Title:
SWITCH DEVICE AND POWER STORAGE SYSTEM
Document Type and Number:
Japanese Patent JP2014239561
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To adjust, with a simple configuration, voltage and current according to an output destination, in a system where an output destination of generated power is switched.SOLUTION: A serial/parallel switching unit 20 performs switching between: connecting a power conditioner 210 with a single output system into which a plurality of output systems of a plurality of DC power sources for generating power are integrated so that the plurality of DC power sources are connected in series; and connecting a storage battery with a single output system into which the plurality of output systems are integrated so that the plurality of DC power sources are connected in parallel, through a charge/discharge circuit 120. The serial/parallel switching unit 20 includes: a plurality of relays for connection destination switching corresponding to the plurality of output systems, respectively; and a relay for state detection for detecting connection states of the plurality of relays for connection destination switching. The plurality of relays for connection destination switching and the relay for state detection are driven by the same coil.
