After a century of applications has not yet resolved the dichotomy between energy density and power density. Failed marriages or aggregate them, let alone adapt to suit particular requirements. Opel's engineers admit therefore that the development of technologies for the electric mobility has so far proved very linear program, without which no revolution has been able to accelerate their dissemination.
Emblematic parallelism between the Ampera and Impuls, a prototype electric-based Astra F was originally built in 1992: the first delivers 111 kW, has a 16 kWh battery pack (180 kg) for an energy density of 90 Wh / kg, while the Impuls has 45 kW and uses a 26 kWh battery (325 kg) for a density of 80 Wh / kg.
In developing an electric car was then forced to face a conceptual choice: take advantage of better technology BEV (more autonomy and recharge times content) or rely on the schema FCEVO more effective in ensuring high performance and great flexibility of use? Within the next four years in large series Opel will introduce two "philosophies", starting already from the end of 2011 its program of alternative mobility: the Ampera debut at first, followed in 2013 by an anchor and mysterious electrical utility in 2015 by a powered vehicle by fuel cells.
In each case the manufacturer of lightning is already working to optimize the next-generation technologies, seeking to reduce costs and increase recycling of materials such as spent batteries into the effectiveness of the ideal operating range. These projects are coordinated in the development center near Frankfurt, where there are one of the four amps produced so far, the Meriva and Hydrogen MeRegio 4.
The actual value of the technical and technological Ampera Mature analyzing the numbers for the daily movements of German motorists as they traveled to a greater extent (80%) about 60 miles every day. This detection range of a few places when evaluating the behavior of other European drivers.
The German sedan offers 40 to 80 km of autonomy in electric mode, rising to 500 in combined mode. The hybrid scheme consists of a number Voltec a classic 1.4 petrol engine, which recharges the batteries - the shape of a "T" and 180 pounds heavier, placed under the floor - if the charge level drops below 25% for "supplies" the whole is not necessary to connect the electrical system.
The Ampera can be guided by choosing between four modes of use, the more the sport greener. Inside, apart from technological quirks (all instrumentation multi-color), one is struck by the cramped coupe-like glazing and the large space available, limited only in the trunk. The guide however is very natural and immediate, with no off or shaking when there is a transition between the two concentrations.
The electric minivan prototype as yet the role of the laboratory, pointing to a more understandable smear. Even the driving experience is rougher than the other two protagonists of the test, especially when analyzing the responses steering that does not provide adequate answers and proves rather inert to the smallest changes.
Far more interesting is the electrical functioning of the platform. The presence of an inverter makes it possible to restore electricity to the grid if he has in abundance, while the driver can set the charge for this to happen at certain times or when the network is powered by electricity generated from renewable sources.
The Meriva MeRegio was developed using government funds granted under the Plan Minimum Emission Region.
