Description

Battery box integrated panel, battery pack and power supplementing circuit structure Technical Field The application relates to the technical field of power batteries, in particular to a battery box integrated panel, a battery pack and a power supplementing circuit structure. Background With the gradual development of new energy technology, more and more vehicles begin to use lithium batteries as power sources. In the specific application process, as the service time of the power battery is gradually increased, the consistency of the electric core in the battery box may be problematic, so that the pressure difference between the single electric cores is gradually increased, the use of the power battery is affected, and the battery box needs to be overhauled at the moment. In the prior art, when the battery box is overhauled, the battery box is generally required to be integrally disassembled, and then the internal battery cells are subjected to power compensation equalization. At this time, the battery pack needs to be detached integrally, and then the battery box is detached again, so that the whole overhaul process is complicated. Meanwhile, the working site is often poor in environment, the direct disassembly can damage the internal battery cell and other structures, and the repair process is more complicated when the battery cell is returned to the factory for maintenance, so that the cost is increased. Therefore, it is desirable to provide a battery box structure, which can simplify the whole maintenance process of the battery box and reduce the maintenance cost. Disclosure of utility model The application aims to provide a battery box integrated panel, a battery pack and a power supplementing circuit structure, which can simplify the whole maintenance process of a battery box and reduce maintenance cost. In order to achieve the above object, the present application provides, in a first aspect, a battery case integration panel provided on a case of a battery pack.
