储能系统要想安全？必须要做到这13个关键点！

最近的电池安全事故频发引起了业界广泛关注。因此在选择储能系统时，安全是需要考虑的关键因素。鉴于市场上针对储能系统客户有多种选择，我们愿意给出建议，引导买家选择更加安全的储能系统和储能产品。

Recent battery incidents have made the news. For this reason, the topic of safety has re-emerged as a critical factor in selecting an energy storage system. Given numerous market alternatives, it is our belief that a proper search should lead buyers to the safest choices.

选择正确的电芯

从安全角度而言，我们将原始安全性（可以采取哪些措施来预防事故发生）与二次安全性（如何更好地控制和管理事故进展）区分开来。原始安全性直接与储能系统的电芯相关。

In terms of safety, we differentiate primary safety (what can be done to prevent incident occurrence) from secondary safety (how to better control and manage hazards once an incident is underway). Primary safety is directly linked to the cell itself.

行业有不同类型的电芯可供选择，每种都有其优点，但最重要的是要选择符合IEC62619标准的电芯。正如其标题所述，“含碱性或其他非酸性电解质的二次电池和电池组——工业级二次锂电池和电池组的安全要求”，该标准专门用于确保电芯的安全性。

There are different kind of battery cells; each with its advantages. But the most important to consider is that the cell is compliant with the IEC62619. As mentioned in its title, “Secondary cells and batteries containing alkaline or other non-acid electrolytes – Safety requirements for secondary lithium cells and batteries, for use in industrial applications,” this standard is dedicated to the safety of the cells.

确保模组、电柜和集装箱的安全集成

对于模块和电柜：确保电池符合UL 1973和IEC 62619标准。

For modules and racks: Make sure the battery meets the UL 1973 and IEC 62619 standards.

选择获得UL9540A认证的电池意味着该储能系统通过了UL机构模拟热失控的测试，以检查火灾是否会蔓延。

Selecting a battery, which is UL9540A approved, means the system has been tested, simulating a thermal runaway incident, to check that the fire doesn’t propagate.

考虑到机械、热、电和安全等约束条件。所有适用于船舶、运输或固定式应用的系统都要经过广泛的测试和认证过程。

投资安全的电池管理系统和能源管理软件

使用安全且符合标准的组件是确保电池具有最高安全性水平的必要第一步；但是，如何使用电池也非常关键。这就是为什么电池管理系统（BMS）应确保电池使用不会超出其极限。为了保证这种功能安全性，BMS必须通过IEC61508进行认证，这是与电气/电子/可编程电子系统功能安全相关的标准。

Using safe and standard compliant components is the mandatory first step to ensure the highest possible safety level; however, how the battery is used is key too. That’s why the battery management system (BMS) should ensure that the battery is not pushed beyond its limits. To provide this functional safety, the BMS must be certified according to IEC61508, the standard for functional safety of electrical/electronic/programmable electronic safety-related systems.

BMS生成大量数据，这些数据由能源管理软件（EMS）读取，在本地保存并定期备份到安全的云系统中。所有这些数据都可以用于电池的失效或偏差分析以及用于系统优化。

The BMS generates a huge amount of data that are read by the energy management software (EMS), saved locally and regularly backed-up to a secure cloud system. All these data can be used for analytic purposes to detect possible battery misbehaviour or deviations at an early stage as well as optimise system operation.

系统分区更好地遏制事故发生

将储能系统在固体外壳内分区有助于防止火灾的发生和蔓延。

Dividing the energy storage system and partitioning the battery system in solid enclosures helps to prevent a fire incident from spreading to an entire site.

LeBlock是Leclanché全新的、安全的、模块化的、可扩展的、即插即用型的能量存储解决方案。它的设计旨在简化物流并降低总成本和碳足迹。

LeBlock is Leclanché’s new, safe, modular, scalable, plug & play energy storage solution. It has been designed to simplify logistics and reduce total costs and carbon footprint.

电池模组放在高强度的集装箱外壳里，这有助于防止火灾的蔓延。

With LeBlock, battery modules are placed in compact enclosures based on robust container technology. This helps to contain a potential fire within each block.

外壳具有绝佳的耐火性和隔热性能，可以减少辅源的消耗，进而可以保证电池独立于外部环境，在一定温度下运行（通常在20到23°C之间）。

The enclosures are highly fire resistant, providing the thermal insulation needed to minimise the auxiliary energy consumption to maintain the battery at a certain temperature – typically between 20 and 23°C– independent of the outside temperature.

选择合适的消防系统

储能系统分区提供了一种被动提高安全性的方法，但也有一些主动的方式来对抗火灾。消防系统的目标是防止非电池火灾蔓延到电柜中的其他电芯，从而防止涉及少数电芯的小事故变成大规模火灾，其后果可能波及到整个电柜或集装箱。标准的消防系统系统包括烟雾和温度传感器和气溶胶系统，在火灾发展到一定程度时会自动触发。

Whereas partitioning provides a passive way to improve safety, there are some active ways to fight fires. The goal of a fire suppression system is to prevent a non-battery fire from reaching other cells in the block – preventing a small incident involving a few batteries from turning into a large-scale fire whose consequence could be the replacement of the entire container – or worse, an entire site. A standard fire detection and suppression system consists of smoke and heat detection sensors integrated, with automatic activation, into an aerosol extinguishing system.

使用泄爆板保障员工安全

人员安全至关重要。即使储能场地得到安全保障，员工在维护和例行系统检查时也会在附近工作。他们可能会站在火灾或爆炸发生时的储能电柜和集装箱旁边。为了保护他们的安全，泄爆板能够将内部火灾产生的压力从顶部泄出，确保在该区域工作的人们免受侧面爆炸的伤害。

The safety of personnel is key. Even if a site is secured, employees will be working nearby for maintenance and routine system checks. They could be standing next to a battery block when a fire or explosion takes place. In order to protect their safety, a deflagration panel enables the force of any internal pressure to be directed upwards. It ensures that people who are working in the area are protected from sidewards explosions.

泄爆板的设计和制造要符合NFPA 68标准。
