WEEK EIGHTEEN

APPLICATION AND IMPLICATION

 

What will it do?

My final project is a machine that can measure the remaining energy of batteries and automaticly distinguish the used ones and new ones.


Who has done that beforehand?

Nanfu Batteries has made a testpad to test the remianing energy of the battery. However, it is operated manually; it is not accurate; and it cannot test massive amount of batteries at the same time.


Material and components

Here are some possible materials and components:

Power supply: 5V USB powerjack

Resistors : 10k 499R

Capacitors: 1uf

Microcontroller: ATtiny 44

Board: Mill by myself

One DC motor

One servo motor

Frame: density board cut by laser cutter

Attaching components: made by 3D printer


Where will they come from?

Being bought online; from the storage of my lab, and cut / 3D printed by myself.


What parts and systems will be made?

System: using arduino IDE for programming. Also using LED to represent the information of the battery.

What processes will be used?

Electronic production, electronic design, output devices, input device, 2D/ 3D design, laser cutting, 3D printing, vinylcutting, embedded programming, mechanical design.

What tasks need to be completed?

Make the structure of the machine; design, mill and stuff the circuit; program the system, use some batteries for testing.

What other questions need to be answered?

How to make the machine compatible with #5 and #7 batteries at the same time?

What is the schedule?

From June 12nd to June 17th.

How will it be evaluated?

By measuring the successful rate of correctly classifying the batteries in low or high power.
