Advantages Of Using Lithium Battery UPS As A Power Supply Management System

Lithium battery UPS is a new type of lithium battery energy storage power supply. Compared with traditional UPS lead-acid batteries, it has the advantages of environmental protection, safety, long service life, high temperature resistance, and no memory effect. So, what are the advantages of lithium battery UPS management system?

Advantages of using lithium battery UPS as a power supply management system

Today, for UPS battery power supply systems, the initial capital expenditure of lithium-ion batteries is only 1.4 times that of lead-acid batteries, but the total cost of ownership (TCO) of lithium-ion batteries for 10 years can be saved by 10%-30%. The advantages are as follows:

① Light weight

Lithium batteries are about one-third lighter than lead-acid batteries. This saves data center construction costs because there is no need to reinforce the floor to bear more weight. It also saves transportation costs because more lithium-ion batteries can be transported at the same cost compared to lead-acid UPS batteries.

② Long life

The cycle life of lead-acid batteries is about 300 times. For lithium iron phosphate batteries, the capacity of the monomer is still greater than 80% after 2,000 cycles at 1C charge and discharge at room temperature, and the 3C cycle life reaches more than 800 times.

③ Fast charging

Lithium battery UPS can charge and discharge quickly at a high current of 2C. The battery can be fully charged within 40 minutes at 1.5C under a dedicated charger, and the starting current can reach 2C, while lead-acid batteries do not have this performance now.

④ Higher energy density

Lithium battery UPS has higher energy density (Wh/kg, or watt-hour per kilogram) and power density. The energy density is 3 to 4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-hydrogen batteries.

⑤ High temperature resistance

Lithium battery packs can operate at a temperature of 86°F (30°C), which is nearly 10°C higher than lead-acid batteries. The thermal peak of lithium iron phosphate battery UPS can reach 350~500℃, and the operating temperature range is wide (-20~+75℃).

⑥ Reduce maintenance and reduce costs

Lithium batteries are equipped with a built-in battery management system (BMS), which can provide monitoring and maintenance functions such as automatic status, fault monitoring, battery balancing, power optimization and external communication. Lithium battery UPS can reduce labor and maintenance costs and significantly reduce the risk of battery pack failure.

⑦ Environmental protection and pollution-free

Lithium iron phosphate materials do not contain any heavy metals and rare metals, are non-toxic, and are pollution-free in both production and use. They comply with European RoHS regulations and are green and environmentally friendly batteries. However, there is a large amount of lead in lead-acid batteries. If they are not properly handled after being discarded, they will still cause secondary pollution to the environment.

⑧ No memory effect

Lithium iron phosphate battery packs can be charged and used at any time regardless of their state, without having to fully discharge them before charging.

Future predictions and prospects for UPS lithium battery management systems

For large data centers, the amount of savings from using UPS lithium battery systems will be huge, so lithium battery power supply systems will gradually increase in the corporate sector. Lithium-ion chemistry is also continuing to advance. New solutions and technologies will emerge over time, and the price of lithium batteries will fall further.

It is inevitable that lithium batteries will replace lead-acid batteries. From a long-term perspective, lithium battery UPS can save 10% or more. At present, lithium batteries have begun to replace lead-acid batteries in UPS abroad. More companies have begun to accept lithium batteries replacing lead-acid batteries. In some countries (such as South Korea), the process of lithium batteries replacing lead-acid batteries is very fast, and lithium batteries have accounted for as much as 30%. There are even all-lithium battery UPS systems like Shinhan Bank. It will be a trend to use lithium battery UPS as a power management system, and the advantages of lithium batteries as energy storage UPS power supply will increase.
