Commission Delegated Regulation (EU) No 134/2014Show full title

2.1. Before starting the SHED test procedure, the test vehicles shall be preconditioned as follows:

2.1.1.

OVC vehicles.

2.1.1.1.

As regards OVC vehicles without an operating mode switch, the procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving (on the test track, on a chassis dynamometer, etc.) in any of the following conditions:

(a)

at a steady speed of 50 km/h until the fuel-consuming engine of the HEV starts up;

(b)

if a vehicle cannot reach a steady speed of 50 km/h without the fuel-consuming engine starting up, the speed shall be reduced until it can run at a lower steady speed at which the fuel-consuming engine does not start up for a defined time or distance (to be determined by the technical service and the manufacturer);

(c)

in accordance with the manufacturer’s recommendation.

The fuel-consuming engine shall be stopped within ten seconds of being automatically started.

2.1.1.2.

As regards OVC vehicles with an operating mode switch, the procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving with the switch in pure electric position (on the test track, on a chassis dynamometer, etc.) at a steady speed of 70 percent ± 5 percent from the maximum thirty minutes speed of the vehicle. By means of derogation if the manufacturer can prove to the technical service to the satisfaction of the approval authority that the vehicle is physically not capable of achieving the thirty minutes speed the maximum fifteen minute speed may be used instead.

Stopping the discharge occurs in any of the following conditions:

(a)

when the vehicle is not able to run at 65 percent of the maximum thirty minutes speed;

(b)

when the standard on-board instrumentation gives the driver an indication to stop the vehicle;

(c)

after 100 km.

If the vehicle is not equipped with a pure electric mode, the electrical energy/power storage device discharge shall be conducted with the vehicle driving (on the test track, on a chassis dynamometer, etc.) under any of the following conditions:

(a)

at a steady speed of 50 km/h until the fuel-consuming engine of the HEV starts up;

(b)

if a vehicle cannot reach a steady speed of 50 km/h without the fuel-consuming engine starting up, the speed shall be reduced until it can run at a lower steady speed at which the fuel-consuming engine does not start up for a defined time or distance (to be determined by the technical service and the manufacturer);

(c)

in accordance with the manufacturer’s recommendation.

The engine shall be stopped within ten seconds of being automatically started. By means of derogation if the manufacturer can prove to the technical service to the satisfaction of the approval authority that the vehicle is physically not capable of achieving the thirty minutes speed the maximum fifteen minute speed may be used instead.

2.1.2.

NOVC vehicles.

2.1.2.1.

As regards NOVC vehicles without an operating mode switch, the procedure shall start with a preconditioning of at least two consecutive complete, applicable test type I driving cycles without soak.

2.1.2.2.

As regards NOVC vehicles with an operating mode switch, the procedure shall start with a preconditioning of at least two consecutive complete, applicable driving cycles without soak, with the vehicle running in hybrid mode. If several hybrid modes are available, the test shall be carried out in the mode which is automatically set after the ignition key is turned (normal mode). On the basis of information provided by the manufacturer, the technical service shall ensure that the limit values are complied with in all hybrid modes.

2.1.3.

The preconditioning drive shall be carried out according to the type I test cycle in Appendix 6 to Annex II:

2.1.3.1.

for OVC vehicles this shall be carried out under the same conditions as specified by Condition B of the type I test in Appendix 11 to Annex II.

2.1.3.2.

for NOVC vehicles this shall be carried out under the same conditions as in the type I test.
