State of Charge Estimation
For the battery system, we use measurements of the current into or out of the cell and open circuit voltage of the cell. Current measurement = speedometer. We can constantly measure the current leaving or entering the battery, then multiply the measured current by a time interval to get the total number of coulombs that have left the cell

How to Design a Battery Management
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.
20.1: Current
Electric Current. Electric current is defined to be the rate at which charge flows. A large current, such as that used to start a truck engine, moves a large amount of charge in a small time, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge over a long period of time.
