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.
