FAQ
Q: What is the purpose of battery discharge testing?
A: Battery discharge testing is used to verify the actual capacity of battery packs, identify weak or degraded batteries, and assess the overall health status of the battery system. According to DL/T 724-2000 standard, new battery packs should undergo a capacity test after installation, and operating battery packs should be tested every 1-3 years to ensure they can provide sufficient backup power during power outages.
Q: What is the advantage of 10-300V wide voltage design?
A: Traditional battery discharge testers are designed for specific voltage levels (48V, 110V or 220V), requiring multiple instruments for different systems. GDBD-(10-300V)50A's 10-300V wide voltage range covers all mainstream DC power systems from 48V to 220V, allowing one instrument to perform all battery discharge tests, significantly reducing equipment purchase and maintenance costs.
Q: How does the constant current control work?
A: The instrument adopts advanced closed-loop constant current control technology. It continuously monitors the discharge current in real time and automatically adjusts the load resistance to maintain the set current value, even as the battery voltage drops during discharge. This ensures that the discharge rate remains constant throughout the test, providing accurate and reliable capacity measurement results.
Q: Is it safe to discharge batteries with this instrument?
A: Yes. The instrument is equipped with an 8-level comprehensive safety protection system that protects both the battery and the instrument from various abnormal conditions. The nickel-chromium alloy load has no red heat phenomenon and no open flame, eliminating fire hazards. The reverse polarity protection prevents damage caused by incorrect battery connection.
