diagram of this configuration with its control system. Flyback, forward, push-pull, half bridge, and full bridge are the main types of this battery configuration.
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.
The control system can in turn drive a solid-state switch, such as a MOSFET placed in the path of the charger terminal, to disconnect the charger from the battery. Such a mechanism involves no blown fuses and allows the charger to be reused immediately after correcting the battery terminal polarity.
Control algorithms dictate the operational parameters of a BMS, influencing how the battery is charged and discharged to optimize performance and safety. This is the central processing unit of a BMS, executing control algorithms and managing data from various sensors to maintain the battery’s health and efficiency.
This protection mechanism ensures that the current flowing into the battery is kept below a maximum permissible value. It is quite clear that one cannot push current into a load unless the impressed voltage is set to a value such that the required current flows against the load resistance.
So, temperature control in battery management systems is mostly implemented using simple on/off control with varying time intervals, depending on how close the temperature is to the limiting value. Reverse polarity protection ensures that unintended high current does not flow into or out of the battery.

For your 9.6V battery you get current less than 1A (1C rate) if the resistance is more than 9.6 ohms. If resistance is less than 3 ohms you are probably discharging your battery at too high a rate. Ground the output with a current sense resistor and use a solenoid or relay as the inductor and it is similar to the original circuit above.

Output Voltage and Current Waveforms. Above are the output voltage and current waveforms of a chopper circuit. From the voltage waveform, it can be seen that during the period of T ON the load voltage V0 is equal to the source voltage Vs. But when the interval T OFF occurs, the DC voltage step downs to zero, thus making the load short-circuited.
