T/TSAQ 10003-2024 Electric heavy-duty truck charging station and vehicle charging technology specification Part 1: General principles

Scope

Scope: This document specifies the basic functions and replacement steps of electric heavy-duty truck battery swapping stations and vehicles. This document applies to vehicles with on-board battery swapping systems (including dump trucks, tractor trucks, and special-purpose vehicles) and their battery swapping stations, but does not apply to vehicles with chassis-mounted battery swapping systems and their battery swapping stations. Main technical content: 3.1 Battery Swapping Station A facility that provides battery replacement services for electric vehicles. Note: Also known as a battery swapping station. 3.2 On-Board Swapping System A system composed of various components mounted on a battery swapping vehicle to perform battery swapping operations, including the battery swapping system, battery swapping base, battery swapping connectors, and battery swapping vehicle controllers. 3.3 Battery Swapping System A system composed of mechanical and electrical equipment for replacing the power battery of electric vehicles. 3.4 Battery Swapping Base A mechanical device installed on the frame of a battery swapping vehicle to support and install the battery box, typically consisting of a battery swapping base frame, battery box locking mechanisms, battery swapping mechanisms, battery swapping connectors, and other mechanical and electrical accessories. 3.5 Locking Structure A mechanism installed on the battery swapping base used to fix the battery swapping system in place. 3.6 Guiding Mechanism A mechanism installed on the battery swapping base, typically including coarse and fine guidance. It is used to perform coarse and fine positioning during the installation of the battery swapping system on the battery swapping base, ensuring the correct and rapid cooperation between the battery swapping system and the battery swapping base. 3.7 Swappable Electrical Connector A dedicated connector used for conductive connection between the battery swapp
