Abstract

An energy management system controlling energy flowing into or out of a battery is provided. The energy management system includes a data receiving unit receiving load data and energy data; a total load amount calculating unit calculating the total amount of power consumption by using the received load data; an energy generation amount calculating unit calculating the total amount of power generation by using the received energy data; a comparator comparing the calculated total amount of the power consumption with the calculated total amount of the power generation; and a switch connecting the battery to a power supply according to a comparison result.

First claim

What is claimed is:

1. An energy management system controlling energy flowing into or out of a battery, the energy management system comprising:
a data receiving unit configured to receive load data and energy data;
a total load amount calculating unit configured to calculate a total amount of power consumption by using the received load data;
an energy generation amount calculating unit configured to calculate a total amount of power generation by using the received energy data;
a comparator configured to compare the calculated total amount of power consumption with the calculated total amount of power generation and generate a comparison result;
a switch configured to regulate power flowing into and out of the battery; and
a energy management unit configured to:
receive the comparison result;
generate a switch OFF signal for blocking power from flowing into and out of the battery or a switch ON signal for enabling power to flow into and out of the battery, the switch OFF signal generated when the total amount of power generation is larger than the total amount of power consumption and the switch ON signal generated when the total amount of power generation is smaller than the total amount of power consumption; and
transmit the generated switch OFF signal or switch ON signal to the switch.

2. The energy management system according to claim 1 , wherein the load data is received from a load or a main register.

3. The energy management system according to claim 2 , wherein the energy data comprises a time-zone dependent usage amount of power generated by a new renewable energy generation system.

4. The energy management system according to claim 3 , wherein the new renewable energy generation system comprises at least a photovoltaic system or a wind power generation system.

5. The energy management system according to claim 2 , wherein the load data is received from a main register.

6. The energy management system according to claim 1 , wherein:
the data receiving unit receives the load data and energy data without user input; and
the total load amount calculating unit autonomously calculates the total amount of power consumption and the energy generation amount calculating unit autonomously calculates the total amount of power generation.

7. An energy management method of an energy management system controlling energy flowing into or out of a battery, the energy management method comprising:
receiving load data and energy data;
calculating a total amount of power consumption by using the received load data;
calculating a total amount of power generation by using the received energy data;
comparing the calculated total amount of power consumption with the calculated total amount of power generation;
generating a switch OFF signal for blocking power from flowing into and out of the battery or a switch ON signal for enabling power to flow into and out of the battery, the switch OFF signal generated when the total amount of power generation is larger than the total amount of power consumption and the switch ON signal generated when the total amount of power generation is smaller than the total amount of power consumption; and
transmitting the generated switch OFF signal or switch ON signal to a switch.

8. The energy management method according to claim 7 , wherein the load data is received from a load or a main register.

9. The energy management method according to claim 8 , wherein the energy data comprises a time-zone dependent usage amount of power generated by a new renewable energy generation system.

10. The energy management system according to claim 9 , wherein the new renewable energy generation system comprises at least a photovoltaic system or a wind power generation system.

11. The energy management method according to claim 8 , wherein the load data is received from a main register.

12. The energy management method according to claim 7 , wherein:
the load data and energy data are received without user input; and
the total amount of power consumption is calculated autonomously and the total amount of power generation is calculated autonomously.
