3 Test Preparation
3.1 Selection of measuring apparatus
3.1.1 Accuracy of apparatus
Magnetic electric instrument or other instruments, including digital instruments, which are able to
read the effective values, may be adopted for measuring the effective values of voltage and
current. During the test, the accuracy of adopted electric measuring apparatus and instruments
shall not be less than Grade 0.5 (except for the tramegger). And the accuracy of DC shunt shall
not be less than Grade 0.2. The accuracy of digital rotating speed gauge shall not be less than
0.1% ± 1 digits. The accuracy of torque measuring instrument and dynamometer shall not be less
than 1% (when directly measuring the efficiency, it shall not be less than 0.5%). And the error of
thermometer shall be within ± 1°C.
When selecting the instrument, the measured value shall be within the range of 20%~95% of the
instrument range.
3.1.2 Measuring requirements
a) Within the permissible measurement range of the amperemeter, a shunt shall not be
adopted as much as possible. When measuring current with a shunt, the resistance of
measuring wire shall be selected according to the selecte voltmeter.
b) During the test, each instrument shall be read simultaneously.
3.1.3 Measurement of input power of the controller
The measured value of input power of electrical machine controller is the PRODUCT of the
measured values of input voltage AND the current of the electrical machine controller. The input
voltage shall be measured at the input terminal of the controller, and the input current shall be
measured at the input connection of the controller.

The DC power supply served shall meet the characteristics of voltage and current that of the
vehicle battery. And the supply output impedance shall be equal to the specified battery
impedance as much as possible.
3.3 Wiring
The wiring during the test shall be similar to the wiring in vehicles. Attention shall be paid to that
the impedance of the external circuit of supply controller shall be equal to the impedance of
wiring in vehicles as much as possible, supposing that the wiring inevitably differs from the one
in vehicles.
3.4 Cooling device
For cooling conditions of electrical machines and controllers, specific application conditions in
vehicles shall be simulated. And the type of cooling device for electrical machines and controllers
shall be recorded into the parameter testing reports of the electrical machine power of electric
vehicles.
Feeding efficiency shall be calculated according to Formula (12).

Where,
W2 - energy input to power supply during feeding test.
b) Test by using an inertia wheel device
Measure the angular speed ω1 of inertia wheel before the feeding test, and the angular
speed ω2 after the feeding test. Meanwhile measure the voltage at both ends of the power
supply, and the current and duration of input power supply during feeding.
Energy shall be calculated according to Formula (13).
