Abstract
The utility model discloses the protective devices of lithium battery group, including battery case, it is equidistant on the roof of the battery case to offer multiple battery cases, the inside of each battery case is equipped with lithium battery, it is symmetrically installed with multiple first springs on bottom wall inside each battery case, the top of first spring is equipped with buffer board, the bottom end of each lithium battery is all provided with that there are two electrodes, and the two poles of the earth of lithium battery are electrically connected with two electrodes respectively, jack corresponding with electrode position there are two being opened up on each buffer board, installing port there are two symmetrically being opened up on bottom wall inside each battery case, the inside of two installing ports is mounted on second spring.The utility model is simple in structure, easy to operation, and the mounting means by changing conventional batteries makes single lithium battery be easier to be removable and replaceable, while not influencing its normal work and having certain pooling feature, efficiently convenient, is worthy to be popularized.
Description
Technical field
The utility model is related to the protective devices of technical field of lithium batteries more particularly to lithium battery group.
Background technology
In recent years, with the rapid proliferations such as portable electricity consuming products, small household appliance, electric tool, electric vehicle, lithium electricity
Due to the advantages that capacity is high, have extended cycle life, memory-less effect, low and environmentally protective self-discharge rate, becoming many needs can in pond
The electronics of charging cell, the power resources of electric product.In actual use, it usually needs more lithium battery serial or parallel connections make
With.When multiple single lithium batteries are used in series, since the performance of each single lithium battery is difficult to accomplish completely the same, performance is most
The battery of difference often becomes the bottleneck of whole group power supply.And due to " short -board effect ", the worst battery of performance is usually earlier than other electricity
Pond is full of, and is also vented earlier than other batteries, among charge and discharge cycles repeatedly, this gap can be gradually expanded, and ultimately cause
The deterioration of whole group battery performance.And existing battery pack is difficult to carry out demolition and replacement to single lithium battery after mounting, is needed
Improvement is made to this.
