How old electric car batteries could power the future | 24CA News

In a warehouse in Port Coquitlam, B.C., sits a big, blue metallic field that may assist save Canada’s power grids and stop folks from struggling sky-high electrical energy payments.

It’s an power storage gadget that its makers, Moment Energy, are calling “Flora.” What makes this unit particular is what’s inside. Powering it are retired batteries which might be now not adequate for electrical automobiles’ high-speed acceleration, however nonetheless have a whole lot of life left.

“These EV batteries have 80 per cent capacity left in them once they reach end-of-life. This makes them perfect for stationary energy storage applications,” mentioned Gurmesh Sidhu, one of many co-founders of Moment Energy.

The Vancouver-based start-up is harnessing the scraps of the electrical automotive revolution to energy factories, neighbourhoods and charging stations.

Think of the gadget as a large rechargeable battery; it may possibly retailer power from the grid or renewable techniques like photo voltaic panels, after which act as an influence supply when wanted.

The thought got here to Moment Energy’s 4 founders, Edward Chiang, Gabriel Soares, Sumreen Rattan, and Sidhu, whereas they have been finding out engineering at Simon Fraser University. During a challenge the place they have been tasked with constructing an electrical race automotive, they realized that the transition to EVs would result in a battery waste drawback.

“As we did more research, we realized there was a business opportunity here,” Rattan says.

Moment Energy has been testing its Flora prototype in quite a lot of environments and gathering information; it’s getting used to switch diesel-fuel turbines in distant areas, and to retailer renewable power from photo voltaic and wind farms.

Most just lately, they’ve teamed up with Hydro Ottawa to see if the gadget can complement energy in suburbs the place EV adoption is straining the native grid provide.

“By adding a battery, we can then charge it during a low-power time that would normally be unused power, and use the battery to provide excess power to these sites during the evenings when they’re charging all of these electric vehicles,” Sidhu mentioned.

Canadian cities and cities want extra power storage — and quick. The nation’s power demand is anticipated to surge by 50 per cent over the following decade, as extra automobiles and companies electrify, a current RBC report discovered.

The federal authorities has set an formidable obligatory goal for all new automotive gross sales to be zero-emission by 2035, sooner uptake than the U.S. and plenty of European international locations.

“That’s going to completely transform how our electrical grid at a city-level actually works,” mentioned Evan Pivnick, a program supervisor at Clean Energy Canada, a assume tank targeted on local weather and the power transition.

Ontario, the nation’s most populous province, may see electrical energy shortages as quickly as 2026, based on the identical report. That may trigger particular person and business electrical payments to balloon.

Moment Energy’s Flora system might be part of the answer. The unit is designed for industrial use to assist companies be extra “energy independent,” Rattan mentioned.

More EVs on the street additionally means extra retired batteries that might dwell out a second act. The common electrical automotive battery is anticipated to final between 10 to twenty years, longer than anticipated.

“The batteries themselves are lasting a lot longer than the car itself,” mentioned Steve Fletcher of the Automotive Recyclers of Canada. It’s been a couple of decade because the first fashionable EVs have been mass-produced, and Fletcher mentioned auto recyclers are simply now seeing these automobiles being introduced in.

“We’re seeing enough of them that it’s more than a trickle,” he mentioned.

At some level, as a result of efficiency points or time, all EV batteries will must be changed. But they’re too precious to easily throw away. One possibility is to recycle them, which might reintroduce the dear minerals within the batteries again into the provision chain. But new analysis means that re-use is one other viable route.

“We believe in using resources to their full potential. They have so much life left in them it would be a waste to not re-use them,” Rattan mentioned.

EV batteries are costly and useful resource intensive to make. So, identical to the sturdy auto components market that exists at the moment, a brand new trade round second-life makes use of for these batteries is taking form.

Entrepreneurs and automotive producers are growing artistic methods to increase the lifetime of outdated EV batteries. Nissan has used its outdated LEAF batteries to energy streetlights in Japan. General Motors has retrofitted Chevrolet Volt batteries to be able to supplying properties with backup energy. B2U Storage Solutions within the U.S. is utilizing EV batteries to retailer extra energy from California’s photo voltaic farms.

In Canada, Montreal-based start-up EVB360 is remanufacturing LEAF and Volt batteries to create power storage gadgets that might be utilized in off-grid conditions.

Martin Ménard, vice-president of operations and provide at EVB360, mentioned he’d prefer to see the know-how utilized in growing international locations the place communities don’t have entry to electrical energy.

“That’s where people need energy most in the world,” he mentioned. “Giving communities clean and constant energy will allow them to grow.”

Ménard mentioned they’re testing a prototype with an current photo voltaic panel system in Dakar, Senegal.

Finding new makes use of for spent EV batteries lessens their total emissions by extending their life. Researchers at Cornell University discovered that the carbon footprint of those batteries may be diminished by as much as 17 per cent if they’re reused earlier than being recycled.

Re-use also can decrease the price of power storage gadgets. In 2025, second-life batteries could also be 30 to 70 per cent inexpensive than new ones, based on a report from the consulting agency McKinsey. But as battery manufacturing ramps up, these price financial savings may drop to 25 per cent by 2040.

Based by itself market evaluation, Moment Energy says its gadget is 25 per cent cheaper than different industrial storage gadgets.

EVB360’s unit will retail for CAD $10,000 to $12,000, which Ménard mentioned is cheaper than power storage items that use new batteries. Their gadget might be used as supplementary energy for particular person residences.

Both EVB360 and Moment Energy are presently looking for certification for his or her new know-how so as to have the ability to promote it on to prospects. Batteries, in spite of everything, are fire-prone items.

It’s an rising area with vital potential, however extra analysis is required to evaluate how rapidly retired batteries degrade in re-use purposes. Based on testing information, Moment Energy estimates their gadget will final seven to 10 years.

“We’re assuming a minimum of seven years, but it could be much longer than that,” mentioned Rattan. “We have a seven-year warranty.”

Moment Energy will get its batteries instantly from automotive producers. They then check every module to ensure it’s secure and dependable earlier than including it to certainly one of their Flora gadgets.

Because the know-how is so new, little real-world information exists to help claims that these refurbished batteries will final lengthy sufficient to compete with new items and the recycling trade.

“The economics for second life will need to be greater than the economics of recycling,” mentioned Pivnick. “It’s going to be a competitive space.”

Evolving battery know-how may additionally hamper the re-use area. Lithium-ion batteries are the favorite for automobiles at the moment, however already automakers are experimenting with different chemistries similar to stable state.

All innovation comes with uncertainty at first. Where we’re with electrical automobile know-how is equal to the Nineteen Twenties and Thirties combustion-engine automotive, mentioned Pivnick.

“There’s a lot of innovation still out there.”
