           (c) For vehicle-based test of vehicles with on-board energy conversion systems (e.g. internal combustion engine, fuel cell, etc.), fill the fuel to allow the operation of such energy conversion systems;

           (d) At the beginning of the test, all protection devices which would affect the function of the Tested-Device and which are relevant to the outcome of the test shall be operational. All relevant main contactors for charging shall be closed.

       3.2. Charging

       The procedure for charging the REESS for vehicle-based test shall be in accordance with paragraphs 3.2.1. and 3.2.2. and shall be selected as appropriate for the relevant mode of vehicle operation and the functionality of the protection system. Alternatively, the procedure for charging the REESS for vehicle-based test shall be in accordance with paragraph 3.2.3. For component-based test, the charging procedure shall be in accordance with paragraph 3.2.4.

       3.2.1. Charge by vehicle operation.

       This procedure is applicable to the vehicle-based tests in active driving possible mode:

           (a) For vehicles that can be charged by on-board energy sources (e.g. energy recuperation, on-board energy conversion systems), the vehicle shall be driven on a chassis dynamometer. The vehicle operation on a chassis dynamometer (e.g. simulation of continuous down-hill driving) that will deliver as high charging current as reasonably achievable shall be determined, if necessary, through consultation with the manufacturer.

           (b) The REESS shall be charged by the vehicle operation on a chassis dynamometer in accordance with paragraph 3.2.1.(a). The vehicle operation on the chassis dynamometer shall be terminated when the vehicle's overcharge protection controls terminates the REESS charge current or the temperature of the REESS is stabilized such that the temperature varies by a gradient of less than 2 °C through 1 hour. Where an automatic interrupt function vehicle's overcharge protection control fails to operate, or if there is no such control function, the charging shall be continued until the REESS temperature reaches 10 °C above its maximum operating temperature specified by the manufacturer.

           (c) Immediately after the termination of charging, one standard cycle as described in Annex 9, Appendix 1 shall be conducted, if it is not prohibited by the vehicle, with vehicle operation on a chassis dynamometer.

       3.2.2. Charge by external electricity supply (vehicle-based test).

       This procedure is applicable to vehicle-based test for externally chargeable vehicles:

           (a) The vehicle inlet for normal use, if it exists, shall be used for connecting the external electricity supply equipment. The charge control communication of the external electricity supply equipment shall be altered or disabled to allow the charging specified in paragraph 3.2.2.(b) below;

           (b) The REESS shall be charged by the external electricity supply equipment with the maximum charge current specified by the manufacturer. The charging shall be terminated when the
