Embodiment 1

[0043] like Figure 1-Figure 11As shown, a general-purpose economically compatible BDU of this embodiment includes a positive pole BDU1 and a negative pole BDU2 of split design, the positive pole BDU1 includes a positive pole upper case 11, a positive pole lower case 12, and the positive pole upper case 11 and the positive lower case 12 are detachably connected by a buckle, the negative BDU2 includes a negative upper case 21 and a negative lower case 22, and the negative upper case 21 and the negative lower case 22 are detachably connected by a snap .

[0044] In the BDU of this embodiment, the positive and negative poles are integrated in separate housings, and the upper and lower housings of the positive and negative BDUs are respectively snap-fitted to reduce bolt connections, which can effectively reduce system weight and cost; and because The installation space in the battery pack is limited, and the positive BDU and negative BDU are designed separately, which can effect...

Embodiment 2

[0056] like Figure 11 As shown, a battery pack in this embodiment includes the general-purpose economically compatible BDU and the battery pack body 300, and an installation space is reserved inside the tail of the battery pack body 300, and the positive pole BDU1 and the negative pole BDU2 are respectively arranged side by side in the installation space. The positive BDU1 and the negative BDU2 are in the shape of a cube respectively, and a strip-shaped installation space is formed at the end of the battery pack body 300 , and the positive BDU1 and the negative BDU2 are installed horizontally side by side in the installation space. In the battery pack of this embodiment, due to the limited internal installation space, the positive BDU and the negative BDU are designed separately, which can effectively utilize the limited space in the battery pack, and has a compact structure and saves space.

Abstract

The invention relates to a universal economic compatibility BDU and a battery pack. The BDU comprises a positive electrode BDU and a negative electrode BDU which are designed in a split manner. The positive electrode BDU comprises a positive electrode upper shell and a positive electrode lower shell, wherein the positive electrode upper shell is detachably connected with the positive electrode lower shell through a buckle. The negative electrode BDU comprises a negative electrode upper shell and a negative electrode lower shell, wherein the negative electrode upper shell is detachably connected with the negative electrode lower shell through a buckle. According to the BDU, the positive electrode and the negative electrode are integrated in different shells in a split mode, and the upper shell and the lower shell of the positive electrode BDU and the lower shell of the negative electrode BDU are respectively of a buckle design, thereby reducing the bolt connection, and effectively reducing the weight and cost of a system effectively. Moreover, due to the fact that an installation space in the battery pack is limited, the positive electrode BDU and the negative electrode BDU are designed in the split mode, so the limited space in the battery pack can be effectively utilized, the structure is compact, and the space is saved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a general economically compatible BDU and a battery pack. Background technique [0002] At present, the BDU (Battery Disconnect Unit) as the core electronic control unit is designed for the interior of the battery pack and is also a type of power distribution box. The device plays a vital role in the safety of the battery pack. At present, BDU needs to correspond to different designs for different project requirements, which does not meet the basic principles of design generalization and platformization, and wastes design and development costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a universal economically compatible BDU and battery pack for the deficiencies of the prior art. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a ...
