بررسی بهترین خودروهای برقی و معرفی 20 خودروی برقی برتر از نگاه برنامه تخته گاز (Top Gear)
در این مقاله به بررسی مشخصات فنی ارزان ترین خودروهای برقی روز دنیا اعم از ظرفیت باتری، توان و گشتاور بیشینه، شتاب و سرعت نهایی، تعداد سرنشین، کارایی و مصرف و قیمت می‌پردازیم.
وسایل نقلیه الکتریکی نه تنها به عنوان جایگزینی مستقیم برای خودروها در حال تکامل شناخته می‌شوند، بلکه بسیاری از خودروسازان تلاش می‌کنند ما را تشویق کنند تا نحوه رفت و آمد خود را دوباره ارزیابی کنیم. حمل و نقل شهری بخش مهمی از این امر است، بنابراین ما نگاهی انداخته‌ایم به اینکه چه خودروهای برقی دو و چهار نفره در دسترس هستند و چه چیزی در راه است.

MR76 77GHz MMW White Paper
Abstract: MR76 is a compact 77GHz front anti-collision radar developed by Hunan Nanoradar Science and Technology Co., Ltd. It can accurately remind drivers of obstacles in front of commercial vehicles by transmitting two-beam fan-shaped microwaves to the front, detecting the reflection of microwaves, judging whether there are obstacles in front, and feedback the relative distance between obstacles and radar.This product adopts double beam design, DBF digital beam synthesis, virtual synthetic aperture, short/long distance dual-mode detection and many other advanced technologies to realize 0.2~170m measurement distance, small size, high sensitivity, stable performance, light weight and easy integration. MR76 performance has been recognized by many partners. The products are applied to the Mid-long distance anti-collison for passenger car, commercial vehicle, special vehicle ,etc.
Radar features:
*Work in 77GHz-ISM-Band for the detection of moving objects
*Compact size (140x70x35mm)
*Accurately measure the direction, range, velocity and angle of moving targets
*Protection class IP67
*Hige detection rate
