Measurement Uncertainty, Accuracy and Safety in Electric Powertrain Testing

A measurement has no value unless you know the Measurement Uncertainty (MU) of the result. However, MU for fundamental Power and Efficiency is a complicated process requiring hundreds or thousands of calculations since it must take into account the power analyzer-recorder, current sensors, burden resistors, torque sensors and speed sensors used for the measurement. In addition to Measurement Uncertainty, there are also many other challenges to making safe and accurate electric powertrain measurements including: Electro-Magnetic Interference (EMI) Higher voltages and slew rates (industry trends) Cable management, shielding and connections Sensor accuracy, connectivity, grounding and shielding Mechanical noise (torque ripple) Electrical noise (harmonics) Amplifier and signal accuracy, noise and shielding Learn how to overcome these challenges, improve accuracy, mitigate EMI, map torque ripple, measure harmonics, achieve uncompromised safety and rapidly calculate and map Measurement Uncertainty (MU) for every efficiency setpoint in your Electric Powertrain Measurement using a future proof testing solution.
