A battery fuel gauge can be implemented in a variety of ways. The most popular is to derive the remaining battery capacity from the battery voltage. This method has advantages in that it is easy to implement and relatively low in cost, but it does have one major drawback: It is relatively inaccurate. Battery voltage has, at best, an inconsistent relationship to battery

As the fuel gauge gives a lot of information, this information can be used as a redundancy in the system in order to provide a second layer of protection. As I told you before, for example, the equivalent series resistance-- if it increases a lot in one cell, we can know that something bad is happening.
Batteries are everywhere, improving our daily lives. We offer highly accurate gauges for applications ranging from smartphones, notebooks and power tools to vacuums and energy storage systems (ESS). There are gauges equipped with integrated protection or for higher voltage applications up to 15 cells in series.
You have a very accurate, but your fuel gauge is not that-- if your fuel gauge is not accurate-- I mean, the one that is performing all the calculations is the one that has to be very, very precise.
Fuel gauges are typically deployed in intelligent, autonomous batteries called smart batteries. Because development effort is considerably less with integrated fuel gauges, this approach is well suited for applications that demand a quick time to market. One such fuel gauge, the DS2780, allows the host to read the SOC using the 1-Wire bus.
Fuel gauging of chargeable battery cells is a complex task due to the many interdependent parameters that influence cell capacity. Simple methods of measurement, therefore, deliver inaccurate results that are adequate only for non-critical applications.
