The service will initially cover intelligent V1G charging before Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) follow. The Hyundai Group will begin rolling out AllDayEnergy in the UK through the Kia app in the second half of this year, with plans to expand to Europe, the US, and Korea.

The V2X technology enables a bidirectional energy flow between an electric vehicle and the power grid. This means that an EV can function as a mobile energy storage system instead of merely consuming electricity while charging. Users can charge their vehicles during periods of lower electricity prices and later use the stored energy or feed it back into an external system when needed. Depending on the market and type of service, this can help manage charging costs, meet household energy needs, and participate in energy company programs.

What Comes Together under AllDayEnergy?

AllDayEnergy will bundle the following energy services:

  • V1G: Adjusts the timing of vehicle charging to real-time electricity prices, grid conditions, and customer preferences.
  • V2G: Enables an electric vehicle battery to feed energy back into the grid when needed.
  • V2H: Allows the energy stored in an electric vehicle battery to cover the household's electricity needs, including backup power during outages.

Hyundai has already developed and operated various V2X services in several regions. In Korea, a pilot project for V2G technology is being conducted in the special administrative province of Jeju. In the U.S., V2H services have been introduced to provide households with emergency power during events like major wildfires. In the Netherlands, the company has launched V2G and smart charging services that optimize vehicle charging based on dynamic electricity prices.
