蓄电池阻抗测试仪ＢＩＴＥ介绍
蓄电池抗阻测试仪BITE是采用物理测试的方法代替化学检验的方法，以确定蓄电池是否恶化或已经损坏。
我们知道，理论上理想电压源的内阻抗为零，所以对于性能良好的蓄电池其内阻抗是很小的，但是，随着蓄电池运行时间的加厂，和一些诸如环境和恶劣运行条件等因素的影响，蓄电池的性能便会渐渐劣化，性能转坏的蓄电池与理想电压源相去甚远，在物理状态上的表现是内阻抗的增加。BITE正是基于这种原理对蓄电池性能进行评定的。
对蓄电池性能进行评定的传统方法是将蓄电池的性能作出判断，一般地导电度越大，含杂量少的蓄电池的内阻抗小，反之，蓄电池的内阻抗大，则蓄电池的导电度小，含杂量大。BITE测试方法与传统化学检验方法是歹殊同归的，但二者在测试过程上却有很大差别，
对一组蓄电池（一般是１４４块电池）进行化学检验，必须将蓄电池退出运行，并将其放电，然后由数个技术人员工作上好几天才能检验完毕，得出结果，而这种仅是针对蓄电池的。而对相同的蓄电池组，采用蓄电池抗阻测试仪，蓄电池既不必退出运行，更不必放电，一个技术人员仅用十五分钟即可得到极精确的打印结果，从结果中不但能得到对蓄电池性能优劣的判断，也可发现电池间连接状况的好坏。
BITE是世界上唯一采用新的观念对蓄电池性能进行测试的先进仪器，设备一问世便风靡美国，随后波及欧洲与南非，近年来，随着美国AVO设备一同进入中国市场，用户深为其便捷、精确的性能所白折服。
• Determines condition of lead-acid and NiCd cells up to 7000 Ah
• On-board Pass/Warning/Fail indications
• Robust, repeatable instruments
• On-line testing
The BITE 2 and BITE 2P Battery Impedance Test Equipment determine the condition of lead-acid and nickel-cadmium cells up to 7000 Ah. An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions and more. The case of the BITE 2P consists of both the transmitter and a carrying case for all of the standard accessories and some of the optional accessories, in an all-in-one unit. The BITE 2 and its accessories fit into a sturdy canvas case with a shoulder strap.
The instruments work by applying a test current across the battery string while on-line, then measuring the total current (ac ripple + test current) and the voltage drop of each cell/jar. It then calculates the impedance. They also measure dc voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string's electrical path from terminal plate to terminal plate.
The BITE 2 and BITE 2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and ac ripple current, assist in determining the overall condition of battery systems. Megger recommends that impedance measurements with the BITE 2 or BITE 2P be made part of a battery maintenance program with readings taken and recorded semiannually for flooded batteries and quarterly for VRLA.
Unlike load cycle testing that involves substantial downtime and repeated discharges, using the instruments require no battery discharge, nor do they stress the battery in any way compared to other techniques. With a test time of less than 20 seconds for each cell and intercell connector, one person can easily, quickly, and precisely measure internal cell impedance, dc terminal voltage and intercell connection resistance without taking the battery system off line.
Naturally, everything you need to perform these tests is included with the basic instruments. There is a full line of optional accessories to enhance the capabilities of the BITE 2 and BITE 2P. Both have the ability to download to a PC for data interpretation. Additionally, the BITE 2P has a built-in printer to review the active test but also to leave a hard copy record at the site.
