Idea: DCC - Discontinuous type charging of the mobile phone battery(An app used for discontinuous charging)

DCC is stands for discontinuous type charging of the mobile phone battery. And used to set the charging time cycle of the smart phone during night time. This way its avoid unnecessary/excess charging of battery(more than 100%) and protecting the battery from overcharging during the night. And same time providing a cell phone with 90-100% charged in the morning to the customer.

Full Description:
See Fig:1
Available options in the android app:
S.No Description Type Range
1 Overnight Mode Boolean output 0 to 1
2 Full Charging done Boolean output 1 to 10
3 Drain Time Analog output 1 to 10
4 1st Cycle Charging Time Analog output 1 to 10
5 Start Button Boolean output 0 to 1
6 Drain Time Analog input 1 to 10
7 1st Cycle Charging Time Analog input 1 to 10
8 LED Boolean input 0 to 1

Usage Procedure of android app:
Plug in the phone charger to the smart phone.
Switch on the Overnight Mode OFF in the android Application.
1. Set the the drain time Eg. 3hrs for draining. During this time period there wont be any charging of the battery.
2. Set the time for 1st cycle charging time. Eg 3hrs. During this cycle battery charging will take place.
Press “start“ button in the application. To start the automatic charging.

Note: After the charging cycle completed, current will pass through “Main Electrical circuit” based on overnight mode option selected or not. If selected it will start the drain and charge cycle again and again until it stopped by unplugging or un-checking the overnight mode.

How the “Main electrical circuit” will work?
Main electrical Circuit is the heart of this total project. And it contains main components which are required to operate the sequence. Main electrical board get the power supply through main plug board. So when the plug board current is on the MEC(Main Electrical Circuit) is on, if main plug board is off MEC also Off.
MEC gets the inputs from android app and start the charging cycle accordingly. Android app given inputs to the MEC are,
1. Overnight mode is on/off(0)
2. Full charging done(1)
3. Drain time(3hrs)
4. 1ST Cycle charging time(3hrs)
5. Start Button pressed(1)
Now with this input the MEB Should charge the smart phone in the following manner.
See Fig:2
Above only one cycle power out given, for many cycles the drain time and 1st cycle charging time to be repeated again and again if the overnight mode option was chosen.
Outputs from MEC:
1. Showing/Sending the remaining time of the Drain time timer
2. Showing/ Sending the remaining time of the 1st Cycle charging time timer
3. And LED Shows the Circuit charging cycle going on or off.
4. Power out signal to smart phone charging.
These outputs (1-4) travel back to the android application and display in the app for better monitoring process.

The combined flow diagram given for both android application and the electrical circuit board:
see Fig:3

1. As a smart phone owner we know how much time will take from “X%” to 100% approximately. By knowing that time and the total time you are away from the phone. You can calculate the draining time. Eg if you are going to sleep at 9pm then wake up at 7 clock in the morning. The by the following method you can calculate the draining time
9-10-11-12-1-2-3-4-5-6-7 =total hours away from the phone 10hrs
To charge the cell phone from “X%” to “100%” is 4hrs (approx) .
Then last 3hrs the phone should be charged to get the phone in 90-100% charged in the morning. So the remaining 3hrs its has to be in draining time.
2. Sender and Receiver can be Bluetooth. By connecting the MEC and phone with Bluetooth the values can be transferred easily between each other.

Problem this idea/invention addresses:
The problem in charging the phone battery overnight and due to that the battery life comes down. To avoiding this problem TWO Technics are proposed one is That by charge termination and followed by cycle charging .
Once a battery is fully charged, the charging current has to be dissipated somehow. The result is the generation of heat and gasses both of which are bad for batteries. The essence of good charging is to be able to detect when the reconstitution of the active chemicals is complete and to stop the charging process before any damage is done while at all times maintaining the cell temperature within its safe limits. Detecting this cut off point and terminating the charge is critical in preserving battery life. In the simplest of chargers this is when a predetermined upper voltage limit, often called the termination voltage has been reached. This is particularly important with fast chargers where the danger of overcharging is greater.

Charge termination is one part, after that the battery can't be kept as its because the charging will go down with respect to time so we have to charge it again after particular period post ot charge termination. Here comes the cycle charging.
