| 摘要: |
| 电动汽车快速发展对充电桩提出了更高的要求。为更好地满足电动汽车充电需求，研究一类可移动式电动汽车充电桩具有重要的意义。通过分析移动式充电桩的环境要求和技术需求，设计了可移动充电桩的硬件结构和软件系统。移动充电桩结构采用了CATIA进行建模，通过有限元软件ANSYS Workbench进行仿真分析验证强度和可行性。充电桩控制系统与车辆BMS及充电模块采用CANBUS总线通信，并由ADUM1412构成CAN隔离电路避免干扰。采用北斗GPS模块ATK-1218-BD构成无线定位系统，系统设计了充电急停安全模块和充电枪的检测模块。研究结果表明，硬件结构最大变形值为3.07 mm，最大应力为134.41 MPa，充电桩重心点的垂线在结构底面范围内，结构符合强度和稳定性要求。控制系统功能完备，安全急停模块和充电枪安全模块保障了充电桩使用的安全，有一定的工程实践参考价值。 |

| Abstract: |
| The rapid development of electric vehicles has posed higher demands for charging piles. It is important to investigate a class of mobile charging piles for electrical vehicles to better satisfy the charging demands. By analyzing the environmental and technical requirements of mobile charging piles, the hardware and software system for a mobile charging pile are designed. CATIA is used to mimic the model of the mobile charging pile structure, while ANSYS Workbench, which is a finite software, is used to simulate and analyze strength and feasibility. The CANBUS bus is applied to establish the communication between the charging pile control system, vehicle BMS and the charging module. A CAN isolation circuit including ADUM1412 is used to avoid interference. ATK-1218-BD, which is a module of Beidou GPS, is employed to constitute the wireless positioning system, followed by a designed emergency charging stop safety module and a charging gun detection module. Results show that the maximum deformation value of the hardware structure is 3.07 mm, while the maximum stress is 134.41MPa. The vertical line of the charging pile gravity center is within the range of the structure bottom. This meets the requirements of strength and stability. The control system has shown complete functions. Specifically, the safety emergency stop module and charging gun safety detection module ensure safety while using the charging pile, providing a useful guideline for future engineering practice.
