Other features include a programmable discharge alarm threshold, an I2C interface for accessing coulomb count and device programming, a Power Good output, and 8 selectable peak input currents from 5mA up to 250mA to accommodate a wide range of battery types and sizes.
If you think of a battery charge as “fuel” for your electronic system, “coulombs” are the “gas.” In this article, Jeff discusses the math, history and science behind Coulombs law. He then shares the details of his project to build a battery monitor based on ADI’s LTC4150 “coulomb counter” device.
Without any information for a newly used battery, the SOH is assumed to be healthy and has a value of 100%, and the SOC is initially estimated by testing either the open circuit voltage, or the loaded voltage depending on the starting conditions. Figure 1. Flowchart of the enhanced coulomb counting algorithm.
Unlike the OCV method, coulomb counting is independent of battery power fluctuations (which cause battery voltage drops), and accuracy remains constant regardless of battery usage.
SoC Estimation by Coulomb Counting is based on the measurement of the current and integration of that current over time. The State of Charge (SoC) of a battery cell is required to maintain it’s safe operation and lifetime during charge, discharge and storage.
However, it is very effective and provides the only accurate measurement of the Coulombs consumed from a battery. If the battery’s initial capacity is known and or specified, then the remaining capacity can be accurately determined based on the Coulomb count.
