AI Technical Summary
Technical Problem
In the existing battery pack, the positive and negative electrode lead wires of the heating film are unreasonable, resulting in low space utilization.
Method used
A battery pack is designed, wherein the first conductor and the second conductor of the heating member are drawn out in the second direction by the side of the heating member close to the inner beam, and smoothly drawn out of the conductor is achieved through the avoidance part and the lead-out part of the first end plate, avoiding additional demand for extraction space.
Benefits of technology
The space utilization of the battery pack is improved, wires are prevented from being curled or misaligned, and the positional fixation and connectivity of the heating film are ensured.

Abstract
The utility model relates to the technical field of batteries, and discloses a battery pack and an electric device, according to the battery pack provided by the utility model, a first lead and a second lead of a heating element are led out from one side, close to an internal beam, of the heating element along a second direction, so that the situation that two ends of a battery column along the second direction cannot be tightly attached to a box body frame is avoided; the end, deviating from the internal beam, of the battery column directly abuts against the frame in the second direction, and the space utilization rate of the whole bag is increased. Besides, avoiding parts are formed in the positions, corresponding to the first wire and the second wire, of the end plate, and the avoiding parts are suitable for forming avoiding positions for leading-out of the first wire and the second wire, so that leading-out of the first wire and the second wire is facilitated; no independent lead-out space needs to be reserved for the first wire and the second wire, the thickness of the battery pack in the first direction is prevented from being increased, and the space utilization rate of the battery pack is improved.
