Abstract
The invention relates to a method for locating a cause of the premature discharge of a battery in a vehicle. To simplify locating a cause of the premature discharge of a battery in a vehicle, it is proposed to monitor the current drawn from the battery via an electrical system of the vehicle in the ignition-off-state. Data collected as part of the monitoring can then be examined either alone or in conjunction with additional, in particular, vehicle-specific and/or global data, for information relevant to isolating and/or determining the cause.
Claims18
A method for locating a cause of a premature discharge of a battery in a vehicle, the method comprising:
- monitoring, in an ignition-off state, a current drawn from the battery via an electrical system of the vehicle;
- examining data collected during the monitoring alone or in conjunction with vehicle-specific and/or global data for information relevant to isolating and/or determining the cause of the premature discharge;
- modifying a sampling rate of the data associated with the cause of the premature discharge;
- identifying the cause of the premature discharge as a software problem;
- and
- eliminating the cause of the premature discharge by installing software previously transmitted to the vehicle from an outside source over a wired or wireless connection.
