Storage e.g. lithium ion accumulator, for storing electrical power in e.g. wind power station for supplying electrical power to consumer in single family house, has control controlling delivery and receiving of energy from/by mains

摘要

The storage (1) has a control (4) controlling delivery of energy from electricity mains (2) and receiving of energy by the electricity mains, where the storage unit is designed as a fixed storage unit. The control detects frequency of alternating current or voltage in the mains. The control communicates with a network interface (14), where communication with the interface is implemented via a spacer. The memory exhibits memory capacity of less than 1000 kilowatt-hour or 100 kilowatt-hour. The control implements the control function based on information about electricity cost. An independent claim is also included for a system for electric power supply of a consumer.
