新型纯电动汽车车载充电器的设计

Design of New All-Electric Vehicle Car Charger

电动汽车电池充电不方便以及充电效果的不理想是制约电动汽车发展的重要原因。提出了一种新型纯电动汽车车载充电器的设计方案,采用直流电机绕组线圈作为升压电路的储能电感,逆变桥电路作为开关电源的功率开关管,实现对电流和电压的调节,通过整车控制器中的充电控制程序实现对该充电过程的控制。该方案充分利用电动汽车的现有资源,只需在原有电动汽车控制器中加入少量元件即可实现整个充电过程,简化了充电的结构。针对这一方案,进行了系统可行性分析和系统硬件的设计,最终通过实验进行了验证。

The important reasons of restricting the development of electric vehicles are that the electric chargingis not convenient and charging effect is not proposed. DC motor winding bridge is used as the power What＇ s more, the control of c coil is used as ideal. A new design scheme of all-electric vehicle car charger is the energy storage inductors of booster circuit, and the inverter switch tube of switch power supply circuit to regulate harging process is achieved by charging control program the current and voltage. of the vehicle controller. This scheme makes full use of existing resources of electric cars. Whole charging process can be realized by adding a few components in the original electric vehicle controller, and the structure of charging is simplified. The feasibility of the system is analyzed and the design of hardware is completed.
