Electric car car charger products and solutions

As a capacitor manufacturer specializing in Nikicom, automotive electronics, especially electric vehicles, is one of the most strategic markets for its company in recent years. It is also the company's early deployment and acquisition in the consumer environment of the consumer electronics market. A fast-growing market. As the use of electric vehicles continues to increase, Nichicon continues to introduce a variety of new products and technology solutions, hoping to continue to maintain the technological advantages of the electric vehicle market. Recently, Nikko introduced his products and solutions for the electric vehicle market in 2017 in Beijing.

In addition to the development of the in-vehicle charger for the first mass-produced electric vehicle (EV), the company has promoted environmental related businesses such as electric vehicle (EV) related services such as V2H systems and household and public industrial power storage systems. Nikko officially entered the field of new energy vehicles. The Chinese market is the fastest growing market for electric vehicles, and naturally it has become the focus of Nikko's automotive electronics business. Compared to the traditional industrial power and white goods market, Nikko has grown very fast in the Chinese market in recent years. According to Yamamoto Jun, head of business strategy division of Capacitor Division of Jikang Co., Ltd., China’s sales of electric vehicles exceeded that of the United States in 2016. For Nikko, sales of automotive-related products in the past two or three years have nearly five Times, of course, this part includes the electronic control and electric drive of fuel vehicles. Nikko believes that the development of new energy vehicles in China will flourish with national policies in the future.

At present, Nichicon's solutions for electric vehicles are mainly divided into several major areas, such as automotive molds such as OBC, aluminum electrolytic capacitors and film capacitors. Fast charging solutions include fast charging piles and related capacitor products, and public/industrial power storage systems. , household electricity storage system. According to Mao Jidong, director and deputy general manager of Nikko Shanghai Co., Ltd., this means that for the fast-growing EV market, Nikko offers a wide range of products from key component capacitors to functional molds, from V2H systems supporting public facilities to fast charging piles. s solution.

In terms of key components, Nichicon can provide capacitors and integrated circuit products, which are widely used in automotive transmission systems, chassis and safety device solutions, interior jewelry solutions and external jewelry solutions. In terms of capacitors, the focus is on aluminum electrolytic capacitors for OBC, aluminum electrolytic capacitors for electrical installations, and film capacitors for inverters. Integrated circuits and PTC products are used in EV charger integrated DCDC converters and PTC positive temperature coefficient thermistors. . According to Mao Jidong, Nichicon's automotive electronics products are characterized by high reliability and high temperature characteristics, while also providing a lighter weight product and better seismic performance, thus making the reliability of the entire system more prominent. .

For car companies, the most fundamental is the competitive advantage of Nichicon's products compared to competitors. When it comes to this, Mao Jidong is like a few treasures. Nikko has the development and production of materials and finished products in film capacitors and aluminum electrolytic capacitors. From the processing of components to the completion of all products, the entire process of capacitor production is truly autonomous. The advantage of this is that Nichicon can meet the actual needs of customer development, and fully customized design with reference to the corresponding requirements. For example, by working with research institutes to develop the thinnest PP film, the weight and volume of the entire capacitor can be reduced. Compared with competitor bicycles, the weight of the product can be reduced by 30 kg, thereby reducing the weight of the whole vehicle. For example, when developing a specific mold, you can use the best simulation technology to save customers' mold costs and reduce system development costs. In addition, Nichicon's BCP global production mechanism ensures that Nichicon's products are produced on a production line certified by the car manufacturer, and customers can choose with confidence.

Electric vehicles are booming, and the design of electric vehicles is constantly improving. Compared with the parts of traditional automobiles, electric vehicles have more electronic equipment, and electric power instead of fuel becomes the source of power drive. This is the part of the entire electronic power system. Raise the most demanding challenges.

Aluminum electrolytic capacitors are the traditional advantages of Nikko, and they are also widely used in electric vehicles. Especially in complex circuit design, Nijikang has been working hard to develop more compact and larger. Capacitors of capacity have achieved good results in the cathode material of aluminum electrolytic capacitors. The special Nichicon launches the new GYA series of conductive polymer hybrid aluminum electrolytic capacitors, which combines the advantages of Nikko's previous series of products as a true cathode, while adding conductive polymer and electrolyte to improve The "GYA" series conductive polymer mixed aluminum electrolytic capacitor not only has the film repair function of the aluminum electrolytic capacitor, but also has the ESR characteristics and high heat resistance of the conductive polymer solid electrolytic capacitor. Compared with non-solid aluminum electrolytic capacitors, the "GYA" series achieves a long life of 125 degrees and 1000 hours or more, and allows a ripple current of 4 times or more. On the other hand, compared with the conductive polymer aluminum solid electrolytic capacitor, the leakage is reduced to about 1/5, contributing to the power saving of the unit. Further, since the electrolyte penetrates into the depth of the etching pit of the electrode foil, it is possible to obtain about four times the capacitance occurrence rate as compared with the conventional conductive polymer aluminum solid electrolytic capacitor. By developing an electrolyte solution that matches the physical properties of Nijko's own conductive polymer and the physical properties of the conductive polymer film, the industry's highest level of 4000 hours at 125 °C is guaranteed.

Compared with aluminum electrolytic capacitors, film capacitors have the advantage of absorbing noise and filtering ripple in a high-frequency environment, and the current resistance is only a little worse. From the temperature characteristics, the film capacitor is not as large as the aluminum electrolytic capacitor with a 50% attenuation with temperature change, and the stability is good and the life is longer. Generally, the mission life of aluminum electrolytic capacitors is several thousand to tens of thousands of hours, while film capacitors generally have a service life of more than ten years, enabling maintenance-free operation. For the automotive industry, the problem of service life is very critical. Mao Jidong emphasized that “maintenance-free can maximize the interests of the owners, because after they invest money, in a certain return period, each maintenance requires a cost, maintenance-free Will help the owner save costs as much as possible." The interior environment of the car is relatively harsh. In order to ensure that the film capacitor product is not easily burned out and cause a fire, Mao Jidong said, "Our film capacitors are self-healing, and the fuses on the film can be seen, and there is no connection. Together, there is a gap, because the film capacitor will be short-circuited when it is subjected to the impact of external current. The short circuit will break the film. This part will cause the material to melt when the temperature rises. After the fuse is blown, the two sides are connected together. The area is removed, and it becomes a broken product, so the product is very malleable after self-healing."
