1. A system for estimating an energy range of a vehicle, comprising:
a memory storing instructions;
a hierarchy of edge/cloud servers, wherein the hierarchy of edge/cloud servers comprises:
a first level of servers configured to obtain first parameters associated with one or more driver behaviors shared among a first location and one or more different locations; and
a second level of servers configured to obtain second parameters unique to the first location and the one or more different locations; and
one or more processors communicably coupled to the memory and configured to execute the instructions to:
obtain a route of the vehicle;
deploy an energy consumption estimation model, based on a first subset of the first parameters obtained from the first level of servers, to provide an energy consumption estimate along the route from the first location to a destination;
in response to determining that the vehicle enters a subsequent location, update the energy consumption estimation model with a location model based on a second subset of the second parameters received from the second level of servers, to estimate an energy range along the route through the subsequent location; and
provide an output based on whether the estimated energy consumption is less than a current energy capacity.
