Rooftop Solar and EV Batteries Could Supply 85% of Japan's Electricity Needs

What happens to EV batteries when they die? A surprising second life

When you think about the end of an electric vehicle’s (EV’s) life, what comes to mind? Maybe a worn-out battery tossed into a landfill. But the truth is far more nuanced—and a lot more hopeful. EV batteries don’t just “die”; they fade. And when they’re no longer strong enough to power a car, they often begin a second life. The EV battery lifecycle Electric vehicle batteries, most commonly lithium-ion, are designed to last between 8 and 15 years …

Rooftop solar and EV batteries could supply 85% of Japan's electricity needs

A new study led by Tohoku University has revealed that rooftop solar panels, when combined with electric vehicles (EVs) as batteries, could supply 85% of Japan's electricity demand and reduce carbon dioxide emissions by 87%. The research provides a promising pathway for Japan's local governments to achieve carbon neutrality by taking advantage of existing infrastructure—rooftops and vehicles—rather than relying solely on large-scale energy syste…

Japan could power 85% of its electricity with rooftops and EVs, study finds

A new study from Tohoku University has found that Japan could meet 85% of its electricity needs using just rooftop solar panels and electric vehicles (EVs) as home batteries. This approach could also cut the country’s carbon dioxide emissions by 87%, making it a promising path toward a greener future. Japan faces unique challenges in […] The post Japan could power 85% of its electricity with rooftops and EVs, study finds appeared first on Knowri…

As EV batteries retire, recyclers like Eagoal race to scale and standardize

By 2025, a wave of retired power batteries is set to hit China. According to data from the China Association of Automobile Manufacturers (CAAM), China has led the world in new energy vehicle (NEV) production and sales for nine consecutive years since 2015. Given that power batteries typically last around a decade, a surge of end-of-life batteries is now poised to enter the recycling stream. This represents not just a vast market opportunity, but…
