Scope

Scope: This document specifies the technical requirements, communication requirements, and test methods for the electric heavy-duty truck battery replacement controller. This document applies to battery replacement vehicles with lifting systems (including dump trucks, tractor trucks, and special-purpose vehicles) and their battery replacement stations, but not to vehicles with chassis-mounted battery replacement systems and their battery replacement stations. Main technical content: The terms and definitions defined in GB/T 19596-2017 and GB/T 29317-2021 apply to this document. 3.1 Frame: A series of data bits that constitute a complete message. 3.2 CAN data frame: A structured sequence of bits necessary for transmitting data according to the CAN protocol, starting with the frame start (SOF) and ending with the frame end (EOF). 3.3 Messages: One or more CAN data frames with the same parameter group number. 3.4 Identifier: The identifying portion of the CAN arbitration field. 3.5 Extended frame: A CAN data frame defined in the CAN bus that uses a 29-bit identifier. 3.6 Priority: A 3-bit field in the identifier that sets the arbitration priority in the transmission process, with the highest priority being level 0 and the lowest priority being level 7. 3.7 Parameter group number (PGN): A 24-bit value used to uniquely identify a parameter group. The PGN includes: reserved bits, data page, PDU format field (8 bits), and group extension field (8 bits). 3.8 Suspect parameter number (SPN): A 19-bit value assigned to each parameter by the application layer through parameter description signals. 3.9 Battery management system (BMS): An important hub for connecting batteries, ensuring battery safety, and providing accurate management and control of battery charging and discharging. 3.10 Service set identifier (SSID): Used to distinguish different networks. Setting different SSIDs allows access to different networks.
