Abstract
An electricity-storage system 110a is configured to be able to charge and discharge by connecting a plug to an electrical outlet 140a. Power discharged from the electricity-storage system 110a is monitored by a reverse-power monitoring device 100 and discharge from the electricity-storage system 110a is executed according to instruction from the reverse-power monitoring device 100, in order to avoid reverse power flow to an electrical grid 150.
Claims8
An electricity-storage system comprising:
- a first electricity-storage system including a first storage battery, a first communication device, and a first controller that transmits a signal via the first communication device when a power outage occurs;
- and
- a second electricity-storage system including a second storage battery, a second communication device in communication with the first communication device, a DC/AC inverter, and a second controller that stops discharge from the second storage battery to the DC/AC inverter and then to an AC power line network when the second communication device receives the signal from the first communication device, the AC power line network being connected to a load external to the second electricity-storage system,
- wherein the first storage battery is configured to supply electrical power to a load external to the first electricity-storage system, and the second storage battery is configured to supply electrical power to the load external to the second electricity-storage system, and
- a destination of the signal transmitted by the first controller via the first communication device is the second-electricity storage system.
2 more elements
An electricity-storage system operating method comprising:
- among a plurality of electricity-storage systems that each include a storage battery for supplying electrical power to an external load, and a DC/AC inverter, transmitting from a given electricity-storage system a signal to another electricity-storage system when a power outage occurs;
- and
- stopping discharge from the storage battery to the DC/AC inverter and then to an AC power line network of the other electricity-storage system that receives the signal, the AC power line network being connected to a load external to the other electricity-storage system,
- wherein a destination of the signal transmitted by the given electricity-storage system is the other electricity-storage system.
1 more element
An electricity-storage system comprising:
- a second transmitter that communicates via a first transmitter with a first electricity-storage system including a first storage battery and the first transmitter, the first transmitter transmitting a signal when a power outage occurs;
- a second storage battery;
- a DC/AC inverter;
- and
- a second controller that causes the second storage battery to stop discharge to the DC/AC inverter and then to an AC power line network upon the second transmitter receiving the signal from the first transmitter, the AC power line network being connected to a load external to the electricity-storage system,
- wherein the first storage battery is configured to supply electrical power to a load external to the first electricity-storage system, and the second storage battery is configured to supply electrical power to the load external to the electricity-storage system, and
- a destination of the signal transmitted by the first transmitter is the electricity storage system.
