Read the battery level of the car

1. Experimental purpose

Realize the reading of the battery level of the car.

2. Experimental path source code

Enter the car system, end the car program, enter "ip (ip is the car's ip): 8888" in the browser, enter the password "yahboom" Then log in Enter the path of Rider-pi_class/2.Basic Control Ooperations/8.Read the battery level of the car and run Read battery.ipynb.

3. Experimental phenomenon

After running the code, print out the battery power data

4. Main source code analysis

while True:
vol = g_car.rider_read_battery()
print("vol:"+str(vol)+"%")

Read the battery power data through the API interface. And print it out.
