Veicoli elettrici - mobilità - tecnologie - ambiente - energia rinnovabile. L'esaurimento delle risorse e le conseguenti ripercussioni politiche ed economiche rendono necessario ridurre la dipendenza dall'importazione di prodotti petroliferi e spingere quindi verso lo sviluppo di fonti energetiche alternative. I veicoli elettrici possono utilizzare tecnologie e risorse nel modo più efficiente.

Aptera Electric & Gasoline Hybrid.

The Typ-1 uses a commoditized, 'ruggedized' 3-phase motor controller designed for vehicular applications, and a 3-phase motor made for us by a company here in Southern California. The rear drive suspension, and the drive reduction, are all designed and made by Aptera. Since the Typ-1e (electric) and the Typ-1h (series plug in hybrid) have different battery needs, this may result in different battery manufacturers for the two models. The Typ-1e is designed to use a 10 KWh pack, while the Typ-1h uses a smaller pack. The cycles and DOD are different for both applications. The real deal about Aptera's Mileage. With the All Electric Aptera, it is very easy to figure out the mileage range. The mileage is determined by the distance you can drive, under normal circumstances, until the batteries are effectively drained. In the case of the first Aptera typ-1e, we have calculated the range to be about 120miles. With the Plug-in Electric Hybrid version of the Aptera(typ-1h) the mileage of the vehicle is difficult to describe with one number. For example, the Typ-1h can drive 40 to 60 miles on electric power alone. Perhaps for such a trip, the engine may only be duty-cycled for a few seconds or minutes. An asymptotic decaying exponential is an accurate way to describe the fuel mileage of the Typ-1h. For example driving say, 50 miles, one might calculate a MPG number that's 2 or 3 times higher, say, 1000 MPG. As battery energy is depleted, the frequency of the engine duty cycle is increased.

ma che schifo di macchina è?
questo attrezzo che prima di tutto è ibrido ha delle forme e degli optional che fanno sembrare l'elettrico un giocattolo per ricchi più che una realtà possibile.
