The British Ministry of Defence uses lithium-ion batteries as an energy source for individual combat systems, and the bag-shaped lithium-ion batteries developed by it have ultra-high specific energy. In addition, most of the future soldier combat systems developed by the military of various countries around the world currently use lithium-ion batteries as the power source. For example, the US "Land Warrior" individual combat system and the German "Future Soldier" systems use lithium-ion batteries. The following Lithium Iron Phosphate Battery Rack Manufacturer will introduce to you.

1. The "new energy favorite" of offshore equipment
The lithium ion battery is used as the power source of the submarine, which can greatly improve the speed, range and survivability of the submarine, and reduce the maintenance cost of the submarine. In recent years, multinational navies have applied lithium-ion batteries to miniature submarines, while developing lithium-ion batteries suitable for medium and long-range submarines. For example, the French Scorpion-class submarine is equipped with a new generation of lithium-ion batteries that can withstand high current charging, which greatly reduces the charging time of the submarine and doubles the underwater life.
Lithium-ion batteries used in torpedoes can greatly reduce the volume and weight of the power part of the torpedo, and can be used repeatedly in training to meet the training needs of the army. At present, the French Navy has successfully developed torpedoes with lithium-ion batteries, operating speeds of more than 50 knots (92.5 km / h), and endurance times of more than one hour. Both reliability and safety meet operational performance requirements. In addition, foreign forces are exploring the use of lithium-ion batteries as power systems for surface ships.

2. "Third Generation Power Source" for Aerospace Vehicles
Lithium-ion batteries are known as the third generation of aerospace power, and have been gradually applied to various types of aerospace equipment in recent years. For example, the Lithium-Ion Battery Energy Storage System has been used as a power source for the International Space Station. In the field of military aviation, lithium-ion batteries are mainly used in small, miniature UAVs. The "Longyan" unmanned reconnaissance aircraft used by the U.S. military in the Afghanistan war, using lithium-ion batteries as a power source, has been tested in combat. However, in general, the application of lithium-ion batteries in this field is still in its infancy, and the main constraints are insufficient miniaturization and insufficient power.

Life Of Rack UPS Lithium Battery

Rack UPS is a type of lithium battery UPS. What is the service life of the internally equipped lithium battery? Since it is a lithium battery product, its life is generally "2000 times".

How long does a rack UPS lithium battery last? In fact, the service life of Rack Mount Li-Ion Battery System is generally not calculated by year and month, but by the number of cycles. Of course, the number of cycles is not just the number of charge and discharge but a cycle of charge and discharge.

Rack Mount Li-Ion Battery System

Rack Mount Li-Ion Battery System

This life of 2,000 times also means that the rack UPS lithium battery has 2000 charge and discharge cycles. However, a charging cycle does not mean that the full charge of the lithium battery must be used before the next charging. Instead, when the lithium battery is used for a period of time, the battery is charged when it is less than half of its charge, and it is fully charged until the next day when the remaining power is used and then fully charged, it can be counted as a charging cycle.

However, the life of the 2000 charging cycles is not absolute, because if you spend more money, you can customize a rack UPS power supply with a longer cycle life.

After talking about this service life, Li-Ion Battery Energy Storage System Supplier also wants to tell you some ways to extend the service life of rack UPS lithium batteries. After all, after the lithium battery is manufactured, its capacity is limited, but during use, the correct use method and daily maintenance will help extend the life of the lithium battery of the rack UPS.

So how to extend the life of the rack UPS lithium battery? The following ESS All-In-One suppliers will come to tell you.

1. Use environment
The environment in which a rack UPS is used is also very important. It requires less dust, no corrosive air, and should not be exposed to direct sunlight. It must also have a good lightning protection effect. The temperature in the equipment room should also be controlled within a certain range, and the floor should be installed with an antistatic floor.

2. Access load
The most reasonable load range is 30% -60%. Full and overload use will affect the life of the UPS. Maintenance should be performed at least once a year.

3. Charge and discharge
Regular charging and discharging of a lithium battery can better extend its service life. Generally, it is completely discharged every 2-3 months. The specific time for discharging needs to be determined according to the capacity and load of the lithium battery. After a full load discharge is completed, recharge according to the instructions.

4. Correct power on / off sequence
The correct start-up and shutdown sequence should be to first turn on the UPS to supply power to it, and then turn on the various loads. This can avoid the damage caused by the instantaneous current impact on the UPS during the startup. The sequence is exactly the opposite during shutdown.

When using the rack UPS lithium battery, there are still many places that need attention. The correct method of use and daily maintenance can effectively extend the life of the lithium battery.
