Abstract

Systems and methods for monitoring a voltage pump to determine the status of a battery connected to the voltage pump are provided. The operation of the voltage pump is monitored during at least one monitoring period which corresponds to a period of relatively heavy consistent load. The operation of the voltage pump can be monitored by sampling a control signal that corresponds to the operation of the voltage pump.
