paragraph 3.2. above.

       4.2. The Tested-Device shall be continuously charged and discharged by the external charge/discharge equipment with a current that will increase the temperature of cells as rapidly as possible within the range of normal operation as defined by the manufacturer until the end of the test.

       Alternatively, the charge and discharge may be conducted by vehicle driving operations on chassis dynamometer where the driving operation shall be determined through consultation with the manufacturer to achieve the conditions above.

       4.3. The temperature of the chamber or oven shall be gradually increased, from 20 ± 10 °C or at higher temperature if requested by the manufacturer, until it reaches the temperature determined in accordance with paragraph 4.3.1. or 4.3.2. below as applicable, and then maintained at a temperature that is equal to or higher than this, until the end of the test.

       4.3.1. Where the REESS is equipped with protective measures against internal overheating, the temperature shall be increased to the temperature defined by the manufacturer as being the operational temperature threshold for such protective measures, to ensure that the temperature of the Tested-Device will increase as specified in paragraph 4.2. above.

       4.3.2. Where the REESS is not equipped with any specific measures against internal over-heating, the temperature shall be increased to the maximum operational temperature specified by the manufacturer.

       4.4. The end of test: The test will end when one of the followings is observed:

           (a) The Tested-Device inhibits and/or limits the charge and/or discharge to prevent the temperature increase;

           (b) The temperature of the Tested-Device is stabilised, which means that the temperature varies by a gradient of less than 4 °C through 2 hours;

           (c) Any failure of the acceptance criteria prescribed in paragraph 6.9.2.1. of the Regulation.

       5. Installation for test conducted using a complete vehicle.

       5.1. Based on information from the manufacturer, for a REESS fitted with a cooling function the cooling system shall be disabled or in a state of significantly reduced operation (for a REESS that will not operate if the cooling system is disabled) for the test.

       5.2. The temperature of the REESS shall be continuously measured inside the casing in the proximity of the cells during the test to monitor the changes of temperature using on-board sensors and compatible tools according to manufacturer provided information for reading the signals.

       5.3. The vehicle shall be placed in a climate control chamber set to a temperature between 40 °C to 45 °C for at least 6 hours.

       6. Test procedures for test conducted using a complete vehicle.

       6.1. The vehicle shall be continuously charged and discharged in a manner that will increases the temperature of REESS cells as rapidly as possible within the range
