Power supply control system, power supply control device and method

A power supply control device comprising:

• a battery;
• a communication unit;
• and
• a startup unit for receiving a wireless startup signal transmitted from an external controller, and supplying power from the battery to the communication unit while receiving the wireless startup signal;
• and
• the communication unit for, while being supplied with power from the battery, receiving a monitoring control instruction from the external controller, acquiring a monitoring control result for the battery, and transmitting the monitoring control result to the external controller as needed in response to the monitoring control instruction,
• wherein the startup unit includes
• a wireless signal detection unit for detecting a signal intensity of a received wireless signal, and
• a startup signal determination unit for determining a data pattern of a received wireless signal,
• wherein the startup signal determination unit is supplied with power from the battery while the wireless signal detection unit detects a wireless startup signal with a predetermined signal intensity or more, and
• the communication unit is supplied with power from the battery while the startup signal determination unit determines that the data pattern of a wireless signal matches with a predetermined data pattern.

A power supply control method in a power supply control system,

• wherein the power supply control system includes
• one or more power supply control devices supplied with power from a battery, and a controller for wirelessly communicating signals with the power supply control devices, the method comprising:
• receiving, by each of the power supply control devices, a wireless startup signal transmitted from the controller,
• supplying power from the battery to a communication unit while receiving the wireless startup signal, and
• while being supplied with power from the battery, receiving, by the communication unit, a monitoring control instruction from the controller, acquiring a monitoring control result for the battery, and transmitting a monitoring control result to the controller as needed in response to the monitoring control instruction,
• detecting a signal intensity of the received wireless startup signal, and
• determining, by a startup signal determination unit, a data pattern of the received wireless startup signal,
• wherein the startup signal determination unit is supplied with power from the battery while the wireless signal detection unit detects a wireless startup signal with a predetermined signal intensity or more, and
• wherein the communication unit is supplied with power from the battery while the startup signal determination unit determines that the data pattern of the received wireless startup signal matches with a predetermined data pattern.
