GB/T 32896-2016 in English

1. Background of Standard Formulation and Analysis of Technology Evolution

With the rapid development of the electric vehicle industry, the powerhouse is one of the core components, and the standardization of its communication protocol has become the key to ensuring vehicle safety and reliability. This standard is based on the CAN bus communication protocol and combines the needs of the electric vehicle fast battery replacement mode to formulate a unified communication specification.

In terms of technology evolution, this standard absorbs the internationally used CAN protocol framework (such as ISO 11898 series and SAE J1939 series) and optimizes it for electric vehicle application scenarios. For example, a special parameter group (PGN) numbering system is defined at the data link layer and application layer to ensure efficient communication between different nodes.

4. Implementation suggestions

Hardware selection:Select a CAN transceiver chip that meets the communication rate of 250kbps and ensure its electromagnetic compatibility.

Software development:Strictly develop the protocol stack according to the PGN number and message format to ensure that the priority field is correctly configured.

Test verification:Establish a simulation environment to simulate the communication scenario between the power compartment and the vehicle equipment, and verify the message integrity and response time.

Maintenance optimization:Update the firmware regularly to fix potential problems, and adjust the alarm threshold and communication parameters according to the actual operation situation.
