Abstract
Improvements in the field of electric vehicles (EV) are provided, including EV telematics estimation. Prior techniques estimate a state of charge (SoC) of a battery of an EV based on electrochemical measurements of the battery, such as battery terminal voltage, battery current, or cell temperature. The present improvements estimate SoC or other parameters based on non-electrochemical variables, referred to as exogenous information, meaning information other than electrochemical parameters of the battery. Example exogenous information includes battery type, and battery capacity, vehicle type or load, driver behaviour, weather conditions, or traffic or road conditions. Exogenous information may be used to enable more accurate estimations of EV SoC by EV related systems.
