Hyundai Motor to Include V2X Technology for Their EVs

V2X Technology

Hyundai Motor is developing V2X technology to further develop the usability of renewable energy sources and reduce strain on local electricity networks.

Hyundai Motor is expanding its offer of energy solutions by developing Vehicle-to-Everything (V2X) technology. V2X is a technological innovation that further integrates renewable energy and battery electric vehicles (BEV) into society.

One of these technologies is Vehicle-to-Grid (V2G). This technology enables energy that is already stored in the battery packs of BEVs to be provided to an electricity network, also known as a ‘grid’. On top of stabilising the grid, the energy stored in BEVs feeds the grid to assist in managing energy demand during peak times and emergencies. Hyundai is currently running two V2X pilot projects in the Netherlands and Germany featuring fleets of modified IONIQ 5 models that are equipped with customised V2G-capable software.

The energy landscape will drastically change due to this integration of BEVs into the grid. Not only will BEV owners have the opportunity to contribute actively towards the stabilisation of their local grid, but V2G will also be a strong contributor to a stabilised renewable energy provision. The grid directly distributes renewable energy from solar or wind power to users. With the application of V2G, renewable energy can be stored in BEVs and fed back to the grid when it cannot be generated, for example at night or when there is no wind, or at peak times.

As V2G technologies benefit not only BEV owners but also entire societies sharing an energy system, this initiative falls in line with Hyundai’s “Progress for Humanity” vision.

V2G to better manage energy demands

To be able to support V2G, BEVs must be equipped with the correct hardware, including a bidirectional onboard charger that allows energy to flow to and from the battery pack, and appropriate software that controls this discharge.

This bidirectional energy transfer promotes more active electricity consumption as BEVs can still serve a purpose outside of passenger transportation. Since only a certain percentage of battery capacity is utilised for driving purposes, the remaining stored energy can be fed back to the grid to be used by local energy distribution utilities.

As countries are adding more variety to their energy mix to include more renewable energy sources, V2G technology will help reduce the impact of climate change. Instead of relying on reserve power plants, which generate more air pollution, the grid can depend on the energy stored in BEV battery packs generated from solar or wind power.

The benefits of V2G

As a convenient and cost-efficient way to locally store and share energy, V2G offers numerous benefits for BEV owners, the grid, and the environment.

When V2G technology balances the grid, everyone benefits. During high-peak times when large amounts of energy are drawn from the grid, BEVs can return energy to the local infrastructure and help even out the demand. Owners can then recharge their BEVs at a lower cost during off-peak hours.

According to business models that are currently under review, users can provide energy from their BEVs into the grid. Because grid services are used more efficiently, V2G results in savings for operating electricity systems, which are then passed on to the user. Additionally, the entire system can reap economic benefits from these reduced power system costs because V2G offsets capital and operational costs.

The implementation of V2G technology also accelerates the decarbonisation of the power system. Electricity generated from renewable energy sources, such as solar or wind, can be stored in BEVs. Overall, this will reduce the amount of carbon dioxide emissions from the power system because it will lessen the dependence on fossil fuels.
