  • VW Battery Packs

    For the past 50 years, the German auto industry has enjoyed quite the roll of growth and success in the U.S., built largely on its expertise with one specific technology: the internal combustion engine. But now the importance of that advantage is fading, with electric cars on the rise and the highest-value component within them the battery pack. Increasingly, companies with headquarters in South Korea, Japan, and China—not Germany—have taken the lead not just on cells and chemistry but in the design of modules and sometimes the entire pack architecture. Meanwhile Volkswagen, for...

    Volvo reuses bus batteries for solar storage

    As solar installations ramp up and electric vehicles have been on the market for a few years, automakers are starting to look for ways to get more life out of old electric-car batteries, repurposing them for stationary storage. And if you're going to use vehicle old batteries for storage, you might...

    VW confirms it’s planning for solid-state batteries by 2025

    Solid-state batteries sometimes sound a bit like the missing link that would punt electric vehicles soundly into mainstream acceptance. The list of potential virtues for solid-state tech, which would replace the polymer/gel electrolyte commonly used in lithium-ion cells with a solid one, is...

    Some Chevrolet Bolt EVs get new battery pack for sudden loss of power: here's why

    It's every electric car owner's nightmare: the car indicates that remaining range has suddenly plummeted to zero, the battery pack stops providing current, and the car won't run. For some 2017 Chevrolet Bolt EV drivers, that scenario has happened in real life. The problem has resulted in a program...

    Nissan Leaf refurbished batteries offered for older electric cars, in Japan

    With more than 300,000 Nissan Leaf electric cars on the road, some more than six years old, battery degradation is becoming more and more of an issue. The different rates of capacity loss are a topic of much discussion among Leaf owners, but it now seems likely that Nissan's choice of passive air...

  • 2016 Nissan Leaf SL, Hudson Valley, NY, Dec 2015

    The Nissan Leaf, at least for the moment, remains the highest-volume electric car produced in history, with more than 300,000 sold. One of the measures that kept its cost down was the use of passive air cooling for its battery pack, rather than the pricier liquid cooling used by other makers to keep battery temperatures within limits. Nissan has already changed the cell chemistry in its batteries once, switching in 2015 to a so-called "lizard cell" said to be more resistant to degradation caused by very high temperatures.

    Silicon anodes to boost lithium-ion battery capacity within a few years

    The main impediment to mass electric-car adoption is price, and the driving force behind that is the cost of lithium-ion battery cells. The performance of those cells improves at about 7 percent a year, give or take: Either the same cell costs 7 percent less after a year, or a carmaker gets 7...

    The battery packs of most modern electric cars are far different than those in your mobile phone or other portable devices. In most cases, they include hundreds or thousands of cells, arranged into modules, and usually surrounded by channels containing liquid coolant to keep the battery in its...

    BMW partners with Solid Power to develop solid-state cells for electric cars

    While lithium-ion cells have powered all but a handful of plug-in electric cars since 2008, carmakers have looked further down the road toward solid-state battery cells with an eye toward launching them sometime during the 2020s. On Monday, BMW Group and Solid Power announced that the two companies...

    Hyundai believes electric-car battery prices will stop falling by 2020

    The automotive business is one that turns raw materials into highly complex finished goods. When the prices of key commodities—especially raw materials—rise, everything downstream in that process becomes more expensive. That's Hyundai's concern over battery prices from 2020 onward, as...

    For the 20 years since the introduction of the Prius, Toyota has enjoyed the first-mover advantage in hybrid cars, and leveraged those green credentials to boost public perception of its brand as a whole. But Toyota has yet to mass-market a battery-electric vehicle in the U.S., as Nissan has done with the Leaf. Toyota executives have consistently said hydrogen, not plugging in, is the best technology for zero-emission vehicles.

  • European Union battery alliance announcement

    As it stands today, Asia dominates the production of electric-car battery cells globally, with Japanese and Korean companies representing the bulk of the industry outside of booming Chinese makers.
