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

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)

  • 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

  • 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
