[0002] For battery cabinet batteries used in ships, conventional battery detection systems cannot cover all aspects of the battery replacement process.

[0003] In the ship battery replacement application scenario, the battery will go through the following complex operation process, including lifting the battery from the onshore battery replacement station through a lifting device - lifting it to the designated transfer point on the ship - moving it along the guide rail from the transfer point to the fixed point in the container. During this series of processes, the battery may be affected by unexpected situations such as collision, damage or tilt, resulting in its performance degradation or failure.

[0004] In order to ensure the normal performance of the battery before it is put into use, a comprehensive and careful inspection must be carried out before it is put into use.

[0051] The embodiments of the present invention will be described in more detail below by way of examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0052] In a specific embodiment, Figure 1 As shown, a battery detection system for a replaceable power battery cabinet for new energy ships includes a control system 1, a current sensor 2, a test power supply 3, a battery cabinet, a discharge load 4, an intelligent circuit breaker 5, a connection line system, an image acquisition device and a sensor system.

[0053] A number of batteries are arranged in the battery cabinet.

[0054] The connecting line system comprises a first connecting line 6 and a second connecting line 7 .

[0055] The first connecting line 6 includes a main line and a plurality of branch lines.

[0056] The second connecting line 7 is a load line.

[0057] One end of a plurality of branch lines is integrated and connected to one end of a main line, and the other end is respectively connected to a plurality of batteries in a battery box cabinet.

[0058] The main line is connected to the current sensor 2.

[0059] The load line is used to connect the battery cabinet and the discharge load 4.

[0060] The image acquisition device is used to acquire image information of the outer surface of the battery and transmit it to the control system 1 .

[0061] The sensor system is used to collect the operating environment information of the battery cabinet and transmit it to the control system 1.

[0062] The intelligent circuit breaker 5 is arranged on the power supply line connecting the battery cabinet and the marine system. It should be noted that, since the main innovation of the present invention lies in the battery detection system, the specific installation position of the intelligent circuit breaker 5 can be set at different positions according to the needs of different ships. The present invention only proposes the concept of technical principle, so the power supply line connected to the marine system is not shown, but those skilled in the art can know how to set it according to the common sense and known technology in the field.

[0063] The test power supply 3 is used for supplying power during battery detection.

[0064] In this embodiment, the image acquisition device includes a plurality of high-definition cameras 8; the plurality of high-definition cameras 8 are arranged around the inner and outer surfaces of the battery cabinet. The high-definition cameras 8 inside the battery cabinet are used to collect the appearance information of the batteries inside the battery cabinet, and the high-definition cameras outside the battery cabinet are used to collect the appearance information of the surface of the battery cabinet, such as whether there are cracks on the outer surface of the battery cabinet, etc.

[0065] In this embodiment, the sensing system includes a water immersion sensor 9 and a temperature and humidity sensor 10 .

[0066] The water immersion sensors 9 are arranged on the bottom surface of the battery cabinet, and the number thereof can be freely selected according to the size of the battery cabinet. The temperature and humidity sensors 10 are evenly distributed in the battery cabinet.

[0067] In this embodiment, the test power source 3 is a battery.

[0068] The temperature and humidity sensor 10 is used to detect whether the temperature and humidity of the battery operating environment exceed the limit, the water immersion sensor 9 is used to detect whether water accumulates in the battery cabinet, and the high-definition camera 8 is used to visually identify whether the battery pack (battery system or other common names) and the appearance of the battery cabinet are abnormal.

[0069] In this embodiment, the test power supply 3 is used to supply power to the detection system. When the line between the battery pack and the ship system is closed, the test power supply 3 starts to work.

[0070] like Figure 2 As shown, the specific operation process of this embodiment is as follows:

[0071] S1, manually or mechanically fix the ship's power battery cabinet to the designated position and turn on the battery detection system.

[0072] S2, the control system 1 sends a detection instruction to the sensor system, and the sensor system detects whether the operating environment of the battery cabinet is normal; it should be noted that this step continues to detect after the battery cabinet is in place, that is, S2 is always in execution before the detection is completed.

[0073] If the operating environment is normal, the control system 1 runs to S3, otherwise it enters S6.

[0074] S3, control system 1 sends a detection instruction to the image acquisition device; the image acquisition device collects the appearance image information of the battery cabinet and the appearance image information of the batteries inside the battery cabinet and transmits it to the control system 1; the control system 1 determines whether the appearance of the battery cabinet and the batteries is normal, and the detection content includes scratches, damage, deformation, cracks, etc.; if normal, proceed to S4, otherwise enter S6.

[0075] Similar to S2, this step continues to detect after the battery cabinet is in place, that is, S3 is always in execution when the detection is not completed. In addition, this step also includes detecting the indicator light status of the battery cabinet. When the green light is on, it proves that the detection system is normal. When the red light is on, it proves that there is a fault in the detection link. Once the indicator light turns red, S6 will be entered. The indicator light is set in the battery cabinet and can be photographed by at least one high-definition camera 8.

[0076] S4, the control system 1 enters the battery performance test mode, and the intelligent charge and discharge test control software in the control system 1 starts the test. It should be noted that the intelligent charge and discharge test control software is not a unique technology of the present invention. The present invention merely integrates the software on the market. Therefore, the specific functional components of the intelligent charge and discharge test control software are not elaborated in detail. Those skilled in the art should know the specific functional components of the intelligent charge and discharge test control software and how to implement it (prior art).

[0077] S4.1, the control system 1 cuts off the intelligent circuit breaker 5 and turns on the test power supply 3.

[0078] S4.2, testing the performance parameters of all batteries, as shown below;

[0079] (1) Detect the number of battery strings;

[0080] (2) Detecting battery voltage;

[0081] (3) Detect battery system temperature;

[0082] (4) Insulation testing;

[0083] (5) Self-test of PCBA components such as eeprom, flash, afe, etc.

[0084] If the performance parameters of all batteries are normal, proceed to S4.3, otherwise proceed to S6.

[0085] S4.3, the battery performance test is completed, the test power supply 3 is turned off, and the intelligent circuit breaker 5 (also known as the main line intelligent switch) is closed.

[0086] After the battery performance test is completed, if the performance of all batteries is normal, the process proceeds to S5, otherwise, the process proceeds to S6.

[0087] S5: All batteries meet the operating requirements and the battery cabinet BMS is put into normal operation.

[0088] S6, control system 1 alarms and displays the alarm information on the control screen for manual investigation.

[0089] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
