[0001] The present invention relates to the technical field of PCTC ship roll-on / roll-off transport of new energy vehicles, and in particular to a method and system for monitoring battery status during the process of PCTC ship transporting new energy vehicles. Background Art

[0002] In recent years, the new energy vehicle industry has flourished, and electric vehicles are one of the main types of new energy vehicles. With the growth of electric vehicle production, PCTC roll-on / roll-off transportation, as a key link in its logistics, has received more attention. Due to the particularity of the nature of the cargo transported by PCTC ships and their construction design, accidents are very likely to cause casualties and serious economic losses. Therefore, the safety supervision of PCTC ships and their cargo is extremely important. Compared with traditional oil vehicles, new energy vehicles have higher safety risks in terms of batteries, electronic control systems, etc. Therefore, how to ensure the safety of automobile batteries during long-distance and long-term roll-on / roll-off transportation is an urgent problem that needs to be solved.

[0003] Existing new energy vehicle status monitoring technologies and solutions mainly monitor the battery status by detecting battery power, voltage, current, temperature and other status information based on the on-board battery management system (BMS) when the vehicle is powered, which is suitable for regular driving and short-term parking scenarios. However, during long-distance and long-term roll-on / roll-off transportation, new energy vehicles will "power off", that is, cut off all power supply and no longer output any status information, which is equivalent to entering a silent state. In this case, existing technologies and solutions cannot continue to monitor the battery status.

[0004] In view of the above problems, the present invention aims to design a battery status monitoring method and system during the PCTC ship carrying new energy vehicles, so as to solve the problem of vehicle battery status monitoring after the new energy vehicles are powered off during roll-on / roll-off transportation.

[0031] Specifically, firstly, the set thresholds corresponding to the various data collected of the new energy vehicle battery are obtained; then, it is determined whether the collected data of the new energy vehicle battery exceeds the corresponding set thresholds; if so, it is determined that the state of the new energy vehicle battery is abnormal, and then step 103 is executed; if not, it is determined that the state of the new energy vehicle battery is normal, wherein the set thresholds are manually set in advance;

[0032] In addition, according to the changing trend of the continuously collected new energy vehicle battery data, it is determined whether the collected new energy vehicle battery data is in a frequently changing state; if so, it is confirmed that the state of the new energy vehicle battery is abnormal, and then step 103 is executed; if not, the state of the new energy vehicle battery is normal.

[0033] Step 103: If it is confirmed that the state of the new energy vehicle battery is abnormal, an alarm prompt message is issued.

[0034] In this embodiment, when the state of the new energy vehicle battery is confirmed to be abnormal, the crew can be promptly notified through sound and light alarms, so that the state of the new energy vehicle battery can be monitored in real time to ensure the safety of the new energy vehicle battery.

[0035] The second embodiment of the present invention relates to a battery status monitoring system during the PCTC ship carrying new energy vehicles, see Figure 2 and Figure 3 , specifically composed of three parts: vehicle-side equipment, ship-side equipment and shore-side equipment.
