In order to make the battery have good performance in the practical use process, the battery often needs to be subjected to various performance tests before being put into practical use and produced. However, it is often difficult for a laboratory environment to simulate the state of the battery mounted on an actual vehicle, and the test results obtained in the laboratory environment may deviate from the conditions of the battery during actual use. Therefore, how to obtain more accurate performance test data is still a problem to be solved.

In view of this, the present application provides a battery testing device in which a first fixing member is capable of connecting a battery and a hanging member in a manner of penetrating a mounting member of the battery, and the hanging member can hang the battery on a supporting structure to simulate a scene in which the battery is mounted on an electric device, for example, a scene in which the battery is mounted on a chassis of a vehicle. The performance test is carried out on the battery under the scene, so that the test result is more similar to the performance of the battery under the actual use scene, and the accuracy of the performance test is improved.

The technical scheme described in the embodiment of the application is applicable to various electric equipment using batteries. The electric equipment can be vehicles, mobile phones, portable equipment, notebook computers, ships, spacecrafts, electric toys, electric tools and the like. The vehicle can be a fuel oil vehicle, a fuel gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle or a range-extended vehicle; spacecraft including airplanes, rockets, space planes, spacecraft, and the like; the electric toy includes fixed or mobile electric toys, such as a game machine, an electric car toy, an electric ship toy, and an electric airplane toy; power tools include metal cutting power tools, grinding power tools, assembly power tools, and railroad power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete shakers, and electric planers, among others. The embodiment of the application does not limit the electric equipment in particular.

For convenience of explanation, the following embodiments take electric equipment as an example of a vehicle.

For example, as shown in fig. 1, for a schematic structural diagram of a vehicle 1 provided in an embodiment of the present application, the vehicle 1 may be a fuel-oil vehicle, a gas-fired vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid electric vehicle or an extended range vehicle. The vehicle 1 may be provided with a motor 40, a controller 30 and a battery 10, the controller 30 being arranged to control the battery 10 to supply power to the motor 40. For example, the battery 10 may be provided at the bottom or the head or the tail of the vehicle 1. The battery 10 may be used for power supply of the vehicle 1, e.g. the battery 10 may be used as an operating power source for the vehicle 1, for electrical circuitry of the vehicle 1, e.g. for start-up, navigation and operational power requirements of the vehicle 1. In another embodiment of the present application, the battery 10 may not only serve as an operating power source for the vehicle 1, but also as a driving power source for the vehicle 1, instead of or in part instead of fuel oil or natural gas, to provide driving power for the vehicle 1.

To meet different power requirements, the battery may include a plurality of battery cells, where the plurality of battery cells may be connected in series or parallel or a series-parallel connection, and the series-parallel connection refers to a mixture of series and parallel connection. The battery may also be referred to as a battery pack. Optionally, the plurality of battery cells may be connected in series or parallel or in series-parallel to form a battery module, and then the plurality of battery modules are connected in series or parallel or in series-parallel to form a battery. That is, a plurality of battery cells may be directly assembled into a battery, or may be assembled into a battery module first, and the battery module may be assembled into a battery.

For example, fig. 2 illustrates a schematic structure of a battery 10 according to one embodiment of the present application, and the battery 10 may include at least one battery module 200. The battery module 200 includes a plurality of battery cells 20. The battery 10 may further include a case 11, in which the case 11 has a hollow structure, and the plurality of battery cells 20 are accommodated in the case 11. Fig. 2 illustrates one possible implementation of the case 11 according to the embodiment of the present application, and as shown in fig. 2, the case 11 may include two parts, which are referred to herein as a first case portion 111 and a second case portion 112, respectively, and the first case portion 111 and the second case portion 112 are fastened together. The shape of the first and second case parts 111 and 112 may be determined according to the combined shape of the battery modules 200, at least one of the first and second case parts 111 and 112 having one opening. For example, as shown in fig. 2, each of the first case portion 111 and the second case portion 112 may be a hollow rectangular parallelepiped and only one surface thereof is an open surface, the opening of the first case portion 111 and the opening of the second case portion 112 are disposed opposite to each other, and the first case portion 111 and the second case portion 112 are engaged with each other to form the case 11 having a closed chamber.

As another example, unlike the one shown in fig. 2, only one of the first and second case parts 111 and 112 may be a hollow rectangular parallelepiped having an opening, and the other may be a plate-like shape to cover the opening. For example, here, the second case portion 112 is a hollow rectangular parallelepiped and only one face is an opening face, and the first case portion 111 is a plate-like shape, and then the first case portion 111 is covered at the opening of the second case portion 112 to form a case 11 having a closed chamber that can be used to house a plurality of battery cells 20. The plurality of battery cells 20 are connected in parallel or in series-parallel, and then are placed in the box 11 formed by buckling the first box 111 and the second box 112.

Alternatively, the battery 10 may further include other structures, which are not described in detail herein. For example, the battery 10 may further include a bus member for making electrical connection between the plurality of battery cells 20, such as parallel or series-parallel connection. Specifically, the bus member may realize electrical connection between the battery cells 20 by connecting electrode terminals of the battery cells 20. Further, the bus member may be fixed to the electrode terminals of the battery cells 20 by welding. The electric power of the plurality of battery cells 20 may be further led out through the case 11 by the conductive mechanism.

The number of battery cells 20 in the battery module 200 may be set to any value according to different power requirements. The plurality of battery cells 20 may be connected in series, parallel, or series-parallel to achieve a larger capacity or power. Since the number of battery cells 20 included in each battery 10 may be large, the battery cells 20 are arranged in groups for easy installation, and each group of battery cells 20 constitutes the battery module 200. The number of battery cells 20 included in the battery module 200 is not limited, and may be set according to requirements.

The battery 10 may include a plurality of battery modules 200, and the battery modules 200 may be connected in series, parallel, or series-parallel.

The battery testing device 300 can simulate the state of the battery 10 to be tested mounted on the vehicle by adjusting the distance between the suspension 320 and the ground, and test the battery 10 to be tested in the state, so that the testing environment is closer to the actual use environment of the battery 10 to be tested, thereby being beneficial to improving the accuracy of the testing result.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
