阀控式密封铅酸蓄电池就是VRLA电池。它诞生于20世纪70年代,到1975年时,在一些发达国家已经形成了相当的生产规模,很快就形成了产业化并大量投放市场。这种电池虽然也是铅酸蓄电池,但是它与原来的铅酸蓄电池相比具有很多优点,而倍受用户欢迎,特别是让那些需要将电池配套设备安装在一起(或一个工作间)的用户青睐,例如UPS、电信设备、移动通信设备、计算机、摩托车等。这是因为VRLA电池是全密封的,不会漏酸,而且在充放电时不会象老式铅酸蓄电池那样会有酸雾放出来而腐蚀设备,污染环境,所以从结构特性上人们把VRLA电池又叫做密闭(封)铅酸蓄电池。
The valve controlled sealed lead acid battery is the VRLA battery. It was born in 1970s, by 1975, in some developed countries has formed a considerable scale of production, and quickly formed the industrialization and a large number of market. Although the battery is also a lead-acid battery, it has many advantages compared to the original lead-acid battery, and is popular with users, especially for users who need to install the battery matching equipment together (or a workroom), such as UPS, telecommunication equipment, mobile communication equipment, computers, motorcycles, etc. . This is because the VRLA battery is fully sealed, does not leak acid, and does not have acid fog like the old type lead-acid battery when charging and discharging the corrosion equipment, polluting the environment, so the VRLA battery is also called closed (sealed) lead-acid battery from the structural characteristics.

  为了区分,把老式铅酸蓄电池叫做开口铅酸蓄电池。由于VRLA电池从结构上来看,它不但是全密封的,而且还有一个可以控制电池内部气体压力的阀,所以VRLA铅酸蓄电池的全称便成了“阀控式密闭铅酸蓄电池”。
To distinguish the old lead-acid battery called open lead-acid battery. Since the VRLA battery is structurally, it is not only fully sealed, but also a valve that can control the pressure of the gas inside the battery, so the full name of the VRLA lead-acid battery has become a "valve controlled sealed lead acid battery".

  风帆蓄电池市场成长仍值得期待。
Sailing battery market growth is still worth looking forward to.

  阀控密封铅酸蓄电池具有免维护、绿色环保的特点,未来几年其在以下几大市场推动下仍有望保持快速成长:
The valve regulated lead-acid battery has the characteristics of no maintenance and green environmental protection. It will continue to grow rapidly in the following years.

  一是我国通信基站的大规模建设与维护,国内移动运营商未来几年内建造3G及GSM基站年总共需要电池量约1,180万kVAh(公司目前产能为210万kVAh/年);
One is the large-scale construction and maintenance of China's communication base station. In the next few years, 3G and GSM base stations in China need a total of about 11 million 800 thousand kVAh (the company's current capacity of 2 million 100 thousand kVAh/).

  二是国内通信行业原有蓄电池的维护、替换所需年均电池量约860万kVAh;
Two is maintained, the domestic telecommunications industry to replace the original battery required annual battery weight of approximately 8 million 600 thousand kVAh;

  三是海外新兴区域通信市场与风光可再生能源、电动汽车等新兴领域,都将带动阀控密封铅酸蓄电池需求持续增长。
Three is the emerging areas of overseas emerging areas, renewable energy, electric vehicles and other emerging fields, which will drive the continued growth of valve controlled sealed lead-acid batteries.

  阀控式密封铅酸电池(以下简称阀控式电池)由于具有节省投资、安装简便、安全可靠、使用方便等特性,在实际应用中被大量使用。但由于对其使用要求缺乏了解,并沿用旧的均衡充电制度,对电池造成较大的危害。
The valve controlled sealed lead acid battery (hereinafter referred to as valve controlled battery) has been widely used in practical application because of its characteristics of saving investment, easy installation, safety and reliability, easy to use and so on. However, due to the lack of understanding of its requirements and the use of the old equalization charging system, it will cause great harm to batteries.

  1.取消均衡充电的理由
1. cancellation charge balance reasons

  (1)何谓均衡充电
(1) what is the charge balance

  所谓均衡充电,就是均衡电池特性的充电,是指在电池的使用过程中,因为电池的个体差异、温度差异等原因造成电池端电压不平衡,为了避免这种不平衡趋势的恶化,需要提高电池组的充电电压,对电池进行活化充电。
In order to avoid the deterioration of the imbalance trend, it is necessary to increase the charge voltage of the battery group and activate the battery to charge the battery.

  (2)无须均衡充电的理由
(2) no reason for equalizing charge

  首先,均衡充电的概念的概念是在老式铅酸电池使用中提出的目前大的多数的阀控式电池都明确提出“电压均衡、化成彻底”。而“电池内不形成酸层,无需进行均衡充电”。对于2.4V单体电池的充电电压的定义是加速充电,即“FASTCHARGE”,而非“EQUATION”。
First of all, the concept of balanced charging is that the current large majority of valve controlled batteries proposed in the use of old type lead-acid batteries have explicitly proposed "voltage equilibrium and complete conversion". And no acid layer is formed inside the battery, so there is no need for equalizing charging. The definition of the charging voltage of 2.4V battery is to accelerate charging, that is, "FASTCHARGE" instead of "EQUATION".

  其次,均衡充电会对阀控式电池造成损害。均衡充电电压对于大多数电池来说,都是较高的浮充电压。此时,大多数正常电池都处于过充电状态。不能复合的气体在电池内部形成一定的压力,压力超过安全控制阀阀值时,阀门打开,气体从控制阀中排出。
Second, equalizing charge will cause damage to the valve control type battery. Balance charging voltage for most batteries, are higher float voltage. At this point, most of the normal batteries are in the state of over charging. The complex gas can form a certain pressure inside the battery. When the pressure exceeds the threshold of the safety control valve, the valve opens and the gas is discharged from the control valve.

  在以前的电池维护中,伴随着均衡充电的过程是进行电池比重的调整,也就是说采用添加蒸馏水的办法补充水量,以保持电池的均衡性。但在免维护电池中,在现有的维护制度下是不加水的,这样一来,将不可避免造成电池的失水、电池干枯。
In previous battery maintenance, the proportion of the battery was adjusted with the equilibrium charging process, that is, adding distilled water to supplement the amount of water in order to maintain the balance of the battery. But in the maintenance free battery, there is no water added under the existing maintenance system, which will inevitably lead to battery loss and battery withering.
