Hello.
Today, I will be posting about a bi-directional charging electric vehicle.

"V2X, have you ever imagined?"

It is a technology that enables electric vehicle power
to be used when household power supply is cut off during natural disasters
such as earthquakes or tsunamis.

But V2L is still beginning.
Automakers and countries around the world
are focusing their efforts on VxG and V2X development.

VxG, Using electric vehicle power as a demand resource

This is a business that connects electric vehicles
to the electric power grid and utilizes electric vehicle power
as a demand resource for smooth operation of electricity use caused
by a surge in electric power demand and natural disasters.
Although it is currently at the level of V1G,
many countries are working hard to develop V2G technology to commercialize it.

V0G Current charging method Instant charging as soon as the charger is connected
V1G Controlled direct charging Charge only when electricity rates are low and stop when electricity rates are high.
V2G Controlled bi-direct charging Charge when electricity is low and discharge when necessary
(When discharging, it will be refunded.)

V2X, Bi-directional charging technology

In the future, electric vehicles will be more than just a means
of transportation, but a running battery.

It will play a role in stabilizing the electricity demand
of the entire city by discharging the charge when it needs
to be charged and discharging when it needs to be discharged.

V2X will evolve into various types of technology,
and technology is being developed for connection
with many systems in addition to charging and discharging.

V2X Vehicle to Everything Connecting Electric Vehicles to Everything
V2G Vehicle to Grid Connecting electric vehicles to the power grid
V2V Vehicle to Vehicle The connection between electric vehicles and electric vehicles
V2L Vehicle to Load Connecting electric vehicles to external loads
V2H Vehicle to Home Connecting electric vehicles to the home power grid
V2B Vehicle to Building Connecting electric vehicles to systems inside buildings

When V2X technology is commercialized like this,
a connected world will unfold where not only electric cars,
but also smart buildings, smart homes, and smart cars are all connected.

As such, the electric vehicle of the future will be positioned as an axis
of a smart city that connects to all systems related to power demand
and flexibly charges and discharges as needed.
