Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Fig. 1 shows a structural explosion diagram of a battery pack of an electric bicycle according to an embodiment of the present invention, and fig. 2 shows a perspective view of the battery pack of the electric bicycle according to an embodiment of the present invention. The utility model discloses an embodiment provides an electric bicycle's battery package, as shown in fig. 1 or fig. 2, this electric bicycle's battery package can include:

the bottom box 1, the inside of the bottom box 1 can be provided with a plurality of partition boards 101 used for dividing the internal space of the bottom box 1;

the battery cells 2 are arranged in the bottom box 1;

the plurality of plug boards 3 are used for filling gaps between the battery cells 2 and the partition boards 101;

the box cover 4, the box cover 4 can be connected with the bottom box 1, and the bottom box 1, the inserting plate 3 and the box cover 4 can be made of flame retardant materials.

The embodiment of the utility model provides an electric bicycle's battery package's end box 1, picture peg 3 and lid 4 are fire resistive material and make, have greatly improved this electric bicycle's battery package's fire behaviour.
