澳大利亚公布了自愿标准草案 DR AS/NZS 5139:201X 电气装置 – 与电源转换设备一起使用电池系统的安全性。该项标准是由澳大利亚和新西兰各利益相关方联合制定,其中包括如下条款:
•所有可连接到变频器电源系统的电池系统的安装要求,涵盖所有电池类型;
•减轻与蓄电池储能系统安装相关的危害;
•根据电池危害而非化学物质类型对电池分类。
供公众评议的草案的公布符合澳大利亚标准协会于2017年2月发布的“能源储存标准路线图的建议。在路线图中,利益相关方认为需要制定安全安装电池储能系统装置标准,并作为最优先事项。家庭中电池系统的所在位置标准草案的制定过程并没有引起争议。
2017年上半年,媒体关注到标准草案将禁止家庭中使用锂离子电池。自此,产业与政府方专家与社会利益关切方共同合作,制定了本次发布的标准草案。目前,标准草案包含的条款旨在尽量减少自燃情况的出现。
考虑到与这些系统相关的火灾的危害,草案还包含了旨在排除特定电池安装在家庭住宅中情况的条款。如可达到特定的火灾相关安全标准,这些电池也可被安装在家庭住宅外部或毗邻住宅处。条款还包括了在没有可用产品标准、且处于储能系统潜在故障模式下时,如何防止灾害
发生。很显然,在形成标准草案时,各利益相关方在草案是否制定恰当、新兴科技带来的益处是否可以恰当平衡社会安全期待方面存在不同意见。鉴于在家庭中安装蓄电池的兴趣水平,公众对草案的意见特别集中在第4.5.3条和表3.1上。
该标准草案是在未来国家电力市场独立审查报告(Finkel报告)发布不到一周内发布的。该报告指出,由于消费者需求推动影响,到2035年,澳大利亚家庭中将安装超过1百万套现场电池储能系统。为何澳大利亚不直接使用国际标准?在电池储能系统方面,尚未出台相关的国际电
气装置标准。
该草案是由澳大利亚和新西兰利益相关方共同制定的,这两个国家的利益相关方遵守同样的法规及技术标准框架。使用现场电池储能系统是国际上新兴的发展领域,不同的国家在其管辖范围内制定不同的要求。该草案参考了多种国际标准,尤其是那些与系统组件相关的标准文件
保持一致。谁制定了这份文件?制定这份文件的技术委员会是EL-042 可再生能源供应系统和设备委员会。该委员会包括来自产业、政府部门、学界和其他利益相关方的干系人,其成员如附件所述。之后的流程是什么?技术委员会将认真考虑并解决这9周内公众提出的所有意见。
如果其对草案进行实质性修改,新修改后的文件将在发布后进行近一步磋商。
当所有意见得到解决后,技术委员会将进行投票,决定是否公布标准文件。所有澳大利亚标准的使用均采取自愿原则;政府可在制定规定时选择参照澳大利亚标准协会或其他方制定的标准文件。获取标准草案并通过我们的公众意见平台提供意见。所有意见须在2017年8月15日前
提交。
Consultation commences on new draft standard for On-Site Battery Systems Standards
Australia has released for consultation a draft voluntary standard, DR AS/NZS 5139:201X Electrical installations – safety of battery systems for use with power conversion equipment. The standard, prepared jointly by Australian and New Zealand stakeholders, includes provision for:
• Installation requirements for all battery systems connected to inverter energy systems, covering all battery types;
• Mitigating hazards associated with battery energy storage system installations; and
• Classifying batteries based on hazards, rather than chemistry type.
The release of the draft for public consultation aligns with the recommendations of the Roadmap for Energy Storage Standards released by Standards Australia in February 2017. In the Roadmap, stakeholders identified the need to develop a Standard for the safe installation of battery energy storage systems as a top priority. The location of battery systems in homes The development of the draft standard has not been without controversy. Earlier in 2017, concerns were raised in the media that the draft standard would seek to ban lithium-ion batteries in homes. Since then, experts from industry and government together with community interests have continued to work together to prepare the consultation draft.
The draft standard currently includes provisions to minimise the risk of self-sustaining fires. In considering the fire hazards associated with some of these systems, the draft contains provisions that exclude certain battery systems from being installed inside domestic homes. They may be installed externally and adjoining to domestic homes provided certain fire related safety measures are met. These provisions have been included to try to safeguard against hazards during potential failure modes of a storage system, in the absence of available product standards. In arriving at this consultation draft, it is clear that different views exist amongst stakeholders as to whether the draft provisions are set appropriately and whether the benefits of emergent technology are appropriately balanced with community safety expectations. Given the level of interest in the introduction of battery storage in homes, public comment on the draft is sought in particular on Clauses 4.5.3 and Table 3.1 of the draft.
The release of the draft standard comes less than a week after the release of the Independent Review into the Future Security of the National Electricity Market (the Finkel Report) where it was noted that consumer demand could drive the number of on-site battery storage systems installed in Australian homes to more than 1 million by 2035. Why doesn’t Australia just use International Standards? There are no international electrical installation standards for battery energy storage systems.
The draft has been developed by Australian and New Zealand stakeholders who share a common regulatory and technical standards framework. The use of on-site battery storage systems is an emerging area of development internationally, with different countries setting different requirements within their own jurisdictions. The draft document references and aligns with a number of international standards particularly as they relate to system components. Who has developed this draft? The technical committee responsible for developing this document is EL-042 Renewable Energy Power Supply Systems and Equipment. The committee includes stakeholders from industry, government, academia and other interest groups, as listed in the attachment. What is the process from here?
All comments received during the 9 week public comment period will be considered in detail and resolved by the technical committee and, if substantive changes are made to the draft, the document will be released for a further period of consultation. Once all comments are resolved, a vote will be undertaken by the technical committee as to whether the document is published, or not. The use of all Australian Standards is voluntary and governments may choose to reference Australian Standards and other documents in regulation. Access the draft and submit comments through our Public Comment portal. All comments must be received by 15 August 2017.
