State of charge (SoC)

Reliable estimation for automotive and mobility

Entroview provides a software solution tailored for automotive and mobility, delivering less than 1% SoC error, ensuring vehicle autonomy, and extending battery lifespan by reducing the typical 6% loss in usable capacity.

“Imagine a bucket where the water level stays flat, whether it’s almost full or empty”

LFP batteries have a similar problem—it’s hard to tell how much charge is left because the voltage barely changes. This can lead to inaccurate estimates of how much energy you have left, which impacts performance. Think of electric vehicles like the Renault 5, where this precision is crucial to arrive at destination.

The problem

Traditional SoC estimation methods, like OCV (Open Circuit Voltage) or Coulomb Counting, lack precision due to sensor inaccuracies and misestimations of the initial charge state. These errors often lead to a +/-3% SoC deviation in large battery packs, resulting in a 6% loss in usable capacity, which translates to ~$850 in wasted battery potential for a 100kWh EV.
