Solar automatic balancing battery components

Abstract

The present invention discloses an automatic solar energy balancing battery assembly, which comprises a battery management module, a bottom case, a battery pack positioned inside the bottom case and an upper cover, wherein the periphery of the bottom case is respectively provided with a solar energy panel and a rotation base for fixing the solar energy panel, the upper end of the rotation base and the outer side of the bottom case form a rotation connection, the negative electrode end of the battery pack and the negative electrode input end of the battery management module are connected, the positive electrode end and the negative electrode end of the solar energy panel are respectively connected to the positive electrode end and the negative electrode end of the battery pack through the battery management module, and a heat elimination mechanism is arranged in the bottom case, and comprises a fan positioned on the inner bottom portion of the bottom case and capable of blowing upward, and a linkage device for driving the fan to rotate through the rotation base. A purpose of the present invention is to provide the automatic solar energy balancing battery assembly with the characteristic of effective reduction of the uniformity difference of the lithium battery pack during the use process.

Description

technical field [0001] The invention relates to the battery field, in particular to a solar energy automatic balancing battery assembly. Background technique [0002] At present, the pouch cell battery requires a plurality of individual cells to be connected in series to form a battery pack. For example, the Chinese patent authorization announcement number: CN203690392U, authorized announcement date July 2, 2014, discloses a lithium power battery assembly and connection device , including a battery pack, the battery pack is composed of a plurality of batteries, the batteries in the battery pack are arranged side by side in the same direction, the battery pack is provided with a connecting device, the connecting device and the battery cells are set in one-to-one correspondence, and the connecting devices are connected by connecting pieces Fixed connection, each connecting device is provided with a positive pole lug connector and a negative pole lug connector corresponding to ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the differences in the raw materials, components, manufacturing process and micro-environment of the battery, the voltage, capacity, charge and its decay rate, internal resistance and time-dependent change rate, life span, temperature, etc. There are certain differences in parameters such as impact, self-discharge rate and its rate of change over time, which will cause consistency differences in the battery packs after the group is used. The more single batteries participating in the combination, the possibility of differences The bigger it is, especially after the battery pack is used for 2 years, the difference will gradually become obvious, so that the capacity of the battery pack will become lower and the cruising range will be shorter, which will greatly affect the performance and life of the battery pack.
