New automotive electrical method, there are two embodiments, a 42V one voltage scheme with the entire car, a different is a 14V/42V double voltage obd コネクタ販売 scheme. Automotive parts manufacturing industry from the former will possess a important impact about the latter much less effect, gentle changeover. Hence, the automotive market tend dual voltage plan.
As earlier because the nineteen nineties, Germany has setup a Car or truck Power Forum (Forumbordnrtz) members to participate in the organizations Volkswagen, Audi, BMW, Opel and Porsche, the company is primarily engaged inside the 42V energy supply specification standardization research, proposed 14V/42V twin voltage power provide process specification 自動車診断機 draft. On top of that, Ford and MIT also initiated the company in the MIT / Industry Alliance users involve Common Motors, Daimler? Mercedes-Benz, BMW, Renault, Volvo, Siemens, Bosch, Motorola, Delphi and also other well-known auto dealer, parts and electronic telecommunications supplier. The company study 14V/42V dual voltage power provide units for automotive electrical and electronic equipment and procedures. To promote the development of this perform, the American Culture of Automotive Engineers (SAE) has also setup a particular dual / higher voltage car digital devices Committee. From the look at in the breadth of participation in this plan examine, this new composition of your electrical process is identified from the intercontinental automotive sector.
14V/42V twin voltage system: automotive X431 Diagun electrical and digital control devices based on the energy usage measurement is split into two groups, small and medium-sized energy like a group making use of 42V voltage provide, energy supply, higher power 14V voltage electrical installations, these means the average power in the array of 400-1000W, respectively, the peak energy is often up to 500-5000W. Improve the voltage value, can cut down the amount of the electrical machine by itself, good quality and loss, is also conducive for the miniaturization from the system control, and strengthen the amount of integration. Such as catalytic converters heater, windshield heater, cooling supporter, electrical, suspension, solenoid valve driven appliances. Regular electrical and electrical installations (including lights, signal, instrument panel, Electric Windows, Central lock control program, engine electronic gas injection products, ignition handle equipment, etc.) will not be power, 14V power supply is GM tech 2 favorable. The brand new power supply system has complete compatibility with regular energy supply method, which can be a simple feature with the system.
14V/42V double voltage conversion course of action is as follows: Air conditioner motor output 42V of high voltage, with a DC / DC converter (DC-DC converter), from 4 2V converted to 14V. Within this method, DC / DC converter energy supply technique is separated ecu チューニング into two diverse voltage stages of the energy supply program, the buck outside, nevertheless in the power distribution on the entire electrical technique control play an important function.
