REESS test procedures

Annex 8 – Appendix 1

Procedure for conducting a standard cycle

       A standard cycle will start with a standard discharge followed by a standard charge.

       Standard discharge:

                     Discharge rate:  The discharge procedure including termination criteria shall be defined by the manufacturer. If not specified, then it shall be a discharge with 1C current.

       Discharge limit (end voltage): Specified by the manufacturer

       Rest period after discharge:  Minimum 30 min

                     Standard charge:  The charge procedure including termination criteria shall be defined by the manufacturer. If not specified, then it shall be a charge with C/3 current.

Annex 8A

Vibration test

       1.  Purpose

        The purpose of this test is to verify the safety performance of the REESS under a vibration environment which the REESS will likely experience during the normal operation of the vehicle.

       2.  Installations

       2.1. This test shall be conducted either with the complete REESS or with a 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 under the same conditions. If the electronic management unit for the REESS is not integrated in the casing enclosing the cells, then the electronic management unit may be omitted from installation on the tested-device if so requested by the manufacturer.

       2.2. The tested-device shall be firmly secured to the platform of the vibration machine in such a manner as to ensure that the vibrations are directly transmitted to the tested-device.

       3. Procedures

       3.1. General test conditions

       The following conditions shall apply to the tested-device:

       (a) The test shall be conducted at an ambient temperature of 20 ± 10 °C;

           (b) At the beginning of the test, the
