Present battery swap networks like Nio’s have principally included a single firm’s gear, giving the producer management over the automobile, battery, and swapping gear. That’s as a result of one of many keys to creating battery swapping work is fleet commonality—a base of many automobiles that may all use the identical system.
Luckily, supply drivers have shaped one thing of a de facto fleet in New York Metropolis, says David Hammer, co-founder and president of Popwheels. Roughly half of the town’s 60,000-plus supply employees depend on e-bikes, based on metropolis estimates. Lots of them use bikes from a model known as Arrow, which embody detachable batteries.
Comfort is essential for supply drivers engaged on tight schedules. “For lots of people, battery charging, battery swapping, it’s simply know-how. However for [delivery workers], it’s their livelihood,” says Irene Figueroa-Ortiz, a coverage advisor on the NYC Division of Transportation.
For the New York pilot, Popwheels is constructing battery cupboards in a number of areas all through the town that can embody 16 charging slots for e-bike batteries. Riders will open a cupboard door utilizing a smartphone app, plug within the used battery and take a recent one from one other slot. Based mostly on the corporate’s modeling, every cupboard ought to be capable to help fixed use by 40 to 50 riders, Hammer says.
“Possibly it results in a fair bigger imaginative and prescient of battery swapping as part of an city future,” Hammer says. “However for now, it’s fixing a really actual and speedy drawback that supply employees have round how they will work a full day, and earn an inexpensive dwelling, and do it with out having to place their lives in danger for battery fires.”
A rising drawback
Lithium-ion batteries energy merchandise from laptops and cellphones to electrical automobiles, together with vehicles, vehicles, and e-bikes. A serious good thing about the battery chemistry is its vitality density, or means to pack loads of vitality right into a small container. However all that saved vitality will also be harmful.
Batteries can catch hearth throughout charging or use, and even whereas being saved. Usually, fires occur when temperatures across the battery rise to unsafe ranges or if a bodily drawback in a battery causes a brief circuit, permitting present to circulation unchecked. These components can set in movement a harmful course of known as thermal runaway.
Most batteries embody a battery administration system to manage charging, which prevents temperatures from spiking and sparking a hearth. But when this technique malfunctions or if a battery doesn’t embody one, charging can result in fires, says Ben Hoff, who leads hearth security engineering and {hardware} design at Popwheels.
