What kind of pure electric vehicle is driven by hub motor?

The range of SIM-LEI can reach 333 kilometers on a single charge.

Professor Shimizu Hiroshi has been studying electric vehicles driven by in-wheel motors for more than 30 years, and has continuously developed 65,438+00. In order to solve the bottleneck problems of poor endurance and high price of electric vehicles, the experts of R&D team focused on reducing the weight of body materials, improving the utilization efficiency of renewable energy, adopting ultra-low rolling resistance tires and boldly using the "fish" streamlined design to minimize the driving resistance coefficient, and finally developed a hub-type electric vehicle that is different from the concept of electric vehicles that have appeared so far.

This wheel-type electric vehicle is 4.7 meters long, 1.6 meters wide, 1.55 meters high, with four people, a total weight of 1650 kg, a single charge of 333 kilometers in JC08 mode, an energy consumption of 77Wh/km and an average speed of 100 km. Very futuristic instrument panel, 19 inch reversing monitor, all buttons are concentrated on the left side of the steering wheel, and lithium battery boxes such as drawers are placed under the car. The hub motor can be designed as four-wheel two-drive, four-wheel four-drive and eight-wheel eight-drive, which is suitable for both new car design and old car reconstruction.

The design of in-wheel motor is also different from the conventional in-wheel motor, which changes the traditional flat drive of electric vehicle and adopts reducer mode and direct drive mode. The motor built in the wheel hub relies on the miniaturization and high efficiency of the motor, which has the advantages of high energy efficiency, expanded utilization space and high control performance. Compared with electric vehicles that use motors instead of engines, the cruising range can be extended by more than 30%.

Professor Shimizu said that the reversing monitor will also have information exchange and entertainment functions in the future. It can be said that the design concept and function of automobile have brought a revolution to today's automobile industry. In order to realize the desire not only to build their own cars, but also to provide cutting-edge technology and information to enterprises and institutions that produce electric vehicles at low prices, the professor established a high-tech company "SIM-DRIVE" with 34 enterprises and institutions in August 2009, and all investment enterprises can enjoy scientific research results according to commercial rules.
