A battery module is an electrochemical device that needs to be regularly and necessarily charged and discharged for operation and maintenance to ensure its operating performance. Tens of thousands of large-scale batteries in the energy storage power station have brought heavy operation, detection and maintenance work.

[0003] At present, the detection of traditional energy storage power stations generally adopts on-site manual operation. The general steps are as follows: removing the battery from the energy storage container and taking it offline, using additional power source and energy equipment in the offline environment outside the container to perform one or more deep charge and discharge operations on the battery, recording the battery status and collecting data as the basis for detection and judgment. At the same time, after the detection and maintenance, the battery energy needs to be replayed to a certain state of charge before the battery can be reinstalled into the energy storage container. There is a need to develop an energy-saving and portable device for on-site use in energy storage stations for daily operation detection of batteries. For example, the Chinese invention patent with the publication number CN106124995A discloses a battery power detection device and a mobile electronic device; wherein, the battery power detection device includes a plurality of voltage sampling circuits, a plurality of voltage comparison circuits, and a power calculation circuit.

Through the battery power detection device of this patent, the detection of battery charge and discharge is realized. However, the device has a complex structure. After the battery is discharged, if the detected battery is qualified, it needs to be charged before it can be used. Additional temporary energy is required, and it is generally difficult for energy storage stations to connect temporary electricity to the test site, which is very inconvenient. During the discharge process, a resistive load is generally used, and through the form of heat dissipation, the power consumption is increased. The number of battery detection positions is small, even only one, and the detection efficiency is low, consuming a lot of time. Summary of the Utility Model

[0031] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0032] In the present utility model, descriptions involving "first", "second", "upper", "lower", etc. are only for descriptive purposes and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", "upper", "lower" may explicitly or implicitly include at least one such feature. Additionally, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the technical solutions between embodiments can be combined and implemented, they are all within the protection scope required by the present utility model.

[0033] The following will detail the present utility model with reference to the accompanying drawings and in combination with embodiments.

[0034] As Figures 1 to 3 shown, a mobile on-site battery detection device includes: a battery detection device 100, a detection control device 500, and a carrier 300. The battery detection device 100 includes: a battery accommodation position 110, a bidirectional power supply 200, and a switching mechanism (not shown in the figure). A plurality of battery accommodation positions 110 are provided for accommodating rechargeable batteries 600 to be detected. The bidirectional power supply 200 is electrically connected to the rechargeable battery 600. The bidirectional power supply 200 and the rechargeable battery 600 are electrically connected through the switching mechanism, and the current direction between the bidirectional power supply 200 and the rechargeable battery 600 is switched through the switching mechanism. The detection control device 500 is electrically connected to the rechargeable battery 600. The battery detection device 100 is disposed on the carrier 300, and the carrier 300 is movable.

[0035] The battery detection device 100 can be transported to the site for battery detection at any time through the movable carrier 300. The battery detection device 100 includes a plurality of battery accommodation positions 110, and can detect a plurality of rechargeable batteries 600 simultaneously, improving the detection efficiency. A bidirectional power supply 200 is provided, which can be charged and discharged without relying on an external power supply, saving energy. It does not need to discharge through a load such as a resistor. The bidirectional power supply 200 and the rechargeable battery 600 to be measured can be "source and load" to each other. Compared with discharging through other loads, the power energy consumption is reduced. Except for the consumption such as heat generation during testing, the energy of the bidirectional power supply 200 can be reused. A switching mechanism is provided to change the current direction according to the detection requirements and switch between charging and discharging of the rechargeable battery to be measured. Preferably, the switching mechanism uses a controllable bidirectional AC switch. During testing, the detection control device 500 is electrically connected to the rechargeable battery 600 to be measured, receives the voltage change during charging and discharging, obtains the performance information of the rechargeable battery 600 to be measured, and checks whether it is qualified. If the detection result is not within the predetermined monitoring standard range, it is determined that the rechargeable battery 600 is scrapped.

[0036] Furthermore, the bidirectional power supply 200 is a detachable rechargeable battery.

[0037] When the battery power is insufficient, it is convenient to replace. During detection, the rechargeable battery 600 to be monitored can be set at the battery accommodation position 110 with convenient operation, without carrying all the rechargeable batteries as the bidirectional power supply 200.

[0038] Furthermore, the bidirectional power supply 200 is a battery having the same parameters as the rechargeable battery 600 to be measured.

[0039] When it is detected that the rechargeable battery 600 to be detected has a fault and needs to be replaced, the bidirectional power supply 200 can be used as a backup battery and replaced at any time, reducing the transportation load and improving the on-site maintenance efficiency.

[0040] Furthermore, each battery accommodation position 110 is electrically connected to a bidirectional power supply 200 through a switching mechanism.

[0041] As an embodiment, the switching mechanism can be shared by multiple battery accommodation positions 100, and each battery accommodation position 100 is equipped with a switching mechanism, which can avoid operation errors and reduce energy loss due to too long busbars.

[0042] As an implementation manner, the switching mechanism can also implement circuit switching between different battery capacity positions. Through this implementation manner, when the bidirectional power supply 200 at a certain battery capacity position 110 has insufficient power, it can be charged by the bidirectional power supply 200 at other battery capacity positions 110, or even by the rechargeable battery 600 being detected. For the specific circuit design, those skilled in the art can design it according to the situation using existing technologies, and details will not be elaborated here.

[0043] Furthermore, the power supply capacity position 110 is in a box shape, and one side wall thereof is a cover plate 111 that is detachably connected to the box. The switching mechanism is arranged on the side wall opposite to the cover plate 111.

[0044] Furthermore, the cover plate 111 is rotatably connected to the top plate of the box. The cover plate 111 can be fixed to a preset position by a fixing device 112 when it is flipped towards the top plate.

[0045] In this embodiment, the cover plate 111 is flipped upwards to open and is fixed by the fixing device 112 after opening. The fixing device 112 can be a support rod, and the support rod can be slidably connected to the side wall of the box or can be arranged as a cylinder structure. After the cover plate 111 is fixed, it can be used for sunshading, rain shielding, etc., to avoid the influence of strong sunlight or rain on the battery during detection, which may affect the monitoring effect or even damage the battery and detection equipment. Through the battery detection equipment of the above embodiment, energy loss is reduced, detection is facilitated, the influence of strong sunlight and rain during the detection process is prevented, and the detection efficiency is improved.

[0046] Furthermore, the mobile on-site battery detection equipment further includes: an auxiliary power supply 400, which is electrically connected to the bidirectional power supply 200.

[0047] After a bidirectional power supply 200 has been detected multiple times and its power has been somewhat consumed, it can be charged by the auxiliary power supply 400.

[0048] Furthermore, the carrier table 300 is towed and moved by a driving mechanism (not shown in the figure).

[0049] Towing by the driving mechanism facilitates the movement of the carrier table 300. As a preferred manner, the carrier table 300 can be a vehicle.

[0050] As an implementation manner, the driving mechanism is an electric motor, and the auxiliary power supply 400 is a vehicle-mounted battery that supplies power to the driving mechanism.

[0051] The detection equipment can be transported to the site by an electric vehicle, which facilitates the transportation of the detection equipment, the bidirectional power supply, as well as other detection tools and personnel.

[0052] In this embodiment, the vehicle-mounted battery provides power for the electric vehicle to drive the electric vehicle to move. At the same time, the vehicle-mounted battery is electrically connected to the bidirectional power supply 200. During the detection process, when the bidirectional power supply 200 has insufficient power, it can be charged by the vehicle-mounted battery. During the movement of the vehicle, when the vehicle-mounted battery has insufficient power, the bidirectional power supply 200 can charge the vehicle-mounted battery. The bidirectional power supply 200 is used to detect the rechargeable battery 600 to be detected. After the detection, if it is determined that the rechargeable battery 600 to be detected is a qualified battery, the rechargeable battery 600 needs to be put back into the energy storage system for continued use. However, the detection may cause power consumption of the rechargeable battery 600. Therefore, before putting it back into the energy storage system, it is charged by the bidirectional power supply 200.

[0053] As described above, when the switching mechanism can achieve circuit switching of different battery accommodation positions 110, the rechargeable battery 600 with insufficient power can also be charged by other rechargeable batteries 600 to be detected, so that the power of all the rechargeable batteries 600 to be detected is the same. Then, the rechargeable battery 600 that has been detected and determined to be qualified is put back into the energy storage system.

[0054] By this embodiment, without an external power supply, the mutual energy transfer among the vehicle-mounted battery, the bidirectional power supply 200, the first rechargeable battery 600 to be detected, and the second rechargeable battery 600 is realized, and the mutual energy supplement and energy balance are achieved. Compared with the prior art that uses a resistor to discharge and detect the rechargeable battery 600 to be detected, the power loss of the rechargeable battery 600 is reduced. During the detection process, it is not necessary for the rechargeable battery 600 to be detected under a fully charged state. After the detection is completed, it is not necessary to be fully charged before being put back into the energy storage system. The power of the rechargeable battery 600 can be adjusted according to the state of charge of the energy storage system and then put back into the energy storage system, and is electrically connected to the energy storage system circuit.

[0055] As another embodiment, the driving mechanism further includes an engine, and the engine is electrically connected to the bidirectional power supply 200 through an energy conversion mechanism.

[0056] The vehicle can also be a fuel vehicle. During on-site detection, the energy generated by the engine can be converted into electrical energy through the energy converter mechanism and provided to the bidirectional power supply 200.

[0057] In addition, devices such as solar power generation and wind power generation can also be provided on the detection device to supply power to the bidirectional power supply 200 using solar energy or wind energy, etc.

[0058] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
