DJI TB55 Battery Communication

$750-1500 USD

Completed
Posted over 5 years ago

$750-1500 USD

Paid on delivery
Instructions detailing necessary hardware and communications methods to turn on the battery, read cycle count, cell voltage for each cell, temperature, warning flags or error codes, percent charge and battery firmware version for the DJI TB55 battery. While the battery is on and these data are being read, charging and discharging the battery must be allowed at the same time. All this functionality must be capable in a device other than the drone for which these batteries are designed (ie I want to use these batteries in another device for both charging and discharging other than the drone or chargers designed by DJI). My device will use either the Raspberry Pi 3 b+ or the Arduino ESP32 microprocessor so communication must match / be capable by these two devices. Quote must include all time and materials entirely. (If you need to buy batteries, figure that into your bid) Milestone payments can be discussed before awarding the quote. Let me know your expectations and needs before I award the project.

Hi, This is Özge. I and My husband are electronics engineer. My husband's Master Thesis' subject is Smart Batteries. He is already doing this project. He has designed a curcuit and software then he can read the cycle count, cell voltage, temperature etc. We already have this system. For your project, we need to change just battery. This is not an easy project. My husband has been working on this project almost one year. So a freelancer who didn't make this project before doesn't able to deliver in a month etc. We already have the answers. Please contact with me and let us answer your questions. Have a nice day!

Hello I recently finished a job with a DJI drone - where the arduino was supposed to receive commands from the flight control and deliver keypresses to a pc . I can deal with your task. The materials i need are _ arduino and probably a timer crystal. the communication will take place over SMBUS an i2c like protocol, so no extra hardware is needed. However, arduino is known to cause problems with ceratin smbus implementations on certain firmware. so we might have to use AVR. AVR itself costs relatively low - about 2-5 USD each. So I can not give you an exact quote without speakign to you first, but roughtly : 1. AVR : 20 usd 2. crystal : 4 usd 3. other things : 15 usd 4. AVR programmer (i have one) : 0 5. postage : 10 usd ----------------------- total 50 usd + the dji battery. Thank you - looking forward to see you in chat. price is 600 usd.
