[ELI5] What’s happening when a charging battery is full, but still keep receiving power ? (Smartphone stay plugged all night for instance)
In: Technology
When a battery hits full, the charger stops charging. This is built into pretty much all batteries/chargers, either by the nature of how the battery works or by a circuit that exists solely to do disconnect the battery when full.
If this doesn’t happen, then the battery is overcharged and can quickly overheat or even explode.
