Mild Hybrid Electric Vehicle (MHEV) – electrical architecture
This paper provides a technical review of position and speed sensorless methods for controlling Brushless Direct Current BLDC motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology. Then, in this paper sensorless advances are reviewed and recent developments in this area are introduced with their inherent advantages and drawbacks, including the analysis of practical implementation issues and applications. For the past two decades several Asian countries such as Japan, which have been under pressure from high energy prices, have implemented variable speed PM motor drives for energy saving applications such as air conditioners and refrigerators [ 1 ]. On the other hand, the U. Therefore recently, the increase in energy prices spurs higher demands of variable speed PM motor drives. Also, recent rapid proliferation of motor drives into the automobile industry, based on hybrid drives, generates a serious demand for high efficient PM motor drives, and this was the beginning of interest in BLDC motors.
In this article tutorial we are going to discuss about the electrical architecture of a mild hybrid electric vehicle MHEV. By electrical architecture also called electrical topology we understand the high level overview of the electrical components and the connections between them. Before going through this article, for a better understanding of hybrid electric vehicles HEVs in general and MHEVs in particular, read the following articles:. The battery needs to supply all the required electrical energy during the engine start, which includes the starter, ignition system, fuel injection system, various electronic control units, safety and comfort electronic devices, lighting, and any other electrical equipment. After the engine has been started and it runs autonomous, the generator needs to supply all the electrical energy to the loads and also charge the 12V battery. Depending on the operating conditions of the vehicle and engine, the amount of electrical current drawn from the battery varies, as described in the table below. The lower the engine temperature, during starting, the higher the friction torque, the higher the current drawn from the battery.

In automobiles , a volt electrical system was an electrical power standard proposed in the late s. It was intended to allow more powerful electrically-driven accessories, and lighter automobile wiring harnesses. Electric motors were proposed to be used for power steering or other systems, providing more compact installations and eliminating the weight of drive belts or large wires for high-current loads. The higher voltage was selected to provide greater power capacity for wiring and devices on one hand, and to stay under the 50 volt limit used as a guideline for electric shock hazard. The European auto manufacturer Daimler-Benz proposed a 42V brand name for the conversion. The SAE discussed an increased automobile standard voltage as early as

Вы не поставили в известность Лиланда Фонтейна. Терпение Стратмора иссякло. Он взорвался: - Сьюзан, выслушай. Я вызвал тебя сюда, потому что мне нужен союзник, а не следователь.
В последние несколько лет наша работа здесь, в агентстве, становилась все более трудной. Мы столкнулись с врагами, которые, как мне казалось, никогда не посмеют бросить нам вызов. Я говорю о наших собственных гражданах. О юристах, фанатичных борцах за гражданские права, о Фонде электронных границ - они все приняли в этом участие, но дело в другом.
