Energy saving systemfor home appliances and home network devices- Part 1 : Architecture and requirements Korea Electronics Technology Institute (KETI) Kwang-Soon Choi
Proposals Energy saving system (ESS) for home appliances and home network devices • Part 1 - Architecture and requirements • Part 2 - …… • Part 3 - …… Technical specifications . . . . . . .
Scope & Purpose • Scope • Architecture of Energy Saving System (ESS) • Conceptual model of ESS • Basic architecture of ESS • Requirements • ESS client • ESS server • ESS server-compatible home appliance • Purpose • In order to provide consumers • With energy monitoring functions to make them aware how much electric energy they are consuming • And with Intelligent energy saving functions to cut off passive and active standby power that consumers are not aware of
Conceptual Model (1) Electric Power Appliance #1 ESS Client #1 Appliance #2 ESS Client #2 . . . . . . . . . . . . . . Appliance #n ESS Client #n No new wire networking ESS Client #n+1 ESS Server Energy Saving System (ESS) • 1. Mainly composed of one ESS server and one or more ESS clients • 2. Two possible models : ESS model 1 (ESS server-free) and 2
ESS model 1 Electric Power Appliance #1 ESS Client #1 ESS model 1 (ESS server-free model) Appliance #2 ESS Client #2 . . . . . . . . . . . . . . Appliance #n ESS Client #n Self power consumption < 0.2 W Energy Saving System (ESS) • Functions of ESS model 1 • (1) Detection of passive standby power mode of appliances • (2) Cut-off of passive standby power automatically
ESS model 2 (1) Electric Power Appliance #1 ESS Client #1 Self power consumption < 0.5 W Appliance #2 ESS Client #2 . . . . . . . . . . . . . . Appliance #n ESS Client #n No new wire networking ESS Client #n+1 ESS Server Energy Saving System (ESS) • Functions of ESS model 2 • (1) Functions of ESS model 1 • (2) Detection of active standby power mode of appliances • (3) Saving and restoration of context (network configurations, etc.) of appliances • (4) Cut-off of active standby power of home network devices • (except home gateway, home server, home security, etc.) • (5) Monitoring of energy consumption status (optional function)
ESS model 2 (2) • Functions of ESS model 2 = Functions of ESS model 1 + additional functions • Addition functions of ESS model 2 • Detection of active standby power mode of appliances • Cut-off of active standby power • Monitoring of energy consumption status (optional function) • Feasible types • a stand-alone system • functional modules that can be implemented into legacy home gateway (or home server) • Requirements related to • Functions of appliances, ESS clients and ESS server • Saving of context of an appliance before cutting off its supply of electric power • Restoration of context of an appliance after supplying electric power • Simple communication protocol for power-monitoring and power-control between ESS clients and server
Functions and Classification (1) • Appliance • Supporting devices • Legacy home appliances and legacy home network devices • ESS clients cut off only passive standby power of legacy devices. • New home network devices which meet this specification • ESS server and clients cut off both of passive and active standby power. • ESS Clients • Functions • Function 1 : Cut off the supply of electric power by itself or an ESS server • Function 2 : Detect passive standby power mode of appliances connected to it • Function 3 : Detect active standby power mode of appliances connected to it • Function 4 : Calculate (or measure) the amount of consumed power (or electric current and voltage) and send result to ESS server • Classes • Class 1 : ESS clients which meet Function 1 and 2 above (for ESS model 1) • Class 2 : ESS clients which meet Function 1, 2 and 3 above (for ESS model 2) • Class 3 : ESS clients which meet Function 1, 2, 3 and 4 above (for ESS model 2) • Feasible Types • Type 1 : outlet type (for legacy devices) • Type 2 : adaptor type (for legacy devices) • Type 3 : new devices with a built-in ESS client
Functions and Classification (2) 3) ESS server • Functions • Communication Function • Be notified the active standby power mode of appliances • Send control commands to ESS clients in order to cut off the supply of electric power • Send query commands to ESS clients in order to monitor the power consumption status of appliances • Monitoring function • Build DB by using data from ESS clients • Query functions (with device name or ESS client ID) • Display total amount of power consumed during a specific period • Energy saving function • Cut off active standby power consumed by home network devices • User-configurable interface and alarm service • Feasible Types • Type 1 : stand-alone type (no connection to home server or home gateway) • Type 2 : stand-alone type, but it is interoperable with home server or home gateway • Type 3 : home server or home gateway type (can be implemented as additional functions of home gateway (or home server))
Expected Effects Standby power consumption of a middle class household in Korea (2003) Passive Standby power When applying ESS Active Standby power
