冠军蓄电池常用连接方式
冠军蓄电池广泛应用在比如UPS电源，EPS电源，直流屏，太阳能路灯等等！下面给大家简单讲诉一下冠军蓄电池是怎么来连接UPS电源的！
1、首先，头脑要清晰，安装环境要清净，人要少，不要有心事，连接方案要清楚，安装时手机建议关掉，不与客户聊天，更不能边安装边回答充满好奇心的客户喋喋不休的一连串的问题，这样会分神，很容易出事;


2、冠军蓄电池上架前要进行物理检查，并测量开路电压，以免返工;连接线的一端与电池相连时，另一端应进行绝缘保护或握在手心，防止搭到不该搭的地方，造成打火;


3、连接线的一端已接好，另一端再连接时应轻轻点一下要连接的极柱，即使连错了也只是在极柱上和连线上打一点火而已，不至于酿成大祸;或测量要连接的两点的压差，为零则可以连接;


4、两人同时连接时，对应的冠军蓄电池组应无连接或电位关系。因为两人为同电位(或随时变成同电位，如同时接触电池架)，各自连接的电池如存在电位差，则电池和二人形成回路，可能发生电击事故;


5、电池组串联完毕后，冠军蓄电池组的总正和总负之间电压比较高，在向MCCB(电池开关)连接时，每根线都应先连到MCCB，再连到对应的电池端;或在电池组中留一断点，完成MCCB与UPS蓄电池组的连接后再连接断点;对于多组并联的电池组，应每一组都留断头，并在MCCB端连接后分别用万用表检测极性再将断头连接。


由于电池内阻为毫欧级，因此采用常规的两端子测量方法测量误差较大，在此采用四端子测量方式。测量时两个端子施加一频率为
Because the internal resistance of the battery is millieu level, the conventional two terminal measurement method has great error, and the four terminal measurement method is adopted. At the time of measurement, two terminals are applied in a frequency.http://www.zhichengchampion.com

的恒定交流激励电流信号，另两个端子用于测量。测量工作原理图如图1所示，响应信号是指蓄电池注入交流恒流源后，在其两端测出的交流电压信号。而正弦信号是经D/A产生的作为压控恒流源的输入信号。
A constant AC excitation current signal and the other two terminals are used for measurement. The working principle diagram is shown in Figure 1. The response signal is the AC voltage signal measured at both ends after the battery is injected into the AC constant current source. Sinusoidal signal is generated by D/A as the input signal of voltage controlled constant current source.


蓄电池作为电源系统停电时的备用电源，已广泛的应用于工业生产、交通、通信等行业。如果电池失效或容量不足，就有可能造成重大事故，所以必须对蓄电池的运行参数进行全面的在线监测。蓄电池状态的重要标志之一就是它的内阻。无论是蓄电池即将失效、容量不足或是充放电不当，都能从它的内阻变化中体现出来。因此可以通过测量蓄电池内阻，对其工作状态进行评估。目前测量蓄电池内阻的常见方法有：
Battery as a backup power source when power system is outage, has been widely used in industrial production, transportation, communications and other industries. If the battery fails or the capacity is insufficient, it is possible to cause major accidents. Therefore, the on-line monitoring of the operation parameters of the battery must be carried out. One of the important signs of the battery state is its internal resistance. Whether the battery is going to fail, the capacity is insufficient or the charge and discharge is not proper, it can be reflected from its internal resistance changes. Therefore, the working state of the battery can be evaluated by measuring the internal resistance of the battery. The common methods for measuring the internal resistance of the battery are:http://www.zhichengchampion.com
（1）密度法
(1) density method
密度法主要通过测量蓄电池电解液的密度来估算蓄电池的内阻，常用于开口式铅酸电池的内阻测量，不适合密封铅酸蓄电池的内阻测量。该方法的适用范围窄。
Density method is used to estimate the internal resistance of the battery by measuring the density of the battery electrolyte, which is often used to measure the internal resistance of the open lead-acid battery, which is not suitable for the internal resistance measurement of the sealed lead-acid battery. The application of this method is narrow.
（2）开路电压法
(2) open circuit voltage method
开路电压法是通过测量蓄电池的端电压来估计蓄电池内阻，精度很差，甚至得出错误结论。因为即使一个容量已经变得很小的蓄电池，再浮充状态下其端电压仍可能表现得很正常。
The open circuit voltage method is used to estimate the internal resistance of the battery by measuring the terminal voltage of the battery. The accuracy is very poor, and even the wrong conclusion is obtained. Because even if a battery capacity has become very small, then the floating state of terminal voltage is still likely to be normal.
（3）直流放电法
(3) direct current discharge method
直流放电法就是通过对电池进行瞬间大电流放电，测量电池上的瞬间电压降，通过欧姆定律计算出电池内阻。虽然这种方法在实践中也得到了广泛的应用，但是它也存在一些缺点。如用该方法对蓄电池内阻进行检测必须是在静态或是脱机状态下进行，无法实现在线测量。而且大电流放电会对蓄电池造成较大的损害，从而影响蓄电池的容量及寿命。
The DC discharge method is to measure the instantaneous voltage drop on the battery by discharging the battery instantaneously, and calculate the internal resistance of the battery by Ohm's law. Although this method has been widely applied in practice, it also has some shortcomings. If we use this method to detect the internal resistance of battery, it must be carried out under static or offline state, and online measurement can not be achieved. Moreover, the large current discharge will cause great damage to the battery, which will affect the capacity and life of the battery.
（4）交流注入法
(4) AC injection method
交流法通过对蓄电池注入一个恒定的交流电流信号IS，测量出蓄电池两端的电压响应信号Vo，以及两者的相位差
In the AC method, a constant current signal IS is injected into the battery, and the voltage response signal Vo at both ends of the battery is measured, and the phase difference between them is measured.
