Scope

Scope: This document specifies the safety requirements and test methods for lithium-ion batteries and chargers used in electric bicycles. This document applies to the production and sales of lithium-ion battery packs (hereinafter referred to as "battery packs") and matching chargers for electric bicycles; Main technical content: It consists of four parts: battery packs, chargers, charging interfaces, and communication protocols. a) The technical content of the battery packs and chargers is organized in the order of environmental adaptability, electrical performance requirements, management systems (BMS), safety requirements, and shell requirements. The technical indicators in this part are largely derived from the mandatory national standards "Draft for Review" of GB/T 36972-2018 "Lithium-ion Batteries for Electric Bicycles" and "Technical Requirements for Electric Bicycle Chargers". The changes include: - According to the requirement of consistent content order, the sections of the referenced standards have been adjusted; - Most of the protection capacity requirements in the lithium battery national standard 5.4.2 have been replaced by the content in QB/T 5513-2021 "Management System (BMS) for Lithium-ion Battery Packs for Electric Bicycles", increasing the protection content from six indicators to 12, doubling the number. More importantly, it introduces that the BMS is a necessary condition for establishing communication protocols; - The technical requirements for chargers have added intelligent charging management requirements. b) The interface between the battery pack and the charger is listed separately in a chapter, and additional communication interface requirements have been added to the interface. c) The purpose of the communication protocol is: "The battery pack and charger should have the ability to communicate with each other, transfer charging parameters and the status of the battery pack and charger, ensure that the battery pack and charger only charge
