In our day life we need to use a lot of batteries almost for everything, this batteries are in our devices of daily use. But the lifetime of this batteries is not as long as we want, so we constantly need to buy new ones. And this is expensive and environmentally harmful. We can also use rechargeable batteries, but this one’s requires a lot of difficult charging actions. But what if we are capable to recharge this batteries? This is the aim of our project. Create a device in order to recharge this batteries and give them a second life. And how we are going to do this? We have created a box, with an internal mechanism that is capable to recharge this batteries in less than 100 minutes.

Main problem:

•Youneed to control the charge time

• You must manually change the batteries in the charging station, for charging several ones

• You ought to identify the battery is charged or not

•Memory effect reduces the maximum capacity from the battery,which is not fully charged

•To identify batteries that have expired

Our solution:

Thissmart charging station that allows you to not think about charging time and the battery charge level. Moreover you can charge a plurality of batteries simultaneously.

Step 1: How It Works

Picture of How It Works

Step 2: What You Need

Picture of What You Need

1) Servo 5 pcs

2) Real time clock module

3) Voltage sensor

4) Set of wires mile-mile 65pcs

5) Connecting wires male-female 40 pcs

6) Plywood

7) Arduino

8) Bread board

9) Laser module

Step 3: Design

Picture of Design

Our device is a box elongated in length, the entire upper part is made from a single panel

There are our logo on the front side, instructions on the top shelf, the device name on the side panel.

Step 4: Modeling and Assembly

Picture of Modeling and Assembly

We attached files- designed in the CAD-program (Solid Works) details of the model.

You should cut out all the parts of plywood with laser and gather together like in 3D model.

Step 5: Electronics

What you should do is to detect the type of battery (NiCd, NiMh, or plain) and make a charge cycle, resp. eject the plain batteries as they should not be charged (I read about a way to even recharge them using asymmetric voltage, but have never tested that). Else this is a very cool project!

this is awesomw!

Very clever robot you got. I like the good/bad filter.

If you wanted to get really complex, have the lower charger with reverse polarity for batteries put in backwards.
