The available cooling and/or heating power on the testbench shall be determined based on the following procedures and recorded together with the actual component test data:
(1)
For liquid conditioning from the massflow of the conditioning fluid and the temperature difference over the heat exchanger on the side of the capacitor UUT.
(2)
For electric conditioning from the voltage and current. The component manufacturer may modify the electric connection of this conditioning unit for the certification of the capacitor UUT to enable a measurement of the capacitor UUT characteristics without considering the electric power required for conditioning (e.g. if the conditioning is directly implemented and connected within the capacitor UUT). Notwithstanding these provisions, the required electric cooling and/or heating power externally provided to the capacitor UUT by a conditioning unit shall be recorded.
(3)
For other types of conditioning based on good engineering judgement and discussion with the type approval authority.
6.2 Test conditions
(a)
The capacitor UUT shall be placed in a temperature controlled test cell. The ambient temperature shall be conditioned at 25 ±10 °C;
(b)
The voltage shall be measured at the terminals of the capacitor UUT.
(c)
The thermal conditioning system of the capacitor UUT and the corresponding thermal conditioning loop at the test bench equipment shall be fully operational in accordance with the respective controls.
(d)
The control unit shall enable the test bench equipment to perform the requested test procedure within the capacitor UUT operational limits. If necessary, the control unit program shall be adapted by the capacitor UUT component manufacturer for the requested test procedure.
6.3 Capacitor UUT characteristics test
(a)
After fully charging and then fully discharging the capacitor UUT to its lowest operating voltage in accordance with the charging method specified by the component manufacturer, it shall be soaked for at least 2 hours, but no more than 6 hours.
(b)
The capacitor UUT temperature at the start of the test shall be 25 ± 2 °C. However, 45 ± 2 °C may be selected by reporting to the type approval or certification authority that this temperature level is more representative for the conditions of the typical application.
(c)
After the soak time, a complete charge and discharge cycle in accordance with Figure 2 with a constant current I test shall be performed. I test shall be the maximum allowed continuous current for the capacitor UUT as specified by the component manufacturer.
(d)
After a waiting period of at least 30 seconds (t 0 to t 1 ), the capacitor UUT shall be charged with a constant current I test until the maximum operating voltage V
max is reached. Then, the charging shall be stopped and the capacitor UUT shall be soaked for 30 seconds (t 2 to t 3 ) so that the voltage can settle to its final value V
b before the discharging is started. After that the capacitor UUT shall be discharged with a constant current I test until the lowest operating voltage V
min is reached. Afterwards (from t 4 onwards) there shall be another waiting period of at least 30 seconds for the voltage to settle to its final value V c .
(e)
The current and voltage over time, respectively I meas and V meas , shall be recorded at a sampling frequency of at least 10 Hz.
(f)
The following characteristic values shall be determined from the measurement (illustrated in Figure 2):
V
a is the no-load voltage right before start of the charge pulse
V
b is the no-load voltage right before start of the discharge pulse
V
c is the no-load voltage after the end of the discharge pulse
ΔV ( t
1 ), ΔV ( t
3 ) are the voltage changes directly after applying the constant charging or discharging current I
test at the time of t
1 and t
3 , respectively. These voltage changes shall be determined by applying a linear approximation to the voltage characteristics as defined in detail A of Figure 2 by usage of the least squares method. Data sampling for the straight line approximation shall start once the change in the gradient calculated from two adjacent data points is smaller than 0.5 % when running in the direction of increasing time signal.
Figure 2
Example of voltage curve for the capacitor UUT measurement
ΔV ( t
1 ) is the absolute difference of voltages between V
a and the intercept value of the straight-line approximation at the time of t
1 .
ΔV ( t
3 ) is the absolute difference of voltages between V
b and the intercept value of the straight-line approximation at the time of t
3 .
ΔV ( t
2 ) is the absolute difference of voltages between V
max and V
b .
ΔV ( t
4 ) is the absolute difference of voltages between V
min and V
c .
6.4. Post-processing of measurement data of the capacitor UUT
6.4.1 Calculation of internal resistance and capacitance
The measurement data obtained in accordance with point 6.3 shall be used to calculate the internal resistance (R) and capacitance (C) values in accordance with the following equations:
(a)
The capacitance for charging and discharging shall be calculated as follows:
For charging:

Standard values for electric machine system
The following steps shall be performed to generate the input data for the electric machine system based on standard values:
—
Step 1: UN Regulation No. 85 shall be applied for this Appendix unless stated otherwise.
—
Step 2: The maximum torque values as a function of the rotational speed shall be determined from the data generated in accordance with paragraph 5.3.1.4 of UN Regulation No. 85. The data shall be extended in accordance with point 4.3.2 of this Annex.
—
Step 3: The minimum torque values as a function of the rotational speed shall be determined by multiplying the torque values from Step 2 above by minus one.
—
Step 4: The maximum 30 minutes continuous torque and the corresponding rotational speed shall be determined from the data generated in accordance with paragraph 5.3.2.3 of UN Regulation No. 85 as average values over the 30 minutes period. In case no value for the maximum 30 minutes continuous torque in accordance with Regulation No. 85 can be determined or the value determined is 0 Nm, the applicable input data shall be set to 0 Nm and the corresponding rotational speed shall be set to the rated speed determined from the data generated in accordance with Step 2 above.
—
Step 5: The overload characteristics shall be determined from the data generated in accordance with Step 2 above. The overload torque and the corresponding rotational speed shall be calculated as average values over the speed range where the power is equal or greater than 90 % of the maximum power. The overload duration t 0_maxP shall be defined by the whole duration of the test run performed in accordance with Step 2 above multiplied by a factor of 0,25.

‘Appendix 13
Family concept
1. Electric machine systems and IEPCs
1.1. General
A family of electric machine systems or IEPCs is characterised by design and performance parameters. These shall be common to all members within the family. The component manufacturer may decide which electric machine systems or IEPCs belong to a family, as long as the membership criteria listed in this Appendix are respected. The related family shall be approved by the Approval Authority. The component manufacturer shall provide to the Approval Authority the appropriate information relating to the members of the family.
1.2. Special cases
In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that electric machine systems or IEPCs with similar characteristics are included within the same family. These cases shall be identified by the component manufacturer and notified to the Approval Authority. It shall then be taken into account as a criterion for creating a new family of electric machine systems or IEPCs.
In the case of devices or features, which are not listed in paragraph 1.4 and which have a strong influence on the level of performance and/or the electric power consumption, the respective devices or features shall be identified by the component manufacturer on the basis of good engineering practice, and shall be notified to the Approval Authority. It shall then be taken into account as a criterion for creating a new family of electric machine systems or IEPCs.
1.3. Family concept
The family concept defines criteria and parameters enabling the component manufacturer to group electric machine systems or IEPCs into families with similar or equal data relevant for CO 2 -emissions or energy consumption.
1.4. Special provisions regarding representativeness
The Approval Authority may conclude that the performance parameters and the electric power consumption of the family of electric machine systems or IEPCs can best be characterised by additional testing. In this case, the component manufacturer shall submit the appropriate information to determine the electric machine system or IEPC within the family likely to best represent the family. The Approval Authority may based on this information also conclude that it is required for the component manufacturer to create a new family of electric machine systems or IEPCs consisting of less members in order to be more representative.
If members within a family incorporate other features which may be considered to affect the performance parameters and/or the electric power consumption, these features shall also be identified and taken into account in the selection of the parent.
1.5. Parameters defining a family of electric machine systems or IEPCs
In addition to the parameters listed below, the component manufacturer may introduce additional criteria allowing the definition of families of more restricted size. These parameters are not necessarily parameters that have an influence on the level of performance and/or the electric power consumption.
1.5.1.
The following criteria shall in principal be the same to all members within a family of electric machine systems or IEPCs:
(a)
Electric Machine: Rotor, Stator, Windings in dimensions, design, material, etc.
(b)
Inverter: Power Modules, Conductive bars in dimensions, design, material, etc.
(c)

(f)
Gear related parameters (only for IEPCs): in accordance with definitions set out in Annex VI.
Changes to the components as mentioned at (a) through (f) are only acceptable as long as sound engineering rationale can be provided to prove that the respective change does not negatively affect the performance parameters and/or the electric power consumption.
1.5.2.
The following criteria shall be common to all members within a family of electric machine systems or IEPCs. The application of a specific range to the parameters listed below is permitted after approval of the Approval Authority:
(a)
Output shaft interface: any changes allowed;
(b)
End shields:
For the internal design it must be checked if passive cooling elements or air flow at the inner side of the end shields are affected by changes.
For the external design screws, suspension points, flange design have no influence on performance if no passive cooling elements are removed or changed;
(c)
Bearings: Changes allowed as long as number and type of bearings remain the same;
(d)
Shaft: Changes allowed as long as active or passive cooling is not affected;
(e)
High voltage connection: Changes regarding position or type of the high voltage connection allowed;
(f)
Housing: Changes of the housing or number, type and position of screws or mounting points allowed as long as no passive cooling elements are removed or changed;
(g)
Sensor: Changes allowed, if certified performance is not changed;
(h)

(l)
Oil viscosity: for all oils that are specified for the factory fill, the kinematic viscosity at the same temperature shall be less or equal to 110 % of the kinematic viscosity of the oil used for component certification as documented in the respective information document (within the specified tolerance band for KV100);
(m)
Maximum torque curve
The torque values at each rotational speed of the maximum torque curve of the parent determined in accordance with paragraph 4.2.2.4 of this Annex shall be equal or higher than for all other members within the same family at the same rotational speed over the whole rotational speed range. Torque values of other members within the same family within a tolerance of +40 Nm or +4 %, whatever is larger, above the maximum torque of the parent at a specific rotational speed are considered as equal;
(n)
Minimum torque curve
The torque values at each rotational speed of the minimum torque curve of the parent determined in accordance with paragraph 4.2.2.4 of this Annex shall be equal or lower than for all other members within the same family at the same rotational speed over the whole rotational speed range. Torque values of other members within the same family within a tolerance of -40 Nm or -4 %, whatever is larger, below the minimum torque of the parent at a specific rotational speed are considered as equal;
(o)
Minimum number of points in the EPMC map:
All members within the same family shall have a minimum coverage of 60 % of the points (rounded up to the next whole number) of the EPMC map (i.e. where the EPMC map of the parent is applied to other members) located within the boundaries of their respective maximum and minimum torque curves determined in accordance with paragraph 4.2.2.4 of this Annex.
1.6. Choice of the parent
The parent of one family of electric machine systems or IEPCs shall be member with the highest overall maximum torque determined in accordance with paragraph 4.2.2 of this Annex.
