How to check and accept the lithium battery UPS and UPS battery? What are the common detection methods for UPS battery and lithium battery UPS? When you buy the UPS power battery, you need to check the inspection. This requires professional personnel and industry basic knowledge to check. . Today, Cuneng Electric Xiaobian will share an article about how to check the acceptance of lithium battery UPS and UPS battery. I hope everyone likes it.
How to check and accept lithium battery UPS and UPS battery?
In order to ensure that the performance of the lithium battery UPS and battery UPS system meets the requirements of normal operation, the UPS and its related systems must be systematically tested before the UPS is put into operation, including: working environment, main input voltage, bypass input. Voltage, output voltage, output current, output frequency, battery voltage, charge/discharge current, UPS battery temperature, etc. details as follows:
1. UPS lithium battery and battery input and output parameter check: input and output voltage, current, frequency, power, power factor, voltage harmonic distortion;
2. Input over and under voltage protection check: The analog input voltage exceeds the allowable range of change, detect whether the UPS system can automatically switch to battery power supply; the analog input voltage returns to the normal range state, and the lithium battery UPS and UPS battery system can be automatically detected. The battery inverter is switched to the normal working mode;
3, monitoring performance testing, check the UPS battery system RS232 or RS485/422, IP / USB and other standard communication interface work; system normal work / battery inverter / bypass power supply, overload, battery discharge voltage low, mains failure, power Module status.
4. UPS lithium battery and battery with full load test check: Make sure that the UPS equipment is running normally, the load connection line is installed correctly, and whether the test equipment and the test instrument are connected correctly;
5. Appearance inspection of lithium battery and UPS battery: The appearance of the battery and the battery cabinet is intact, the cable connection is firm, the terminal is fastened firmly, and there is no leakage trace inside the battery and the battery cabinet;
6, environmental and visual inspection, lithium battery UPS and UPS battery equipment backup power system space cleaning conditions, temperature, internal dust and cleanliness;
7. Check the lithium battery pack usage time; check if the battery has liquid and liquid leakage; check if the battery cable is loose.
What are the common detection methods for UPS batteries and lithium batteries?
Internal resistance tester, charge and discharge test, voltage resistance test, whether the casing is leaking or not, etc. are all standard test equipment.
What are the standards for UPS lithium battery and battery acceptance?
Mainly functional tests, such as power outages to battery discharges, utility power returning to normal, charging batteries, and bypassing operations, generally include:
1, the output voltage is stable and meets the requirements
2, the rated load power is enough to reserve
3, battery capacity meets the requirements
4, the head conversion works normally
The above are some methods and techniques for the acceptance test of lithium battery UPS and UPS battery. After receiving the goods, you should remember to check according to the above methods. It is best to buy a UPS battery with guaranteed quality, and you can avoid some maintenance costs later. .
