Among the electronic components of traditional automobiles, the power system requires the most PCB, with a share of 32%, mainly including engine control units, starters, generators, transmission control devices, fuel injection, power steering systems, etc.; body electronic systems 25%, Mainly include automotive lighting, HVAC, power doors and seats, TPMS, etc.; safety control systems, accounting for about 22%, mainly include ADAS, ABS, airbags, etc.; others also include display, entertainment and other in-vehicle electronic systems.
Compared with traditional cars, new energy vehicles have a significant increase in demand for PCBs due to their unique power system.
New energy vehicles are mainly divided into pure electric vehicles and hybrid electric vehicles. The power system of pure electric vehicles is only composed of electric motors and power batteries, and the drive system is simple. Hybrid vehicles include both an engine and an electric motor. They are mainly driven by a fuel engine during normal driving and are driven by an electric motor when the power is sufficient. The power system of a pure electric vehicle adopts electric drive, which will completely replace the drive system of the traditional car, and therefore generate PCB replacement increments. This part of the replacement increment mainly comes from the electronic control system (MCU, VCU, BMS). For hybrid vehicles, while retaining the drive system of traditional vehicles, a new set of electric drive systems are introduced, which will also generate an increase in the superimposition of automotive PCBs. To
To
It can be seen that the increase in automotive PCB value brought by new energy vehicles includes two parts, namely, the superimposed increase brought by hybrid electric vehicles and the replacement increase brought by pure electric vehicles.
To
As far as the value of automotive electronics is concerned, the superposition increment produced by hybrid electric vehicles is basically the same as the replacement increment produced by pure electric vehicles. In the calculation of the increment of the automobile plate, the distinction between hybrid vehicles and pure electric vehicles is no longer required. To
To
Whether it is hybrid or pure electric, the specific sources of PCB increment are mainly three power control systems (BMS, VCU and MCU):
VCU: It is composed of control circuit and algorithm software. It is the control center of the power system. Its function is to monitor the state of the vehicle and implement the power control decision of the whole vehicle. The control circuit in the VCU needs to use a PCB, and the amount is about 0.03 square meters. To
To
MCU: Composed of control circuit and algorithm software, it is an important unit of the new energy vehicle electronic control system. Its function is to control the operation of the motor according to the decision instructions issued by the VCU, so that it can output the required AC power according to the instructions of the VCU. The PCB consumption of the control circuit in the MCU is about 0.15 square meters. To
To
BMS: The BMS is the core component of the battery cell. Through the collection and calculation of parameters such as voltage, current, temperature, and SOC, it controls the charging and discharging process of the battery to realize the protection and comprehensive management of the battery. The BMS hardware consists of a master control (BCU) and a slave control (BMU). The slave control is installed inside the module to detect cell voltage, current and balance control; the position of the main board is more flexible, and it is used for relay control and state-of-charge value. (SOC) estimation and electrical damage protection, etc.
To
BMS generally uses multi-layer boards with better stability, and the value of a single unit is higher than other circuit boards. The function is to monitor the voltage, current and other indicators of the single battery to achieve balanced control to prevent overvoltage and overcurrent from damaging the battery life and performance. Due to the complex structure of the BMS, a large number of PCBs are required. The main control circuit consumption is about 0.24 square meters, and the single management unit is 2-3 square meters.
To
Because different control units have different process requirements for PCB boards, the prices of products are also quite different. For example, the unit price of the main control circuit board of the BMS unit can be as high as 20,000 yuan/square meter, and the price of the slave control board is 1500-2000 yuan/square meter. In comparison, the PCB used by VCU and MCU is a common board, the added value is not high, and the price is 1,000 yuan/square meter. At the same time, the number of individual management units of various BMSs is also different, resulting in differences in the PCB consumption of different models, which is about 3-5 square meters on average, and the PCB consumption of the whole vehicle is between 5-8 square meters, and the value is about 2000 yuan. , Much higher than traditional high-end cars.

In recent years, the global new energy passenger vehicle market has developed rapidly. According to statistics, the global sales of new energy passenger vehicles in 2013 was only 147,000. From 2014 to 2016, the global sales of new energy passenger vehicles were 350,000, 550,000, and 770,000, respectively, with a compound annual growth rate of 48.3%.
To
As the world’s largest new energy vehicle market, China’s market scale is expanding faster than the global average. From 2015 to 2016, domestic new energy vehicles produced 379,000 and 517,000 vehicles, respectively, taking into account policy objectives, the impact of the point system, and the According to factors such as corporate sales planning, it is conservatively estimated that the domestic production of new energy vehicles from 2017 to 2020 will be 700,000, 1 million, 1.2 million, and 1.5 million, respectively, and the corresponding market penetration rate will gradually increase to about 5%.
To
Based on this calculation, by 2020, new energy vehicles will bring a market increase of at least 3 billion yuan to the domestic automotive sheet market. According to the statistics of the Global Energy Agency (IEA), the total global sales of new energy vehicles will reach 6 million by 2020. It is estimated that new energy vehicles will bring nearly 12 billion market increments to the global automotive sheet market.

Basic knowledge of FPC circuit boardWith the continuous increase in the yield ratio of flexible PCBs and the application and promotion of rigid-flex PCBs, it is now more common to add soft, rigid or rigid-flex when talking about PCBs, and say that it is a few-layer FPC. Generally, an FPC made of a soft insulating substrate is called a soft FPC or a flexible FPC, and a rigid-flex composite PCB is called a rigid-flex PCB. It meets the needs of today's electronic products for high density, high reliability, small scale, and lightweight progress. It also satisfies the strict economic requirements and the needs of market and technology competition. - Fpc flexible circuit board test method and standard 03-08
