At the National Convention Center , Chang’an released the Shangri La plan , And shouted out to walk with the motherland , Walk with the national automobile industry , Committed to promoting the high-quality development of China’s new energy vehicle industry , The slogan of the .

2021 year , Changan’s new energy brand dark blue was officially born .

One year after its birth ,2022 year 4 month 21 Japan , Changan dark blue ushered in its first activity —— For the first time, the new special platform for pure electric drive EPA1 Platform , And analyzed the first mass production product under the platform ,C385.

Look back , Five years have passed since the release of the Shangri La plan , from 2017 Year to 2022, Sharpen a sword in five years , This time, Changan dark blue didn’t disappoint people , Give us 、 Or to the whole industry , Brought it once “ crit ”.

First say EPA1 platform , It is a special platform for electric drive in the form of multi energy supplement built by Chang’an , It has four high attributes : The electric efficiency driven by the ultimate power system ; Later driven into genes , Give consideration to the high performance of 4WD ; High intelligence based on domain control electronic and electrical architecture ; High security of three-layer protection of core car cloud .

According to Deng Chenghao, general manager of Chang’an new energy , The three major pain points of electric vehicles in the eyes of Chang’an new energy are short endurance 、 The energy supplement is slow and the safety is in doubt , To solve these pain points , Su Zhong, the chief product officer, and the team have determined the cool points of three electric vehicle customers : High efficiency and environmental protection 、 Digital experience 、 Ultimate performance .

In order to achieve these three cool points . In terms of efficiency , For booster and hydrogen fuel cell vehicles , In addition to the power system drive electric efficiency , The R & D team also pays attention to the power generation efficiency index of the power system , This refers to the net electricity output per unit weight of fuel or hydrogen . For example, at present , The electric efficiency of the mainstream industry is about 70%-75%. Chang’an new energy has taken a series of optimization measures , Electrical efficiency can reach 78%, Higher than the best level in the industry .

Besides , Changan dark blue is also from the electric drive system 、 Extended range system and hydrogen fuel system , Put forward a large number of original solutions . For example, a new generation of self-developed high-frequency pulse heating technology , It can realize extreme heating at ultra-low temperature , stay -30℃ In the environment , The heating speed of the battery can reach 4℃/ minute , Low temperature dynamic performance is improved 50% above , Low temperature charging performance is shortened 15% above , It greatly alleviates the experience of electric vehicles in extremely cold weather .

at present , In the technology of super collector drive , The number of patents applied by Changan shenlanlei has reached 163 term .

And in terms of security ,EPA1 The platform is based on 2021 edition C-NCAP Five star safety standard , Adopt five horizontal and nine vertical embracing body , Proportion of high strength steel 45%, And adopt all-round battery safety protection . use 5+1 Information security level privacy protection , involve IT Defense Technology 、 Identity Authentication 、 Channel physical isolation 、 Hardware security module (HSM)、SecOC Secure communications .

In terms of battery safety ,EPA1 The platform launched iBC Digital battery housekeeper . In terms of pre control management , The platform can realize wire connection + Digital process control , vehicle + cloud BMS Double impact monitoring . In digital temperature control management , The platform adopts space class full battery insulation technology 、 Alcohol cooling and efficient heat dissipation 、 Transient pressure relief technology 、 Overpressure seal control 、 Global short circuit prevention technology 、 Directional pressure sensing and temperature exhaust 、 Full time temperature sensing alarm and other technologies .

Besides, the car , Changan dark blue C385 It is divided into pure electricity 、 Three versions of extended range and hydrogen electricity , The hydrogen electric version is the first mass production hydrogen electric vehicle in China .

New car positioning pure electric car running model , The length, width and height are respectively 4820mm、1890mm and 1480mm, The wheelbase is 2900mm, The drag coefficient is 0.23Cd. The whole new car adopts rear wheel actuation , The rear suspension adopts H Arm type multi link independent suspension system . Besides ,C385 It’s also equipped with 19 Inch wheel , The car is equipped with an intelligent steering system 14.6 Inch sunflower screen , Equipped with electric hatchback door .
