Battery Management and Auxiliary Power Supply Options for E-Meters


Smart electric meters are required to maintain normal operation for a short period of time after the electric grid fails. This reference design details methods by which designers can meet this requirement when using an advanced: smart meter MCU. Designers can use this design to evaluate options for battery management and auxiliary power supplies quickly and easily.

  • Two types of power sources for the auxiliary supply of the host MCU: independent regulator with super-cap back-up and (2) AAA batteries Separate power supply for Real-time Clock Automatic time capture of external events for tamper detection Automated or manual switching of power supply Automated power supply monitoring
  • Electricity meter
  • Power quality analyzer
