Embodiment Construction

[0019] like figure 1 As shown, the microprocessor unit MCU is the control core of the monitoring system of the entire electric vehicle regenerative braking and energy system comprehensive experiment equipment. During initialization, when the corresponding button is selected on the touch screen, the touch screen will send the detected position signal to the microcomputer. The processor unit MCU, the microprocessor unit MCU judges the button selected by the user according to the position signal and sends the corresponding display control command to the touch screen through the RS232 serial port; The form is transmitted to the AD port of the microprocessor unit MCU, and the microprocessor unit MCU reads the value of the AD port and converts it to obtain the values ​​of speed, torque, voltage, current and temperature, and transmits these values ​​to the touch display Display; when the collected voltage, current, and temperature signals exceed the normal range, the sound and light ...

Description

technical field [0001] The invention relates to a monitoring system for an electric vehicle regenerative braking and energy system comprehensive experiment device. Specifically, it involves detecting various parameters of the operation of the electric vehicle regenerative braking and energy system comprehensive experimental device, and analyzing and calculating the detected data, and then performing an electric vehicle regenerative braking and energy system comprehensive experiment according to the analysis results. The device is controlled. Background technique [0002] With the increasingly serious problem of traditional vehicle exhaust emissions and the shortage of oil resources, the trend of electric vehicles replacing traditional fuel vehicles has become more and more obvious. One of the major factors restricting the development of electric vehicles is the battery. However, electric vehicles powered by traditional batteries are constrained by factors such as low batter...
