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.
