A new generation of super collector drive


From the earliest motor 、 Electronic control 、 Fully decentralized layout of high voltage system , To the later electric drive two in one 、 And today's mainstream three in one , The electric drive system of electric vehicle is always pursuing high integration . Integration as much as possible can not only make the core system smaller , Higher volume power density , It can also reduce the failure rate and improve the driving efficiency . Changan Automobile passes through new materials 、 New technology 、 Deep integration of advanced technologies such as artificial intelligence , Create a super set with super efficiency ( No mistake , Superset 、 Integrated pun ) Electric drive system , It represents the development trend of technology integration .

Another black technology released this time —— High frequency pulse heating technology , It is an indispensable link for super collector drive to achieve high efficiency . This technology takes advantage of the inductance and switching characteristics of the electric drive , High frequency pulse current is generated between the driving battery and the electric drive , Self heating is realized through the internal resistance of the battery . Compared with the traditional heating method , Higher heating efficiency 、 Heat more evenly .


According to the official test of Chang'an Automobile , stay -30℃ In the environment ,5 Minutes to warm up 20℃, Quickly improve battery charging and discharging efficiency and charging and discharging performance , Realize ultra-low temperature travel and enjoy driving . Cooperate with waste heat recovery technology , Increase range 40-70KM.


First strategic model C385 Appearance ,2022 Launched in 2013


As “ shangri-la ” The latest achievements of the steady progress of the plan , The first strategic model of Changan Automobile's new special electric platform C385 It also appeared at the science and technology ecological Conference , The new car is a collection of Changan Automobile's many years of manufacturing experience 、 Technology precipitates in one , Realize the multi-dimensional evolution of automobile value .

appearance , changan C385 Adopt the sliding back shape loved by young people today , Integrate a lot of Technology 、 Sports design elements , Cooperate with the hidden door handle with a sense of technology and luxury 、 Panoramic skylight with wide view 、 A penetrating tail lamp with a sharp edge 、 And sharp and decisive side lines , Realize the overall evolution of appearance value .


In terms of technology configuration , changan C385 With the world's first APA7.0 Remote valet parking system .APA7.0 Using super sensing hardware system : Use together 27 A sensor ,5 It is designed to solve the problem of parking lot perception 4D Imaging millimeter wave radar ,12 A new generation of coded ultrasonic radar ,10 A high-performance camera , Single camera pixels up to 800 ten thousand . In the algorithm, deep learning and multi-sensor fusion are used to realize accurate perception ; Accurate positioning is achieved through the fusion of visual semantics and features ; Deal with the complex and changeable parking environment through graph search and optimization algorithm .

Finally, it can be realized under the premise of meeting the relevant national laws and regulations , Unmanned autonomous queue parking function outside the first garage —— Users can get off directly outside the garage , The system queues up independently , Drive the vehicle through the gate 、 Look for parking space independently , Self parking .


Besides , The new generation of super collector drive system mentioned above will also be used for the first time in C385 It carries . At the same time, the new car has also achieved comprehensive evolution in service , Through the luxurious private butler service tailored for users , Open more intelligent for the future 、 More secure 、 More convenient green travel .
