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
State of Charge
SoC Estimation by Coulomb Counting
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
Mileage equals Wear
Authors: Dr Kotub Uddin & Nigel Taylor When we look at this picture, we see the over-simplicity of the ‘mileage equals wear’ mindset. Figure 1 shows reported SOH as a function of miles-driven for Nissan Leaf EVs. Similar distributions are reported by Myall and co-authors [1] who analysed 1382 reported SOH data points from 283 … Read more
SoC Estimation Techniques
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
