Conductive grease formulations and grounding solutions for electric drive unit

A testing platform for testing conductivity of grease in bearings, the testing platform comprising:

• pillars extending from a platform;
• bearings mounted to an electrically isolated structure between the pillars;
• shafts supported by the pillars, the shafts mechanically coupling the bearings to motors;
• and
• electrical terminals configured to measure electrical resistance between the bearings as the bearings are rotated by the motors.

A testing platform for testing grounding effectiveness of grease and grounding solutions in a drivetrain, the testing platform comprising:

• a pin mount positioned in a rotor shaft of the drivetrain;
• a spring mount bearing coupled to a spring of a bearing spring of the drivetrain;
• a rotary electrical contact mount inserted into the spring mount bearing;
• a rotary electrical contact inserted into the rotary electrical contact mount;
• a pin mounted to the pin mount and the rotary electrical contact;
• and
• an electrical connection to the rotary electrical contact mount measuring electrical voltage and current on the rotor shaft via the pin and pin mount as the rotor shaft is rotated.
