Hyundai Motor's battery subscriptions set to boost EV growth

Hyundai Motor Group’s battery subscription model for electric vehicles (EVs) is expected to significantly lower upfront costs and accelerate broader EV adoption across the nation, once the carmaker proves the project's economic feasibility, industry officials said Wednesday.

The automaker plans to launch the demonstration project in the first half of this year, targeting corporate taxi fleets whose vehicle warranties have expired. Once it proves successful, the firm will then expand the range of the service to individual EV customers.

The program centers on separating EV battery ownership from the vehicle. For example, the price of Kia’s EV6 for corporate taxi use dropped to 18.6 million won ($12,700) last year when the battery cost was excluded. Customers instead pay about 1.4 million won per month as a battery subscription fee, which the carmaker says is lower than the typical monthly cost of LPG fuel.

Hyundai Motor Group will operate the pilot service with five IONIQ 5 taxis driving in the Seoul metropolitan area. The carmaker will focus on assessing the economic feasibility of the subscription model under the real-world environment.

The initiative will be jointly operated by Hyundai Motor and Hyundai Capital. Drivers or fleet operators will own the vehicle itself, while Hyundai Capital retains ownership of the battery.

Industry officials said the key upside of the program is to reduce risks of battery degradation from the viewpoint of customers.

By shifting concerns over battery residual value from consumers to financial institutions, the model helps minimize uncertainty for buyers. In conventional EV ownership, declining battery performance directly impacts vehicle value, and replacement costs fall on the owner.

“The battery subscription model sounds unfamiliar to most Korean customers, but the program will be widely adopted once it proves to be more economical than expected,” an auto industry official said.

Chinese EV maker Nio has introduced a battery-as-a-service model that separates battery ownership from vehicle purchases, supported by a network of battery swap stations. Renault Group also previously offered battery leasing for its Zoe model in Europe, although it later reverted to bundled sales due to concerns over residual values in the used car market. Vietnam’s VinFast has similarly adopted a battery subscription strategy.

However, lingering questions remain over whether the total cost of ownership — including monthly subscription fees — will ultimately be lower than buying a vehicle outright.

Some also argued that the battery subscription model could offer Korean carmakers a way to defend against intensifying competition from ultralow-priced Chinese EV makers rapidly gaining ground in the local market.

“As Chinese EV makers intensify price competition and rapidly expand their market share, adopting the battery leasing model could significantly reduce upfront costs and enhance price competitiveness of homegrown EVs,” another official from the auto industry said.
