Recently, Jiyue 01, the first luxury intelligent pure electric SUV under Jiyue, successfully completed the vehicle thermal diffusion test, that is, the vehicle fire test, at the China Merchants Testing Vehicle Technology Research Institute. With the industry-leading thermal diffusion protection technology of the battery pack, no open flame was generated in the battery heating test for more than 1 hour, and the automotive robot successfully challenged the "extreme flame test". This is also the industry's first smart car without door handles to pass the vehicle fire test.
The vehicle-level thermal diffusion test is a mandatory test item in the European Union, and it is also a safety verification project that is being strengthened and popularized in China. Compared with the battery thermal runaway test, the vehicle-level test can evaluate the scenario of spontaneous combustion caused by simultaneous thermal runaway of multiple cells due to bottom scraping and collision, verify the vehicle's thermal safety protection capability from the vehicle level, and comprehensively test the protection ability of intelligent design for battery safety and occupants.
The patent of the core "firewall" prevents the occurrence of accidents.
As a luxury intelligent pure electric SUV model, Jiyue 01 inherits the excellent safety genes of SEA's vast architecture, and embodies a full range of protection ideas and innovative technologies in battery safety design. Based on this, through the application of independent patented technology "barrier-free exhaust", Jiyue has further effectively reduced the risk of thermal diffusion between battery cells, which is the most likely to detonate.
In this vehicle thermal diffusion test, when the battery is continuously heated to 700 degrees from the outside, the aerogel and basalt insulation materials between the cells will form a thermal barrier between the cells, blocking the diffusion of heat conduction between the cells. According to the test video records, even if a single cell is heated out of control, the heat will not spread to the adjacent cells.
When the difficulty of the test is further increased, after heating multiple cells to a thermal runaway state, Jiyue 01 opens the explosion-proof valve in time to vent the air, release the heat and open the water cycle to cool down the battery. At the same time, in view of the high-voltage arcing phenomenon that is most likely to cause fire hazards, the Jiyue 01 battery pack adopts a patented design of thermoelectric separation, which allows conductive substances to be quickly discharged from the battery pack, and is equipped with mica paper insulation material to strengthen insulation and thermal insulation protection.
At the same time, once the abnormal temperature of the battery cell and the high temperature fault occurs, the vehicle controller VCU of Jiyue 01 will cut off the high-voltage circuit in milliseconds, eliminate the risk of electric shock, ensure that the battery pack does not burn, do not burn, minimize the accident hazard, and provide enough time for users to get rid of safety risks.
BMS intelligent butler is linked to SIMO, and high-energy early warning protects personal safety inside and outside the car.
Jiyue 01 has the intelligent ability of the current industry. For smart cars, forward-looking design is not only about functional innovation and intelligent experience, but also about serving the safety of the whole vehicle. With the leading neural network linkage BMS battery intelligent management system of the whole car, SIMO turned on the alarm at the first time when thermal runaway occurred, and there was no open flame in the observation for up to 1 hour, which is significantly better than the national standard of "** alarm in the first 5 minutes".
When the BMS battery management system senses an abnormal cell temperature, SIMO will issue a fault warning through voice broadcast and large-screen information warning to inform the current vehicle status of the abnormality, regardless of whether the vehicle is driving, charging, or parking. The system will also quickly cut off the high-voltage power transmission to protect the personal safety of people inside and outside the vehicle, and if it is in the driving state, it will take power off measures after the vehicle pulls over.
When the battery continues to heat up to a thermal runaway state, a red sound and light alarm will be issued through the integrated large screen and voice in the car, and the double flash will start outside the car to remind the user and nearby personnel to stay away from the vehicle. The alarm information will also be sent to the cloud big data platform synchronously, and the emergency safety team and after-sales personnel will go to the scene of the accident to participate in the rescue as soon as possible after receiving the prompt.
Challenge the industry's first fire experiment of a smart car without a door handle, and unlock the door to escape as soon as possible.
Jiyue 01 adopts an innovative handleless electric induction door design, which can control the door opening and closing by automatic sensing and voice interaction, which not only improves the intelligent experience and styling design beauty, but also does not compromise on safety.
The handleless electric induction door is equipped with 4 millimeter-wave radars, which are more accurate than ultrasonic radars, more sensitive to obstacle avoidance, and are not afraid of bumps and "open the door to kill". The first independent redundant power supply system specially equipped for the electric door can still supply power to the door even in the extremely rare situation of a whole vehicle power failure, and the window will automatically lower 15s after the collision to facilitate rescue. The 4 interior door panels retain 4 mechanical handles as a contingency and can be unlocked with a single pull.
In the industry's first fire test without door handles in this challenge, the performance of the electric door emergency function of the Jiyue 01 is still very stable. After the vehicle is powered off, the dormant spare battery of Jiyue 01 can quickly intervene in the work, continuously supply power to the handleless induction electric door, unlock the door and open the escape channel at the first time, fully ensuring the safety of drivers and passengers. At the same time, rescuers from outside the vehicle can also open the door via the buttons on the B-pillar and C-pillar.
At present, the first mass-produced model of the Jiyue brand, the Jiyue 01, has been officially launched and delivered on October 27, based on the comprehensive empowerment of Geely Holding Group, Jiyue 01 has excellent technical strength, top car-making technology, the world's leading AI model, SEA vast architecture and other ecological capabilities.
