What are the advantages of lithium iron phosphate batteries as UPS power supplies? How to change UPS battery to lithium battery?
Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as the battery's positive electrode material. The key cathode materials for lithium-ion batteries are lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate and so on. Lithium cobalt oxide batteries are most of the battery cathode materials used in lithium batteries at this stage. Compared with traditional lead-acid batteries, lithium batteries have great advantages in terms of working standard voltage, specific energy, and cycle system service life.
Advantages of lithium iron phosphate battery as UPS power supply:
1. Security. The PO bond in the UPS crystallization of the lithium iron phosphate battery is stable and not easy to dissolve. Even under high temperature or overcharge standards, it will not collapse, become hot or produce strong oxidizing chemicals like lithium cobalt oxide batteries. Possess an excellent safety factor.
2. Application deadline. Compared with the lead-acid battery, UPS's cycle system service life is generally around 2000 times, while the UPS cycle system service life is 300 times of lead-acid battery. Applied under the same standard, the basic theoretical service life can reach 7 to 8 years. On the whole, the characteristic price comparison theoretically exceeds 4 times that of lead-acid batteries.
3. Working temperature. The operating temperature range of the battery pack is generally between -20°C and 60°C, and its heat resistance can achieve the highest value of electric heating between 350°C and 500°C.
Fourth, no memory. Often under the condition of incomplete filling, the volume of the rechargeable battery cell will quickly drop below the short-circuit capacity. This type of condition is called memory. Lithium iron phosphate battery is not prone to this kind of situation. No matter what kind of situation the rechargeable battery is in, it can be charged at any time, without having to charge the battery first and then the battery.
5. Net weight. A lithium iron phosphate battery rechargeable battery with the same volume has a volume of 2/3 of that of a lead-acid battery and a net weight of 1/3 of that of a lead-acid battery.
6. Ecological benefits. Lithium iron phosphate battery rechargeable batteries are generally considered to be environmentally friendly emerald green and environmentally friendly batteries without excessive heavy metals, non-ferrous metals, and zero pollution.
There are many advantages of lithium battery UPS power supply, because different types of lithium battery UPS power supplies have their own unique advantages. For example, the battery pack: the input can include power factor calibration (three-phase); N+X series sink for use (three-phase). In addition, the UPS, high-efficiency filtering and power supply circuit are fully compatible with on-board generators; the perfect combination with lithium iron phosphate batteries can reasonably reduce the load on the car and save the body's indoor space.
Preparatory work for replacing the UPS battery with lithium battery: After receiving the notice of the replacement of the rechargeable battery, the battery replacement implementation engineer went to the spot to carry out the preparatory work: to ensure the input switching power supply of the UPS server, the registration and inspection of the new and old batteries, and the smoke detectors of the fire-fighting facilities in the computer room The airtightness, prepare carbon dioxide fire extinguishers and other related work in advance. Before the UPS server, old battery packs, rechargeable battery monitors and other machinery and equipment are removed and replaced with lithium batteries, make a good record, especially the placement of rechargeable batteries in each layer, the wiring of the rechargeable battery monitor, and the identification and connection diagrams. . Ensure that the actual effect of the rechargeable battery after changing the battery is consistent with the reaction of the original battery.
1. Volume calculation After dismantling and replacing the UPS lithium battery, what must be done is to carry out the calculation of battery power. Calculate the volume of the lithium battery that must be replaced according to the volume of the original lead-acid battery. Although the volume of the lithium battery is smaller than that of the lead-acid battery under the same volume, there is no need to worry about using the same volume of the UPS lithium battery for replacement. excellent.
2. Lithium battery pack. Generally speaking, it is not easy to have a lithium battery with the same volume as the original UPS lead-acid battery. Generally speaking, the hands-on masters must operate separate small-volume lithium batteries in series and parallel by themselves, and install safety maintenance components to form a lithium battery pack. This type of lithium battery pack consists of an independent lithium battery, which is the best alternative to lead-acid batteries.
3. Inspection After the lithium battery pack is equipped, in order to better consider the safety, it is necessary to carry out several inspections on the UPS lithium battery pack. Carry out safety factor inspections for lithium batteries, and after replacement with lead-acid batteries, safety factor inspections must also be carried out. In order to better consider safety, it is always right to do more inspections.
4. Installation. After several tests, it was confirmed that the replacement of lead-acid batteries with lithium batteries was a success, and the overall home improvement could only be carried out after . Assemble the UPS battery again in an appropriate way to repair the consistency of the appearance, and then carry out an overall inspection. After the inspection is carried out, it can be counted as a real replacement.
5. Check whether everything is normal for the lithium battery pack and UPS power supply system. After the battery replacement work is in progress, use a digital multimeter to check the total working voltage of the lithium battery pack, and the connection status of the positive and negative and neutral points. After confirming that the rechargeable battery and UPS battery server are all working normally, turn off the rechargeable battery power switch, and the UPSups power system software resumes work.
