Manufacturing new lithium-ion batteries in B.C. has turned out to be a bust, but a Metro Vancouver startup company has found a niche in repurposing used electric vehicle batteries for use in backup power and energy storage.

Coquitlam-based Moment Energy is in the process of building a production facility in Surrey to take used batteries, test and recondition them, then reassemble them as Lego-like components for 500 kilowatt-hour stationary power units, enough electricity to power the basic needs for up to 50 homes.

Those power units can then be plugged into utility grids to serve as backup power during outages, to store electricity generated by solar panels to be used at night, or shore up the overall electricity grid.

“This is about building the infrastructure needed to support the next generation of energy demand,” Moment Energy CEO Edward Chiang said.

The company is already working with customers ranging from YVR, which is using one of Moment’s shipping-container-sized units to help backup the airport’s EV charging network, to B.C. Hydro, which sees them as an option to give the grid a power boost at times of peak demand.

“We think their product can work for our customers,” said Kari Montrichard, a senior manager at B.C. Hydro. “We think what they’re doing is pretty cool.”

Moment isn’t alone in working on grid-scale battery systems. Vancouver-headquartered Invinity Energy Systems is doing so with a different battery technology called vanadium flow.

Moment, however, is using the previously untapped resource of used EV batteries taken out of vehicles for warranty issues, which actually still have a lot of life left in them.

“When they need to be taken out, they still have more than 80 per cent capacity to them,” Chiang said. “So let’s not landfill them, let’s not prematurely recycle batteries, let’s actually repurpose them for another 20-plus years.”

EV batteries are made up of hundreds of individual cells, and Chiang said there are often only a few with defects at the end of their life for EVs.

With reconditioning, batteries have “closer to 90 to 95 per cent life left,” he added. In repurposing, he argues Moment can create more affordable backup power storage than trying to use brand new batteries.

And with 100 million EVs on the road globally, Chiang reckons “there’s a massive amount of battery supply.”

“We’re really trying to solve this massive environmental issue of what happens to end-of-life batteries,” he added.

By comparison, while the company E-One Moli’s $1 billion proposal to make new batteries for commercial equipment at a factory in Maple Ridge stalled at the end of 2024, Moment expects to have its $10 million Surrey facility open and putting together their grid-scale batteries by the end of June.
