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

Technological advances

Problems

Power outages
Low charge efficiency of lead-acid batteries - 65-85%
High self-discharge rate (up to 15% per month)

Solutions

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)

Expense trimming

Problems

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

Solutions

Increasing LIB replacement period by 3-4 times
Reduced floor space requirement
Saving on maintenance and staff

Optimization of the operation process

Problems

Charging of acid batteries takes 8-10 hours
Inefficient monitoring of battery condition during operation

Solutions

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
