Many critical devices must rely on batteries to maintain operation. However, before the end of battery life, its capacity may significantly decrease due to various reasons. Therefore, battery capacity must be regularly tested to avoid severe economic losses during power outages. To verify the backup time and actual capacity of the battery pack and ensure normal system operation, a verification discharge test is generally performed annually on the battery pack. The most reliable method to determine whether battery capacity meets requirements is to conduct a deep constant current discharge test. Traditional battery discharge tests typically use bulky resistor banks, requiring manual adjustment of discharge current, with low control accuracy, complex operation, and high labor intensity. The battery load tester and intelligent battery load tester series battery discharge monitor is a new type of battery testing equipment designed specifically for power, telecommunications, aviation emergency power, and computer networks. This equipment performs constant current discharge on batteries, tests and verifies battery capacity, monitors, records, and stores circuit parameters such as discharge voltage, discharge current, discharge time, and discharge curves. This instrument has RS-232 and RS-485 communication interfaces, battery pack voltage and current signals, and a discharge stop interface, making it easy to connect to a computer to print various record charts, curves, and perform traditional and network control of battery discharge. |
