Battery Observability is about the limit of what is possible to know about a physical battery system and has two key dimensions. The first is the quantity and quality of sensors that collect data on measurable quantities like voltage, current, and temperature. A better, often more expensive, sensor array leads to better observability. The second dimension is the ability to estimate quantities that cannot be measured, like SoC and SoH. The quality of both the algorithms and sensors has a significant impact on the accuracy of the estimate. Observability can be improved with better software, better sensors, or both.
