Battery control unit potting structure and packaging method

Abstract

The invention discloses a packaging method for a battery control unit, and the method comprises the following steps: 1), providing a bottom case with at least one opened side; 2), installing a printedcircuit board on the bottom case; 3), installing a tool fixture at at least opened side of the printed circuit board, and enabling the bottom case and the tool fixture to jointly form an accommodation space for accommodating a pouring sealant; 4), injecting the pouring sealant into the accommodation space, and removing the tool fixture after the solidification of the pouring sealant; 5), installing an upper cover, and obtaining a battery control unit encapsulating structure. Compared with the prior art, the method has the following advantageous in that 1), the method simplifies a bottom casemodel, a product structure and technology, and saves the cost; 2), the encapsulating range is not limited by a product, and encapsulating structures in various shapes can be designed; 3), the bubblesgenerated inside after the solidification of the pouring sealant through a gap formed by the splicing of the tool fixture, and the encapsulating performance is improved; 4), the weight of the encapsulating structure is reduced. In addition, the invention also discloses a battery control unit encapsulating structure.

Description

technical field [0001] The invention belongs to the field of batteries, and more specifically, the invention relates to a potting structure and a packaging method of a battery control unit. Background technique [0002] The potting process is to mechanically or manually pour potting glue of various components into devices (similar containers) equipped with components, etc., and cure the potting glue under normal temperature or heating conditions and transform it into a polymer insulating material with excellent performance. materials, so as to achieve the purpose of bonding, strengthening, sealing, potting and coating protection. [0003] At present, the common potting structure of the battery control unit is to inject potting compound into an open container tank to realize functions such as sealing, please refer to figure 1 shown. The structure includes an upper cover 10 , a printed circuit board 20 and a bottom case 30 similar to a container structure. Please refer to t...

Problems solved by technology

[0004] However, the existing slot-type potting structure requires sufficient space to realize

With the development of science and technology, the market has higher and higher requirements for light weight and integration of products. Products with light weight, small size and complete functions are more and more popular. The existing battery control unit potting structure can no longer adapt to the market. needs
