How does a battery charger circuit work?
Inductive battery chargers use electromagnetic induction to charge batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery.
Can you use a power supply as a battery charger?
A power supply used as a charger cannot do this, and will continue to pump energy into a battery regardless of its condition; fully charged, battery fault, or shorted cells. In order to achieve maximum battery service life, a properly designed charger should always be used to charge cells.
How can I charge 12V battery?
How Exactly Do You Charge a 12-Volt Battery? Connect your 12-volt battery to the battery charger by attaching the BLACK negative cable from your charger to the negative terminal of the 12-volt battery. Make sure to use the clips or clamps to connect to the terminal securely.
What is the voltage of a battery charger circuit?
The battery charger circuit can work with a wide range of input DC supply voltages. The circuit can operate in the range of voltages approximately above 6.2V and up to a maximum 18V (Maximum operating voltage of IC7555). Normally a 555 IC has a threshold and trigger voltage of 2/3 and 1/3 of the supply voltages respectively.
How do I know if the battery is charging?
The green LED should instant become ON indicating the battery is being charged. You can attach a voltmeter across the battery to monitor its charging, and check whether the circuit cuts off the supply correctly or not at the specified limit.
What do the LED lights on the battery charger mean?
The red light (D2 LED) indicates the battery is charging and the green light (D1 LED) indicates that the battery has fully charged. The battery charger circuit can work with a wide range of input DC supply voltages.
How does a 6V automatic battery charger work?
Here the circuit for a 6V automatic battery charger circuit with overcharge protection, LED charging indicator and current limiting feature. The circuit controls the charging of the battery by taking feedback of the voltage across the battery terminals.
