Electric Vehicle of Fuel-Cell System

Recent years have become crucial in the development and implementation of electric vehicles without hybrid plants and any use of internal combustion engines. Leaders in the development of electric vehicle technology are currently the companies Tesla and Toyota, which, however, offer two different approaches to the power technology of the electric motor.

Toyota offers the FuelCell system – a technology for fuel cells that generate electricity and supply an electric motor. The fuel for the elements is hydrogen, and the product of processing is ordinary water. Tesla continues to follow the path of improving lithium-ion batteries.

The problems and disadvantages of both technologies are well known. For Tesla, this is a limited battery capacity, for Toyota – the complexity of logistics storage and refueling with hydrogen. Both companies successfully overcome difficulties, however, in the long term of wide use of environmentally friendly electromobiles Toyota technology seems to many more promising. First and foremost, from a marketing point of view, since most car owners are still accustomed that it is necessary to pour at least some fuel into the car so that it moves from the place, and not just plug it into the outlet.

Despite the fact that the owner of the company Tesla Ilon Mask as early as the spring of 2016 called the technology of fuel hydrogen elements “unpromising”, Toyota demonstrates the results of its development of fuel cells already in the production cars. After the release of the hydrogen passenger car Mirai, the Japanese company is completing the development of a fuel cell vehicle. And on machines with a greater mass efficiency of electric motors becomes much more obvious.

In the video published by the company, there are comparative tests of trucks with a traditional diesel engine and electric traction. Despite the same load of 16 tons, approximately the same rated engine power in 700 hp. and a torque of about 1800Nm for both engines, the tractor on electric traction accelerates more than twice as fast as its diesel counterpart. This is because the torque from the motors is transmitted directly and continuously to the wheels, while the internal combustion engine works in conjunction with the transmission and provides much less efficiency.

With certainty, it can be said that, whatever the future dominant technology of electric cars power supply, undoubtedly, soon internal combustion engines will finally go to the past.
