Electric car with 17 percent loss of capacity: Time bomb battery: Losing electric cars after three years of reach?-capacity
Mitsubishi The Mitsubishi I-Miev (identical with Peugeot Ion and Citroen C-Zero) can be bought since the end of 2010, has a range of 150 kilometers and costs 34 390 euros.

The Austrian ADAC measured the battery capacity in an electric car long-term test after three years. Result: It shrank by 17 percent – and thus also the range. Buyers of e-cars should therefore pay attention to the correct guarantees.

The lithium-ion batteries of electric cars lose significantly after three years. This can be concluded from a long -term test that the OAMTC Automoblic club – the Austrian ADAC counterpart – has carried out. The OAMTC examined an electrical Mitsubishi I-Miev from its own long-term test fleet. "In 2011, among other things, the reach of the I-Miev was first measured by the Rollen test bench of the Vienna University of Technology. Three years and 40.000 actual road kilometers later the test was repeated. The result: The usable battery capacity of the vehicle has dropped by 17 percent", So the automobile club.

All Stromer affected?

"This means that in everyday life you only get 90 instead of 108 kilometers before the battery has to be charged", So OAMTC expert Steffan Kerbl. The same picture results in the test of a fictional constant trip at 50 km/h, which is also carried out on the roller test bench. "Instead of originally 165, the range is only 137 kilometers after three years. Due to similar battery technologies, it can be expected that the loss of capacity in other manufacturers is similar", so guy.

Mitsubishi contradicts

Compared to the Austrian news magazine "format" a Mitsubishi spokesman was surprised by the test result. "At 100.000 kilometers driven is likely to have such a drop in performance, but not at 40.000", such a spokesman. So far, no complaints have been received from customers. "As soon as we discover abnormalities in charging capacity, we will follow the matter, of course, but that hasn’t happened yet", quoted "format" The speaker on. However, he admits that too many quick loads could be a cause of the loss of capacity.

A corporate spokesman also informed Site that the prescribed battery maintenance had not been carried out in the vehicle concerned. This assumes that an electric car will lose a maximum of around two percent battery capacity per year.

Guarantee ensures against loss of range

In any case, the guarantee conditions and maintenance instructions from the manufacturers should take a close look at for buyers of electric cars. After all, they have long since reacted to the problem and strive not to pass on the risk of capacity to customers. BMW, for example, gives a guarantee of eight years or 100 on the i3 lithium-ion battery of the i3.000 kilometers. Renault promises a free exchange for the ZOE in less than 75 percent of the original battery capacity, which shifts the risk of lifespan from the buyer to the manufacturer.

Tesla has only recently changed the guarantee conditions of its electric sedan model – in favor of the owners: from now on and also retrospectively for all models ever produced, the California manufacturer not only grants a guarantee of eight years, but also on the entire drive. And without a mileage.

  1. Truth is only what was measured,
    So don’t bore us with what your electronics shows! Neither is valid, … What is shown in consumption, but only the measurement! So: full fill up, write down these liters n i c h t, because unimportant, only km stand. Fuel again after some route; Is z.B. Was the speedometer difference 87 km u.There were 4.6 liters of space, that’s (100: 87) times 4.6 = 5.28 l / 100 km. In Bavaria it is said to be uncritical, like them: "Everyone praises their glump!". How do you want to attack the ADAC measurement (17 % less capacity)? Which is still good, because with every laptop it is much worse! Already there you can see that they have no idea about the reality of the Li-Akkus. "Never stayed there" -Nothing proves. Probably from Nissan for advertising here?

    1. Our Nissan Leaf has after 2 1/2 years and 46.000km a SoH (Status of Health) of 94.7% DH.: Remaining capacity. 2. We do not notice this in daily use, the ranges are still the same (is probably due to battery management). 3. We have never been left (not to be composed), the battery has not exploded or pipes (Upper Bavaria). Conclusion: Site is permanently busy writing the e-mobility. PS.: How many gasoline or diesel engines are after 30.000km defective? These engines are also subject to aging!

  3. Whether this is still worth it?
    Somehow this reminds of nuclear power plants: Ideally, they produce clean energy at low costs. But first of all, a huge investment is necessary, then the planned term is not observed and finally the dismantling devours enormous sums – not to mention the waste problem and security. Ultimately, the balance is financially and ecologically negative. – Until an electric car is on the street, it has already devoured huge amounts of resources and afterwards it takes a lot of effort to get rid of the problem. (Apart from the fact that these cars are actually at least in Germany "Coal car" would have to call it, because from that they relate their energy.)))

  4. For every electric engineer is
    The loss of capacity depending on the time in batteries is a truism. The same applies to photovoltaic systems. In the latter, depending on the manufacturer and the technology used, one can count on a performance loss of 50% in 10 – 15 years. Both techniques can only be regarded as replacement solutions for conventional energy sources as a striking quick shots. If you still have the immense cost for the construction, operation, entertainment and measures for network stabilization "Windmill" approaches, rising energy prices are justifiable. Why has you heard nothing or little about the development level of nuclear fusion technology lately? This seems to be the only viable path of energy generation and use for the future.

  5. "Time bomb" Is definitely the wrong one
    expression. Because such a thing would go up over time, while here it can be assumed that a time -conditioned pipe crepe can be assumed. And I also advise serenity. In the battery technology, a lot will happen until the mass use. What is installed today is actually yesterday from yesterday.

  6. The most important thing is missing
    It is nice if you have 8 years of guarantee without a mileage, but the battery is very crucial how much percent residual capacity can still be tolerable and when it is a deficiency.
