pack amperage and discharge capacity while connecting cells in series increases pack voltage. As an example, a 24V lithium-ion battery pack typically has six cells connected in series. Many battery packs have built-in circuitry used to monitor and control the charging and discharging characteristics of the pack.
The AFE provides the MCU and fuel gauge with voltage, temperature, and current readings from the battery. Since the AFE is physically closest to the battery, it is recommended that the AFE also controls the circuit breakers, which disconnect the battery from the rest of the system if any faults are triggered.
This is also applicable to self-discharge at the anode side. Assuming the kinetics remain unchanged with constant slope values, the self-discharge current will increase from I LS,c to I HS,c (the uppercase S stands for SoC while the lowercase c represents cathodic reaction) at the cathode side, as well as I LS,a to I HS,a at anode side.
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. To "monitor" a discharge current, you need to insert a current monitor into discharge …
Use the appropriate charger recommended by the battery manufacturer. 3. Discharge to a Safe Level (Optional): If you plan on storing the batteries for an extended period, consider discharging them to around 40-60% of their capacity.
