run “to zero and [charging] back to 100 Percent” can lead to faster degradation, Case said. This is also true if you frequently expose them to the higher voltages of fast chargers, rather than charging them more slowly with the lower voltages typical of home chargers. But that data can be harder to come by, unless EV The drivers agree that it will be tracked.
Recurrent provides access to this more detailed data for the EV He noticed drivers subscribing their cars to his data collection fleet. “For those, we can really remove the uncertainty.”
Can battery data prevent used electric vehicles from becoming a market for lemons?
Lennart Hinrichs, vice president of marketing and strategic partnerships at Twaice, a Munich-based battery analysis startup, agreed that collecting more data from individual vehicles leads to more accurate and valuable insights.
““Stats-only” data can be helpful, he said, but it “comes with a number of disadvantages.” For example, statistics cannot capture which batteries have manufacturing defects or pinpoint those that are performing poorly due to improperly calibrated interaction with the rest of a vehicle’s systems.
More precise insights can emerge from one EV‘s onboard diagnostics and those embedded in batteries themselves, he said. Twaice works with a German testing laboratory MOT Rhineland to carry out a “Quick Test” using both data sources to derive a “specific and accurate health status of that battery,” he said.
Even more accurate assessments of battery health, as well as battery safety, can be made by retrieving the real-time data that modern electric vehicles are collecting and sending to the cloud, he noted. Twaice is working with German automakers to predict health EV Batteries to help them structure warranties and plan ahead for how many batteries they need to make to replace, for example, those that will go out of service years from now.
More accurate and verifiable data for used electric vehicles is important for automakers and fleet operators to create a “market for ‘Lemons,'” Hinrichs said. This term, coined by 2001 Economics Nobel Laureate George A. Akerlof in a 1970 Paper, describes markets where expectations of poor quality and a lack of information to prove otherwise depress prices and undermine incentives to improve traded products, such as defective or “lemon”, used car.
In a recent report with MOT Rheinland and Autovista Group, Twaice analyzed how verifiable battery health data could help 2.4 percent added value or about €450 ($468) per vehicle to the lower limit of the values for used electric vehicles, which otherwise lack data. That’s €4.5 millions for each 10,000 Second hand EV Transactions, to put it in terms, on a scale important to the automakers that handle residual values of vehicles for leasing structures, warranties, and other matters.
Automakers, fleet owners and lessors, used car resellers and other automotive industry players “trying to find more transparency about their value,” he said. “The beauty of it is that you get risk mitigation from a fleet management perspective – technical and safety risks, but also financial risks and guarantees, all of which are important,” he said.
But automakers don’t necessarily make that kind of in-depth analysis of battery health easily accessible to consumers, Case said. That’s especially true for earlier models of electric vehicles like the Nissan Leaf, which saw their own bout of negative publicity for batteries that were wearing out faster than automakers predicted.
Early Leaf owners came up with their own “Hacks” for it, like the Leaf Spy smartphone application, which pulled data from the vehicle’s on-board diagnostics port, he said. “But you have to have a PhD. chemical engineer to understand what that thing is telling you.”
There are good reasons to be cautious about sharing battery data, which is still fraught with some uncertainty, he noted. At the same time, car manufacturers and the entire automotive industry need to find ways to share as much data as possible in an easy-to-understand way to lay the foundation for healthy and growing usage EV Market.
In fact, California is already proposing rules on how battery health must be tracked and made available for used EVs, both for battery recycling purposes and for usage information EV markets, he said. “Ultimately, every part of the car ecosystem will change due to the transition from internal combustion engines to electric vehicles.”
Recurring work with AAA aims at this type of consumer education, he noted. Beyond the offer EV Owner of the company’s data collection and analysis, Recurrent also offers personalized tips for drivers on how to keep their battery healthy and “After all, they’re helping them sell this vehicle at a premium,” he said. After all, “Nobody grew up learning how to take care of themselves from their parents or grandparents EV.”
