[0002] Intelligent driving essentially involves cognitive ergonomics of attention attraction and distraction, mainly including three links: network navigation, autonomous driving, and manual intervention. The prerequisite for intelligent driving is that the vehicle we choose meets the dynamic requirements of driving, the sensors on the vehicle can obtain relevant visual and auditory signals and information, and the corresponding follow-up system can be controlled through cognitive computing;

[0003] The power battery system is the most critical core component in new energy vehicles and can be compared to the heart of new energy vehicles. There is an inseparable internal relationship between the application performance of the power battery system during subsequent operation and the overall cruising range, charging and discharging speed, and driving safety of new energy vehicles.

[0004] There are two common causes of internal faults in new energy batteries. One is overcharging; the other is over-discharging. Both of these situations will produce a strong electrochemical reaction, resulting in a rapid increase in battery temperature and prone to problems such as fire or explosion. The external short circuit of new energy batteries is mainly due to the influence of external factors on the operation of the battery system. For example, when driving in rainy weather, after water enters the battery system, it will penetrate into the electrolyte, which is likely to cause problems such as electrolyte leakage or penetration, thus triggering the phenomenon of external short circuit of the battery. Therefore, we need to take preliminary precautions against the above-mentioned fault phenomena, regularly detect lithium batteries to prevent accidents. However, the existing fault detection devices only regularly detect lithium batteries and are difficult to achieve a preventive effect. Therefore, we need to design an intelligent driving fault detection device for an automobile to solve the above-mentioned problems. Content of the Utility Model

[0011] As a further description of the above technical solution, a protection plate is connected to the outside of the automobile battery fault detection box, and a protection pad is connected to the outside of the protection plate. A protection mechanism is arranged inside the protection pad, and there are three groups of the protection mechanisms.

[0025] Next, the present utility model will be further described in conjunction with the embodiments.

[0026] Embodiment 1:

[0027] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 6, including an automotive battery fault detection box 1.

The fans 1303 are connected to each other through the pulley 1304. On both sides inside the automotive battery fault detection box 1 are respectively connected to an air extraction port 5 and an air inlet 7. Inside the automotive battery fault detection box 1 at the bottom end of the air extraction port 5 is connected to a PID detector 14, and inside the automotive battery fault detection box 1 at the bottom end of the air inlet 7 is connected to a single-chip microcomputer 16. The top of the explosion-proof warning box 11 is connected to an alarm 12. The output end of the PID detector 14 is electrically connected to the input end of the single-chip microcomputer 16 through a wire, and the output end of the single-chip microcomputer 16 is electrically connected to the input end of the alarm 12 through a wire.

[0028] In this embodiment, during use, when the temperature generated by the lithium battery body 4 is too high, the heat will fill and expand the airbag 1306, which will then touch and squeeze the touch sensor 1302. The touch sensor 1302 receives the signal and transmits it to the single-chip microcomputer 16.
