Electron flow in a battery
The animations below demonstrate how electrons move around within a battery when it is connected in a circuit. Pay attention to the direction of the electrons in the different cycles, charge and discharge.
Note when the battery is not connected, there is no electron flow.
Our custom made battery charger circuit
Our custom made battery charger circuit
This is a 3d CAD (computer aided design) model of the actual battery chargers circuit which Mr Berry has built for you. Its consists of the following components (parts):
TP4056 USB charging module circuit.
DC 3 volt to 5 volt, 1 amp voltage regulator.
A 3 pole toggle switch to switch between charging battery and drawing from battery.
A 18650 (form factor) 3.7 volt rechargeable battery.
A diode to prevent a backwards current from the battery returning to the charging circuit (when the battery is charged) and damaging it. A diode acts as a one-way valve for electrical current.
We will be using this circuit to see if we can successfully charge a battery (so that we can run our own phones or tablets off of it), using a selection of different renewable sources, wind, solar, etc. We will see which is the most reliable for us.
