Most Used Electric Car Buyers Have No Way To Confirm Vehicle Battery Health

from the this-could-be-a-problem dept

As we make the shift from gas to electric vehicles, there are a few issues we still haven't really paved the way for. One is the fact that, with gas taxes being the primary way we fund highway infrastructure, we need to develop alternative infrastructure funding (not a topic that tends to get priority in a hype and flash-obsessed culture, as John Oliver has been quick to remind everyone). The 18.4 cents a gallon federal gas tax hasn't been raised since 1993, and the Congressional Budget Office says that if the funding system doesn’t evolve by 2030, federal transportation funding will exceed its budget by a cool $188 billion.

The other problem, highlighted by Aaron Gordon at Wired, is that used car buyers and sellers currently have no way to confirm the battery health of a used electric car. Given the used car market is twice as big as the new car market, you can probably see how this could become a notable problem. Especially given that the battery health meter on most of these vehicles can be reset, allowing the seller of the car to effectively lie to buyers about how much life the battery has left:

"Churchill noticed something was wrong on his drive back home. When he left, the car estimated it had 80 miles of range. By the time he finished his 25-mile commute, it said it had 30 miles of range left. And in the next few days, Churchill said the battery health meter lost two bars. When he called the dealer to complain, he was shuffled between departments and ultimately ignored.

After doing some research, Churchill learned the battery health meter can be reset using a car diagnostic tool. After resetting, the meter will display all 12 bars for a short period before recalibrating after some use, just as Churchill's did. During this time, the car is essentially lying about its battery health."

According to the Bureau of Transportation Statistics, there are 17 million new cars sold in the US every year, compared to 40 million used vehicles. Currently only the Nissan Leaf even has a battery health meter customers can view. Every other electric vehicle currently on the market restricts that information to proprietary devices that typically only the sellers or dealers have access to, which will likely in time tether this whole discussion to the right to repair debate, and the obnoxious ways car makers restrict your ability to repair (or even have transparency into) things you own.

While the California Air Resources Board is cooking up a set of rules (pdf) aimed at protecting consumers from fraud on this front, the vast majority of states are... not doing that. What could possibly go wrong?

    When the port approved SpaceX leasing the Bethlehem Steel acres of Terminal Island in 2016, lots of history popped up from 50 years ago. Trust the web to be consistently sanitized, this is all I find Every old gas station in the LA basin has or had hundreds of thousands of dollars of ground-water scavenging equipment running for years and years. Los Angeles won a suit (based of an 1830's agreement) against Burbank, Dizny, Glendale, Universal City, et. al. in the 1990's, and pumped a 3foot tall 350ft wide wall of water out of Wilmington, 12 months for many years, cleaning everyone's aquifers. Non-monetised petroleum costs. We have all fallen down a well, and no one understands Lassie
