Dynamo Car Battery Charger

This video is about charging rechargeable batteries with cycle dynamo.

Dynamo car battery charger. This project demonstrates charging two 1 2v rechargeable batteries with 12v cycle dynamo using a 12v solar charger circuit. The charger setting could also influence how long it takes to charge the battery. Be aware that there is a limit to size of charger you can use on your batteries. But dynamo is giving current.

The length it takes to charge a car battery with a 12 volt charger depends on the capacity of the battery as well as the charger s features such as if it s micro processor controlled and designed to enhance agm charging characteristics. Half of the plates are connected to each terminal. If the power came from an ordinary battery it would soon run down so a car has a rechargeable battery and a charging system to keep it topped up. A car uses quite a lot of electricity to work the ignition and other electrical equipment.

A basic home battery charger incorporates a transformer and rectifier to change the mains 110 220 volt alternating current to 12 volt direct current and allows the mains supply to provide a charging current at a rate determined by the state of the battery. Fortunately you can also use a gas generator to recharge a battery if you also have access to a battery. The battery has pairs of lead plates immersed in a mixture of sulphuric acid and distilled water. The dynamo will charge the battery as long as its voltage is higher than the battery s voltage.

But what i don t understand is how can a battery be utilised and charged at the same time. Whether cold weather from a blizzard has caused a car battery to run down or the battery has died in an isolated location batteries sometimes need charging when ac power from a home or garage is not available.

You are correct as your battery approaches a full charge it will be around 14 volts and the dynamo is rated at 12 volts so it will not be charging in this situation if it is actually 12 volts. That is head lights drawing current. In the case of a battery in good condition the rate of charge may be around 3 to 6 amps with a normal home charger.
