[0080] New energy vehicles in vehicles are usually provided with a high-voltage distribution box, and the high-voltage distribution box is arranged outside the battery module and used for connecting a total positive connection terminal and a total negative connection terminal of a power battery, so as to realize the distribution of the energy of the battery module.

[0081] The high-voltage distribution box includes a Hall sensor and a busbar. When the busbar is arranged around the Hall sensor, the current flowing through the busbar will affect the sampling accuracy of the Hall sensor, and the abnormal calculation of the residual capacity of the battery module is prone to occur.

[0084] The structure in the embodiment of the present application will be described in detail below with reference to the drawings.

[0085] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the electric device provided by some embodiments of the present application is shown. The electric device can be a vehicle 200, wherein the vehicle 200 can be a fuel automobile, a gas automobile or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile or a range extended automobile. The vehicle 200 is internally provided with a battery device 100, which can be arranged at the bottom, the head or the tail of the vehicle 200. The battery device 100 can be used for power supply of the vehicle 200, for example, the battery device 100 can be used as an operating power supply of the vehicle 200. The electric device can further comprise a controller 300 and a motor 400, the controller 300 is used to control the battery device 100 to supply power to the motor 400, for example, to meet the working power demand of the vehicle during starting, navigation and driving.

[0086] In some embodiments of the present application, the battery device 100 can not only be used as an operating power supply of the electric device, but also be used as a driving power supply of the electric device, instead of or partially instead of fuel or natural gas to provide driving power for the electric device.

[0087] As shown in Figure 2 , the battery device 100 comprises a box assembly 11 and a plurality of battery monomers 10, the box assembly 11 forms an accommodation space 113 for accommodating the battery monomers 10.

[0088] It should be noted that, as Figure 2As shown, the box assembly 11 includes a first box 111 and a second box 112, which enclose a containing space 113 for placing the battery monomers 10, and the battery monomers 10 are connected in series, in parallel, or in a hybrid connection, etc.

[0089] Optionally, the battery device 100 further includes a high-voltage distribution box 20, wherein the high-voltage distribution box 20 is electrically connected with the battery monomers 10, and is responsible for reasonably distributing high-voltage electric energy from the plurality of battery monomers 10 to various high-voltage electrical equipment, such as motor controllers, drive motors, electric air conditioner compressors, heaters, and converters, etc.

[0090] The structure of the high-voltage distribution box 20 will be described in detail below.

[0091] As shown, Figures 3 to 8 The high-voltage distribution box 20 includes a first busbar 26, a Hall sensor 21, and a second busbar 22, the first busbar 26 extends along a first direction, and the Hall sensor 21 is sleeved on the first busbar 26; the second busbar 22 is arranged in a spaced manner with the first busbar 26, and the second busbar 22 is arranged on the outer side of the periphery of the Hall sensor 21, at least part of the second busbar 22 is in a bent structure along the first direction, and at least part of the bent structure is arranged opposite to the Hall sensor 21.

[0092] The Hall sensor here is a sensor based on the Hall effect, mainly used for detecting the change of the magnetic field and converting it into an electrical signal, wherein the Hall effect refers to the generation of an electromotive force in the direction perpendicular to the current and the magnetic field when the current passes through a semiconductor sheet placed in a magnetic field, which is called the Hall effect. The Hall sensor is usually composed of a Hall element, an amplifier, a filter, and an output stage, which can amplify the Hall potential and convert it into a standard electrical signal output.

[0093] Optionally, the high-voltage distribution box 20 further includes a box body 27, wherein the first busbar 26, the Hall sensor 21, and the second busbar 22 are all arranged in the space enclosed by the box body 27, wherein the first busbar 26 can be a straight structure or an L-shaped structure, regardless of whether the first busbar 26 is a straight structure or an L-shaped structure, the first busbar 26 has a part arranged in a straight line, and the Hall sensor 21 is sleeved on the straight section of the first busbar 26, which can detect and measure the magnetic field around the first busbar 26.

[0094] At least part of the second busbar 22 is in a bent structure along the first direction, that is, at least part of the second busbar 22 is in a non-straight structure along the first direction, and can be bent along a direction perpendicular to the first direction to form a bent structure.

[0095] Both the first busbar 26 and the third busbar 28 can be fixedly installed on the housing 27 using bolts or other components, making it convenient to disassemble or replace the first busbar 26 and the third busbar 28.

[0096] It should be noted that the first direction here is... Figure 3 The XX direction refers to the width direction of the high-voltage distribution box 20, and the YY direction refers to the length direction of the high-voltage distribution box 20. Both the first busbar 26 and the second busbar 22 extend along the XX direction, and the second busbar 22 and the first busbar 26 are spaced apart along the YY direction. When the spacing between the first busbar 26 and the second busbar 22 is relatively close, the current flowing through the second busbar 22 will affect the sampling accuracy of the Hall sensor 21. The high-voltage distribution box 20 also includes a third busbar 28, which is far from the first busbar 26. In this case, the current generated by the third busbar 28 has a very small and negligible impact on the Hall sensor 21. Therefore, the third busbar 28 can adopt a straight structure, or it can be a bent structure, using the same or similar structure as the second busbar 22.

[0097] The spacing between the first busbar 26 and the second busbar 22 is typically less than 10 mm. Therefore, the current flowing through the second busbar 22 will affect the detection accuracy of the Hall sensor 21.

[0098] The outer periphery of the Hall sensor 21 mentioned here refers to the area close to the Hall sensor 21. Because the second busbar 22, located on the outer periphery of the Hall sensor 21, is close to the Hall sensor 21, the current flowing through the second busbar 22 will significantly affect the sampling of the Hall sensor 21. Furthermore, the statement that at least part of the bent structure is positioned opposite the Hall sensor 21 means that the orthogonal projection of at least part of the bent structure onto the Hall sensor 21 is located on the Hall sensor 21.

[0099] The high-voltage distribution box 20 of this application embodiment, by setting a first busbar 26 and a Hall sensor 21 sleeved on the first busbar 26, and setting a second busbar 22 on the outer periphery of the Hall sensor 21, at least part of the second busbar 22 has a bent structure, and at least part of the bent structure is arranged opposite to the Hall sensor 21, can change the direction of the current flowing through the second busbar 22, so that the current flowing through the second busbar 22 changes from a straight flow to a flow with a bent structure, thereby reducing the impact of the current flowing through the second busbar 22 on the sampling accuracy of the Hall sensor 21.

[0100] Optionally, such as Figures 4 to 8As shown, the second busbar 22 comprises a main body part 221 and a connecting part 222 connected with each other, wherein at least part of the main body part 221 is in a bent structure, and the two ends of the main body part 221 are respectively provided with the connecting part 222.

[0101] Here, the main body part 221 can be entirely in a bent structure or partially in a bent structure. Figure 6 、 Figure 7 and Figure 8 In the above embodiments, the main body part 221 is entirely in a bent structure, so that the direction of the current flowing through the main body part 221 can be changed, thereby reducing the influence of the current flowing through the main body part 221 on the Hall sensor 21.

[0102] Here, the connecting part 222 is located at one end of the main body part 221, and the connecting part 222 can also be provided at both ends of the main body part 221, and the connecting part 222 can be mounted in the box body 27 of the high-voltage distribution box 20.

[0103] The embodiments of the present application can realize the mounting of the second busbar 22 on the high-voltage distribution box 20 through the connecting part 222, and the direction of the current flowing through the main body part 221 can be changed by setting at least part of the main body part 221 in a bent structure, thereby reducing the influence of the current generated by the second busbar 22 on the Hall sensor 21.

[0104] Optionally, as shown in Figure 5 and Figure 7 , the bent structure comprises at least two first plate bodies 2211 connected in sequence, and adjacent two first plate bodies 2211 are arranged at an angle.

[0105] Here, the number of the first plate bodies 2211 can be two, and the two first plate bodies 2211 are connected by the two connecting parts 222, and the two first plate bodies 2211 are arranged at an angle, at this time, the two first plate bodies 2211 can form a V-shaped structure or an asymmetric V-shaped structure, and of course, the tip of the V-shaped structure can adopt a sharp corner structure or a smooth transition structure.

[0106] The embodiments of the present application can change the flowing direction of the current flowing through the second busbar 22 through the at least two first plate bodies 2211 arranged at an angle, so that the structure is simple and easy to process.
