Abstract
The utility model discloses a single-string structure for balancing the outside of a battery pack, which comprises a shell, a battery cell pack and a BMS board, wherein the battery cell pack and the BMS board are arranged in the shell; the shell is provided with a charge-discharge port and an external balanced charge port; a sampling line 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 connected with the other end of the external balanced charging port is connected with the battery pack; the utility model discloses a run through the shell with the sampling line that outside balanced filling port one end is connected and connect the BMS board, outside balanced filling the power cord that the port other end is connected and connect the electric core group, it is balanced to every cluster battery of group battery, has realized not needing to tear the shell open, just can maintain the maintenance to the battery.
Description
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.
