This document furthermore defines requirements of wireless communication for both conductive charging and wireless charging as well as communication requirements for automatic connection device and information services about charging and control status.
The purpose of this document is to detail the communication between an electric vehicle communication controller (EVCC) and a supply equipment communication controller (SECC). Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between the EVCC and the SECC (see Figure 1).
This document defines messages, data model, XML/EXI-based data representation format, usage of V2GTP, TLS, TCP and IPv6. These requirements belong to the 3rd until the 7th OSI layer model.

Secondary batteries for light means of transport - Part 1: Test specifications for performance and durability aspects for lithium-ion and sodium-ion batteries
Scope: This document specifies test procedures for performance and durability aspects of light means of transport (LMT) batteries. These are sealed batteries with a maximum weight of 25 kg that are specifically designed to provide electric power for the traction of wheeled vehicles that can be propelled by an electric motor alone or by a combination of motor and human power, including type-approved vehicles of category L within the meaning of Regulation (EU) No 168/2013 of the European Parliament and of the Council, and that is not an electric vehicle battery. The scope of this document is restricted to lithium-ion and sodium-ion batteries.
LMT batteries contain at least the following general classes:
— batteries of L-category vehicles referred to in Article 2 of Regulation EU 168/2013 of the European Parliament and of the Council (e.g. batteries for light motorcycles, trikes and quads), where the battery weight is less than 25 kg;
— batteries for EPACs (electrically power assisted cycle) with or without type approval;
— batteries for personal mobility devices (PMD), e.g. e-kick-scooters, hoverboards and self-balancing vehicles.
Batteries above 25 kg for mobility are not in the scope of this document, even though they can be used in L category vehicles (e.g. L7 category). Batteries for toys are also not in scope of this document based on the recital 15 of Regulation (EU) 2023/1542: “Batteries used for traction in wheeled vehicles considered to be toys within the meaning of Directive 2009/48/EC of the European Parliament and of the Council, should, for the purposes of this Regulation, not be considered to be LMT batteries, but to be portable batteries.”
Re-used, remanufactured, repaired and repurposed batteries (hereafter called “R-batteries”) are also in the scope of this document.
