During power outages, batteries play an important role as backup power sources in DC systems, and many important equipment must rely on batteries for maintenance and operation. However, before the expected lifespan of the battery is reached, its capacity will experience a significant decrease due to various reasons. Therefore, the capacity of the battery must be checked regularly to avoid causing you heavy economic losses in the event of a power outage due to an electrical accident.
In order to verify the standby time and actual capacity of the battery pack and ensure the normal operation of the system, it is generally necessary to conduct a verification discharge test on the battery pack once a year. The reliable method to determine whether the battery capacity meets the requirements is to conduct a deep constant current discharge test. Traditional battery discharge testing generally uses bulky resistance boxes, requiring manual adjustment of discharge current, low control accuracy, complex work, and high labor intensity.
The RS-232 of this machine can upload and transmit data to the computer, and when combined with the LX-11 intelligent detection system for data analysis, it can store data for a long time and compare it with historical data. The following results can be obtained:

Wiring instructions:
1: The positive and negative terminals of the battery input should be connected to the positive and negative terminals of the discharge meter respectively.
2: The positive and negative electrodes of the single cell voltage collection should be connected to the positive and negative electrodes of the battery, respectively.
3: When wiring, check that the circuit breaker is in the disconnected position.
4: The impedance selection switch of this device can be designed according to user requirements, and can be used to form two combinations of discharge meters: 48V, 110V, and 220V.
5: After the wiring is completed, carefully check whether the wiring is correct, and pay attention to whether the positive and negative terminals of the battery input terminal and the single cell voltage acquisition input terminal are correct and should not be connected in reverse.
