New energy vehicles are in full swing and are experiencing unprecedented rapid development. Nichicon, a global leader in capacitors and aluminum capacitors and film capacitors, is also keeping pace with the development of new energy vehicles, taking the lead and setting the market. At the Shanghai Electronics Show in Munich, which ended recently, Nikko showed products and solutions using its capacitor technology in electric vehicles and energy storage.
According to Mao Jidong, director and deputy general manager of Nikko Electronics Trading (Shanghai) Co., Ltd., Nikko has comprehensive solutions for electric vehicles and new energy vehicles. Its key components are capacitors, vehicle molds, fast charging solutions, wireless charging systems, The V2H system has achieved growth from 8% to 2 digits in the new energy vehicle market.
Aluminum electrolytic capacitors and film capacitors for EV
In order to cope with the high performance of aluminum electrolytic capacitors required in the automotive field, Nichicon has developed a GYA series conductive polymer hybrid aluminum electrolytic capacitor that supports high temperature, long life and high ripple. The GYA series is characterized by the fact that the electrolyte is a mixture of an electrolyte (liquid) and a high molecular polymer (solid), which changes the single form of the conventional electrolyte (single liquid or pure solid). This can achieve good complementarity and get more stable electrical performance. Compared with liquid aluminum electrolytic capacitors, conductive polymer-mixed aluminum electrolytic capacitors have excellent ESR performance in the high-frequency field, and maintain stable ESR performance even with temperature changes. It can achieve a long life of more than 1000 hours at 125 ° C, and can achieve high ripple more than several times in terms of allowing ripple current. Further, since the electrolyte can reach the bottom of the etching hole, it is possible to obtain a capacitance value exceeding several times as compared with the ordinary conductive polymer aluminum solid electrolytic capacitor. By developing an electrolyte that matches the physical properties of Nikko's exclusive conductive polymer and the properties of conductive polymer membranes, it achieves the industry's highest level of 4,000 hours of assurance and high reliability at 125 °C.
GYA series
With the high vibration resistance requirements of various control units of the automobile, the UXY series lead-type aluminum electrolytic capacitors developed by Nichicon have six grooves in the design to provide anti-vibration. The former capacitor is a cylinder. When the vibration occurs, the middle lead may break. The grooved design can fix the electrode and electrolyte and fix it from the acceleration of 19G vibration to 40G vibration acceleration. It can support high temperatures up to 135 degrees and has the highest level of vibration resistance in the industry, making it ideal for use in vibration environments required in the automotive market.
UXY series
In addition, compared to conventional capacitors, Nichicon's EV/HV/PHV film capacitors have the absolute advantage of long life, almost the same life as the car, and can reach 10 years in harsh high temperature environments. At the same time, miniaturization, weight reduction, and shape customization of the product can be achieved by thinning the film and optimizing the structural design. The so-called shape customization can be achieved because the film capacitors are composed of a small number of small parts, which can be arbitrarily combined to form a customized shape according to the capacity of the customer's car or the size of the engine. In addition, the number of terminals can also be customized.
Film capacitor
Car fast charging pile
The rapid development of electric vehicles has driven the wider application of Nikko capacitor products. Using its technological advantages in capacitors, Nikko has developed a fast charging pile device for EV/PHV that is available in four sizes of 10kW, 25kW, 35kW and 50kW. The advantages of these fast charging piles are small size, low cost and high reliability.
In addition, Nikko has signed an EV automotive wireless charging license agreement with Qualcomm, which will incorporate Qualcomm Halo WEVC technology into its products to support PHEV and EV manufacturers in commercializing WEVC systems.
Portable external charger Power Mover
Power Mover, a portable external charger that was launched in September 2017, is a haulable luggage type with a weight of 30kg and an output of 4.5kw. It can be conveniently placed in electric vehicles (EV) and plug-in hybrids. The trunk of the power car (PHV) and fuel cell vehicle (FCV) is used when needed.
The energy stored in the EV/FCV/PHV can be used as a large-capacity battery. When a disaster strikes or a regional power outage, it can easily take power from the EV/PHV/FCV and then convert it into AC to supply power for the refuge, ambulance, and fire engine. To ensure safe use of electricity in an emergency. Family trips can also carry Power Mover to meet the needs of small appliances such as electronic grills.
Three-in-one hybrid power storage system
Nikko's first "three-in-one hybrid power storage system" is a new concept environmental protection system that connects solar cells and batteries and large-capacity batteries for electric vehicles (EV). It uses solar cells to generate electricity. Household electricity and electricity storage can also drive electric vehicles. This ecosystem shows people the new form of the future household electricity system, that is, humans can make full use of the solar power given by nature to complete the power supply for homes and cars, so that people can enjoy a colorful and environmentally friendly life.
The "three-in-one hybrid power storage system" consists of three parts: a household power storage system, a three-in-one power conditioner, and a V2H (Vehicle to Home) system. The household power storage system uses the capacitive components in the device to store electrical energy and achieve charging and discharging by means of a lithium ion battery. In addition to meeting household electricity, the system can also be used as an emergency power supply system. The core technology of the V2H system is based on Nikko's capacitive technology, which can be used to charge electric vehicles. The general practice is to charge the car through the V2H system when the electricity cost is low, and use the electric energy stored in the car to supply power to the home during the high price of electricity or during the power outage, so as to avoid energy peaks and save energy. the goal of. The three-in-one power conditioner is the core and central control of the entire "three-in-one hybrid power storage system". Its function is to store electrical energy into the battery unit of the household power storage system through power conversion when the solar panel absorbs solar energy. For home use (such as lighting, air conditioning, TV, computers, etc.), you can also charge your car through V2H. In addition, when the household power storage is left, the three-in-one power conditioner can also return or sell the power in the household power storage system to the power company. At the same time, it is also possible to convert the electric energy on the electric vehicle into household power supply during the power outage of the home, for example, using the electric power in the car to provide electric energy for the home lighting, air conditioning, television, and the like. The third function of the three-in-one power conditioner is to enable power transfer between the home battery and the EV battery (ELEMOVE). When the EV is absent, the power of the solar cell can be stored in the battery, and the EV is charged from the battery when the EV returns, thereby achieving carbon-free travel. In the case of a power outage, backup power can be obtained from both the battery and the large capacity battery of the EV.
The "three-in-one hybrid power storage system" can fully utilize solar power to meet the electricity demand of households and automobiles, and achieve the ultimate self-sufficiency of household power. At the same time, the advent of the system will also contribute to the full popularization of EV. effect.
