While electric cars are great at abbreviation emissions, they aren’t a absolutely absolute solution. With the rise of EVs, the world will have to deal with an influx of worn out batteries creating a new waste problem. But thankfully, scientists are already coming up with ways to tackle the issue.

Researchers from Warwick University’s accomplishment arm WMG have developed a new system for testing the abeyant life of used Nissan Leaf batteries to actuate whether they should be reused, recycled, or disposed of, Warwick University writes.

Importantly, the new action is far faster than accepted methods. Allocation a batch of array modules can take just three minutes, compared to the three hours of antecedent methods. Advisers say the new allocation action is far cheaper than accepted methods, too.

According to Warwick University, advisers were able to grade and accommodate 50 buzz Nissan Leaf batteries to bear a accumulator accommodation of 1MWh. Or in other words, the boffins found a way of reusing EV car batteries to store enough energy to power about 1,000 kitchen kettles for half an hour.

A very useful development

When electric cartage reach the end of their life, the array packs can still be in pretty decent condition. Electric motors might fail, other parts of the car might get damaged in a crash, but the batteries might still be in good alive order.

The advisers expect array packs to be able to store 70-percent of their aboriginal accommodation by the time the rest of the car is asleep or needs retiring. That’s a lot of abeyant to just throw away, waste, or even break up for parts.

Indeed, as Professor David Greenwood from WMG says: “A second life for batteries improves both the ecology and bread-and-butter value we draw from those assets before they need recycling.”

While these “second life” array packs might not be good enough to meet the demands of an EV anymore, they could be used in other applications.

They could be installed in homes to store energy from solar panels, like the Tesla Powerwall. They could be used at wind farms to store energy when there’s lots of wind, so that on less windy days there’s still a source of green, renewable energy.

By 2025 Nissan expects there to be tens of bags of electric cartage on the road which accommodate end of account batteries. It’s important that these assets are recycled.

With its new allocation process, the Japanese car aggregation expects to be able to reuse the vast majority of array packs used in EVs in Europe.
