Grid Power Energy System for IoT Applications.

A new type of nickel metal hydride batteries have been developed for backup power supply system. The prepared grid power energy system has high capacity for backup use and also provides a backup power time to the systems up to 13 hours at 21 °C under 210-VA output power. The average power of the system increases up to 16 W. The grid power source stabilized at 3x109 cycles with the increase of frequency. The external energy source of the grid power system increases up to 4 J. Thus it can be used as a promising outdoor power supply for electronic devices. [ABSTRACT FROM AUTHOR]
