The invention discloses a range extender controller for an electric automobile. The range extender controller comprises a signal input interface, a preheating module, a CPLD chip, a CAN communicationmodule and a power supply; the signal input interface and the preheating module are electrically connected with the CPLD chip; the CPLD chip is electrically connected with the CAN communication module; the CAN communication module is connected with a range extender and a vehicle control unit through a CAN bus; the power supply supplies power to the signal input interface, the preheating module, the CPLD chip and the CAN communication module. The controller is independent of a whole vehicle control system; the CPLD chip is used as a main control device; a peripheral hardware circuit module is set up; the CAN communication module communicates with the vehicle control unit; and therefore, the control and preheating management of the range extender are achieved. The controller is high in control precision, safe and reliable, and reduces the data processing amount of a vehicle control system of an extended-range electric vehicle to a great extent.
本发明公开了一种电动汽车增程器控制器,包括信号输入接口、预热模块、CPLD芯片、CAN通信模块和供电电源,所述信号输入接口和所述预热模块均与所述CPLD芯片电连接,所述CPLD芯片与所述CAN通信模块电连接,所述CAN通信模块通过CAN总线分别与增程器和整车控制器连接,所述供电电源为所述信号输入接口、预热模块、CPLD芯片和CAN通信模块供电。该控制器独立于整车控制系统外,采用CPLD芯片作为主控器件,通过搭建外围硬件电路模块,并通过CAN通信模块与整车控制器通信,实现对增程器的控制和预热管理,该控制器不仅控制精度高,且安全可靠,极大程度上降低了增程式电动汽车的整车控制系统的数据处理量。
