Description

Technical Field

[0001] The present invention relates to the technical field of battery maintenance instruments, and particularly to a portable single-cell battery maintenance instrument with an equalization maintenance function. Background Art

[0002] A battery equalization maintenance instrument is an instrument for solving the equalization problem caused by the differences between batteries. Generally, a battery maintenance instrument is connected to the positive and negative electrodes of a battery to maintain the battery. After maintaining one battery, traditional battery maintenance instruments require manual replacement of another battery for maintenance. The frequency of battery replacement is high, increasing the labor burden of the staff.

[0003] The defects of existing battery maintenance instruments are as follows:

[0004] 1. The prior art KR1020070001084A discloses a battery maintenance device for a fuel cell stack. This technology does not have a structure for storing batteries. After maintaining one battery, it is necessary for the staff to promptly place another battery for maintenance. The frequency of battery replacement is high, and the workload of the staff is large. Therefore, a portable single-cell battery maintenance instrument with an equalization maintenance function and a battery storage structure to reduce the frequency of battery replacement by the staff is needed to solve this problem.

[0005] 2. The prior art US20080143299A1 discloses battery maintenance. This technology does not have a structure for storing the battery maintenance structure. The battery maintenance structure is large in volume and complex in structure, making it inconvenient to carry. Therefore, a portable single-cell battery maintenance instrument with an equalization maintenance function that can store the battery maintenance structure to reduce the occupied space of the battery maintenance structure is needed to solve this problem.

[0006] 3. The prior art US20160285284A1 discloses a battery maintenance system. This technology does not have a structure that is convenient for simultaneously maintaining batteries of different heights. When maintaining batteries of different heights, it is necessary for the staff to adjust the relative position of the battery maintenance structure and the battery, and the adjustment process is complex. Therefore, a portable single-cell battery maintenance instrument with an equalization maintenance function and a structure that is convenient for simultaneously maintaining batteries of different heights is needed to solve this problem.

Place the cylindrical battery into the cylinder body (13), then the motor (7) drives the cylinder body (13) to move below the first conductive cylinder (20), and then the electric telescopic unit two (17) drives the first conductive cylinder (20) to move downward to contact the top electrode end of the cylindrical battery; S2. Subsequently, the electric telescopic unit three (22) drives the second conductive cylinder (25) to move upward to contact the bottom electrode end of the cylindrical battery; S3. The maintenance instrument body (1) is electrically connected to the cylindrical battery through the first conductive cylinder (20) and the second conductive cylinder (25), thereby maintaining the cylindrical battery; S4. After the maintenance of the cylindrical battery is completed, the first conductive cylinder (20) moves upward, the second conductive cylinder (25) moves downward, and then after the motor (7) drives the rotating wheel (10) to rotate by a set angle, the first conductive cylinder (20) moves downward again, and the second conductive cylinder (25) moves upward again to maintain a new round of cylindrical batteries; S5. When the maintenance instrument body (1) is no longer in use, the electric telescopic unit one (2) drives the conveyor belt (12) to move backward, thereby reducing the occupied space of the conveyor belt (12) and facilitating carrying; S6. The electric telescopic unit four (27) drives the protective frame (31) to move downward to protect the front surface of the maintenance instrument body (1).

6. The usage method of a portable single-cell battery maintenance instrument with an equalization maintenance function according to claim 5, characterized in that: The following steps are also included in the S5: S51. At the same time, the staff opens the first sticky fastener (15) and the second sticky fastener (16) on the conveyor belt (12) to loosen the conveyor belt (12), so that the conveyor belt (12) is convenient to move backward, and then the first sticky fastener (15) and the second sticky fastener (16) are stuck again.
