What does SoC mean on a battery?

SOC is a percentage and helps users determine when the battery needs to be charged. SOC ranges from 0% (a complete discharge) to 100% (a full charge). If a battery has an SOC of 20%, this means that the battery has about 20% of its charge left, and it is 80% discharged.

Are battery monitor measurements accurate?

In a legacy BMS, which relies heavily on Coulomb counting or simplistic cell models to estimate SOC, battery monitor measurement accuracy is the leading source of deviation in SOC estimation. This has driven battery pack designers to search for the most accurate cell voltage measurement capability.

How to choose a BMS for lithium batteries?

If you are looking to build safe-high performance battery packs, then you are going to need to know how to choose a BMS for lithium batteries.
