How do you charge a battery?
Charging batteries is simple (in theory) – put a voltage across the terminals and the battery charges. If safe charging, fast charging and/or maximum battery life are important, that’s when things get complicated.
How does a battery charging circuit work?
The charging circuit regulates the current supplied to the battery by controlling the voltage across a resistor or other current-sensing element. The current sensor measures the current flowing to the battery, and the charging circuit adjusts the voltage to maintain the desired current level.
What is a constant voltage charging circuit?
Constant voltage charging circuits are the most common type of charging circuit. They maintain a constant voltage until the battery is fully charged, after which the current drops off. The voltage is typically set to the battery’s maximum voltage, and the current is reduced as the battery becomes fully charged.
