On June 24, the Geely Galaxy Starship 7 EM-i was at the China Automobile CenterNew energyThe inspection center completed the industry’s first “gasoline and electricity stabbing” test, becoming the world’s first plug-in hybrid model to pass the synchronous puncture test of power battery and fuel tank. This test not only refreshed the safety standards of plug-in hybrid models, but also demonstrated Geely’s leading strength in the field of new energy safety with strict conditions that far exceeded national standards.
The industry’s first “oil and electricity thorn” test was successfully passed, and the safety standards far exceeded the new national standard
This test refers to the latestElectric vehicleThe safety requirements for power batteries (hereinafter referred to as the new national standard) are an enhanced version of the battery needle puncture trigger thermal runaway test, and it is also the first time in the industry that the “battery + fuel tank” puncture test has been completed for plug-in hybrid models. The test simulates the extreme working conditions of the vehicle being pierced by road bumps or sharp obstacles (such as steel bars, broken metal parts, etc.) at the same time, and verifies the safety of the Geely Galaxy Starship 7 EM-i in extreme scenarios.
According to the requirements of the new national standard, the thermal runaway of a single cell can be triggered by needle puncture to carry out thermal diffusion tests. The test used multiple steel needles to pierce the power battery and fuel tank of the Geely Galaxy Starship 7 EM-i at the same time. thereinto4 pierced power batteries, 2 pierced the fuel tank, artificially caused battery short circuit + fuel tank leakage at the same time, so that the battery and fuel tank were damaged at the same time, more damage points, the risk of heat diffusion was intensified, and the test was difficult。
The test results show that:Geely Galaxy Starship 7 EM-i Under extreme damage conditions, the battery pack still does not catch fire or explode, and the risk of thermal runaway is controllable.High safety, fully verifying that the Aegis battery safety system equipped with Geely Galaxy Starship 7 EM-i far exceeds the safety strength of the national standard, eliminating users’ dual concerns about the “oil and electricity safety” of the battery and fuel system of plug-in hybrid models.
Previously, the Aegis battery safety system equipped with the Geely Galaxy Starship 7 EM-i has passed a number of extreme tests, such as 8-needle stabbing, real bullet shooting, medium and high-speed bottom collision test, etc., and the battery pack has passed 6 strict “devil” serial tests of the China Automobile Center, verifying its battery safety performance beyond industry standards under extreme working conditions. This time, the Geely Galaxy Starship 7EM-i successfully challenged the industry’s first “gasoline-electric thorn” test, once again proving with the strength of safety standards that far exceed the “new national standard”: safety is the gene engraved in the bones of Geely Galaxy, and the Geely Galaxy Starship 7 EM-i leads the A-class plug-in hybrid SUV into a new generation of safety.
Native GEA architecture + Aegis battery safety system, oil-electricity symbiosis is more harmonious
For a long time, new energy plug-in hybrid models have been widely sought after by the market with the advantages of oil, electricity, and no mileage anxiety. According to data from the Passenger Association, the sales growth rate of plug-in hybrid models in China will reach 80% in 2024, becoming one of the fastest growing market segments for new energy. At the same time, users are paying more attention to the safety of plug-in hybrid models’ power batteries and fuel systems.
As Geely Galaxy’s first plug-in hybrid SUV based on GEA’s exclusive new energy architecture, the Geely Galaxy Starship 7 EM-i has adhered to Geely’s car-making concept of “safety is the first priority” from the beginning of its design. Fully considering the linkage relationship between the two major systems of oil and electricity, the innovative safety concept of “oil-electricity symbiosis” has realized the original design of “physical isolation of oil and electricity”, exclusive structural protection, and ladder layout, which solves the “double hidden dangers” of gasoline and electricity safety of plug-in hybrid models from the root.
Among them, the physical isolation of oil and electricity is to separate oil and electricity: the oil circuit, high-voltage line, exhaust pipe, fuel filler, and charging port have an independent and exclusive channel design to avoid direct contact with each other, achieve high temperature, high voltage does not interfere, and the symbiosis of oil and electricity is more harmonious, greatly reducing potential safety hazards. At the same time, Geely Galaxy Starship 7 EM-i pioneered the “6 horizontal and 4 vertical safes” 360-degree 6-ring full-dimensional protection, which can effectively guide and disperse to the frame structure when collisions occur in all directions, and at the same time protect the battery pack and fuel tank from impact damage through the collapse of the ring structure. In addition, the Geely Galaxy Starship 7EM-i innovatively adopts a three-layer stepped protection design, from the ultra-high-strength protective beam of the subframe, to the sandwich protection of the bottom of the battery, and then to the three-layer stepped bottom scraping protection of the high-pressure fuel tank, so as to achieve the ultimate protection of the external structure of the fuel tank and battery pack. In the event of a serious collision, the arc can be cut off within 50 milliseconds, effectively avoiding the risk of oil circuit fire caused by circuit sparks.
Geely Galaxy Starship 7 EM-i industry’s unique “six horizontal and four vertical” gasoline-electric safe cabin design, through six beams and four longitudinal beams, forms a frame structure, which can effectively disperse and guide the impact force of front, rear and side collisions, and avoid the serious impact of single-point concentrated force on the body, battery pack and fuel tank. The 360-degree collision 6-ring full-dimensional protection uses the front, side and rear 360-degree protective ring structure, which effectively guides and disperses the impact force to the frame structure when collisions occur in all directions, and at the same time protects the battery pack and fuel tank from impact damage through the collapse and energy absorption of the ring structure.
In terms of battery, the Aegis battery safety system equipped with Geely Galaxy Starship 7 EM-i has undergone 100+ full-scenario extreme working condition tests, which not only pays attention to battery cell safety, but also integrates architecture, vehicle, intelligent control, and cloud, and a “no blind spot” battery safety system. Among them, the battery cell adopts safety materials such as wet double-coated separator and high-safety electrolyte, and the patented structure of the battery pack “Tianzige” frame, DP980 high-strength steel + composite bottom guard, and rapid pressure relief explosion-proof valve are designed to fully ensure battery safety. At the same time, Geely Star Intelligent Computing Center vehicle-cloud integration + BMS battery doctor monitoring and protection can provide online real-time diagnosis, long-term warning, real-time monitoring and other functions of battery fault cloud in the cloud. The Aegis battery safety system truly ensures battery safety at the system level.
“No fire, no explosion” is only the entry standard, and all-round “safety redundancy” is the goal
Whether it’s electrification or intelligence, safety isNew energy vehiclesThe fundamental. In Geely’s view, safety has nothing to do with configuration, let alone price segments, it is the original intention of Geely car manufacturing and the cornerstone of innovation. Without the “1” of safety, there are countless wonderful “0s” behind, and everything can only return to zero. Recently, the Ministry of Industry and Information Technology issued the latest battery safety requirements, upgrading “no fire, no explosion” to a mandatory requirement for the first time, which is called “the strictest battery safety order in history”. For Geely, this is only the entry standard for power battery safety, and Geely’s goal is to pursue all-round “safety redundancy”.
For example, in terms of battery testing, Geely requires batteries to pass 36 safety tests under extreme working conditions in all scenarios, which is 12 more than the new national standard. Among them, 23 test standards exceeded the “new national standard”. In addition, Geely also took the initiative to add 12 test contents such as the bottom ball hit, scratch test, and pedal test of the battery pack.
As early as 2021, Geely joined hands with national authorities to take the lead in formulating the first group standard for bottom protection of new energy vehicles in China. It is worth mentioning that before Geely, basically no car company had done a bottom crash test. Geely is also the first in the industry to do it, 30 kilometers per hour vehicle forward scraping test, 20 kilometers per hour vehicle negative impact is not damaged, solving the most feared electric vehicle is battery damage and safety accidents caused by bottom collisions. The new national standard also upgrades the “bottom collision protection” requirement to a national mandatory standard.
As a major participant in this group standard, during this year’s Shanghai Auto Show, Geely also announced that it will open the battery bottom safety patent set to the whole industry to better protect vehicles, as well as life and property safety in more extreme scenarios. Comprehensively exceeding the national standard is the driving force for Geely’s continuous innovation in safety. As of March, Geely ranked first among Chinese car companies with 1,562 safety patents published by the China Automobile Center.
Brief summary:Thanks to Geely’s strict safety standards, Geely Galaxy Starship 7 EM-i exceeded the indicators of the new national standard in advance, truly achieving safer oil and electricity isolation, stronger battery packaging, and more stable battery cells. It is believed that the success of this test marks a new stage in the safety performance of plug-in hybrid models and sets a technical benchmark for the industry. In the future, whether it can pass the “gasoline and electricity thorn” test may become an important reference for measuring the safety of plug-in hybrid models.
