audio-visual equipment, etc., that can be switched on under the conditions given in paragraph 3.2.2.(a). The operation shall be terminated when the vehicle's over-discharge protection control terminates REESS discharge current or the temperature of the REESS is stabilized such that the temperature varies by a gradient of less than 4 °C through 2 hours. Where an over-discharge protection control fails to operate, or if there is no such control, then the discharging shall be continued until the REESS is discharged to 25 per cent of its nominal voltage level;

           (c) Immediately after the termination of discharging, one standard charge followed by a standard discharge as described in Annex 9, Appendix 1 shall be conducted if it is not prohibited by the vehicle.

       3.2.3. Discharge of REESS using discharge resistor (vehicle-based test).

       This procedure is applicable to vehicles for which the manufacturer provides information to connect a breakout harness to a location just outside the REESS that permits discharging the REESS:

           (a) Connect the breakout harness to the vehicle as specified by the manufacturer. Place the vehicle in active driving possible mode;

           (b) A discharge resistor is connected to the breakout harness and the REESS shall be discharged at a discharge rate under normal operating conditions in accordance with manufacturer provided information. A resistor with discharge power of 1 kW may be used;

           (c) The test shall be terminated when the vehicle's over-discharge protection control terminates REESS discharge current or the temperature of the REESS is stabilized such that the temperature varies by a gradient of less than 4 °C through 2 hours. Where an automatic discharge interrupt function fails to operate, or if there is no such function, then the discharging shall be continued until the REESS is discharged to 25 per cent of its nominal voltage level;

           (d) Immediately after the termination of discharging, one standard charge followed by a standard discharge as described in Annex 9, Appendix 1 shall be conducted if it is not prohibited by the vehicle.

       3.2.4. Discharge by external equipment (component-based test).

       This procedure is applicable to component-based test:

           (a) All relevant main contactors shall be closed. The external charge-discharge shall be connected to the main terminals of the Tested-Device;

           (b) A discharge shall be performed with a stable current within the normal operating range as specified by the manufacturer;

           (c) The discharging shall be continued until the Tested-Device (automatically) terminates REESS discharge current or the temperature of the Tested-Device is stabilized such that the temperature varies by a gradient of less than 4 °C through 2 hours. Where an automatic interrupt function fails to operate, or if there is no such function, then the discharging shall be continued until the Tested-Device is discharged
