Carry heavy batteries with large autonomy for getting around town is against efficiency.
Elon Musk appears to look favorably on the solution proposed by the Nomadic Power to combine Nomadic Power extenders rental trailers autonomy to long commutes and the use of integrated battery for the city.
Nomadic Power is a German company which we have spoken on other occasions. Funded by the European Commission this company developed a battery trailer that serves as extender equipped with a 85 kWh battery capable of delivering up to 500 kilometers range autonomy. Through a rental system users dispondrían stations in tow to change your battery once consumed
Again statements of Elon Musk, CEO of Tesla, in this case, on whether to incorporate electric cars very heavy batteries, criminalizing its weight and therefore its consumption and efficiency, or the logical it is to try to carry at all times the battery capacity required for the movement that is to be performed.
CEO of Tesla said he was thinking about the concept of mobile batteries as a range extender. In this discussion he mentioned Nomadic Power could have its trailer range extender in the main arteries of the country. So an owner of an electric vehicle that would travel 500 kms, would hook one of these trailers to the outskirts of the city, where he would leave for, from there, move freely through your car battery. The CEO of Tesla, Elon Musk, showed how absurd it is to move all that weight when driving over short distances, as well as paying a very high price for them at the time of purchase.
Tesla is intended to strike a reasonable balance between price and performance of their electric cars and therefore has recently adjusted the capacity options Battery Tesla Model S between 400 and 500 kilometers supported by a network of fast charging .
