[0004]The existing liquid metal battery heat preservation system mostly adopts the method of heating around the battery pack and replacing the battery up and down. This method requires a heating partition inside the heat preservation system. It is not conducive to the air flow between the cells of the battery pack, and the temperature difference between the cells of the battery pack is too high, which reduces the consistency of the battery; After stacking, it is not conducive to the subsequent management of liquid metal battery packs, connection of incoming and outgoing lines, service replacement and maintenance, which consumes manpower and material resources, and may even fail to form a stack

The invention discloses a liquid metal battery pack heat preservation box and a heat preservation system, and belongs to the technical field of power grid energy storage batteries, the heat preservation box comprises a bottom plate, a plurality of side plates and a cover plate, one ends of the side plates are arranged on the bottom plate, and the cover plate is arranged at the other ends of the side plates and is opposite to the bottom plate; a heating resistance wire is arranged on the bottom plate; at least one of the side plates is detachably connected with the bottom plate and the cover plate. The invention further provides a liquid metal battery pack heat preservation system which comprises the liquid metal battery pack and the heat preservation box. According to the liquid metal battery pack heat preservation box and the heat preservation system, the temperature difference of the liquid metal battery pack can be reduced, and the consistency of the battery temperature is improved; and the batteries can be conveniently put in before the system is started and replaced after serving, and subsequent stacking and connection of large-scale battery groups are also facilitated.
Description
technical field [0001] The invention belongs to the technical field of power grid energy storage batteries, and more particularly relates to a liquid metal battery pack incubator and an insulation system. Background technique [0002] At this stage, renewable energy power generation and energy storage technology has become a research and development hotspot around the world. Among them, cost, life and efficiency are the key factors restricting the large-scale application of energy storage. At present, relatively mature energy storage batteries include lithium-ion batteries, sodium-sulfur batteries, and flow batteries. However, due to the limitations of key materials and technologies, their energy storage costs are still high, and they are not widely used in large-scale grid energy storage. [0003] Liquid metal batteries are an inexpensive and efficient electrochemical energy storage technology proposed in recent years, providing a new option for grid-scale energy storage. ...
