December 28, the first domestic PHEV open crash test gives the answer.
The video from the scene of the reporter can be seen, the new red flag H7 PHEV and Jiefang JH6 heavy truck collision, the crash test results of both cars have performed very well, especially the new red flag PHEV. National Car Testing Center real car The test results released by the collision cell showed that the new Hongqi PHEV fulfilled the requirements in terms of body structure, restraint system and electrical safety after the test. All the vehicles and the occupants of the vehicle were protected in all aspects and the accident was minimized Security risks show a state of trust near full marks in the case of dummies damage.
National car test center real car collision room director Zhang Xianglei released test results
It is understood that in this experiment, the new Hongqi H7 PHEV Jiefang JH6 with a relative speed of 50.4km / h, 100% overlapping rate of collisions in the new Hongqi H7 PHEV placed four dummy, of which the front row of two male leave People, the back of a male dummy and a female dummy. National car test center real car collision room director Zhang Xianglei introduction, the reason is different from the previous test, mainly to consider the red flag locked official car demand, better The test vehicle safety.
In the crash test, the door was not opened and all the doors could be easily opened after the test.After the crash test, the new Hongqi PHEV crew cabin maintained a good integrity with a maximum intrusion amount of 12mm on the A-pillar and a maximum intrusion of 7mm on the instrument panel, 18mm, steering column no backward displacement, crew living space can be guaranteed; no leakage of the fuel system, the engine compartment without fire risk, to avoid a fire after the accident.Constraint system, the new red flag PHEV all seat system did not appear Failure, there is no twist, flip, slippage and other anomalies; front seat belt preload in the 28ms, all seat belts have not failed, and the dummy can be effectively fixed in the seat; airbag deployment time is normal, after the collision 23ms explosion, the dummies contact the airbag, the airbag just fully inflated, unfolds a reasonable shape, dummy head contact with the airbag center.Zhang Xianglei said the new red flag PHEV restraint system is good to play a role in the protection of the occupants of the vehicle after the accident , And the rear dummy did not collide with the front seats after the accident, avoiding the secondary injury to the rear passengers after the collision.
The safety of the battery system is the focus of the collision test.However, due to the existence of the power battery, the PHEV significantly increases the weight of the vehicle and the total kinetic energy of the collision and tests the electric safety of the new energy car very seriously, especially the PHEV Vehicle models of power batteries and high-voltage lines in the collision will be a severe test.If not been effectively optimized design, the vehicle after the collision there is leakage, fire or even explosion risk.In addition, such as the battery structure is severely damaged, the electrolyte Will leak to the car, causing serious pollution of the surrounding environment.
The crash test, the new red flag PHEV electrical safety performance is also very satisfactory anti-shock protection, insulation resistance, high voltage bus positive and the insulation resistance between the platform is 1543Ω / V, high voltage bus negative and power platform Insulation resistance between the 1571Ω / V, are greater than 100Ω / V. Physical protection, the vehicle has IPXXB level of protection, high-voltage components between the shell and the platform resistance is 0.001Ω, lower than the relevant standard 0.1Ω. After the test, there was no leakage of electrolyte in the battery pack. After the test, REESS remained in position and did not enter the passenger compartment. No fire or explosion occurred. The popular point was that the collision results of the new Hongxiang PHEV fully met the requirements of relevant standards, The majority of the index was significantly higher than the standard required level, the above-mentioned concerns on the safety of PHEV did not happen.Li Hongjian, vice president of FAW R & D headquarters said that next year C-NCAP will be included in the test of new energy vehicles, the Red Flag is confident in the relevant Crash test achieved better results, and according to the plan, Hongqi will release a number of safety technology achievements next year.
The first PHEV open crash test, the new Hongqi H7 did not choose the traditional barrier as a collision object, but with a higher quality JH6 Jiefang heavy truck, test more difficult to increase, but also test the safety performance of JH6 liberation. , Cars and heavy truck collision, the most worried about is the car into the bottom of the truck, the test, Jiefang JH6 in the front-end strength and front-end protection to meet the test requirements, the new Hongqi H7 PHEV did not drill into, and no cab Deformation, bearing structure is not invalid.
