E-Taxi in the endurance test: DEKRA measures up to 97% of its battery capacity after 260,000 km
Six Jaguar I-Pace, used as taxis in Munich, were the focus of an investigation. The vehicles have been in operation since 2018 and have mileage ranging from just under 180,000 to more than 260,000 kilometers. The inspectors examined the so-called battery state of health, the 'State of Health'. The result is surprisingly positive: The values lie between 95 and 97 percent. Thus the data contradict a widespread assumption.
Battery reality instead of smartphone myth
“Many people, for example, transfer their experiences with smartphone batteries to the topic of electric mobility,” says Christoph Nolte, Executive Vice President and Head of the Service Division Vehicles at DEKRA. “They have experienced with mobile devices that after only a few years they have a noticeably lower battery capacity, and fear the same effect in electric vehicles.”
Measurements from more than 25,000 tests show a different picture:
“Our experiences with the battery quick test clearly show longer service lives. The drive batteries are overall very good. We also observe, even at higher mileages, in most cases a State of Health above 90 percent.”
The Munich field test provides the appropriate complement. The vehicles were not spared.
“We charged the vehicles on average about one and a half times per day, and not in a particularly gentle way, but always fully charged, in order to give the drivers the corresponding security with regard to the range. Our experiences with the electric vehicles are extremely positive,” says Gregor Beiner, Managing Director of the Munich Taxi Center.
The insight has consequences for fleet strategy.
“The batteries are very, very durable, and even more so with the safety margins that manufacturers build in, they keep the capacity for a very long time. That’s why we continued along that path,” said Beiner.
The company currently operates around 70 vehicles, a little over a third of them electric – with different brands. By 2029 the fleet is to be fully electrified.
Not all of this assessment comes without caveats. Degradation does not progress the same in every vehicle. Driving style, climate and charging behavior influence the development. The testing organizations also acknowledge outliers. If you are on the used-car market, you can therefore rely on independent battery tests, such as those carried out by DEKRA and other providers. They provide information about the current condition and help in evaluating residual values.
Usually a warranty up to 160,000 kilometers
Additionally there is a regulatory framework that limits risks. Manufacturers typically guarantee at least eight years or 160,000 kilometers on the battery. If the capacity falls in this period, through no fault of the owner, below 70 to 75 percent, replacement or repair provisions apply – up to the replacement of individual modules or the entire battery.
For the taxi trade, this means: The central technical concern loses its sharpness. The battery remains a cost factor, but it proves to be more robust in everyday use than many expected. This can already be observed in shift operation, especially in the taxi industry.
