The difference between lithium battery UPS and lead-acid battery UPS

The difference between lithium battery UPS and lead-acid battery UPS

Before the UPS delivery operation, make sure to UPS and related system software to carry out the specialized testing, include: office environment, the main type in working voltage, double circuit power supply type working voltage, output voltage, output current, output frequency, rechargeable batteries work voltage, charge/charge and discharge electricity flow, UPS battery temperature examination.Details are as follows:

1. Check the main parameters of UPS lithium battery and battery input and output: I/O working voltage, current flow, frequency, output power, power factor, working voltage harmonic distortion degree;

2. Maintenance check of over input and under input working voltage: Simulate the situation when the working voltage exceeds the allowable transition range, and check whether the UPS system software can be automatically converted into a rechargeable battery power supply system;The simulation simulated the working voltage recovery to verify whether the lithium battery UPS and UPS battery system software can be fully automatic from the rechargeable battery inverter power to all normal operation;

3. Monitor characteristics inspection, and check the status of standard communication ports such as RS232 or RS485/422, IP/USB of UPS rechargeable battery system software;System software all normal work/rechargeable battery inverter power supply/double circuit power supply power supply system, load, battery discharge low working voltage, common faults, output power control module.

4. UPS lithium battery and battery belt loading inspection: make sure that the UPS machine and equipment operate normally, whether the load electrode connection line is properly installed, and whether the testing equipment and measuring instrument are properly connected;

5. Appearance inspection of lithium battery and UPS battery: the appearance of rechargeable battery and battery cabinet is intact, the cable connection is firm, the terminal bar is firmly tightened, and there is no liquid leakage mark inside the rechargeable battery and battery cabinet;

6. Check the natural environment and appearance, the cleaning situation of the interior space, temperature, internal dust and cleanliness level of the lithium battery UPS and UPS battery machine and equipment backup power system software;

7. Check the application time of lithium battery;Check whether the rechargeable battery is leaking or leaking;Check whether the electrode connection of the rechargeable battery is loose.

What are the common inspection methods for UPS batteries and lithium batteries?

The internal resistance characteristic tester, battery charging test, working voltage resistance test, the case is not the bag leakage and so on are all standard testing instruments.

What are the specifications of UPS lithium battery and battery engineering acceptance?

The key is the multi-functional detection, such as voltage failure to the charging and discharging of the rechargeable battery, voltage recovery to the battery charging, and switching to the double-circuit power supply operation, which usually includes:

1. The output working voltage is stable and meets the requirements

2. The rated output power is sufficient for embedment

3. The battery power is in accordance with the regulations

4. Everything is normal during the engine change
