Internationally, the battery internal resistance test has been widely used in the daily maintenance of the battery, replacing the previous voltage detection, because the internal resistance value reflects the internal parameters of the battery, and the internal resistance measurement has been recognized internationally as accurate and quick to judge the battery health An important means of the situation. International Electrotechnical Engineering IEEE1188-1996 formulated the standard of "regularly test battery internal resistance to predict battery life" for battery maintenance. The Post and Telecommunications Product Quality Inspection Center of the Ministry of Information Industry of China also proposed relevant specifications for battery internal resistance. IEEE1188-1996 stipulates that when the internal resistance of the battery is greater than 20% of the base value, a further check discharge test must be performed.
RBT-2000 can perform online measurement on the battery without discharging, with high safety, simple wiring and convenient operation. It is widely used in electric power, communication, railway and financial units. It solves the problem of high difficulty and high risk of battery maintenance for maintenance personnel. It is an ideal portable battery maintenance instrument.
Online testing of UPS battery power supply performance, accurate finding of UPS battery failure hidden dangers, online rapid detection of battery internal resistance and capacity, simple operation and convenient carrying.
1. Main functions of RBT-2000
1. The instrument has two measurement methods, online/offline, and can measure the voltage, internal resistance, connection resistance, and capacity of the single battery.
2. Adopt standard DC internal resistance test method: separate the voltage line, current line and data acquisition line, which can effectively reduce the error of contact resistance.
3. The test current reaches more than 42A to ensure test accuracy. The high-current test internal resistance can effectively resist the ripple interference of the battery test environment.
4. The instrument can set the upper and lower limits of voltage, upper and lower limits of internal resistance, nominal capacity, nominal voltage, number of batteries, internal resistance, service life, alarm switch and other parameters
5. A variety of battery parameters can be set and saved. During field testing, users only need to select the corresponding battery parameters without setting them one by one.
6. It can automatically estimate the battery capacity, can measure 0-15V batteries of various specifications, and the range is 0-6000AH.
7. It has alarm functions such as wiring error, abnormal battery, and battery failure.
8. With automatic test, manual test, voltage test, retest and other test modes
9. 9 different battery parameter modes can be set to facilitate testing of different types of batteries.
10. With analysis software, it can communicate with PC, and can analyze test data, including: voltage, internal resistance, connection resistance, capacity data table, histogram and battery change trend graph.
11. The historical data can be saved and managed dynamically according to the computer room/site name, battery pack name, battery model, type, manufacturer and installation date, etc., so as to compare and call the historical data at any time.
2. RBT-2000 product features
1. It can realize the connection resistance test to determine the battery's connectivity, which is completely online and easy to use.
2. The data processing is intelligent, and the instrument is an all-Chinese operation interface and analysis software, which is easier to use and convenient for maintenance personnel to analyze and process.
3. The standard internal resistance test method is adopted, and the voltage line, current line and data acquisition line are separated, effectively reducing the error of contact resistance
4. Failure alarm, timely detection of battery operation failure. When the detected internal resistance and voltage exceed the set upper limit or lower than the lower limit, the instrument will give a sound and text alarm.
5. The instrument has good repeatability and stability, and the stability of repeated tests is within 3%; the test signal is a large signal above 42A DC to ensure the test accuracy; the large signal test can effectively resist the ripple interference of the battery test environment;
6. The measurement parameters have high accuracy, strong anti-interference, high reliability and good repeatability. The battery charging and discharging waveform and switching noise basically do not affect the internal resistance accuracy.
7. Complete the test of voltage, internal resistance and connection resistance at one time, which truly reflects the test of all parameters of the complete battery pack; complete the test of key indicators at one time, effectively improving the test efficiency;
8. The test speed is fast, each unit test time is no more than 3 seconds, and it can store more than 10,000 test data.
9. The analysis software can automatically generate various test reports and reports: voltage, resistance, estimated capacity column chart, as well as the change trend chart and data table of the single battery.
10. The analysis software can also tailor some functions according to the actual needs of users.
11. Low power consumption, rechargeable battery power supply, the screen displays the power supply battery power, and can work continuously for 6 hours.
