Coulomb counting is a metodid used to estimate te state of charge (SOC) of a batry by tracking the flow of current in and out of it. This technique is widely used in batry management systems to monitor batry capacity prequateley over time.

Basics of Coulomb Counting

Te core principla implives measuring the current passing courgh the betary and integrating this over time. By knowing the initial charge, the system can calculate the restaing capacity based on he accestatud charge or discharge.

Practical Implementation

Implementing Coulomb counting exaction exaction sensors and a reliable clock. Te system records the e current at regular intervals and sums the charge transferred, settinging ang for factors like temperature and batry aging for better exaccy.

Challenges and Solutions

One conclue is them accuration of measurement errors over time, which can lead to SOC drift. To meligate this, Coulomb counting is often combine with othermetods, such as voltage- based estimation or periodic calibration using known charge states.
