shall be made of a refractory material, as prescribed in Annex 8E - Appendix 1. There shall
shall be 2cm to 4cm smaller than the interior dimensions of the pan so that a gap of 1cm to
2cm exists between the frame and the wall of the pan to allow ventilation. Before the test the
screen shall be at least at the ambient temperature. The firebricks may be wetted in order to
guarantee repeatable test conditions.
the wind velocity at pan level shall not exceed 2.5km/h.
The fuel in the pan shall be ignited at a distance of at least 3m from the tested-device. After
60s pre-heating, the pan shall be placed under the tested-device. If the size of the pan is too
large to be moved without risking liquid spills etc. then the tested-device and test rig can be
moved over the pan instead.
The burning pan covered with the screen shall be moved back to the position described in
Phase A. No extinguishing of the tested-device shall be done. After removal of the pan the
tested-device shall be observed until such time as the surface temperature of the
tested-device has decreased to ambient temperature or has been decreasing for a minimum
The test shall be conducted at a ambient temperature of 20 ± 10°C or at higher
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
closed to represent the active driving possible mode as well as the mode to enable external
charging. If this cannot be completed in a single test, then two or more tests shall be
The positive and negative terminals of the tested-device shall be connected to each other to
produce a short circuit. The connection used for this purpose shall have a resistance not
exceeding 5mΩ.
The short circuit condition shall be continued until the operation of the REESS´s protection
function to interrupt or limit the short circuit current is confirmed, or for at least one hour after
the temperature measured on the casing of the tested-device has stabilised, such that the
temperature gradient varies by a less than 4°C through 1 hour.
This test shall be conducted, under standard operating conditions, either with the complete
REESS (this maybe a complete vehicle) or with related REESS subsystem(s), including the
cells and their electrical connections. If the manufacturer chooses to test with related
subsystem(s), the manufacturer shall demonstrate that the test result can reasonably
represent the performance of the complete REESS with respect to its safety performance
The test shall be conducted at an ambient temperature of 20 ± 10°C or at higher
The charging shall be continued until the tested-device (automatically) interrupts or limits the
charging. Where an automatic interrupt function fails to operate, or if there is no such
The purpose of this test is to verify the performance of the over-discharge protection. This
functionality, if implemented, shall interrupt or limit the discharge current to prevent the
REESS from any severe events caused by a too low SOC as specified by the manufacturer.
A discharge shall be performed with at least 1/3 C rate but shall not exceed the maximum
current within the normal operating range as specified by the manufacturer.
The discharging shall be continued until the tested-device (automatically) interrupts or limits
the discharging. 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 to 25%
of its nominal voltage level.
3.3. Standard Charge and Observation Period
Directly after termination of the discharging the tested-device shall be charged with a
standard charge as specified in Annex 8, Appendix 1 if not inhibited by the tested-device.

and then maintained at a temperature that is equal to or higher than this, until the end of the
3.3.1. 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 insure that the
temperature of the tested-device will increase as specified in Paragraph 3.2. above.
3.3.2. 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
3.4. The End of Test:
The test will end when one of the followings is observed:
The tested-device inhibits and/or limits the charge and/or discharge to prevent the
The temperature of the tested-device is stabilised, which means that the temperature
varies by a gradient of less than 4°C through 2h;
Any failure of the acceptance criteria prescribed in Paragraph 6.9.2.1. of the
