One of the many false claims EV critics, trolls, and FUD-whackers make is that somehow EV batteries just magically and suddenly stop working after a while. Their falsely claimed “die-off distance” might be when the EV has about 50,000 or 70,000 miles. A second part to their false claim about … [continued]
Researchers are in hot pursuit of magnesium batteries to fill the growing need for low-impact utility scale energy storage technology.
We were totally excited on October 22, 2019 when we drove our Tesla Model 3 Long Range away from the Tesla Salt Lake City Delivery Center. We’ve just passed our 3 year anniversary! Our odometer as I write this reads 80,821 miles. I wanted to determine how much battery degradation … [continued]
Researchers at Tohoku University have unearthed a means to stabilize lithium or sodium depositions in rechargeable batteries, helping keep their metallic structure intact. The discovery prevents potential battery degradation and short circuiting, and paves the way for higher energy-density metal-anode batteries. Courtesy of Tohoku University Scientists are ever-seeking to develop … [continued]
Anyone who has driven an electric vehicle like a Tesla knows about the barrage of incoming questions from uninformed members of the public. YouTuber and friend of CleanTechnica Tesla Raj took to the ‘Tube to address a few common misconceptions about electric vehicles and, more specifically, Teslas.
CleanTechnica and EVObsession appreciate the innovative, including early EV adopters. Although we support the wonders of icons such as Elon Musk and his oh so Zen Teslas, we also value every other EV. Being an old organic farmer raised in innovative cultures of do-it-yourself lifestyles, I certainly value action-oriented individuals such as Sam Elliot. Sam is one of the doers not afraid of smaller range EVs to live the zero-emissions way of life. His innovative work helping him to use a smaller-range EV without that any range anxiety is one to be validated and cheered.
The Nissan LEAF is infamous for its battery problems. It started with the fast degrading 24kWh battery in the original 2010 Nissan LEAF. That battery was not up to the hot conditions of US Southwest states. It was replaced by a battery with a different chemistry, the 24kWh “lizard battery” in 2014. In 2015, the model year 2016 (MY2016) LEAF got a slightly larger 30kWh battery option. In the MY2018 Nissan LEAF, an even bigger 40kWh battery was offered.
A study conducted by Nissan and Enel shows that electric car owners can get paid more than $1,500 a year if they participate in a V2G program and that doing so actually extends battery life.
The largest single chunk of the cost of a Tesla is the battery, which also poses a single point of failure risk for Tesla owners. Buyers are typically not worried about an event-based failure, even though fires could certainly be a concern, but rather about the degradation of the battery over the life of the vehicle. With EV drivetrains expected to last much longer than their fossil fuel–fired counterparts, the life expectancy of the battery becomes a looming maintenance expense waiting to hit and has everyone asking, “How long will it last?”
A couple of weeks ago, I wrote about some interesting comments Tesla CTO JB Straubel made regarding vehicle-to-grid technology and using old EV batteries for stationary energy storage (for homes or the grid). There was a tidbit in there that I wanted to further highlight on its own, since it’s … [continued]
