Auto aankopen, totaalkost op 4 jaar/60.000 km
Met zo een korte gebruiksduur en zo weinig kilometers haal je natuurlijk een grote kostenfactor uit het plaatje: de vervanging van de batterijen voor iemand die het zich niet kan of wil veroorloven om een auto al zo vlug te verkopen.
Tja, de ADAC moest ergens een lijn trekken, Tesla model S is er ook nog maar net bij want die werden pas halfweg 2011 geleverd (wslk een extrapolatie voor de Dual Drive modellen)
Tesla geeft overigens 8 jaar garantie op het accupack/laadsysteem, daarnaast nog altijd gegarandeerd 8 jaar lang gratis laden(vanaf
EZ) op hun superchargernetwerk.
Ooit zal dat wel veranderen, maar diegene die hem in 2015 kreeg is al zeker tot 2023.
Het toekomstig model III (35000 €) zou daar ook nog van kunnen profiteren
volgens Tesla en die komt vermoedelijk einde 2017 op de markt.
Van einde accupack gesproken (ttz minder rijbereik#) is er voor de lichte Tesla Roadster (EZ vanaf 2008) een update 3.0 voorzien - prijs voorlopig
? - maar in elk geval een groter accupack van 70 kWh -
stand kwaliteit* Tesla S - ipv oorspronkelijke 54 kWh en nog talrijke verbeteringen voor een nog langer rijbereik, zelfs verder als de huidige Tesla Model S met 85 kWh accupack.
Voor de Tesla S is ook ooit zo´n navenante update voorzien, gis ik toch.
Het accupack-systeem van de Tesla S zijn wel duurzamer aangezien 3-4 jaar evolutie tussen de eerste roadsters en model S, dit is ook in duurzaamheidstesten# gebleken:

The study concluded that the typical Roadster would still have 80-85 percent battery capacity after 100,000 miles (though some Roadster owners have lost much more). The Model S has a superior battery management system# to the one found on the Roadster, so it stands to reason that battery degradation should be even less#.
And according to a Dutch engineering professor, it is. Based on 84 data points from the 85-kWh version of the Model S and six from 60-kWh cars, the study concludes that the Model S will retain about 94 percent of its capacity after 50,000 miles, with losses thereafter shrinking to about 1 percent per 30,000 miles. That means that after 100,000 miles, the typical Model S is projected to retain about 92 percent of its battery capacity and range.
Tom Saxton, chief science officer for Plug In America, says a Model S85 is projected to retain about 90 percent battery capacity until 86,000 miles according to Green Car Reports. According to Saxton’s data, the S60 version, whose smaller battery must undergo more charge/discharge cycles to travel the same distance, retains 90 percent capacity to about 67,000 miles. The high-mileage car in the ongoing study had 92,000 miles as of last summer and still retained 92 percent of battery capacity.
While there is no data or scientific evidence, many electric car owners believe that not charging their battery to 100% capacity regularly prolongs battery life. The same goes for not overdoing it with high powered DC fast chargers. As the saying goes, it’s true if you believe it’s true.
Hangt natuurlijk veel af hoe je met de auto omgaat, ttz in dit geval het duurzamer laden van het accupack, bij laptopinstellingen is dat ook niet veel anders.
Bron update 3.0:
http://www.teslamotors.com/blog/roadster-30
The Roadster 3.0 package applies what we've learned* in Model S to Roadster. No new Model S battery pack or major range upgrade is expected in the near term.
Battery technology has continued a steady improvement in recent years, as has our experience in optimizing total vehicle efficiency through Model S development. We have long been excited to apply our learning back to our first vehicle, and are thrilled to do just that with the prototype Roadster 3.0 package. It consists of three main improvement areas.
1. Batteries
The original Roadster battery was the very first lithium ion battery put into production in any vehicle. It was state of the art in 2008, but cell technology has improved substantially since then. We have identified a new cell that has 31% more energy than the original Roadster cell. Using this new cell we have created a battery pack that delivers roughly 70kWh in the same package as the original battery.
2. Aerodynamics
The original Roadster had a drag coefficient (Cd) of 0.36. Using modern computational methods we expect to make a 15% improvement, dropping the total Cd down to 0.31 with a retrofit aero kit.
3. Rolling Resistance
The original Roadster tires have a rolling resistance coefficient (Crr) of 11.0 kg/ton. New tires that we will use on the Roadster 3.0 have a Crr of roughly 8.9 kg/ton, about a 20% improvement. We are also making improvements in the wheel bearings and residual brake drag that further reduce overall rolling resistance of the car.
Summary
Combining all of these improvements we can achieve a predicted 40-50% improvement on range between the original Roadster and Roadster 3.0. There is a set of speeds and driving conditions where we can confidently drive the Roadster 3.0 over 400 miles. We will be demonstrating this in the real world during a non-stop drive from San Francisco to Los Angeles in the early weeks of 2015.
Appointments for upgrading Roadsters will be taken this spring once the new battery pack finishes safety validation. We are confident that this will not be the last update the Roadster will receive in the many years to come.
Test prototype Roadster 3.0 LA-San José 340 miles of ~ 547 km reikwijdte met 32 km range-reserve over:
http://www.teslamotors.com/blog/roadster-road-trip-update-san-jose-los-angeles-single-charge
As we announced in December, the Roadster 3.0 upgrade will feature enhancements in battery cell technology, aerodynamics, and rolling resistance. These modifications should boost the Roadster’s range by 40 to 50%.
For our first test outing, we evaluated the prototype package on a historic route down the I-5 from our first Tesla store in San Jose to the Santa Monica Pier (via the Tesla Store on the 3rd Street Promenade), a distance of approximately 340 miles.
The trip was smooth, with no disruptions. On the highway, we set cruise control to stay right around the speed limit. We turned on the heater for a 40-minute stretch going over the Grapevine. And less than six hours from leaving San Jose, we pulled into the Santa Monica Pier, with 20 miles remaining in the battery pack.
The drive is a positive step in the evolution of the Roadster. Next up, we'll apply our learning from the trip to further development work on the vehicle.
Als men nu hypothetisch 8 jaar rijdt aan 20.000 km/jaar of 160.000 km met een reikwijdte of accucapaciteit die tot in de laatste jaren verminderend tot pakweg 85 à 90 % valt dat nog best mee, wie weet hangt men er nog 2 jaar bij. "Normaal accucapaciteitsverlies" valt natuurlijk niet onder garantie dat is "normale slijtage".
