Design of CAN bus communication module in lithium battery management system based on MKE06Z64 chip

在搭载CAN总线的电池管理系统中,电池管理系统通过CAN总线完成对电池的电压、电流、温度等信息的采集,以此来实现对电池的保护。通过介绍以MKE06Z64为主控芯片,以ML5238作为电池采集芯片的电池管理系统,对其中的CAN总线通信模块进行设计,包括CAN控制器、CAN收发器以及光耦隔离模块,介绍了CAN总线模块的软件设计和硬件设计,同时以PC上位机进行测试,测试结果表明所设计的CAN总线通信模块在以MKE06Z64为主控芯片的电池管理系统中具有可靠性好、通信性能稳定等特点。

In the battery management system equipped with CAN bus, the battery management system completes the collection of battery voltage, current, temperature and other information through the CAN bus, in order to achieve the protection of batteries. Through the introduction of MKE06Z64 as the main chip, ML5238 was adopted as a battery management system for battery acquisition chip, to design the CAN bus communication module, including CAN controller, CAN transceiver and optical isolation module, and the software design and hardware design of CAN bus module were introduced. The designed lithium battery management system with MKE06Z64 as the main chip was tested with the PC test. The test results show that the CAN bus communication module has the characteristics of good reliability and stable communication performance in the battery management system.
