Abstract

The disclosure relates to a technical field of batteries, and in particular, relates to a battery pack. The battery pack includes a box body, a beam, a battery apparatus, and an electrical support base. The beam is disposed in the box body. The battery apparatus is disposed in the box body, and an electrical conductor is disposed on the battery apparatus. The electrical support base is disposed on the beam. The electrical conductor extends from the battery apparatus to the electrical support base and is connected to the electrical support base.

First claim

What is claimed is:

1. A battery pack, comprising:
a box body;
a beam, disposed in the box body, wherein the beam divides the box body into battery compartments;
battery assemblies, wherein each of the battery assemblies comprises two or more batteries, the battery assemblies are respectively disposed in the battery compartments, and an electrical conductor is disposed on each of the battery assemblies; and
an electrical support base, disposed on the beam, wherein the electrical conductor extends from the battery assemblies to the electrical support base and is connected to the electrical support base, and the electrical conductors on the battery assemblies are directly connected to the same electrical support base,
wherein the electrical support base comprises:
a base body, connected to the beam, wherein the electrical conductor is connected to the base body; and
a protective cover, connected to the base body, wherein a cover body at least covers a junction between the base body and the electrical conductor,
wherein the base body is provided with a first connecting portion, and the electrical support base further comprises:
a first reinforcing member, disposed on the first connecting portion; and
a first connecting member, penetrating the first reinforcing member to connect the base body and the beam,
wherein the base body is further provided with a second connecting portion, the electrical conductor is an electrically conductive bar, and electrically conductive bars of a plurality of battery assemblies are connected to the same second connecting portion,
wherein the electrical support base further comprises:
a second reinforcing member, disposed on the second connecting portion, wherein the second reinforcing member is configured to be connected to the electrical conductor, and the second reinforcing member protrudes from a surface of the base body away from the beam,
wherein the base body has a first surface and a second surface opposite to each other, the second reinforcing member protrudes from the first surface of the base body, and a surface of the second reinforcing member away from the second surface of the base body is higher than the first surface by 0.2 millimeters to 0.4 millimeters.

2. The battery pack according to claim 1 , wherein a plurality of battery assemblies is disposed in the box body, and electrical conductors on the battery assemblies are connected to the same electrical support base.

3. The battery pack according to claim 2 , wherein the electrical conductors continuously extend from the battery assemblies to the electrical support base.

4. The battery pack according to claim 1 , wherein the electrical conductor is a signal acquisition line of the battery assemblies, and the electrical support base further comprises:
a connector, disposed on the base body, the protective cover is configured to protect the connector, and the signal acquisition line is connected to the connector.

5. The battery pack according to claim 1 , wherein the electrical support base is disposed on a side of the beam away from the box body.

6. The battery pack according to claim 1 , wherein the box body further comprises:
a bottom plate; and
a border frame, connected to the bottom plate, wherein the beam and the border frame form a plurality of accommodating portions, and the battery assemblies are disposed in the accommodating portions.

7. The battery pack according to claim 2 , wherein the box body further comprises:
a bottom plate; and
a border frame, connected to the bottom plate, wherein the beam and the border frame form a plurality of accommodating portions, and the battery assemblies are disposed in the accommodating portions.

8. The battery pack according to claim 3 , wherein the box body further comprises:
a bottom plate; and
a border frame, connected to the bottom plate, wherein the beam and the border frame form a plurality of accommodating portions, and the battery assemblies are disposed in the accommodating portions.

9. The battery pack according to claim 4 , wherein the box body further comprises:
a bottom plate; and
a border frame, connected to the bottom plate, wherein the beam and the border frame form a plurality of accommodating portions, and the battery assemblies are disposed in the accommodating portions.
