Title:
ENERGY STORAGE SYSTEM AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/082687
Kind Code:
A1
Abstract:
The present application provides an energy storage system and a power supply system. The energy storage system comprises a battery pack, a power conversion assembly, a first liquid flow channel, a second liquid flow channel, a first driving device, a second driving device, and a flow distribution member. The first liquid flow channel is in thermally conductive contact with the battery pack, and the first driving device is communicated with the first liquid flow channel. The second liquid flow channel is in thermally conductive contact with the power conversion assembly, and the second driving device is communicated with the second liquid flow channel. The flow distribution member is separately communicated with the first liquid flow channel and the second liquid flow channel. When the flow distribution member is in a first working state, the first liquid flow channel is isolated from the second liquid flow channel. Control can be performed respectively according to temperature requirements of the battery pack and the power conversion assembly. When the flow distribution member is in a second working state, the first liquid flow channel is communicated with the second liquid flow channel to form an integral loop, and the heat of the power conversion assembly is used for heating the battery pack. A temperature control scheme can be adjusted according to working states, the space occupied by the energy storage system is reduced, and power consumption is reduced.
