| 摘要： | The news that Volvo CE is now spending heavily on research and development work into the use of fuel cells for construction machinery applications should surely come as no surprise. The firm has been very vocal about its wish to become carbon neutral in coming years and has some of the strongest stances on sustainability of any of the construction equipment manufacturers. Volvo CE has already introduced all-electric machines to the market and with the promise of more to come, although it was beaten to the block by German company Wacker Neuson, with the latter now offering an extensive array of battery-powered models. However, Volvo CE, as well as a number of other firms offering electric machines, have also agreed that there are distinct limitations with regard to electric equipment featuring battery power. For compact machines used in rental applications, the number of hours clocked/day can be comparatively low, allowing even a fairly modest battery array to be able to provide sufficient power. And with an electric machine, when a unit is standing ready for use it draws no power from the battery, which is very different from a comparable diesel unit with its engine at idle that continues to sip fuel. |
