IEC62619于2022年5月24日正式发布了:
IEC 62619-2022 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications,该版标准由IEC委员会21/21A归口起草和准备,该第二版本(2022版)将替代和取消第一版(2017版)的标准,相比以前版本该第二版本标准主要包含了以下重大的技术变更:
IEC62619-a)针对活动/运动部件提出新的要求;
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.
IEC62619-b)新增针对危险带电部件的要求;
Hazardous live parts of the battery system shall be protected to avoid the risk of electric shocks, including during installation.
IEC62619-c)新增电池组系统设计的要求;
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.
IEC62619-d)新增系统锁定功能要求;
当电池组系统中的一个或多个电芯在运行过程中偏离运行区域时,电池组系统应具有停止操作的不可复位功能,此功能不允许用户重置或自动重置。
在检查电池组系统的状态符合电池组系统制造商手册后,电池系统的功能可以复位。
根据其应用,电池组系统可以允许其最终放电一次,例如提供紧急功能。在这种情况下,在电芯不引起危险反应的范围内,电芯限值(例如放电电压下限或温度上限)可允许偏离一次。因此,电芯制造商应提供第二套限值,该限值应使在电池组系统中的电芯可以接受一次放电而不发生危险反应。在最后一次放电后,电芯不得再被充电。
IEC62619-e)新增EMC要求;
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.
