Abstract

A system for managing mobility of an electrically-powered vehicle. The system includes a monitoring module comprising a plurality of sensors. Each of the plurality of sensors is configured to sense the status of at least one feature of each of the electrically-powered vehicle, an environment in which the electrically-powered vehicle is residing, and a state of health of a battery of the electrically-powered vehicle. A mobility analysis module estimates mobility of the electric-powered vehicle based on the sensed status, and a telematics module displays the sensed statuses, the estimated mobility, or both. The telematics module resides on a cloud-based server.
