    Hello all,

    I have a electric kick scooter and I want to build a "dock station" in my car for it, also I want to read the battery level and transmit it wireless to my smartphone.

    The kick scooter model:
    http://e-twow-us.3dcartstores.com/E-TWOW-Electric-Booster-Scooter_p_12.html

    The battery is LIPO 37.4V – 3.5A.

    The kick scooter has a display on which the level of battery is displayed.

    The question is:

    Do you have any idea how can I read the battery level, then transmit the value to a Arduino and then transmit the value to my pc or smartphone wireless?

    Thank you

    Hi, and welcome to AAC!

    My first thoughts:
    You can use the Arduinos ADC function to read the battery voltage. This value can be sent to your phone with a GSM module, a 433MHz RF module (or equivalent) or I guess you can use an ESP 8266.

    hi,
    can i asked why you needed to transmit it to your smart phone.
    how important to you to monitor this level.since you can read it directly to your scooter without problem.

    nerdegutta: Nice to meet you, thank you for your advice

    JUNELER: My dock station will be mounted in the trunk and I want to know the level of battery when the kick scooter charging and I can not see the screen. For me it is important to know this information.
