CENELEC发布“EN 50342-6:2015/A1:2018-蓄电池及蓄电池组”新标准

发布时间: 2019-01-07 11:01:02   审校:睿智  

如果你要想看看世上正发生何种变化,不妨先看看你的车。当今世界,汽车无处不在,拥有全球性市场与复杂的供应链。汽车制造商需时时应对不断涌现的新需求,拥抱快速的变迁与创新性解决方案。因此,汽车行业是最能捕捉并预见科技与社会创新的领域之一。

汽车电池恰恰是这一创新能力的体现。从为环保而提高能效到提升驾驶员安全度,电池在汽车的性能架构中具有战略性地位。因此,不难理解行业为汽车电池规定了一系列特殊标准,且这些标准还在不断制定和更新。

其中,欧洲电工标准化委员会(CENELEC)最近发布了EN 50342-6:2015/A1:2018铅酸起动蓄电池-第6部分:电池的微循环应用这项新标准。这一欧洲标准是EN50342铅酸起动蓄电池系列标准的一部分,适用于标定电压12V的起动蓄电池,主要为内燃机起动、照明和内燃机车辆的辅助设备提供动力。

此项标准范围内的蓄电池应用于具备起动-停止功能(Start-Stop)的车辆:这种车的内燃机在车辆彻底停止或怠速行驶、无需内燃机时是关闭的。当然,若要提高起动-停止系统能效,需与普通起动电池完全不同的特殊类蓄电池。该标准范围内的全部电池需满足EN 50342-1:2015标准验证的基本功能。

EN 50342-6:2015/A1:2018是一个修正案,该修正案提供了该标准的新分类,以纠正其错误并避免对定义的误读,进而提升电池使用的安全性。这一修正案的重要性不仅局限于欧洲:由于汽车市场本质上的全球化特征,该修正案被普遍认为适用于全球及欧洲以外的制造商,以便能够进入欧洲单一市场。比如,国际电工委员会(IEC)起草的一项IEC60095-6标准项目就以EN 50342-6标准程序为基础。此外,美国汽车工程师协会(SAE)也以EN 50342-6标准为基础撰写过标准。

EN 50342系列标准都是属于CLC/TC 21X “蓄电池及蓄电池组”技术委员会范围内,其目标就是开展蓄电池及蓄电池组标准化行动,将IEC/TC 21/SC 21A文件落实到CENELEC标准中,准备产品标准及安全标准,并将产品的环境要求纳入考量范围。目前,TC 21X的秘书处工作由德国电工委员会(DKE)代理。TC CLC/TC 21X已开始EN 50342的下一项修订工作,正对新的测试流程进行验证。

New CENELEC standard: EN 50342-6:2015/A1:2018 – Secondary cells and batteries

If you want to see how the world is changing, look at your car. The car industry is traditionally among the sectors that are the most involved in capturing and foreseeing technological and social innovations: due to their omnipresence, global market and supply chain complexity, carmakers are open to rapid changes and innovative solutions that respond to necessities continuously emerging in society.  

An example of this ability to innovate can be found in car batteries. From ensuring energy efficiency and thus the respect of the environment to increasing the drivers’ safety, batteries have a strategic importance in a car’s functioning. It is no surprise, then, that car batteries have a series of specific standards on them, that are constantly developed and updated. 

Among them, CENELEC has recently released EN 50342-6:2015/A1:2018 ‘Lead-acid starter batteries - Part 6: Batteries for Micro-Cycle Applications’. This European Standard, part of the EN 50342 series on Lead-acid starter batteries, applies to ‘starter batteries’ with a nominal voltage of 12 V, used primarily as power source for the starting of internal combustion engines (ICE), lighting and also for auxiliary equipment of ICE vehicles. 

The batteries under the scope of this standard are used in so-called Start-Stop vehicles: in cars with this special capability, the internal combustion engine is switched off during a complete vehicle stop or during idling without the need of supporting the vehicle movement by the internal combustion engine. Naturally, if this system allows for an increase in energy efficiency, it requires special types of batteries, as they are stressed in a completely different way compared to classical starter batteries. All batteries under this scope need to fulfil basic functions, which are tested under application of EN 50342-1:2015.

EN 50342-6:2015/A1:2018 is an amendment providing new classifications to this standard, part of the EN 50342 series, in order to correct errors and avoiding misunderstandings in definitions, thus increasing safety in the use of batteries. Its importance goes beyond Europe: due to the substantial globalised character of the automotive market, it is a standard which is widely referred to internationally, as well as by non-European producers, in order to be able to access the European Single Market. For example, IEC (the International Electrotechnical Commission) started a project for IEC 60095-6 based on EN 50342-6 procedures. Additionally, SAE (the Society of Automotive Engineers) initiated a document based on EN 50342-6.

All standards developed in the EN 50342 series are under the scope of CLC/TC 21X ‘Secondary Cells and Batteries’, whose aim is to develop standardization activities for secondary cells and batteries, implement IEC/TC 21/SC 21A documents into CENELEC standards, prepare Product Standards and Safety Standards and consider Environmental Requirements for the products. The Secretariat of TC 21X is currently held by DKE, the German Electrotechnical National Standardization Body. TC CLC/TC 21X has already started working on the next revision of EN 50342 and is validating new test procedures.
