Battery-powered vehicles

The importance of lowering automobile emissions has already resulted in changes in car manufacturing. Electric cars, which were popular 100 years ago but fell by the wayside because they could not keep up with gasoline-powered cars, are making a comeback. Although battery-powered vehicles are useful for short, slow trips aroimd a crowded campus, for instance, they continue to be plagued by limited speeds and durations. Automobile manufacturers have alleviated these problems by com-... 

This is not only due to the higher efficiency of battery powered vehicles, but also to the lower efficiency of the overall process necessaiy to assure hydrogen feeding to fuel cells, i.e., production of electricity stalling from the primary resource plus hydrogen production by electrolysis (13% from nuclear and 5% from photovoltaic, to be compared with values corresponding to electricity production...

Early in the twentieth century, cars powered by storage batteries were quite common. About 35% of all cars registered at that time in the United States were battery powered. They were more convenient than vehicles with ICEs that had to be cranked to start the engine. The situation took a turn when an electric starter was patented in 1912 and was then widely introduced. This meant the practically complete displacement of electric cars by today s traditional ICE vehicles. Today, battery-powered vehicles are used only for transport within production plants and for certain home deliveries, such as milk products and mail. 

Battery-powered vehicles are promoted by many countries, including the United States, China and European coimtries, as a means to foster energy independence and, potentially, reduce the greenhouse gas (GHG) emissions stemming from the transportation sector. 

The possible advent of large-scale growth in battery-powered vehicle deployment provides a unique opportunity to delve into the battery supply chain and examine it for any environmental issues or other roadblocks pertaining to material scarcity that may arise as barriers. One key concern is that batteries incorporate materials whose production may incur adverse environmental impacts and consume large amoimts of energy. Additionally, if demand for these materials (especially lithium or cobalt) for batteries outpaces supply, scarcity may become an issue and impact the price and feasibility of large-scale adoption of battery-powered vehicles. 

It is important to note that the vehicle power train for the fuel cell powered system is similar to that of battery powered vehicles. The power conditioning system requirements for vehicles include low EML, high efficiency, low cost, and suitable for intermittent use over a 10 to 15 year lifetime.

Economic viability for battery-powered vehicles today is far from realization. Economy can only be reached if electric vehicles, including all their parts and components, are produced in magnitude series. The step to magnitude series is only...

While there remains some interest in alkaline fuel cells (AFCs) for commercial applications, notably by Zetek as a range extender for battery-powered vehicles, this is at a low level compared with that for PEMFC systems. Modified anode and cathode catalysts have now been developed that supersede the high concentrations of Pt and Pt/Au used in the space Orbiter vehicle. However, there is no consensus on whether precious or base metals are the preferred system. The choice depends on the balance between the required performance and acceptable cost. With increasing interest in the use of hydrogen for fuel cell powered vehicles, interest in the AFC system may increase. On the other hand, it is reported that the new fuel cells for the space shuttle Orbitor vehicles will be PEMFC in preference to the established AFC [12].

Despite the type of fuel or power used on lift trucks, safety precautions must be in place. Each source of power has both positive and negative points. Battery-powered vehicles do not produce carbon monoxide but can expose employees to sulfuric acid, the danger of explosion, electricity from chargers, and back injuries from pulling or pushing batteries into place.
