Electric road sweeper, battery - powered, low threshold of research and development, research and development likely to succeed, but the battery itself functions such as power density is small, the quality of the output power of small, large, bulky, you must charge and long charging time restrictions and limited battery life, and electric current sweeping poor performance, and only suitable for regional use. Far more is to create a bus, because buses small radius, good for charging, space, large carrying capacity, using slower speeds, easier to reduce the lack of impact on the vehicle battery itself.
Hydrogen fuel cell road vehicles using fuel cells, stored on the road of hydrogen or nitrogen compounds of nitrogen, and then a chemical reaction with oxygen in the air to produce electricity and hydrogen fuel cell road almost no emissions of harmful emissions, are less polluting electric sweeper's focus, the ultimate goal. Hydrogen and hydrogen fuel cell power density, fill time is short on storage his charge, sweeping vehicle performance than Pure hydrogen fuel cell electric sweeper much good.
But due to fuel power his high cost of technology, hydrogen permeability of high, store and transfer of hydrogen have greater difficulty, current nitrogen tender battery sweeper still in development stage. American General companies now spend most of their time on nitrogen Jersey material on the battery research and development of clean cars, plans in 2010 to become the world's first manufacturer of the year 1 million. The pre - sided think, 203,012,040 years, sweeping vehicle fuel cells will become the world's Clean Car Market leading products.
In the electric road sweeper is not yet totally full, the, sweeping the hydrogen fuel cell cars will take a long time to the commercialization of cases, people and development of hybrid electric sweeper. Hybrid Electric sweeper operating principle is, in addition to using power - driven auxiliary to the traditional green oil engine, when the battery voltage drop will start the traditional engine to continue running, and in real time to charge the battery, it can solve electric troubles sweep the floor car park charge. Due to retain the traditional combustion engine, hybrid sweeping emission cars still exist, but reduced a lot, so hybrid sweeping the floor of the car should only be a transitional product
Three electric sweeping the car's position in the development process can use a simple word to describe : Pure Electronic sweep the car is one door, hybrid sweeping cars is the transition oxide fuel battery electric road vehicle was the target. Due to differences in views on the issue, dominated by General Motors of the US companies that develop hydrogen fuel powered electric road sweeper is working more directly with the target, you can cross over it, saving less time, so put more power in hydrogen and metal batteries on the road. And to the company as Japanese companies were of the view that the transition to a hydrogen - fuel battery electric road vehicle It's a long time, this time to market, opportunities should not be missed, so they have used more force in development of hybrid road.
