Dismantle a 100000 yuan BYD "Yuan". Come and see what components are in it.

Is everyone right about mobile phones 、 The dismantling of small consumer electronics such as computers has become routine ？

This time, a securities firm made a big move , He broke down a BYD with a market value of 100000 yuan “ element ”, I also wrote a detailed disassembly report , Swipe the screen of securities companies 、 Automobile and other industries , Netizens also shouted “ hardcore ”.

Haitong International 《 BYD “ element ” Detailed disassembly 》 What are the highlights .

According to the report , This is Haitong metal  +  Car team  "  Haitong automobile laboratory  "  The first time in the disassembly series , For BYD  "  element  ". To dismantle the car ,16 Team members spent 3 months , The parts of the report are all original by field shooting , The team said , I hope to show the details of auto parts with first-hand data .

Haitong International said in the Research Report , The demolished vehicle is 2018 BYD dollars EV360, Manufactured by BYD Automobile Industry Co., Ltd , The manufacturing date is 2018 year 9 month . The model is Zhilian cool white , The maximum permissible total mass is 1870kg. Originally purchased to meet daily commuting needs , mileage 7.38 Thousands of kilometers .

The research report will BYD yuan EV360  Detailed description , Introduced the model 、E platform 230（ System ）、 Historical sales 、 Vehicle evaluation 、 Energy consumption 、 Maintenance 、 Purchase cost, etc .

In terms of car Profile , It includes the model introduction 、E platform 230（ System ）、 Historical sales 、 Vehicle evaluation 、 Energy consumption 、 Maintenance 、 Purchase cost and many other contents .

The disassembly content includes not only structural parts 、 Chassis structure 、 The seat 、 Lamps and lanterns 、 Wire harness 、 The steering wheel +EPS Assembly and other components or parts , There is even sound insulation 、 Main carpet of the whole vehicle 、 Multimedia system 、 Instrument cluster 、 Air conditioning control panel 、 Thermal management system 、 Battery system 、 Electric drive system 、 Tires and so on .

The core chip of the combined instrument controller includes NXP CPU、ISSI SDRAM、MIXC NOR FLASH etc. .

The heat management system adopts the traditional air conditioning refrigeration +PTC Heating mode , Thermal management system includes air conditioning and refrigeration system 、PTC Heating system 、 Coolant / Refrigerant pipeline and control panel .

element EV The battery adopts independent green plant tray , Installed under the chassis , The battery adopts ternary lithium electron , Capacity of 43.2kWh, The energy density of the battery pack is 127Wh/kg, All made by BYD .

Battery pack BMS Using distributed architecture , Including a Freescale central controller （CECU, Outside the battery pack ） And three local controllers （LECU, In the battery pack ）.

Almost every disassembled component is described in pictures and words . The description includes the dimensions of each component 、 weight 、 working principle 、 Dealer quote , Even information about the manufacturer .

It is reported that , Specific data are mainly from Haitong International's own industry research , And the maintenance manual of BYD cars mentioned above , BYD Weibo , And data released by some industry organizations .

Haitong international dismantling electric vehicles is not the first case

Disassembly can better understand the whole automotive products and related industrial chains

It is worth mentioning that , The research method of disassembling electric vehicles is not original by Haitong International , Some foreign research teams have begun to conduct in-depth research by disassembling cars as early as a few years ago , For example, UBS automotive research team 2017 The bolt electric car of Chevrolet was disassembled in ,2018 Disassembled Tesla's Model 3,2021 In, the public was dismantled MEB Built on the exclusive platform of pure electricity ID 3 Electric cars .

Besides ,EDN Electronic technology design has also reported on Toyota 、 American kellesler reverse research BYD Tang .

Regarding this , Yaoshuqiao, an analyst at Haitong international automotive, also said ：“ This practice is relatively rare in China , But from a global perspective , Disassembling cars is not our first research method , So-called ‘ It's on paper ’, Through disassembly, we can have a deeper understanding of the whole automotive products and related industrial chains .”

The following is the detailed disassembly report released by the official wechat of Haitong international research department ：
