AutoBeta(AutoBeta.net)11/21 Report--

Recently, it has been reported that NIO submitted a patent on the self-destruct system of electric vehicles to the US Patent Office, and the US Patent and Trademark Office said that the patent is how NIO electric vehicles use their own batteries to end their lives, but this is actually a safety function that can prevent catastrophic battery failures from killing people.

According to the patent document, in-car sensors and computer programs can alert passengers when they detect and determine that the vehicle is about to suffer from irreparable conditions such as battery thermal runaway and widespread failure of the power management system. the autopilot program then drives to an unmanned safe zone away from the building and nearby with water. To put it simply, when the vehicle is out of control, it can remind passengers to get off and go to the "self-destruct" site on their own.

In addition, the patent also takes into account that in the event of a devastating failure during the charging process, the car can automatically "spit out" the charging plug and drive away quickly. If the garage door is closed, you can rush out of the garage door by yourself. Or if the car of a car owner with travel restrictions has such a failure, he can get evacuation help and provide help by warning pedestrians nearby through external information.

However, the introduction of this patent is entirely based on self-driving scenarios, while in the current environment, it can not be fully applied to real cars. But the starting point of the patent is based on advanced representatives, so that damage can be minimized if the vehicle automatically leaves the crowd and around the building before causing a devastating disaster.

Since the launch of the new car, its ES8 has had four incidents of spontaneous combustion, and then it has also conducted a comprehensive recall of the problem vehicles, a total of 4803 vehicles. Battery packs with NEV-P102 modules will be replaced free of charge for all recalled vehicles to eliminate the above safety risks.

Of course, the spontaneous combustion of new energy vehicles is not only a problem of Lulai cars. In August 2019, the National big data Alliance of New Energy vehicles released the Safety Supervision Achievement report of big data, the national regulatory platform for new energy vehicles. Data show that since May this year, the national regulatory platform for new energy vehicles has found a total of 79 safety accidents, involving 96 vehicles. Of the vehicles that have identified the cause of the fire, 41% are in a driving state, 40% are at rest, and 19% are in a charging state.

The vast majority of accident vehicles use ternary lithium batteries, accounting for 86%. Among the causes of fire, 58% of the vehicle fires are caused by battery problems, 19% of the vehicle fires are caused by collision problems, and some vehicles are caused by flooding, parts failure, use problems and other reasons. It means that there is still a lot of room for improvement in new energy sources.

In this regard, many netizens complained about this function: "it is better to solve the most basic problems before making new inventions." Indeed, today's impact on the development of new energy vehicles in addition to national compensation, but also consumers are still worried about the current technology of new energy vehicles.

However, the patent is only based on an assumption that it applies only if the developed vehicle is fully self-driving. Even if the self-driving technology of today's "smart" cars reaches the standard of road testing, there are still many hidden dangers.
