Week 8 (Oct. 17, 2018): Induction Charging, Battery, and Motor Concerns

Today, while our meeting was brief due to the ME 195A seminar for Writing Assignment #2, we discussed the options we have for the motor, battery, and charging. If we decide to use last semester’s 7.4 LiPo battery, we must find a micro-LiPo charger, hopefully rated at around 2 Amps, that will step-up or step-down the voltage to 7.4 V. The stepping-up or stepping-down will depend on which induction charger receiver module we will use:
a.       Input voltage: DC5V
b.      Input current: 1.2-2A
c.       Charging voltage: 5V
d.      Charging current: 500-1000mA
e.       Transmit power: 5W


  1. Small Scale Controls Team,

    I am commenting both for this blog post, and the previous blog post.

    It seems your team has mostly done research for the past 10 - 11 weeks which is far too much. Please discuss with Dr. Furman and Ron on purchasing your wireless charger and module and motor encoder....

    I want to start seeing some results of your research efforts, because as of now, I am concerned by the lack of engineering design and analysis your team has done so far.

    How will you integrate your inductive charging system to the guideway and bogie? What are your plans for this?

    How will your controls system translate its tracking information? Does this go to a user interface (HUD)? How will you send user data to the bogie system to allow it to complete a loop or go to a charging station?

    Please begin by making a block diagram indicating the flow of information from your program (i.e., system powered on, HUD (on computer) turns on, bogie battery turned on, battery on board voltage / current detector on, if battery is less than 4 volts (arbitrary) then send bogie to charging station, if battery full wait for command, send command from user interface, follow instructions set by user, so on and so forth...)

    In addition, start developing a wiring diagram for your circuit board / bread board. There are many free online programs that can help you with this.

    It is time to start seeing some results! Code, wiring, hardware, etc.
