Problems solved by technology

[0003] In modern cars, the equipment based on mains electricity should be applied in the car. Usually, it can only be completed by adding an on-board inverter to the cigarette lighter. Only a few luxury vehicles have a simple built-in correction wave inverter. Inverter, and the built-in inverter in this luxury car is only installed on the car. It is impossible to know the current working status and load condition of the on-board inverter through the vehicle's central control system, and the car cannot pass the current Intelligently change and adjust the running state of the inverter according to the operating conditions of the inverter. In this case, the inverter cannot exchange data with the central control system. If the inverter is still working, it may cause hidden dangers to the safety of the drivers and passengers in the car due to the high voltage output

Abstract

The invention relates to an electric car intelligent inverter based on a CAN bus. The electric car intelligent inverter comprises an intelligent inverter control unit, a CAN communication module and a DC / DC module. The CAN communication module is connected with the intelligent inverter control unit, and the CAN communication and the intelligent inverter control unit transmit signals to each other. The intelligent inverter control unit is connected with the DC / DC module, and the intelligent inverter control unit and the DC / DC module transmit signals to each other. The CAN communication module is connected with a CAN bus interface. According to the electric car intelligent inverter, data interaction between the intelligent inverter and a center control display LCD in a car cab can be achieved by means of the CAN communication module, and a driver and passengers can know working conditions of the inverter in time.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an intelligent inverter for electric vehicles based on a CAN bus. Background technique [0002] In recent years, the development of new energy electric vehicles has been very rapid. Electric vehicles have integrated a large number of electronic control systems and equipment, such as battery management systems, motor control systems, and on-board electronic equipment. CAN bus is a communication protocol developed by German Bosch Company to solve the data exchange between numerous controllers and sensors in automobiles. Due to the outstanding reliability, practicability and flexibility of CAN bus, it has been widely used in the industry. Recognized, and has officially become an international standard and industry standard, and has been widely used in automobiles. [0003] In modern cars, the equipment based on mains electricity should be applied in the car. Usually, it can on...
