V3G Supports V2H
Vehicle to Home V2H is a system that can supply power from the car to the home.
This is a specific version of V2L (Vehicle to Load) which can provide power directly from a vehicle to electrical appliances.
V2L connection to the car is via an adapter like in this video which comes with the vehicle.
Mobile Resource
V3G is most favourable when compared to unmanaged charging of EVs; it can reduce the need for grid-connected electrical storage capacity. The grid’s resiliency, nationally, is increasing due to diversified generation sources and technology improvements.
V3G can add to this resiliency by functioning as a mobile resource using new standard swap batteries. The battery capacity of an average EV today will power a typical home for three days; larger vehicles like buses can power larger structures for longer periods of time.
By deploying capabilities such as bidirectional power flow with V3G battery Stations can increase grid resilience. While there are significant savings in the total cost of operation of V3G community batteries, body corporates can have the ability to fund V3G Battery Stations via EUA’s (Environmental Upgrade Agreements) to advance Net Zero emissions.
The current price of an EV is significant; this premium, however, is expected to disappear with EUA funded V3G community batteries.
VPPs = Virtual Power Plants
VPPs connect neighbourhoods to a localized energy network that can operate independently of the mains supply for various periods. The localized energy network operates independently of the main supply to allow local energy sharing between households.
The VPPs are decentralized and owned, and run by each business entity.
VPPs can provide most, if not all, of our future energy needs.
TECHNICAL INFORMATION
Do most EV manufacturers have bi-directional capability?
Tesla has bi-directional capability but not activated yet.
If a car's V2G capability is activated during peak demand hours (when prices are highest), the owner could be eligible for payment for "demand response" services.
V2L = Vehicle to Load
V2L connection to the car is via an adapter like in this video which comes with the vehicle.
VPPs = Virtual Power Plants
VPPs combines several compatible technologies, including rooftop solar panels, electric vehicles, heat pumps and storage batteries, to harvest and distribute clean energy to the community intelligently.
Standards
Charging plugs, bi-directional capability and control systems all contribute to the emerging standards being agreed upon and developed.
Agreement Required
Standardization is Key
If every company used a different battery type, it would be both expensive and wasteful. However, if a battery in a docking station fits multiple applications, it becomes more viable.
Considering customer convenience, standardization of swappable batteries and wide adoption of battery systems is vital, which is why global manufacturers have agreed to form the Consortium.
Honda is working hard on standardization for customer eMobility solutions. So too is Gogoro in Taiwan and SunMobility in India. All of these are 48VDC, similar in capacity and size. V3G intends to bring these together under one size fits all.
