Abstract

The present disclosure relates to systems, methods and computer program products for thermal management of a brake chopper resistor. The system comprises a resistor housing portion configured to receive a cooling fluid in a cooling fluid flow path; a brake chopper resistor in the resistor housing portion; a plurality of temperature sensors in thermal communication with different respective parts of the resistor cooling flow path through the resistor housing portion and configured to measure a first temperature at a first location in the cooling fluid flow path of the brake chopper resistor and to measure a second temperature at a second location in the cooling fluid flow path of the brake chopper resistor; and control logic, configured to compare the first temperature and/or the second temperature to a threshold value or to compare the first temperature with the second temperature, and to make a determination of whether to allow activation of the brake chopper resistor in response to the comparison with the threshold value.
