Automatic car Battery Charger
The majority of dirt cheap ordinary chargers don’t include any regulation circuitry and so will over-charge a vehicle battery if you’re unwise enough to leave it permanently connected. Our proposed project is to build a charger that can act as both a standard charger, and a float charger that you can leave permanently connected without the slightest risk to your battery or fear of over-charging. What’s more, it doesn’t use any ‘exotic’ components and is ridiculously cheap.
