Scope

Scope: This document specifies the basic requirements, functional requirements, climate environmental conditions, power supply requirements, environmental adaptability requirements, internal temperature rise requirements, safety requirements, charging output requirements, mechanical strength and mechanical vibration requirements, product marking, packaging, and transportation requirements for portable conductive fast chargers for electric bicycles. This document is applicable to portable conductive fast chargers for electric bicycles. Main technical content: Based on the current application status of electric two-wheeled lithium battery bicycles and the characteristics of conductive on-board battery charging equipment, the requirements for its design modules, functional modules, adaptability, and safety are highlighted. (1) For the new generation of efficient fast-charging conductive on-board battery charging equipment designed for electric two-wheeled lithium battery bicycle charging, it features simple operation, complete functionality, and applicability to charging various electric two-wheeled lithium battery bicycles. (2) Intelligent charging, where the charging process is controlled by the electric two-wheeled lithium battery bicycle BMS sending charging requests to the charger via communication functions, thereby controlling the output parameters of the charger to ensure the safety of the entire charging process. During the charging process, the charger and the electric two-wheeled lithium battery bicycle BMS exchange information on charging parameters in real time. (3) Fast charging, where the intelligent fast-charging battery can achieve a maximum charging current of 15A or more, capable of charging an electric two-wheeled lithium battery bicycle battery management system from 20% to full in one hour.
