AS IEC 62619:2017 pdf free.Secondary cells and batteries containing alkaline or other non-acid electrolytes-Safety requirements for secondary lithium cells and batteries, for use in industrial applications.
8.2.3 Overcharge control of current (battery system)
a) Requirement
In case the input current to the cells and batteries exceeds the maximum charging current of the cells, the BMS shall interrupt the charging to protect the battery system from hazards related to charging currents above the cells specified maximum charging current.
NOTE If the maximum ability of charging current of the system is lower than the maximum charging Current for the battery, thés test can be waived
b) Test
The test shall be carried out in an ambient temperature of 25 C ± 5 ‘C and under normal operating conditions with the cooling system (if any) operating (main contactors closed with the battery system being controlled by the BMS). Each test battery system shall be discharged at a constant current of 0,2 i A. to a final voltage specified by the manufacturer. Sample batteries shall then be charged at a current exceeding the maximum charging current by 20 %. Data acquisition/monitoring shall be continued for 1 h after charging is stopped. All functions of the battery system shall be fully operational as designed during the test.
C) Acceptance criteria
The BMS shall detect the overcharging current and shall control the charging below the maximum charging current in order to protect the battery system against further related severe effects
No fire, no explosion.
8.2.4 Overheating control (battery system)
a) Requirement
The BMS shall terminate charging when the temperature of the cells and/or battery exceeds the upper limit that is specified by the cell manufacturer.
b) Test
The test shall be carried out in an initial ambient temperature of 25 C ± 5 C and under normal operating conditions (main contactors are closed with battery system being controlled by the BMS) with the exception that the cooling system, if provided, shall be disconnected. Each test battery system shall be discharged at a constant current of 0,2 I A, to a final voltage specified by the manufacturer. Sample batteries shall then be charged at the recommended current to a 50 % state of charge. The temperature of the battery system shall be increased to 5 C above the maximum operating temperature. The charging is continued at the elevated temperature until the BMS terminates the charging. Data acquisition/monitoring shall be continued for one hour after the sequence is stopped (e.g. the BMS has terminated charging).
c) Acceptance criteria
The BMS shall detect the overheat temperature and shall terminate charging in order to protect the battery system against further related severe effects. All functions of the battery system shall be fully operational as designed during the test.
No fire, no explosion.
9 Information for safety
The use, and particularly abuse, of secondary lithium cells and batteries may result in the creation of hazards and may cause harm. The cell manufacturer shall provide information about current, voltage and temperature limits of their products. The battery system manufacturer shall provide information regarding how to mitigate hazards to equipment manufacturers and, in the case of direct sales, to end-users. It is the equipment manufacturer’s responsibility to inform end-users of the potential hazards arising from the use of equipment containing secondary lithium cells and batteries.
