Description

External balanced single-string structure of battery pack
Technical Field
The utility model relates to a group battery is maintained and is maintained technical field, concretely relates to outside balanced single cluster structure of group battery.
Background
Lithium battery packs are now widely used in our lives, such as battery bicycles, electric tools, and the like. When the battery pack is used, the longer the service time is, the larger the voltage difference of each string of the battery pack is, and the battery pack is not fully charged and has a short mileage. Then need return to former factory and dismantle battery case and inside material, carry out equalizing charge to electric core again alone, it is troublesome to maintain.
Disclosure of Invention
The utility model aims to solve the technical problem that a balanced single cluster structure in group battery outside is provided, run through the shell through the sampling line that fills port one end with outside equilibrium and connect the BMS board, outside equilibrium fills the power cord that the port other end is connected and connects the electric core group, and is balanced to every cluster battery of group battery, has realized not needing to tear open the shell, just can maintain the maintenance to the battery.
The utility model discloses the outside balanced single cluster structure of group battery is realized through following technical scheme: the battery pack comprises a shell, and a battery pack and a BMS board which are arranged in the shell; the shell is provided with a charge-discharge port and an external balanced charge port;
the sampling line that port one end was connected is filled in outside equilibrium runs through the shell and connects the BMS board, and the power cord that the port other end was connected is filled in outside equilibrium connects the electric core group.
As the preferred technical scheme, the power cord that fills and discharge port one end and connect is connected with the BMS board, and the power cord that fills and discharge port other end and connect the electric core group.
As a preferred technical scheme, the electric core group comprises more than one battery; more than one battery is provided with a nickel strap.
The beneficial effects of the utility model are that:
1. the sampling line connected with one end of the external balanced charging port penetrates through the shell to be connected with the BMS board, and the power line connected with the other end of the external balanced charging port is connected with the battery core group, so that each string of batteries of the battery pack is balanced, and the batteries can be maintained without disassembling the shell;
2. the battery can be used for maintaining and repairing, the voltage difference exists in the battery cell, the electricity is supplemented, and the voltage of the battery pack can be consistent. The problem that the battery is overcharged and the mileage is too short due to the problem of pressure difference can be well solved.

Fig. 1 is a schematic cross-sectional view of an external balanced single-string structure of a battery pack according to the present invention;
fig. 2 is a first schematic diagram of a battery pack external balanced single-string structure with a hidden housing according to the present invention;
fig. 3 is a schematic diagram two of the external balanced single-string structure of the battery pack with the hidden housing according to the present invention;
fig. 4 is a third schematic diagram of the battery pack external equalization single-string structure of the hidden housing of the present invention.
Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
As shown in fig. 1-4, the external equalization single string structure of battery pack of the present invention comprises a housing, and a battery cell pack and a BMS board installed in the housing; the shell is provided with a charge-discharge port and an external balanced charge port; a sampling line 100 connected with one end of the external balanced charging port penetrates through the shell to be connected with the BMS board, and a power line 101 connected with the other end of the external balanced charging port is connected with the battery pack.
In this embodiment, the sampling line 100 is a conventional one; the power line connected with one end of the charging and discharging port is connected with the BMS board, and the power line connected with the other end of the charging and discharging port is connected with the electric core group; the electric core group comprises more than one battery 6; the nickel strap 7 is arranged among more than one battery 6, the sampling wire connected with one end of the external balanced charging port penetrates through the shell to be connected with the BMS board, the power wire connected with the other end of the external balanced charging port is connected with the electric core group, and each string of batteries of the battery pack are balanced; the battery can be used for maintaining and maintaining, the voltage difference exists in the battery cell, electricity is supplemented, the voltage of the battery pack can be consistent, and the problems that the battery is overcharged and the mileage is too short due to the voltage difference can be well solved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
