Embodiment Construction

[0018] see figure 1 , the battery core module 100 with nanocomposite coating of the present invention includes at least one battery pack 1 , at least one circuit board 2 and a plurality of wires 3 .

[0019] see figure 1 and figure 2 , the battery pack 1 includes a plurality of batteries 11 and at least two bus lines 12 , and the surface of the metal barrel 101 of the batteries 11 is coated with a first nano-coating 111 . The first nano coating 111 is composed of a first polymer waterproof coating 41, and the first polymer waterproof coating 41 is composed of polyurethane (PU) resin, alkyd resin, diluent and titanium dioxide (TiO2). It has the characteristics of insulation, waterproof and corrosion resistance. Its insulating property can prevent the metal barrels 101 of the multiple batteries 11 from being disconnected due to mutual contact when the multiple batteries 11 are arranged mutually, thereby causing the battery pack 1 to be damaged.

[0020] Specifically, the co...

Abstract

The invention discloses a battery cell module with a nano-composite coating, which comprises at least one battery pack, wherein the battery pack is composed of a plurality of batteries and at least two buses, the surface of a metal barrel body of each battery is coated with a first nano-coating, the first nano-coating is composed of a first macromolecule waterproof coating, the at least two buses are respectively arranged on the two electrodes of each of the plurality of batteries, each battery is connected with the buses through a plurality of leads so that the plurality of batteries can be connected in series and in parallel, and the buses and the exposed two electrodes of each of the plurality of batteries connected with the buses are coated with a second nano coating, and the second nano coating is formed by coating a second macromolecule coating and a first macromolecule coating in sequence; and at least one circuit board connected with the buses through a plurality of wires, wherein a third nano coating coats the circuit board, and the third nano coating is formed by coating a first solution, a third macromolecule coating, a second macromolecule coating, a first macromolecule coating and a second solution in sequence, the plurality of wires are coated with a fourth nano coating at the soldering positions of the batteries, the buses and the circuit board, and the fourth nano coating is formed by coating a third macromolecule coating and a first macromolecule coating in sequence.

Description

technical field [0001] The invention provides a battery core module, in particular relates to a battery core module with a nanocomposite coating. Background technique [0002] The previous battery module is covered with an external waterproof structure to prevent water from penetrating into the battery module. However, when the waterproof structure fails due to damage, water can seep into the interior of the battery module, resulting in a short circuit of the internal batteries and circuit boards, resulting in damage to the battery pack, and even the risk of fire or explosion. [0003] Therefore, it is necessary to provide a battery core module with a nanocomposite coating, which can make the surface of the internal parts of the battery module insulated and waterproof, so as to improve the safety of the battery module and prolong the life of the battery pack in harsh environments. service life. Contents of the invention [0004] In order to achieve the above object, the ...
