[0019] Example 1

[0020] like Figure 1 As shown, a power battery anti-theft monitoring system for new energy vehicles includes a power battery control management system, an intelligent network controller, a body control domain, an intelligent cloud control platform and a mobile terminal; the intelligent network controller is respectively connected to the power battery control management system, the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform is connected to the mobile terminal;

[0021] The power battery control and management system is used to monitor the power battery status signal and send the power battery status signal to the intelligent network controller. The intelligent network controller determines whether the power battery is in an abnormal state based on the power battery status signal. If not, it sends a normal signal to the body control domain and the intelligent cloud control platform. If so, it sends an alarm signal to the body control domain and the intelligent cloud control platform. The intelligent cloud control platform sends power battery alarm information to the mobile terminal based on the alarm signal. Among them, the power battery status signal is the grounding harness status of the vehicle power battery shell. When the intelligent network controller detects that the grounding harness end loop of the power battery shell is disconnected, the power battery is in an abnormal state. Preferably, all communication network signals such as 4G / 5G are used between the intelligent network controller and the intelligent cloud control platform. The mobile terminal can remind users through all network artificial intelligence methods such as text messages, phone calls and APP prompts.

[0022] Also includes a backup power module;

[0023] When the vehicle is turned off and the intelligent network controller is in a dormant state, the backup power module continues to supply power to the intelligent network controller. Preferably, the backup power module is built into the intelligent network controller, or it can be used as an independent vehicle backup power module, which is turned off during normal operation of the vehicle and pre-charged through the power battery system. Use.

[0025] A method for monitoring the anti-theft of a power battery of a new energy vehicle, wherein an intelligent network connection controller determines whether the power battery is in an abnormal state according to a power battery status signal, and the determination method is based on a safety authentication algorithm and includes:

[0026] The power battery control and management system sends a first random number key to the intelligent network controller, and the intelligent network controller sends a second random number key to the power battery control and management system; it is determined whether the first random number key and the second random number key are equal. If they are equal, the security authentication is passed, that is, the power battery is in a normal state; if they are not equal, the security authentication fails, that is, the power battery is in an abnormal state.

[0027] The intelligent network controller receives the power battery status signal in real time at intervals and stores the power battery status signal. Specifically, the intelligent network controller receives the power battery status signal in real time every 1 hour and stores the power battery status signal inside the intelligent network controller for easy access and viewing.

[0028] When the power battery status abnormality lasts for more than the set time A, the intelligent network controller sends a first-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends power battery anti-theft warning information to the mobile terminal according to the first-level alarm signal. Specifically, when the power battery status abnormality lasts for more than 5s, the intelligent cloud control platform sends a first-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends power battery anti-theft warning information to the mobile terminal according to the first-level alarm signal.

[0029] When the number of intermittent power battery status abnormalities exceeds the set number within the set time B, the intelligent network controller sends a second-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends power battery anti-theft abnormality information to the mobile terminal according to the second-level alarm signal. Specifically, when the number of intermittent power battery status abnormalities exceeds 5 times within 3 minutes, the intelligent cloud control platform sends a second-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends power battery anti-theft abnormality information to the mobile terminal according to the second-level alarm signal.

[0030] When the power battery status abnormality lasts for more than the set time C, the intelligent network controller sends a third-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends the power battery theft information to the mobile terminal according to the third-level alarm signal. Specifically, when the power battery status abnormality lasts for more than 3 minutes, the intelligent network controller sends a third-level alarm signal to the body control domain and the intelligent cloud control platform, and the intelligent cloud control platform sends the power battery theft information to the mobile terminal according to the third-level alarm signal.

[0031] The third level alarm signal takes precedence over the second level alarm signal, and the second level alarm signal takes precedence over the first level alarm signal; the display status of the mobile terminal is based on the highest alarm level of this time and is irreversible until the alarm is lifted.
