Abstract
A method for operating a controller includes receiving a first accumulated thermal value of an electrical machine and an associated first time stamp from a memory, initializing a processor of the controller with the first accumulated thermal value and the associated first time stamp, determining whether a second time stamp has been received, calculating a difference between the second time stamp and the first time stamp responsive to determining that the second time stamp has been received, calculating a second accumulated thermal value as a function of the first accumulated thermal value, the first time stamp, and the second time stamp, and updating the first accumulated thermal value with the second accumulated thermal value.
