摘　　要：随着人们对资源的消耗以及由此带来的环境污染,而引发社会的广泛关注,新能源汽车技术发展也由此受到青睐。在新能源汽车中,电动车电池性能及电量的准确测量与显示是电池技术的重要一部分。本系统以STM32微处理器为核心控制器,设计了USB-CAN转换器,可实现电池电量的实时测量与显示。该系统置于电动汽车电子系统中,可将电池电量等状态信息放至CAN总线上,再通过CAN-USB转换器传入PC上位机,将数据通过人机交互界面显示出来,实现数据信息的交互。With the consumption of resources and the resulting pollution, caused widespread concern in society, the development of new energy automotive technology has thus favored. In the new energy vehicles, electric vehicle batteries and power performance measurement and accurate display is the important part of the battery technology. This system has taken the STM32 microprocessor as the core controller, and designed the USB-CAN converter, enabling real-time measurement and display battery charge. It has been arranged in the electric vehicle electronic system, the battery charge state information can be put to the CAN bus, and then through the CAN-USB converter incoming PC host computer, the data is displayed through man-machine interface, and it realizes the data information interaction.
