基于Silver的BMS测试平台搭建方法

The BMS Test Platform Building Method Based on Silver

主要研究如何将BMS的ASW应用层软件进行编译,生成VEcu(虚拟控制器),然后在Silver平台上对PlantMode和VEcu进行集成,对BMS软件的ASW进行功能验证。在SIL环境中需要建立完整的车辆动力学和SoftEcu模型,可以和VEcu形成闭环控制。当请求上高压的命令发出后,BMS需要响应该指令,BMS能够控制主负、预充和主正继电器进行闭合;当SOC过低时,发动机模型可以对BMS进行冲电;当行车过程时,BMS可以进行放电;在充放电过程中BMS可根据电流的大小,进行SOC的实时修正。通过搭建该测试平台,可以在BMS硬件和底层没有准备好的前提下,对BMS软件逻辑进行全面验证,加快项目的开发进度。

This paper mainly studies how to compile BMS ASW application layer software to generate VEcu(virtual controller),and then integrate PlantMode and VEcu on Silver platform to verify the ASW function of BMS software.Complete vehicle dynamics and SoftEcu models need to be built in the SIL environment,allowing closed loop control with the VEcu.When the request for high voltage command is issued,BMS needs to respond to the command,BMS can control the main negative,precharge and main positive relay to close;When SOC is too low,the BMS can be flushed by the engine model.When driving process,BMS can discharge;BMS should make real-time correction of SOC according to current during charging and discharging.By building this test platform,the BMS software logic can be fully verified under the premise that the BMS hardware and the underlying layer are not ready,and the development progress of the project can be accelerated.
