[0002] Currently, sampling of a high-voltage circuit is generally performed by fixing a terminal at the end of a sampling wire and using a bolt to fix the terminal on a copper bar of the high-voltage circuit. However, this sampling method has low connection efficiency and is inconvenient to assemble. CONTENT OF THE UTILITY MODEL

[0003] The application aims to provide a high-voltage control device, a battery device, an energy storage device, an energy storage system, a power consumption device, and a charging network to improve the problem of low connection efficiency and inconvenience in assembling of a high-voltage circuit in the related art.

[0004] In a first aspect, the application provides a high-voltage control device, comprising:

[0005] a high-voltage circuit, the high-voltage circuit comprising a conductive bar for conducting current;

[0006] a sampling board, the sampling board being provided with a sampling circuit;

[0007] an elastic conductive member, the elastic conductive member being fixed to the sampling board and electrically connected to the sampling circuit;

[0008] the elastic conductive member elastically abutting against the conductive bar.

[0009] In the technical solution of the application, the sampling board is provided, and the sampling circuit and the elastic conductive member are arranged on the sampling board, so that the elastic conductive member is connected to the sampling circuit. During assembly, the sampling board is only needed to be fixed, and the elastic conductive member elastically abuts against the conductive bar of the high-voltage circuit. The sampling circuit can be electrically connected to the conductive bar to collect information such as current and voltage conducted by the conductive bar. The assembly is simple, and the connection efficiency is high. Since the elastic conductive member elastically abuts against the conductive bar, stable connection can be well maintained, and the risk of loose connection is effectively reduced.

[0010] In some embodiments, the elastic conductive member comprises a spring piece, the spring piece being fixedly connected to the sampling board, and a part of the spring piece protruding from the sampling board and elastically abutting against the conductive bar.

[0011] The elastic conductive member uses a spring piece, which has a simple structure and can elastically abut against the conductive bar well, facilitating assembly and use.

[0012] In some embodiments, the elastic sheet comprises a first segment, a middle segment and a second segment connected in sequence along a first direction; the first segment is fixedly connected to the sampling plate; the middle segment is arched at a middle portion thereof along the first direction towards a direction away from the sampling plate; and the second segment is arranged by the middle segment towards a direction away from the first segment and is used to elastically abut against the sampling plate.

[0013] The first segment is arranged to be fixedly connected to the sampling plate, thereby fixing the elastic sheet to the sampling plate; the middle segment is arranged to elastically abut against the conductive row; and the second segment is arranged to move towards the sampling plate under the reaction force of the conductive row when the sampling plate approaches the conductive row and the middle segment abuts against the conductive row, thereby elastically supporting the middle segment so that the middle segment can more stably abut against the conductive row.

[0014] In some embodiments, the elastic conductive member comprises a spring, one end of the spring is fixedly connected to the sampling plate, and the other end of the spring elastically abuts against the conductive row.

[0017] The spring uses a conical spring, which can not only well abut against the conductive row, but also improve the stability along the radial direction of the conical spring, so that the conical spring can more stably abut against the conductive row.

[0018] In some embodiments, the conical bottom surface of the conical spring is connected to the sampling plate.

[0019] Connecting the conical bottom surface of the conical spring to the sampling plate can make the contact area of the conical spring with the sampling plate larger, so as to fixedly support the conical spring and facilitate the conical top surface of the conical spring to abut against the conductive row.

[0020] In some embodiments, the spring is made of a conductive wire, and the cross section of the conductive wire is square.

[0021] The cross section of the conductive wire is square, so that the conductive wire can form a surface contact with the conductive row when the spring abuts against the conductive row, thereby increasing the contact area of the spring with the conductive row and reducing the contact resistance, so as to collect information of the circuit in which the conductive row is located.

[0022] In some embodiments, the elastic conductive member comprises a conductive glue block fixed to the sampling plate.

[0023] The elastic conductive member uses a conductive glue block, which is simple in structure and can abut against the conductive row with a larger contact area, so as to make the contact resistance smaller and collect information of the circuit in which the conductive row is located.

[0024] In some embodiments, the elastic conductive member comprises a conductive clamp, the conductive clamp comprising an elastic clamp for clamping the conductive strip and a conductive support for supporting the elastic clamp, the conductive support being fixedly connected to the sampling board.

[0025] The elastic clamp can be used to conveniently clamp the conductive strip and maintain good contact with the conductive strip. The conductive support can be used to conveniently connect the sampling board and support the elastic clamp, so that the elastic clamp can clamp the conductive strip.

[0026] In some embodiments, the high-voltage circuit comprises a plurality of conductive strips, and the sampling board comprises a plurality of sampling lines, each of the sampling lines being connected to at least one elastic conductive member.

[0027] The plurality of sampling lines on the sampling board are respectively connected to the elastic conductive members, so that the plurality of positions of the high-voltage circuit can be sampled through the plurality of sampling lines to better monitor the information of the high-voltage circuit.

[0028] In some embodiments, the sampling board is a circuit board, and the sampling lines are conductive lines arranged in the circuit board.

[0029] The sampling board uses a circuit board, and the conductive lines are arranged in the circuit board to form the sampling lines, so that the processing and manufacturing are facilitated, and the layout and use of the wires are reduced.

[0030] In some embodiments, the sampling board is provided with pads connected to the sampling lines, and the elastic conductive members are welded to the pads.

[0031] The pads are arranged on the sampling board to facilitate the connection of the elastic conductive members, so that the elastic conductive members are electrically connected to the sampling lines.

[0065] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone.

[0071] The device using the battery, such as electric vehicle and energy storage device, generally has a high-voltage circuit for large-current charging and discharging control and use.
