Problems solved by technology

[0006] In addition, the battery packs of some batteries are large in size and high in weight. When moving and handling, because the automatic logistics production line has not kept up, it takes a lot of physical strength of workers to carry them manually, which is slow in efficiency and requires high manpower.

Abstract

The invention relates to the field of power battery production, and in particular relates to a convenient power battery. The convenient power battery can be realized through the following technical scheme: the convenient power battery comprises a box body and a battery component installed in the box body, a mobile switching device comprises a walking device and a stagnation device, the walking device comprises a walking frame hinged with the bottom of the box body, an elastic roller connected with the walking frame, and a walking wheel arranged at the end of the elastic roller, the bottom of the box body is provided with an accommodating groove for accommodating the walking frame, and the stagnation device comprises an inclined insertion piece with an adjustable self-extension length which is connected with the bottom of the box body. The purpose of this invention is to provide the convenient power battery, according to different environmental temperature, heat dissipation or heat preservation effects can be adjusted, the electrical performance and service life of the power battery can be improved, and a mobile mode of the battery can be switched by the switching device when in rest and transport.

Description

technical field [0001] The invention relates to the field of power battery production, in particular to a convenient power battery. Background technique [0002] Compared with other batteries, the power battery has high voltage, high energy density, good cycle performance, small self-discharge, [0003] No memory effect, wide operating temperature range and other advantages. The structure of a general lithium-ion power battery is: in the form of laminations, a battery cell formed by interleaving the positive electrode sheet, separator, and negative electrode sheet, or a battery cell made in the form of a winding, and then connected to an external terminal, put into a hard case such as a plastic case, Electrolyte is injected into the steel shell, aluminum shell or aluminum-plastic film. For traditional lithium-ion power batteries, the positive electrode is generally made of nickel-cobalt lithium manganese oxide, lithium iron phosphate, lithium manganese oxide, lithium cobal...
