船用蓄电池的简单介绍
1、蓄电池是电池中的一种，它的作用是能把有限的电能储存起来，在合适的地方使用。它的工作原理就是把化学能转化为电能。它用填满海绵状铅的铅板作负极，填满二氧化铅的铅板作正极，并用比重为1.285的稀硫酸作电解质。在充电时，电能转化为化学能，放电时化学能又转化为电能。电池在放电时，金属铅是负极，发生氧化反应，被氧化为硫酸铅；二氧化铅是正极，发生还原反应，被还原为硫酸铅。铅蓄电池是能反复充电、放电的电池，叫做二次电池。它的电压是2V，通常把三个铅蓄电池单元串联起来组成一个外壳在一起的电池组使用，电压是6V。6个铅蓄电池单元组合在一起就是我们日常使用12V的蓄电池了。铅蓄电池在使用一段时间后要补充符合标准的电解液。

2、电瓶常常被船舶用做应急发电机、救生艇的启动电源；用于充放电板、主配电板、主机遥控和机舱监视报警系统的备用电源或者UPS电源箱以及火警等控制系统内部，电瓶的使用往往都是在紧急状态下发生的，日常的保养使设备随时处于可用状态是非常必要的。

3、船用蓄电绝大多数为铅酸蓄电池，也即是*段落所讲的电池工作原理。可以分为富液式和阀控式铅酸蓄电池，富液式蓄电池在日常保养中需要加注标准电解液的，而阀控式是不需要加注电解液的，也就是我们常说的免维护蓄电池。这种电池在控制箱中、UPS电源箱中是必须采用的。从结构上可以分为单体式和组合式。一般单体为2V的铅酸蓄电池在船上应用于应急充放电板提供自动化系统和应急照明电源。这种单体电池具有寿命长、容量大的特点，但造价高

3、日常保养中电机员需要了解的蓄电池参数：

和蓄电池相关的参数很多，这里只对和我们日常管理相关的加以简单介绍。

（1）船用电瓶的容量：通常设备容量会用KW或者表示。但是电池却不是这样的。在多数国家都是用AH--安时表示。他的意义是；以十小时放电率为标准。例如，90AH容量的电池，以10小时为基准，理论上可以连续10小时提供负载电流9安培，这只是理论上的数值，他和环境温度、电池性能等等因素还有很大关系。

（2）放电终止电压：电池放电过程中，终止电压在不同放电率和温度下会发生较大的变化，放电电流大可以允许较低数值的放电终止电压，小电流放电，终止电压要求较高数值。温度下降，电池容量降低，终止电压应该相应提高。实际管理中，以85%的电池额定电压为终止放电电压。如果继续过放电，电池温度、电池内阻会显著升高，严重缩短电池寿命。

（3）使用寿命：蓄电池每充电、放电一次，叫做一次充放电循环，蓄电池在保持输出一定的容量的情况下所能进行的充放电循环次数，叫做蓄电池的使用寿命。船舶电机员实际上是往往以电瓶使用的时间来判断电池的寿命是否终了，这是不正确的。电池应该从电池容量变化、放的时候终止电压等多方因素来确认。即使是投入使用时间不长的蓄电池如果得不到正确的保养和正确的使用同样也会报废。

（4）船用蓄电池的浮充电和均衡充电（也叫强充电）：

浮充电是电池组长期和充电器输出以及负载并联在线的，作为备用电源随时可以同时用的，串联的24V电池组浮充电的充电电压一般为26.4V-26.8V之间调整。例如;充放电板电池组、应急发电机电池组。有的船舶反应应急发电机蓄电池放电很快，两三天电压机会下降到22V甚至20V。需要更换电池组，经询问核实确认，电池充满电后充电器被关闭，这样应急发电机的控制箱电源只能由电瓶提供了，这说明使用者对必要的、正确的充电方式不了解。均衡充电（也叫强充电），串联的24V电池组均衡充电电压一般为28.2V左右：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。均衡充电的概念是在富液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“电池内不形成酸层，无需进行均衡充电“ ，均衡充电会对阀控式电池造成损害。对于富液式铅酸蓄电池，在均衡充电过程中应对电解液比重进行测量并对电解液液面进行必要到的调整，均衡充电一般应专人值守，控制充电时间，防止过充电。

船用蓄电池管理要点

以下管理中的注意事项和要点来自于船舶实际管理的总结。

1、蓄电池间的要求：对于富液式蓄电池组，应在室外控制照明、并张贴有禁止吸烟标志。室内应有良好的通风装置。对于没有单独蓄电池室的应急发电机间，富液式电池应该被存放于密闭的电池箱中，并且电池箱有独立的通风管直通室外，室内应有对蓄电池电解液进行配制工具。需要提醒的是，蓄电池工具箱中有的放置了普通手电筒，不具有防爆功能，这是画蛇添足的做法了。阀控式电池组不再此列。蓄电池间应存放灭火器。防护围裙、眼镜、橡皮手套、量具、比重仪、眼药水。不得存放与保养无关的其他物品。

2、每周应对蓄电池进行检查，测电压，保持蓄电池清洁，蓄电池的检查情况还应计入蓄电池记录簿，更换蓄电池时应将型号、容量、更换日期记入《蓄电池充电及养护记录薄；

3、应定期对蓄电池的接线进行必要的收件、清洁，涂凡士林油防止腐蚀。蓄电池室保持整洁，不可堆放无关杂物。

4、充电前，检查蓄电池室附近不能有动火作业，上面风筒保持开启状态，使蓄电池室保持良好的通风。

5、 蓄电池应经常放电、充电，如有两组蓄电池应对其编号，交换进行充电、放电，防止另一组长时间不充电被损坏，但切忌过放、过充以免损坏蓄电池。充电前应详细记录蓄电池的电压、充电的开始和结束时间。

6、蓄电池在运行放电后立即对其进行补充充电，若放电后蓄电池搁置时间很长，再充电时可能容量恢复不到原容量。

7、船用蓄电池在运行中，应经常检查充电设备，不能使蓄电池长期处于过充或欠充状态。这两种状态都会减少蓄电池寿命和容量。

8、 航行在寒冷海区或气温在摄氏零度以下时，每天应对蓄电池进行小电流充电，保持蓄电池正常温度，或者适当提高电解液的比重，以免冻裂、。

9、 免维护蓄电池（铅酸蓄电池）维护保养按产品说明书要求进行。可用充电电流和电压表（万用表）判断蓄电池工作状况。此种电池一般有变色电量指示球，实际使用中多出现过指示球卡死，晃动蓄电池即可恢复正常。

10、注意均衡充电时间控制，防止过充电。

11、充电过程中要检查测量串联的两块蓄电池的各自电压，如果相差较多，预示着其中一块电瓶已经老化严重或者内出现极板短路。

Guangzhou Bei longs to provide long-term ship maintenance free battery battery, can be used as a ship, ship start, boat battery, power source, ship emergency lighting, communication equipment and other major power, optional marine battery brand: sailing ship battery, camel ship cruise ship with battery, storage battery and other well-known battery brand Changqing the brand, most marine storage battery with 6-CQW-210, 6-CQW-200, 6-CQW-150, 6-CQW-120, 6-CQW-100, 6-CQW-90, 6-CQW-70 these models, exhaust type maintenance free lead-acid batteries, but the starting current is above 1000CCA, MF on behalf of free maintenance, large yacht generating units, instant start, Guangzhou Bei rance company specializes in marine batteries, the supply of the domestic large shipyard, shipyard, reasonable price, timely delivery of adequate inventory.

A brief introduction of marine battery

1, the battery is a kind of battery, its role is to be able to store a limited amount of energy, in the right place. It works by converting chemical energy into electrical energy. It is filled with spongy lead of lead anode, fill two lead lead as cathode and electrolyte for dilute sulfuric acid with the proportion of 1.285. When charging, the electric energy can be converted into chemical energy, and the chemical energy can be converted into electric energy during the discharge. Battery discharge, metal lead is the anode oxidation reaction, the oxidation of lead sulfate; lead oxide cathode is two, reducing reaction, reduction of lead sulfate. Lead acid battery is a battery that can be recharged and discharged repeatedly. It is called the two battery. Its voltage is 2V, usually the three lead battery units are connected in series to form a shell with a battery pack, the voltage is 6V. The combination of 6 lead-acid batteries is our daily use of 12V batteries. Lead acid batteries to be used in a certain period of time to supplement the standard electrolyte.

Marine battery, maintenance free marine battery

2, the battery was often used to start the emergency generator, power supply as the lifeboat ship; for internal standby power supply switchboard main switchboard, remote control and engine room monitoring alarm system or UPS power supply box and the fire control system, battery usually occurs in the emergency condition, daily maintenance the equipment is available at any time is very necessary.

3, marine storage for the vast majority of lead-acid batteries, battery is the working principle of the first paragraph said. Can be divided into fooded and VRLA batteries, fooded batteries need to add standard electrolyte in the routine maintenance, the valve control type is not need to add electrolyte, is what we often say that the maintenance free battery. The battery must be used in the control box and the UPS power supply box. From the structure can be divided into single and combination. General single 2V lead-acid batteries on board used in the emergency switchboard and emergency lighting power supply automation. The single battery has the characteristics of long service life and large capacity, but the cost is high

In 3, the daily maintenance of the motor needs to understand the battery parameters:

And battery related parameters, here only to our daily management related to a brief introduction.

(1) the capacity of marine storage battery: usually the equipment capacity will be KW or. But that's not the case. In most countries are indicated by AH-- ah. His meaning is to ten hours discharge rate as the standard. For example, 90AH capacity battery, 10 hours for the benchmark theory can be 10 hours of continuous load current of 9 amps, this is only a theoretical value, there is a great relationship between him and the factors of environmental temperature, battery performance and so on.

(2) the end of discharge voltage: battery discharge process termination voltage will change greatly at different discharge rate and temperature, discharge termination voltage and discharging current allows a low value, low discharge current, terminal voltage requirements of high value. The temperature drops, the battery capacity decreases, and the termination voltage should be increased accordingly. Actual management, with 85% of the battery rated voltage for the termination of the discharge voltage. If you continue to discharge, the battery temperature, the internal resistance of the battery will significantly shorten the battery life, serious.

(3) the service life of battery charging and discharging: each time, called a charge discharge cycles, the battery can keep the output in a certain capacity under the condition of charge discharge cycles, called battery life. In fact, the ship is often used to determine the battery life of the battery to determine whether the end of the battery, which is not correct. The battery should be changed from the battery capacity, put the termination voltage and other factors to confirm. Even if the battery is not used for a long time, if not properly maintained and used properly, it will also be scrapped.

(4) floating charge and equalizing charge for marine battery (also called strong charge):

The floating charge battery and charger output and long-term load parallel online, as a standby power supply at any time can be used at the same time, charging voltage of 24V battery charging floating series is usually between 26.4V-26.8V adjustment. For example; the switchboard battery, emergency generator battery. Some ships respond emergency generator battery discharge is very fast, the two or three day voltage drops to 22V or even 20V. Need to replace the battery, by asking for confirmation, full battery charger is closed, so only the emergency generator control box power provided by the battery, this shows that users do not understand the necessary and proper charging. Balanced charge (also called a strong charge), series 24V battery equalization charging voltage is generally 28.2V
