79 REESS test procedures Over-discharge protection China Discharging At the beginning of the test, all relevant main contactors shall be closed. 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.

80 REESS test procedures Over-temperature protection China Over-temperature protection test Purpose The purpose of this test is to verify the performance of the protection measures of the REESS against internal overheating during operation even under the failure of the cooling function if applicable. In the case that no specific protection measures are necessary to prevent the REESS from reaching an unsafe state due to internal over-temperature, this safe operation must be demonstrated. OICA A Over-temperature protection test A Purpose The purpose of this test is to verify the performance of the protection measures of the REESS against internal overheating during operation even under the failure of the cooling function if applicable. In the case that no specific protection measures are necessary to prevent the REESS from reaching an unsafe state due to internal over-temperature, this safe operation must be demonstrated. R100 ANNEX 8I OVER-TEMPERATURE PROTECTION 1. Purpose The purpose of this test is to verify the performance of the protection measures of the REESS against internal overheating during the operation, even under the failure of the cooling function if applicable. In the case that no specific protection measures are necessary to prevent the REESS from reaching an unsafe state due to internal over-temperature, this safe operation must be demonstrated. All same
