IEC 62619: 2017 Secondary Batteries Containing Alkaline or Other Non acid Electrolytes - Safety Requirements for Secondary Lithium Batteries for Industrial Applications This standard was first issued on February 13, 2017 and is a safety standard for batteries used in industrial equipment in the IEC standard system.
The new standard IEC 62619: 2022 has been issued on May 24, 2022. Compared with the 2017 version, the detailed changes of the new version are shown in the table below. For the changes of the new version, the customer needs to pay special attention to the following changes, which need to be considered in the early design and development process:
● The requirement of system lock is added: it is equivalent to adding a redundant protection requirement, which is critical to the safety of the battery system and can avoid user abuse when the battery system fails.
● The impact test method of bag shaped electric core is the same as that of prismatic electric core, that is, the test is conducted in both side and wide directions. However, according to previous experience, the failure rate of side impact of soft package is more than 30%.
● EMC requirements have been added. Although there are no specific testing requirements in the standard, the terminal will put forward requirements in consideration of the EMC testing that may affect the terminal products. In terms of product design and the use of electronic parts, full consideration should be given to whether EMC requirements are met.
IEC62619-a) puts forward new requirements for moving/moving parts
Moving parts that have potential to cause human injuries shall be applied using an appropriate design and necessary measures to reduce the risk of injuries, including those injuries that may be incurred during installation, while cells or battery systems are being incorporated into equipment.
Proper design and necessary measures shall be taken to apply the moving parts that may cause personal injury to reduce the risk of injury, including the possible injury during installation when the battery or battery pack system is installed in the equipment.
IEC62619-b) new requirements for hazardous live parts; Hazardous live parts of the battery system shall be protected to avoid the risk of electric shocks, including during installation.
Hazardous live parts of the battery system shall be protected against the risk of electric shock, including during installation.
IEC62619-c) Requirements for new battery pack system design;
5.6.2 Battery system design The voltage control function of the battery system design shall ensure that the voltage of each cell or cell block shall not exceed the upper limit charging voltage specified by the manufacturer of the cells, except in the case where the end-devices provide the voltage control function. In such a case, the end-devices are considered as part of the battery system. Refer to Note 2 and Note 3 in 3.1 2.
5.6.2 Battery system design The voltage control function of the battery system design shall ensure that the voltage of each battery or battery block does not exceed the upper charging voltage specified by the battery manufacturer, unless the terminal equipment provides the voltage control function. In this case, the terminal device is considered as part of the battery system. Refer to Notes 2 and 3 in 3.12.
IEC62619-d) New system locking function requirements;
When one or more cells in the battery pack system deviate from the operating area during operation, the battery pack system shall have a non reset function to stop operation, which does not allow users to reset or automatically reset.
After checking that the status of the battery system conforms to the manufacturer's manual of the battery system, the functions of the battery system can be reset.
Depending on its application, the battery pack system can allow it to discharge once finally, for example to provide emergency functions. In this case, the limit value of the electric core (such as the lower limit of the discharge voltage or the upper limit of the temperature) can be allowed to deviate once within the range that the electric core does not cause dangerous reactions. Therefore, the cell manufacturer shall provide a second set of limit values, which shall enable the cell in the battery pack system to accept a discharge without dangerous reaction. After the last discharge, the cell shall not be charged again.
IEC62619-e) New EMC requirements
The battery system shall fulfil EMC requirements of the end-device application such as stationary, traction, railway, etc. or the specific requirements agreed between the end-device manufacturer and the battery system manufacturer. The EMC test may be conducted on the end-device, if feasible.
The battery system shall meet the EMC requirements of terminal equipment application, such as fixation, traction, railway, etc. Or specific requirements agreed between the terminal equipment manufacturer and the battery system manufacturer. If feasible, the EMC test can be conducted on the terminal equipment.
IEC62619-f) added a procedure based on laser for thermal runaway propagation.
