US 11,890,962 B1 · Electric vehicle charge determination

Abstract

A diagnostic service is selectively started at opportune times, such as when the electrical vehicle is initially plugged in. When the electrical vehicle is turned off, there may not be any messages being sent on the communication bus since most vehicle electronic controllers are disabled to conserve power. But, when someone plugs in a charger, there is a surge of bus traffic for a short period of time. The system parses through the bus traffic and looks for a particular communication bus address. The presence of this address can be used as an indicator for an opportune time to start the diagnostic service to confirm whether the electric vehicle is charging or not and to log the state of charge of the electric vehicle.

Claims18

Dependent claims

A computer-implemented method comprising:

while a diagnostic service is not running:
receiving, from an electronic controller of an electric vehicle, a plurality of vehicle bus messages via a vehicle interface with the electric vehicle;
and
processing the plurality of vehicle bus messages to identify, from the plurality of vehicle bus messages, a first vehicle bus message having a first vehicle bus message type, wherein the first vehicle bus message type indicates a potential initiation of charging of a battery of the electric vehicle;
and
in response to identifying the first vehicle bus message having the first vehicle bus message type:
running the diagnostic service configured to receive, via the vehicle interface, first diagnostic data regarding the electric vehicle;
and
confirming, using the running diagnostic service, a charging state of the battery from the first diagnostic data.
