Smart vehicle reflash with battery state of charge estimator

A server system for updating electronic modules installed in respective vehicle models in a vehicle fleet, comprising:

• a database of update files maintained in the server system for reflashing of respective electronic modules;
• a depletion database maintained in the server system storing data defining a respective current draw by the electronic modules involved in each respective reflashing and defining a respective reflash time associated with each respective update file when applied in each respective vehicle model;
• a controller in the server system coupled to the databases and configured to A) receive pedigree information from a particular one of the respective vehicles to the server system, B) identify relevant update files and corresponding current draw and reflash time data for outdated modules in the particular vehicle in response to the pedigree information, C) send the relevant update files and corresponding data to the particular vehicle model, D) receive a report of an actual reflash time from the particular vehicle model after applying a respective update file, E) receive a report of an actual current draw from the particular vehicle model after applying the respective update file, and F) updating the current draw and reflash time data maintained on the server system in response to the reported actual reflash time and actual current draw.
