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 3×109 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.
