Title:
POWER APPARATUS AND ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/008141
Kind Code:
A1
Abstract:
A power apparatus and an energy storage system. The power apparatus (10) comprises a power source (100), reciprocating assemblies (200), and compression assemblies (300). The power source (100) drives reciprocating members (220) to reciprocate in the axial directions of power shafts (210) so as to drive pistons (320) to reciprocate along the axes of the power shafts (210). First piston bodies (321) are provided in first compression chambers (330), and second piston bodies (322) are provided in second compression chambers (340). When each piston (320) moves in one direction, the first piston bodies (321) compress gas in the first compression chambers (330) into the second compression chambers (340). When each piston (320) moves in the other direction, the second piston bodies (322) compress a gas medium in the second compression chambers (340) so as to discharge same by means of second channels (360); and at this time, gas enters the first compression chambers (330) by means of first channels (350). The power shafts (210) of the two reciprocating assemblies (200) are both driven by the power source (100), thereby achieving synchronous compression of the two compression assemblies (300) and improving compression efficiency, and two-side two-stage compression is achieved by means of one power source (100), thus making the compression efficiency higher, and the size of the power apparatus (10) smaller.
