摘　　要：该文对电动客车的电安全设计进行介绍,对电动客车电安全标准进行详细的解读。根据标准(GB 38032-2020)《电动客车安全要求和标准》(GB/T 31498-2015)《电动汽车碰撞后安全要求》,对多款电动客车进行侧面碰撞试验,通过试验后的电安全测量以及数据分析,发现碰撞后客车满足(GB 38032-2020)《电动客车安全要求》,但无主动断电功能,并不能轻易断开电池组与负载端之间的联系,因此存在一定的触电安全。该研究能为电动客车碰撞安全的相关标准的完善和制定提供一定参考。This paper introduces the electric safety design for electric bus,the electrical safety standards for electric bus is explained in detail.According to the(GB 38032-2020)Electric buses safety requirements and GB/T 31498-2015 Post crash safety requirement for electric vehicle,we did a lot of electric bus side impact tests.By the analysis of the electric safety measurement and test data,it is found that the electric bus meet(GB 38032-2020)Elec trie Buses safety RequirementsB\xX there is no automatic power off function,and the system disconnect the connection between batteries and load easily.So there is risk of electric shock.The research provides certain reference for the improvement and formulation of the electric bus impact safety standards.
