Scope

Scope: This document specifies the requirements and test methods for electric bicycle battery exchange cabinets and their accompanying lithium-ion batteries. This document applies to equipment used for centralized charging and battery exchange of lithium-ion battery systems (referred to as "lithium battery systems") for 48 V rated electric bicycles. Main technical content: The revised "Technical Requirements for Electric Bicycle Battery Exchange Cabinets" group standard consists of 5 chapters and 27 sections, replacing T/BIKE 7-2020. The basis for this revision is the national standard GB/T 4223.6-2022 "Centralized Charging Facilities for Electric Bicycles - Part 1: Technical Specifications", which does not include lithium-ion batteries, an important component of battery exchange cabinets. Therefore, this revision still follows the content of the 2020 version, including three parts: cabinet, lithium-ion battery pack, and communication protocol. At the same time, it extensively references national standards and significantly reduces the length of the document, so it has been merged and renamed as "Technical Requirements and Test Methods for Electric Bicycle Battery Exchange Cabinets". This standard requires battery exchange cabinets to comply with section 4.3 of Chapter 4 of GB/T 42236.1-2022 "Centralized Charging Facilities for Electric Bicycles - Part 1: Technical Specifications", and lithium-ion battery systems to comply with GB 43854-2024 "Safety Technical Specifications for Lithium-ion Batteries for Electric Bicycles". The differences are described as follows: (1) The requirements for battery exchange cabinets compared with section 4.3 of Chapter 4 of GB/T 42236.1-2022 have been adjusted as follows: (a) The recommended indicators for the dimensions of hard-wired charging cabinets have been raised to compliance indicators; (b) The lithium-ion battery system's low-capacity deactivation function has been added; (c) The communication protocol specif
