  "textContent": "Methods, systems, and vehicles are provided for determining a stator resistance value of an electric motor. The systems may include the electric motor including a stator and a rotor; a sensor system including configured to generate sensor data indicative of sensed operating conditions of the electric motor including a current magnitude, a current angle, a motor speed, a temperature of the stator, and a temperature of the rotor; and a controller operably coupled with the sensor system and the electric motor. The controller is configured to: determine an initial stator resistance value based on a stator reference temperature and either estimated data sensor data received from the sensor system; determine a stator temperature coefficient based on the sensor data and a stator nonlinear resistance ratio curve; and determine the stator resistance value based on the initial stator resistance value and the stator temperature coefficient.",
