Selex Motors bets on battery swapping to lead Vietnam’s EV revolution
On July 20, US Secretary of State Janet Yellen visited the factory of a Vietnamese EV manufacturer. It was not VinFast but Selex Motors, which builds electric bikes and batteries as well as operates a network of homegrown battery-swapping stations.
Before Yellen’s visit, Selex Motors was relatively under the radar.
“We don’t really spend money on marketing,” co-founder and CEO Nguyen Nguyen tells Tech in Asia in a recent interview. “We also don’t raise funds just to boast about it.”

Following his mechanical engineering studies in the US and a stint at a Vietnamese state-owned corporation, Nguyen founded Selex Motors in 2018.
The startup was born out of his strong conviction that Vietnam eventually has to do something about the 50 million gasoline motorbikes zigzagging and polluting the streets. But how can the country electrify its roads when EVs are costly and time-consuming to charge?
Nguyen believes that untethering the battery can potentially make electric two-wheelers (2W) more accessible. “Eventually, we’ll need to treat batteries like utilities. They need to be part of a separate service,” he adds.
‘Battery vending machines’
At first glance, a Selex Motors battery-swapping station resembles a vending machine. It has 19 compartments but only holds 18 batteries at maximum, leaving a slot for used ones. Drivers unlock the machine with the Selex Motors app and grab a fully-charged battery within two minutes.

For now, these stations are mostly used by delivery drivers. This represents how Selex Motors’ strategy differs from its local EV peers.
Instead of targeting premium customers like Dat Bike and releasing new models quickly like VinFast, the startup currently focuses on the B2B segment almost exclusively.
“For delivery workers, time is money. They can’t afford to wait several hours to charge their batteries for a 200- to 300-kilometer daily trip,” Nguyen says.
Some of its notable B2B partners are Grab, Lazada, and Gojek. These firms either buy Selex Motors’ EVs – which it says can carry up to 225 kilograms of cargo – or provide financial incentives for drivers to purchase them.
