One of the first steps when designing a battery pack monitoring, balancing, and protection circuit is to choose the sense resistor. To do this, consider what are the short circuit current limit (SCD) and the overcurrent limit (OCD) as well as the voltage threshold setting used by the AFE.
4.1.5 Internal LDO In a 10s battery pack, the maximum voltage may be significantly higher than the maximum voltage of the REGSRC pin (36 V). A circuit is then required to reduce the voltage to a suitable value for the IC. The FET also dissipates the power resulting from the load current and dropped voltage external to the IC.
charging current, the power supply emulate the behavior of a Li-ion battery charger, which is constant current until the desired cell voltage is reached (usually 4.2 V), then switch to constant voltage.
By setting the current limit at the desired charging current, the power supply emulate the behavior of a Li-ion battery charger, which is constant current until the desired cell voltage is reached (usually 4.2 V), then switch to constant voltage. The power supply is then switch off once the charging current drop below the taper current.
The direction of current through the battery determines whether it is charging or discharging. The battery is trying to push current in a particular direction. If the current flows in that direction, the battery is discharging. If the current flows in the other direction, the battery is charging. It is a little bit like a spring or a clockwork toy.
It also drives the cell balancing circuit. • A microcontroller (MCU) used as a battery management controller enables configuring of the AFE’s parameters, doing the gas gauging algorithm, doing the cell balancing scheme, handling the fault, and communicating with the system outside the battery pack.
bq24780S 1
It allows battery discharge energy to system when system power demand is temporarily higher than adapter maximum power level. Therefore, adapter does not crash. The bq24780S device uses two charge pumps to separately drive N-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection.
