Separating charge and discharge in measuring next-generation car batteries

Lithium ion phosphate batteries are widely used to power the batteries in electric cars, but, unlike the amount of gas in a fuel tank, their state of charge can’t be measured directly by a physical quantity. Instead, they use an algorithm based on measurements of battery voltage and current, which are in turn influenced by conditions such as weather, electrovoltaic state and traffic conditions. However, the algorithms currently used to measure state of charge each carry drawbacks when used in real-time applications. —> Read More
