Abstract
A battery management controller includes input channels to receive a voltage signal from a battery and output channels to provide diagnostic signals to an operator. The controller is programmed to output a diagnostic signal predictive of a thermal condition in response to the voltage decreasing at a rate greater than a predetermined rate that signals that the voltage is decreasing toward a local minimum that precedes an increase in the voltage indicative of a battery temperature increase rate becoming greater than a threshold. The diagnostic signal may be used to alert the operator of the condition. The controller may be further programmed to issue commands to mitigate the thermal condition based on the diagnostic signal.
