Complete Guide To Server Rack Battery

Server rack batteries are becoming increasingly popular in the home solar market, so let’s talk about rack mounted batteries today.

What is server rack battery?

As the name suggests, server rack batteries are specially installed in server racks, also known as rack-mounted batteries, which were once used as UPS in data centers. Server rack batteries are usually in a flat shape, use the exact specifications as the server chassis, and are installed in a designated standard server rack.

Advantages of A server rack battery

Rack mounted batteries use lithium iron phosphate batteries, also called rack mount lithium batteries or rack mount lifepo4 batteries, which have the following advantages:

How does rack mount battery work?

Server rack lifepo4 battery usually consists of a battery management system (BMS), a square battery, an operation panel, a plastic bracket, and a cover. The communication protocol port includes RS485, RS232, CAN protocol, etc. It can support the coexistence of unlimited units, which helps the parallel connection of multiple batteries to expand capacity and power. Rack-mounted battery with LCD; you can read the system’s operating status and control it anytime. 

48v Server Rack Battery Configuration

The rack battery is based on a lithium iron phosphate battery and lithium battery system. The built-in BMS system and high-performance balancing technology improve the product’s overall safety and service life. It is not only flexible in configuration but also high in reliability.

Multiple rack-mounted lithium batteries are placed in the rack, called cabinet-type energy storage batteries. The rear end of each battery is connected to the main control box on the top to control the performance of each battery. For example, the rack-mounted UPS backup battery can maintain the status of each battery through the main control box on each battery.

The intelligent BMS protection board built into the rack battery has multiple protection functions. Such as overcharge, over-discharge, overvoltage, overcurrent, overtemperature protection, and short circuit and leakage protection.

Application of server rack lithium battery

The server rack lithium battery adopts grade A lithium iron phosphate cells with a compact design. Due to its unique structure, it is suitable for small industrial sites, equipment rooms, data centres, telecommunications equipment, UPS backup power systems, communication base stations, commercial office buildings, Single-family houses, energy storage systems, etc.

Communication Base Station Energy Storage

The server rack battery adopts an embedded modular design, and the power and capacity of the battery can be flexibly configured to meet the backup power requirements of communication base stations fully. It can be used as an energy storage device for communication base stations with equipment rooms.

As a backup power source for communication base stations, rack batteries have the following advantages:

⑴ Communication base stations are primarily built in remote areas, and routine maintenance and battery replacement are complex and costly. The grade A lithium iron phosphate battery used in the rack battery has high safety and long life and requires no maintenance.   

⑵ The geographical climate conditions of communication base stations are complex and widely distributed. The lifepo4 battery has a wide range of temperature resistance. The self-heating function can be charged and discharged usually even in a low-temperature environment, meeting the application requirements under complex climate conditions.

⑶ When the communication base station is in an off-grid state, it can be operated with new energy, such as wind and light. Lithium iron phosphate batteries have the advantages of fast charging and discharging, which can quickly store the power generated by new energy sources such as wind and light, and output high-quality and stable electric energy.

Rack mount lead acid battery vs rack mount lithium battery

Server rack lifepo4 batteries are more environmentally friendly as a new energy source, but rack lead-acid batteries are still on the market. What’s the difference between the two?

⑴ Safety

The rack mounted lifepo4 battery is a green new energy source, stable and more environmentally friendly.

Rack-mounted lead-acid batteries have the potential to leak toxic gases.

⑵ Performance

Rack mount lifepo4 batteries have been proven to have higher energy density and provide a more stable current.

Rack-mount lead-acid batteries may also have a relatively high energy density, but the current supply is not constant and decreases as the battery drains.

⑶ Stability

When placing any rack mount lifepo4 battery in a rack server, it is vital to consider the stability of the battery in question, and lithium batteries are a more stable choice.

Rackmount lead-acid batteries are much less stable due to their liquid acid composition.

⑷ Charge and Discharge Cycle

The charge-discharge cycle of the rack mounted lithium battery is better, the charge can reach 100%, and the discharge can get 0%, which has little effect on the battery.

Rackmount lead-acid batteries should only be charged to 80% and discharged to 20% to avoid adverse effects on the battery itself.

The cycle life of lithium batteries can be as high as 7000 times, much higher than that of lead-acid batteries.

⑸ Weight

Under the same capacity, lithium batteries are lighter than lead-acid batteries.
