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

Smart Battery Development

smart battery design

Prof James Marco WMG Energy Group Significant advances have been made in recent years in our understanding of the electrochemical performance of lithium-ion batteries (LIBs), their degradation, safety, manufacturability and recyclability – in part, through innovations in experimental methods and mathematical modelling. WMG is at the heart of this research through our involvement in projects … Read more

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

Cells in Series

When connecting cells in series the negative terminal of the first cell is connected to the positive terminal of the second cell. The negative terminal of the second cell is connected to the positive terminal of the third cell. This continues until we reach the total number of cells required in series. The nominal voltage … Read more
