使电池系统发挥最佳状态

使电池系统发挥最佳状态

Getting the best from a battery system

Nicola Corradin, FIAMM

译者说

电池在数据中心等行业的作用至关重要，必须保证电池系统在需要时是有效且及时的。因而电池的设计选择需要考虑电池的老化可能、所处区域电力的可靠性、温度波动的影响等，电池系统通常是冗余的，但其所处环境及配套却不完全相同，不能简单复制粘贴。随着电池技术的发展，电池的维护要求可能越来越低，但不管在哪里，都需要对其进行日常维护。本文对以上内容进行总结和探讨，希望给大家带来一些收获。

现今每个人都在谈论电池，在世界的绿色转型过程中，电池正成为越来越重要的组成部分。电动汽车、能源存储、电力通信，当然还有数据中心，所有这些行业或多或少都需要电池。

Everyone is talking about batteries today. They are becoming an increasingly important component in the transition to a greener world. Electric cars, energy storage, telecommunication and of course, data centers. They all need batteries in one way or another.

尽管如此，大多数人都不太了解电池内部的工作原理，也不知道如何充分利用电池。电池有时是最后才考虑的要素之一。但是，对电池及其环境进行良好的前瞻性规划将有助于确保设备的可靠性和长寿命。

Despite all of this most people don’t know very much about what goes on inside a battery and how to get the best from it. Batteries are sometimes one of the last elements to be considered. But good forward planning of the battery and its environment will help to ensure reliability and long life of the asset.

在考虑安装时，重要的是要考虑电池的位置，以及如何维护和监测房间的环境。电池室的温度变化会影响电池系统的寿命。

When planning an installation, it is important to consider where batteries will be situated and how to maintain and monitor the environment of the room. A battery room with variable temperatures will affect the life of a battery system.

本文给出了在规划数据中心及其备用电源系统时应考虑的一些指导方针。

This article provides a few guidelines that should be considered when planning a data center and its backup power system.

一个电池备用系统必须可以运行多年，并随时准备释放电能。电池是整个系统的一部分，大多数数据中心会使用发电机作为辅助，但问题是发电机需要一段时间才能达到最大功率，这就是电池发挥作用的地方，作为瞬时动力供电，直到发电机到最大功率。

A battery backup system must operate for many years and be ready for instantaneous release of energy. A battery is a component of the overall system. Most data centers use auxiliary gensets. The problem is that they need a time interval to reach full power. This is where batteries come in and play the role of instant power.

当选择电池系统时，以下正是需要考虑的关键要点。

When choosing a battering system, the following are some of the critical elements that need to be considered.

计划好电池寿命耗尽前的性能

Plan for battery performance at the end of their specified life

电池是一种把化学能转换为电能的装置，该反应使得电荷从一种物质转移到另一种物质，他们被称作阳极和阴极，通常由一种被称作电解质的材料进行传递，这种能量的转移被称为充电或放电，电池的放电和充电是一个循环。

A battery is a device that converts chemical energy into electrical energy. The reaction involves the transfer of electrons from one material to another. This is called an anode and a cathode, and the transfer is carried out usually by a material known as an electrolyte. This transfer of energy is known as a charge or discharge. A discharge and recharging of the battery cell is a cycle.

由于化学特性的原因，所有的电池都会随着时间推移而丧失性能，这被称为老化。当设计以及确定一个系统时必须考虑老化因素，因为电池需要能够支撑系统整个生命周期的设计负载。例如，一个电池系统，设计为服务十年，就必须能支撑相应负载满足十年服务周期。

All batteries, due to the characteristics of the chemistry, are subject to loss of performance over time. This is called ageing. This ageing factor must be considered when designing and specifying a system since a battery needs to be able to support the design load of the system over life. For example, a battery system, designed for 10 years’ service, must be able to support the load at the end of its 10 years’ service.

考虑市场可靠性

Consider mains power reliability

在世界各地的电力中，由设施生产的电力质量和稳定性各不相同，一些地区可能一年只停电几次，一次只持续几分钟，然而另一些地区则频繁停电并且持续很长时间。这对电池的影响是十分巨大的。

Throughout the world power, the quality and consistency of power generated by the utility differs. Some areas may have only a few power outages a year, and last just a few moments, while others are frequent and last for a long period. The implications of this for a battery are considerable.

频繁的电力中断将对系统有很高的要求，从而对电池和发电机组的循环寿命提出了疑问。频繁以及长时间的电力中断可能意味着电池系统必须能够承受住这许多次循环，其中很多时候电池可能不能完全放电，从而会使电池工作强度大，进行部分充电并且需要快速给系统充电。

Frequent power outages will have heavy demands on the system and consequently the battery and genset, which raises the question of cycle life. Frequent power outages and for long duration can mean that the system has to be able to withstand many cycles, many of which may not be full discharges. This can subject a battery to heavy workload and partial charges and the need to recharge the system rapidly.

温度在电池寿命和性能方面起着重要作用

Temperature plays a major role in battery life and performance

温度在电池寿命方面起着重要作用。一般来说，高温会加速内部化学反应从而降低电池寿命，这个规律适用所有化学电池。在低温下，通常低于零度时，电池性能会受到影响，我们大多数人都有在寒冷天气发动汽车的经历。

Temperature plays an important role in the life of a battery. In general, high temperatures lower the life of a battery as they speed up the internal chemical reaction. This applies to all chemical batteries. At lower temperatures, usually below zero, the performance of a battery is impeded. Most of us have experienced this with starting a vehicle in freezing conditions.

在考虑进行安装时，考虑电池的位置以及监控房间的温度是至关重要的，电池室的温度波动会影响电池系统的寿命。

即便只提高几度，但经过几年后这也会降低电池的运行寿命。因此考虑电池放置房间需要进行仔细的设计规划。

Even a few degrees of higher temperatures, but over several years will shorten the operating life of the battery. It therefore makes for good design planning to consider the room where the batteries will be situated.

系统冗余:电池相同，需求却可能不同

System redundancy: A duplicated battery requirement may be different

正如本文开头所说，电池是系统的一部分。这一点经常被忽视。数据中心包括电池，在计划中都是冗余的。这意味着每个系统都会被复制，而且通常在完全不同的位置。

Batteries, as stated at the beginning of this article, are components of a system. This is often overlooked. Data centers, including batteries, all plan for redundancy. This means that every system is replicated, and often in very different locations.

因此，当考虑安装新的电池系统时，仅复制安装是完全不够的，环境因素如布局、电源以及运行温度可能是不同的。

So, when planning a battery system for a new installation, it is not enough to duplicate the installation. The environmental factors such as layout, power and operating temperature may be different.

一个好的安装解决方案必须考虑到这些因素，重要的是要考虑到数据中心的第二次电池安装可能有不同的环境和操作需求。因此，每个房间都需要单独考虑。

A good installation solution must take these factors into consideration. It is important to consider that a second battery installation for a data center may have different environmental as well as operating needs. Therefore, each room needs to be considered individually.

计划服务的定期步骤

Plan a service routine procedure

现在许多电池被归类于免维护，这些电池设计时将电解液密封在电池内部。以前，电解液需要定期补充并进行一般维护检查。这并不意味着电池在其特定的寿命内可以被忽视。

Many batteries today are classified as ‘maintenance-free’. These batteries are designed with an electrolyte sealed inside the battery; previously the electrolyte needed to be periodically ‘topped-up’ as well as a general maintenance inspection. This does not mean that the batteries can be ignored over their specified life.

在Uptime Institute最新的全球数据中心调查中确定了这个行业的主要事件和问题，其中一个突出的领域——但不是第一个——是电池。他们发现，大多数电池故障是由于缺乏定期维护。但这意味着什么呢?

In the latest Uptime Institute global data center survey which identifies major incidents and issues in the industry, one of the areas highlighted ‒ but not the first ‒ was batteries. They identified that most battery failures were due to lack of routine maintenance. But what does this mean?

电池经常放置于站点的单独位置，电池系统会安装有充电装置并使其在指定的运行条件下确保运行一段时期。

Batteries often exist in a separate location on a site. The system is installed with a charger and specified for a period of guaranteed operation at specified operating conditions.

免维护电池不需要高水平的维护，但他们需要定期巡视和检查以确保所有电池都在工作。

Maintenance free batteries do not need a high level of maintenance, but they do need periodic inspections and checks to ensure that all batteries are performing.

一个大型电池系统可能由数百个单独的电池构成，所有电池连接在一起，一个或多个异常的电池会损坏系统。对电池系统进行定期检查不需要太长时间但这应该成为任一数据中心日常工作的一部分。

A large battery system can consist of hundreds of individual batteries, all linked together. The poor performance of one or more batteries can damage the system. A routine inspection of the battery system does not take much but it should be done as part of the operational routines of any data center.

定期服务可以避免未来出问题。大部分的电池供应商，例如FLAMM能源公司，提供一种监测解决方案来检查电压和温度，这可以做一个高级预警系统。

Routine service can avoid future problems. Most battery suppliers, such as FIAMM Energy Technology, offer a monitoring solution that checks voltage and temperature and can act as an advanced warning system for problems.

检查表

The checklist:

系统寿命: 计划内寿命结束时的性能需求

System life: Plan for performance needs at the end life
