Lithium-ion batteries ZUBR LI-ION ES for industrial uninterruptible power supplies

Industrial UPS is a powerful uninterruptible power supply that is designed to provide high-quality electricity to industrial facilities. 1AK-GROUP produces li-ion batteries for industrial uninterruptible power supplies.

An uninterruptible power supply is used to reduce risks in the following situations (Figure 1):
— Limited available network power
— Frequency regulation, incl. deviation compensation
— Smoothing out consumption peaks
— Tariff maneuvering
— Buffer storage of electricity
— Autonomous power supply systems
— Emergency complete power outage

If one or more power supply problems occur, uninterruptible power supplies will help maintain or correctly shut down all machines and devices, save various data and prevent their loss.

Operating UPS in specific industrial environments requires a non-standard approach to designing batteries for such solutions. The requirements for batteries for office and industrial UPSs are different. In general, when using commercial UPSs, it is necessary to use lead-acid sealed maintenance-free batteries to ensure autonomous operation for from 10-30 minutes to several hours. In industry, in addition to sealed batteries, batteries with liquid electrolyte are used, which introduces a number of requirements for charging and placement of these batteries.

The last 10 years have seen the development of Li-Ion batteries for industrial uninterruptible power supplies. 1AK-GROUP offers standard and customized li-ion battery solutions for industrial UPSs. When designing custom solutions, 1AK-GROUP carries out the development of technical documentation for the battery, its 3D modeling, testing of the battery and installation in the customer’s equipment.

One example of standard solutions offered by 1AK-GROUP is the ZUBR LI-ION ES battery, which has the chemical formula LiFePO4.

It is intended for:
— ensuring uninterrupted power supply to industrial electrical installations for more than 60 minutes
— for use in energy storage systems, including those with renewable energy sources.

ES in the name stands for Energy Storage, these modules are installed in standard telecommunications equipment cabinets.

ZUBR LI-ION ES batteries have an indication screen, a fuse and a set of switching outputs for interaction with other elements of the system.

ZUBR LI-ION ES batteries are equipped with a charge monitoring and management system (BMS). BMS monitors and balances battery cells, ensures battery shutdown according to built-in protections: overcharge, deep discharge, overcurrent or short circuit inside the battery.

Replacing lead-acid batteries with lithium-ion batteries in industrial UPSs is associated with the operating conditions of the equipment, which include:
— increased air temperature, in such conditions lead-acid batteries quickly lose capacity and their service life decreases
— the need to reduce the dimensions of the case while maintaining and/or increasing the voltage and capacity of the battery
— greater permissible discharge depth, which allows you to use more power with a smaller or comparable battery capacity
— high discharge currents, which makes it possible to reserve large load powers with relatively compact batteries with a lower capacity
— longer life, both in cycles and in years of battery operation in buffer mode

ZUBR LI-ION ES batteries are used for industrial UPS in such sectors of the economy as telecommunications, energy facilities, production sites, backup and power systems for critical control units, equipment that does not allow interruption of technical processes.

ZUBR LI-ION ES batteries comply with the requirements and standards: GOST 12.2.007.12-88, GOST R IEC 61960-2007.
