Temperature based resistive braking capacity

A method of controlling an electric drive machine, the method comprising:

• determining, by one or more processors, a temperature of a resistor element of a resistor grid electrically coupled to a motor of an electric drive machine;
• determining, by the one or more processors, a resistive braking capacity of the resistor grid within a power capacity differential, according to the determined temperature of the resistor element;
• and
• rendering, by the one or more processors, a graphical representation of the resistive braking capacity of the resistor grid relative to the power capacity differential on a display of the electric drive machine.

An electric drive machine comprising:

• a resistor grid comprising a plurality of resistor elements, the resistor grid electrically coupled to a motor of the electric drive machine;
• a temperature sensor arranged to measure a temperature of at least one of the plurality of resistor elements;
• a control circuit comprising one or more processors and memory structured to store instructions that, when executed by the one or more processors, cause the control circuit to:
• determine a temperature of the least one resistor element, according to measurements from the temperature sensor;
• and
• determine a resistive braking capacity of the resistor grid within a power capacity differential, according to the determined temperature of the resistor element;
• and
• a display configured to render a graphical representation of the resistive braking capacity of the resistor grid relative to the power capacity differential.
