Abstract
Testing or diagnostics are performed on an electric vehicle. The vehicle is operated and current flow through a system of the vehicle is monitored. A voltage related to the system is also monitored. Diagnostics are provided based upon the monitored voltage and the monitored current.
Claims44
A method of testing an electrical system of an electric vehicle, comprising:
- operating the electric vehicle;
- coupling to a databus of the electric vehicle;
- monitoring data on the data bus and retrieving information related to current flowing into the system of the electric vehicle during the step of operating;
- monitoring data on the databus and retrieving information related to a voltage of the system during the step of operating;
- and
- diagnosing the electric vehicle based upon the monitored current and the monitored voltage.
3 more elements
An apparatus for testing an electric vehicle, comprising:
- a databus connector configured to connect to a databus of the electric vehicle;
- a microprocessor configured to:
- retrieve voltage information from the databus of the electric vehicle provided by a voltage sensor coupled to a system of the electric vehicle;
- retrieve current information from the databus of the electric vehicle provided by a voltage sensor coupled to the system of the electric vehicle;
- and
- diagnose the operation of the vehicle based upon the retrieved current information and the retrieved voltage information.
