Li-ion battery-powered uninterruptible power supplies (UPS)
The main function of UPS is to provide an accident-free shutdown of the equipment in case of a power failure or emergency power supply during a start of a backup generator. To provide the same system characteristics with a short backup time, LIB's required capacity can be half as big as LAB's.
Provide an accident-free shutdown
Problems and solutions
Low charge efficiency of lead-acid batteries - 65-85%
High self-discharge rate (up to 15% per month)
Instant switch to battery power when the mains voltage disappears
High efficiency of LIB - 93-95%
Low self-discharge rate (on average, 3% per month)
Accelerated LAB degradation --> frequent battery replacement (on average, once every 3 years)
Low energy density in LAB --> high mass and large dimensions --> need for work areas
LAB require maintenance and staff
Increasing LIB replacement period by 3-4 times
Reduced floor space requirement
Saving on maintenance and staff
Charging of acid batteries takes 8-10 hours
Inefficient monitoring of battery condition during operation
Accelerated charging of LIB is 2-3 hours
A built-in control system (BMS) that monitors the status of each element's parameters and can transmit results to the control room
for switching from LAB to LIB
Current parameters of working with LAB
The calculation is based on average market prices for LAB and LIB, established by LLC RENERA, in the course research in 2020 year, based on average calculated indicators maintenance of batteries and charging room in 2020 according to experience of partners LLC RENERA, and also based on the average annual rate inflation and euro rate in for October 2020 year.
The calculation is for informational purposes only and may differ depending on from battery parameters and conditions of their operation.
