Automotive wiring harness

Car value, create new value for ascension bold challenge to use group comprehensive strength, self-developed products ~ CASE specifications

In project development system

CAS - EV development promote department (hereinafter referred to as the "CAS - EV") dealing with the CASE of business's basic attitude is: in the "car" into "environmental energy enterprise" and "cause" of information communication, creating can realize auto, energy and communications social infrastructure in the field of the new products and new technology.Sumitomo electric group is committed to through the "electric and energy field" and "Internet and information communication" these two strengths to expand business.In particular, is based on auto harness the core business, to create "the future of automotive wiring harness" related products.At this time is the key to the project system.Although CAS - EV within multiple positions, but from the system, not more than the lower relationship between jobs in CASE business.First of all, the by infrastructure related upstream team set out to explore, and then in the architecture, "Autonomous (Autonomous)", "Electric (Electric)", "Connected" and MaaS * CASE to carry on the practice, in the field of establishing specific projects and development.Now push the main projects include "high-speed communication" and "vehicle structure", "battery", "architecture" and "infrastructure", etc.The following will introduce since the birth of the findings of the project and product development.

* MaaS (travel as a Service) is the abbreviation of "Mobility as a Service".Will past and transportation services, automatic driving and AI together a variety of technologies such as a new generation of transport services

The high-speed and large capacity of communication necessary to achieve automatic driving

CASE "Connected" by sensors in the vehicle condition and the surrounding roads and other data, summarize and analysis through the network, to achieve "car" of the Internet.If can improve "Connected", to ensure safety, then can realize "Autonomous", which fully automated driving.

CAS - EV to achieve "connected car" autopilot, has been committed to high speed and large capacity of communication research.Around the large current and high speed communication connector, high-speed communication wiring harness the necessary conditions to carry out various validation work, implements the automatic driving "Connected" required for level 3.Level 3 is refers to under certain conditions, by all the driving system for operation, in an emergency situation, carried out by the driver driving state (5) for fully automated driving.Meet at 3 "high-speed communication wire / 100 m Ethernet" supplied to auto makers and encapsulation.In addition, as a vehicle with the outside world, "connected" any move
CAS - EV involved in ibaraki prefecture, the introduction of automatic driving bus route and developing empirical experiments.Coordination with vehicles in the terminal of the sensor and road shop communication control device, in particular the driveway running route bus automatic driving into a target, to carry out the project.In the future, vehicle will also carry the camera and other peripheral detection sensors, high speed communication will further inside the car, one day, will shift from previous electrical communication for optical communication and the light beam.By implementing high-speed and large capacity of communication, the CAS - EV is committed to build the car inside "car" of the Internet.

From the infrastructure to implement electric batteries and motor

CASE one of the themes of "Electric (Electric)" is the strengths of sumitomo Electric group, CAS - EV is working to develop all kinds of Electric parts.You first need to meet with large current of battery.Will be about 400 v high voltage control ECU (electronic control unit), the measurement sensors, connecting wiring harness, etc and battery together, and then realize the lightweight, durable sex, the electric car safety and economy, this is the high voltage battery pack.Its ultimate form is combined with vehicle structure without battery shell.In addition, can connect more complex battery circuit of high voltage junction box is composed of CAS - EV development.

Inverter control power, electric motor, the tire rotation through gear, etc.Has a huge advantage in small, lightweight and cost "E" - the Axle of the drive system will be in harmony for an organic whole.In motor drive efficiency of ascension in the inner line, help to miniaturization of the pressed powder core products, can greatly simplify wiring job collector ring.CAS - EV is developing E - all kinds of Axle parts and machines, including around the frequency converter is used to maintain a constant current, reactor, ensure the line from the influence of noise terminal row, wiring harness and equipment for the sensor module, etc.

In addition, the CAS - EV charging is focusing on development, infrastructure and related electric automobile specialized wiring harness and connectors, including shorten the charging time of large power charging gun and outlet of development, to enhance the efficiency and to households and power system, power supply for the purpose of energy management, battery recycling, etc.And actively promote the development and KuoXiao of electric products.

Battery conductive plate module (BBM)

Electric cars carrying cell is known as cell monomer battery stratification and connected, power required to produce drive."Conductive board module" is used in the monomer battery electrodes and pressure line connection between is indispensable parts, at a high current important parts is also influence the efficiency of the battery charge and discharge.CAS - EV promote the low resistance connection between the electrode and the conductive plate and save space.

In order to ensure the distance, the battery pack is the large capacity, the number of single cells carry also continue to increase, so the zero of the battery pack goods need to be further save space.In order to solve the issue, the CAS - EV adopted "FPC (flexible printed circuit board).Compared with wire, FPC can realize wiring high density and thin, helps to reduce the thickness of the battery pack.

Play a group of comprehensive strength, walking in the frontier

CAS - EV development promote department formally established has been 2 years and a half.So far around departments to move, minister hirai said:

"We are committed to become a development partner to the automotive industry, devotedly to carry out the relevant measures.Carmakers are also concluded that the results gave a high praise to us.But to be honest, we didn't go to the halfway up the hill.From suppliers to partners, work style and consciousness also need to change.I think at the beginning of its establishment and department members are growing, but need to further promote the consciousness and thinking.And remember "from the Angle of view of the car", promoting the work of "car value" concept.As a partner to the automotive industry, in order to obtain the high evaluation, I will continue to work hard.(horizontal well)

In the future, how to accelerate the CAS - EV measures, how to play the high prestige of sumitomo electric group?

"The first subject is the CAS - EV members by accumulating experience, absorb the knowledge and skills, the difference with other company, grow up to high standards of the partner.Seeds and optimizing the use of this company has a variety of business, enhance their strength.CASE's action is not limited to the automobile enterprise headquarters, we should cooperate with other department of fusion, or seek association company's support, I think it is very important.I firmly believe that as long as the play to the comprehensive strength of the sumitomo electric group, will be able to go along with car manufacturers in the era of the CASE, and promote the development of CASE era."(horizontal well)

CASE of appearance of impact in various fields, for the automotive industry bring dramatic change.Cars and society in the new era, in the face of new age topics, sumitomo electric group has courage to challenge, the future will bear rich fruits!
