Battery model with robustness to cloud-specific communication problems

摘要

A vehicle may include battery cells, and a controller configured to control the vehicle based on state observation of the battery cells using model parameters calculated according to nominal parameters of the cells determined by the controller, corrected for by remote delta parameters the cells, wherein the delta parameters are received from an external computing device in response to a cell battery model related cell measurements sent to the external computing device, the delta parameters indicating corrections that improve the accuracy of the nominal parameters.
