ISO 15118 communication standard (Plug&Charge, V2H, V2G)
What is this standard?
The ISO15118 standard is a communication standard between vehicle and charging station. It describes the physical requirements and protocols, as well as the supported functions of this interface.
The functions primarily include:
Charging releases for Plug & Charge
Charging management for charging and discharging vehicles (unidirectional charging, bidirectional charging for V2H and V2G)
What is the aim of the standard?
The aim of this standard is a homogeneous implementation of the vehicle and its storage in the public grid or in the home system as a storage unit. in the long term, it should be possible to use the vehicle storage to stabilize the public grid (V2G = Vehicle to Grid) or as a home storage solution (V2H = Vehicle to Home).
Is this already a reality?
The use of this standard is still very limited. Various charging hardware and vehicle manufacturers are currently conducting tests on this topic in order to coordinate and further develop communication. Some plug & charge solutions are already in operation in real life but are not yet very widespread.
V2G and V2H applications are already partially supported by DC charging stations.
The offer for V2G and V2H on the part of AC charging stations is currently still very limited or non-existent due to the unavailability of the necessary equipment on the part of the vehicles.
However, the first vehicle manufacturers have already announced vehicles that will have the technical equipment.
However, none of these vehicles can currently be purchased on the market. (State on 16.05.2025)
What does this mean for your Pico charging station?
Your Pico charging station is fully prepared for the future. A software update will suffice to activate the functions on your Pico and we are currently working intensively on the implementation of the functionalities.
