The Nissan LEAF was one of many first battery electrical automobiles of the trendy period. Gross sales started in Japan and the US in December of 2010. However the batteries in a few of these early automobiles suffered from untimely failure, notably in scorching, dry climates like Phoenix, Arizona. Not like most electrical automobiles, the LEAF battery is air cooled and doesn’t have a fan to help with cooling.
Effectively, as soon as the wackos on social media discovered about the issue, the web lit up with anti-EV FUD about how the batteries in electrical automobiles had been no good and wanted to get replaced after 2 years at nice expense. It’s an city legend that has been pushed vigorously by the fossil gas firms and the stooges they make use of.
Nissan obtained no credit score for redesigning the LEAF batteries to make them in a position to survive scorching, dry circumstances. They referred to as these second era battery packs the “lizard battery,” however the city legend refused to die.
Many will likely be amazed to be taught that Nic Thomas, Nissan’s advertising and marketing director for the UK, advised Forbes lately, “Virtually all the [EV] batteries we’ve ever made are nonetheless in automobiles, and we’ve been promoting electrical automobiles for 12 years. We haven’t obtained an excellent massive inventory of batteries that we are able to convert into one thing else,” he added. “It’s the exact opposite of what individuals feared once we first launched EVs — that the batteries would solely final a short while.”
Actually, many EV batteries might outlast the autos they’re put in in, then take pleasure in a second life in a stationary storage utility earlier than lastly being recycled, in response to EVANNEX. “On the finish of the automobile’s life — 15 or 20 years down the highway — you’re taking the battery out of the automobile and it’s nonetheless wholesome with maybe 60 or 70% of usable cost,” Thomas mentioned.
“It’s extra sustainable to take the battery pack out of the automobile after 20 years, recycle the automobile, and reuse the battery. By far the simplest factor to do is take the whole battery out of the automobile, put it in a delivery container in a rack, and plug that right into a photo voltaic farm.”
To this point, Nissan has collected solely a small variety of LEAF batteries from crashed autos or these with guarantee points and it has provided a few of them to suppliers of stationary storage. Thomas says that Nissan’s new manufacturing unit at present underneath building in Sunderland, England, will use EV batteries to retailer power from photo voltaic panels and wind generators.
Many customers have had the misfortune to have the battery of their laptop computer or cellular phone die after just a few years and so they suppose the identical have to be true of EV batteries. However the battery packs utilized in autos have subtle battery administration methods that continually monitor the well being and efficiency of the person cells. These digital methods hold the cells from overheating throughout charging, which helps to extend battery life. Most (though not the LEAF) have liquid cooling that additionally helps stabilize battery temperatures.
The longevity of batteries will not be excellent news for firms like Redwood Supplies which might be planning to recycle lithium batteries as soon as they attain the top of their helpful life. Earlier than they’ll ramp up, they may want a gradual provide of used batteries, and it could be some time earlier than that occurs. However to not fear. Battery recycling is coming.
Recycling consultants advised Forbes that the EVs bought in 2019 alone will finally generate 500,000 metric tons of battery waste. [“Waste” may be a misleading term. Most of the materials inside those batteries can be recycled into new battery materials.] The IEA says that by 2040, there may very well be 1,300 GWh value of spent batteries in want of recycling. Primarily based on Nic Thomas’ feedback, that estimate could also be too excessive. The excellent news is that battery recyclers say they’ll extract as much as 95% of the supplies inside these batteries and use them to fabricate new batteries.
The takeaway is that nobody is promising an EV proprietor won’t ever expertise a battery failure simply as nobody can say an driver won’t ever expertise an engine or transmission failure. However within the US, federal regulation requires all producers to guarantee the batteries of their electrical automobiles for 8 years or 100,000 miles. Which may be the perfect peace of thoughts there’s for many who are pondering of becoming a member of the EV revolution.
