Therefore, a battery management system, referred to as a BMS protection board for short, with a specific lithium battery management system must be provided for the lithium battery, so as to effectively monitor, protect, balance energy and alarm faults of the battery pack, and further improve the working efficiency and service life of the whole lithium battery.
The battery core of the current battery replacement lithium battery is arranged in a battery box body, the box body in the prior art is divided into two parts, namely an upper battery cover and a lower battery box body, the battery core is usually arranged in the lower box body, and a BMS protection plate is arranged in the upper battery cover. The BMS protection board contains a plurality of high-power heating components in the battery use process, so that the battery use potential safety hazard is caused due to self heating, the service life of the whole battery is influenced, and the potential safety hazard is not widely taken into account in the prior art, so that corresponding use faults and accidents occur. Especially, when the upper cover and the lower case of the battery case are both made of plastic materials, the dangerous situation is even greater. Although the heat dissipation aluminum sheet has been provided on the BMS protection plate in the related art, since the BMS protection plate is located in a relatively closed space, it is impossible to achieve a good heat exchange, and a real heat dissipation effect is not actually achieved.
The utility model has the following contents:
an object of the utility model is to provide a simple structure, and can realize the heat dissipation upper cover that trades electric battery of good heat exchange.
The utility model discloses a realize like this during the purpose:
a heat dissipation upper cover of a battery replacement comprises a metal upper cover body with a deep shell structure, and is characterized in that the upper surface of the metal upper cover body comprises a heat dissipation area and an output function area, and the heat dissipation area is provided with a concave-convex heat dissipation structure; and a heat dissipation contact surface is arranged on the inner surface of the metal upper cover body at a position corresponding to the heat dissipation area.
The concave-convex heat dissipation structure is a concave-convex strip structure which is arranged in parallel.
The heat dissipation contact surface is a square contact surface.
The heat dissipation contact surface is a rectangular contact surface.
A BMS protection board cabin body is arranged at the position corresponding to the heat dissipation area in the metal upper cover body.
And the output function area of the outer surface of the metal upper cover body is provided with two groups of lead output interfaces.
The outer surface of the metal upper cover body is provided with a hand-held handle.
The portable handle of the metal upper cover body is connected with the surface of the metal upper cover body through a movable hinge.
The utility model discloses simple structure has enlarged heat exchange area, has guaranteed that high-power heating element on the BMS protection shield has a good heat radiation environment, has improved prior art's defect to the safety in utilization that trades the battery of assurance, and can prolong the life who trades the battery.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention
FIG. 2 is a schematic view of the outer surface of the present invention
FIG. 3 is a schematic view of the inner structure of the cover of the present invention
Fig. 4 is the utility model discloses the cross-sectional view behind the assembly BMS protection shield
The specific implementation mode is as follows:
the present invention will be further described with reference to fig. 1, 2, 3 and 4.
The utility model discloses a design is that the battery upper cover that utilizes among the prior art carries out structural change, lets the battery upper cover wholly as a radiating conductor to let the high-power components and parts that generate heat on the BMS protection shield can the direct contact battery upper cover, realize the enlargement of heat exchange area and environment, thereby improve the radiating efficiency.
For realizing above-mentioned technical thought, in this embodiment, the utility model discloses a dark shell structure's metal upper cover body 1, so-called dark shell structure is that the utility model discloses need have one can hold BMS protection shield and other conventional electronic components's in trading the battery space, this part is the same with prior art.
