Schematic diagram:
Note: due to the requirements of sampling accuracy, 1% high-precision resistors are required for sampling related resistors R5, R7, R8, R9 and R15 ；
Basic function description:
Three level display, which can support the display of input voltage, output voltage and charging current; Switch the display data once every 3 seconds ；
The display range of vehicle charging input voltage is 5v~40v, the display error is within ± 0.2V when the input voltage is 5v~24v, and the display error is within ± 0.3V when the input voltage is 24v~40v ；
The display range of vehicle charging output voltage is 5v~40v. The current scheme is to output power of 5V and supply power to MCU at the same time; Other fast charging schemes have output voltages of 9V and 12V, which need to be powered to MCU after 5V voltage stabilization; The display error of output voltage is within ± 0.2V;
Basic function description:
The display error of output current is within ± 0.2A; At present, there are two current display methods, one is with the unit "a", but the result retains 1 decimal place, and the other is that the result retains 2 decimal places;
The number of USB charging ports can be expanded ；
Extended function description:
Overvoltage prompt function; When the standard voltage is 12V and the input voltage exceeds the standard voltage ± 2V, there will be a flashing prompt; When the standard voltage is 24V and the input voltage exceeds the standard voltage ± 4V, there will be a flashing prompt ；
Breathing lamp function, with breathing lamp prompt when charging ；
Temperature real-time display function requires hardware to add thermistor ；
Nixie tube description:
The nixie tube is a 6-pin three digit common cathode nixie tube with decimal point, and the size is 0.25 inch
