Abstract
The utility model discloses a passive equalizer, including the battery package, still include the control circuit board that discharges, every battery in the battery package all passes through wire and control circuit board electric connection that discharges. The utility model discloses a discharge control circuit board can be with the battery self-discharge absorption in the battery package, avoids each battery voltage difference in the battery package too big, ensures the security and the life of battery package.
Description
Technical Field
The utility model relates to a lithium cell technical field specifically is a passive equalizer.
Background
During the use of the battery pack, the capacity is continuously reduced, and the capacity is reduced due to two reasons, wherein one reason is that the voltage difference of each battery in the battery pack is too large due to the self-discharge difference, so that the safety and the service life of the battery pack are influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a passive equalizer to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: a passive equalizer comprises a battery pack, and is characterized in that: still include the control circuit board that discharges, every battery in the battery package all passes through wire and the control circuit board electric connection that discharges.
Furthermore, the two sides of the battery pack are respectively provided with a radiating fin.
Further, the lead is arranged to penetrate through the mounting plate.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model discloses a discharge control circuit board can be with the battery self-discharge absorption in the battery package, avoids each battery voltage difference in the battery package too big, ensures the security and the life of battery package.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals:
1 battery package, 2 discharge control circuit boards, 3 fin, 4 mounting panels, 5 wire.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, a passive equalizer includes a battery pack 1 and a discharge control circuit board 2, and each battery in the battery pack 1 is electrically connected to the discharge control circuit board 2 through a wire 5. Specifically, the discharge control circuit board 2 can absorb the self-discharge of the battery in the battery pack 1, so that the voltage difference of each battery in the battery pack is avoided being too large, and the safety and the service life of the battery pack are ensured; the discharge control circuit board 2 can control the voltage of the battery self-discharge, so that the voltage difference of the battery is determined to be small, and the safety and the service life of the battery pack are ensured.
In this embodiment, the heat dissipation fins 3 are provided on both sides of the battery pack 1. The heat radiating fins 3 radiate heat emitted by the battery pack, so that normal use of the battery pack 1 is ensured.
In this embodiment, the wires 5 are arranged to penetrate the mounting plate 4, thereby ensuring that the wires are not knotted or wound.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
Claims (2)
1. A passive equalizer comprising a battery pack, characterized in that: still include the control circuit board that discharges, every battery in the battery package all passes through wire and control circuit board electric connection that discharges, the both sides of battery package set up the fin respectively.
2. A passive equalizer according to claim 1, characterized in that: the wire runs through the mounting plate.
