Sources of Error with the Coulomb Counting Method

SoC definition for Samsung SDI 94Ah cell

It is really important to understand the sources of error with the coulomb counting method as this forms the backbone for most SOC estimation algorithms. SoC Estimation by Coulomb Counting is based on the measurement of the current and integration of that current over time. There are five main sources of error with the coulomb … Read more

Remaining Useful Life

What is Remaining Useful Life (RUL)? Remaining Useful Life (RUL) is a key function declared by the battery management system. As per the title it gives you the remaining predicted lifetime of the battery based on its usage and degradation to the failure threshold [1]. It represents the period from the observation to the end of life … Read more

Battery Management System

Batteries are the heart of an Electric Vehicle but the Battery Management System is more like the brain which keeps the Heart pumping out electricity to the Motor safely and at required output. Electric

SoC Estimation by Coulomb Counting

SoC definition

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, SoC cannot be measured directly and is estimated from other measurements and known … Read more

SoC Estimation Techniques

SoC from OCV lookup

There are a number of SoC Estimation Techniques and this article will be just an initial introduction. 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, SoC cannot be measured directly and is estimated from other measurements and known parameters. … Read more
