Equipment features

UPSs are the most fundamental guarantee for equipment and network systems with increasingly higher informatization and automation. For both AC and DC UPS systems, batteries are extremely important by serving as emergency power supplies. Batteries are in floating charge at ordinary time and serve as the only energy suppliers for loads after AC power failure or any other emergencies. We know that some batteries failure earlier because of poor materials or structures, process defects, improper use, etc. For checks for the potential standby durations and actual capacities of battery packs and normal operation of power systems, battery packs should receive check discharge tests at regular intervals or whenever necessary as specified in the maintenance regulations of power systems so that the single batteries that have failed or tend to fail can be found and replaced early to make sure the corresponding battery packs can operate normally or their expected lives can be evaluated. We have successfully a line of extremely intelligent and accurate battery pack capacity testers (“tester”) that can serve as discharge loads and realize discharge with the set constant currents by means of continuous control over discharge currents. When the voltage of a battery pack or the voltage of a single battery of it is smaller than the set lower limit of voltage, or the set discharge duration or the set discharge capacity has reached during discharge, the tester will automatically stop discharge and record the real-time data of all valuable and continuous process. The voltage information of single batteries monitored by the tester is subject to wireless repeater access that is simple, secure and accurate. The tester supports setup and data queries on its friendly man-machine screens with help of menus; it saves the process data of discharge in its memory. The process data can be read and unloaded via a data interface and analyzed through special software on the host computer. Finally the desired curves and reports can be generated. The tester has comprehensive protection functions with help of audible and visual alarms and clear display on the screen.

Features when without monitoring function

The PTC ceramic resistor avoids the red hot phenomenon, making the whole discharge process safer; The internal controller includes two CPUs for the highest safety, stability and accuracy in testing so that a CPU can sound an alarm and shuts down the tester upon failure of the other CPU; Thanks to the all electric isolation technology, the discharge part can still operate normally in the case of strong electromagnetic interference or strong power interference; The tester has a 2G memory and supports a U disk up to 32G; The tester has functions such as check capacity test, discharge suspension, parallel load test and online compensated discharge for diversified occasions; The tester can upload discharge data to a U disk via its USB interface and import them to a host PC so that the data management software on the host PC can analyze the discharge and generate corresponding data reports, making data uploading easier; The tester is subject to intelligent single chip microcomputer ARM control and has a 7″touch screen LCD supporting menu operation and Chinese and English display; The tester supports automatic protection: When the set discharge duration or the set discharge capacity has reached, or the voltage of battery pack is smaller than the set minimum or the load wiring is abnormal, the tester will automatically stop discharge, sound an alarm and record the shutdown mode; The tester supports the setup of discharge stop conditions, including battery pack’s final voltage, discharge capacity and discharge duration to make the discharge test safe; The tester supports online compensated discharge and discharge tests for batteries in online service with help of external pincerlike current sensors, making discharge tests convenient. (This function is especially applicable to an occasion with only one emergency battery pack.)

Features when with a monitoring function

The PTC ceramic resistor avoids the red hot phenomenon, making the whole discharge process safer. The internal controller includes two CPUs for the highest safety, stability and accuracy in testing so that a CPU can sound an alarm and shuts down the tester upon failure of the other CPU. With the all electric isolation technology, the discharge part can still operate normally in the case of strong electromagnetic interference or strong power interference. The tester has a 2G memory and supports a U disk up to 32G. The tester has the following three wireless or wired communication modes: wireless or RS485 communication between a wireless acquisition box and the discharge main unit, which is for monitoring the voltage of each single battery in real time; wireless or RS485communication between the host PC’s software and a wireless monitoring module, which is for wireless monitoring for the voltages of single batteries while the tester is not connected; RS485 communication between the host PC’s software and the discharge tester with help of a communication line, which is for remote discharge control. The wireless acquisition box can monitor each battery, so it can monitor the whole discharge process of a battery pack. The tester has easy installation, debugging and maintenance and high stability and safety because its acquisition modules are isolated. The software on the host PC can analyze such recorded data as total voltage, discharge current and single batteries’ voltages, generate corresponding data reports, curves, graphs and reports indicating the battery pack performance directly and support queries and printing of these contents. The tester can upload discharge data to a U disk via its USB interface and import them to a host PC so that the data management software on the host PC can analyze the discharge and generate corresponding data reports, making data uploading easier. The tester is subject to intelligent single chip microcomputer ARM control and has a touch screen LCD supporting menu operation and Chinese and English display. The tester supports automatic protection: When the set discharge duration or the set discharge capacity has reached, or the battery pack’s voltage is smaller than the set minimum or the load wiring is abnormal, the tester will automatically stop discharge, sound an alarm and record the shutdown mode. The tester support the setup of testing or discharge termination conditions, including single battery voltage, battery pack’s voltage, discharge current and discharge duration. The tester can record the discharge information of each single battery during testing or discharge, such as total capacity, total voltage and total current of the battery pack and voltage changes of the single battery with the minimum voltage. The tester supports online compensated discharge and discharge tests for batteries in online service with help of external pincerlike current sensors, making discharge tests convenient. (This function is especially applicable to an occasion with only one emergency battery pack.)
