Abstract
In a method and apparatus for use with an electric vehicle in an inactive state, when a signal from a battery management system indicates that a battery pack has an electrical isolation fault, a signal is transmitted through a transmitter that includes information corresponding to the existence of the fault.
Claims20
An electric vehicle, comprising:
- a body supported by a plurality of wheels;
- at least one electric motor disposed so that the at least one electric motor drives the plurality of wheels;
- at least one battery pack in selective electrical communication with the at least one electric motor;
- a battery management system configured to output a first signal that includes information identifying whether the at least one battery pack has an electrical isolation fault;
- a transmitter;
- and
- a computer system that is in operative communication with the battery management system and the transmitter and that is configured to execute program instructions when the electric vehicle is in an inactive state, so that, upon detection that the first signal indicates that the at least one battery pack has an electrical isolation fault, the computer system transmits a second signal to a remote party through the transmitter that includes information corresponding to the existence of the electrical isolation fault indicated by the first signal.

A method of managing operation of an electric vehicle, comprising the steps of:
- providing
- a body supported by a plurality of wheels,
- at least one electric motor disposed so that the at least one electric motor drives the plurality of wheels,
- at least one battery pack in selective electrical communication with the at least one electric motor,
- a battery management system configured to output a first signal that includes information identifying whether the at least one battery pack has an electrical isolation fault, and
- a transmitter;
- and
- while the electric vehicle is in an inactive state, upon detection that the first signal indicates that the at least one battery pack has an electrical isolation fault, transmitting a second signal to a remote party through the transmitter that includes information corresponding to the existence of the electrical isolation fault indicated by the first signal.
