Abstract :
The high performance backup power supply system is a powerful and clean backup power supply system suitable for the next-generation telecommunication systems. It uses nickel-metal hydride batteries, which have higher energy density than the lead-acid batteries used in conventional power supply systems. Compared to conventional systems, it offers longer power supply backup periods for the same installation space, or less space is needed for the same backup time. Also, the elimination of lead makes it environmentally friendly.
