    Once the battery is full, the charging circuit stops drawing power from the charger until such a point where it decids to resume charging. Assuming a properly functioning charging circuit you cant add excess energy to the battery. There is no redirrcting of energy, the chaarging circuit just stops drawing power from the charger.

    What happens when a battery reaches 100 volts?

    As soon as the battery hits 100% mark, the internal circuit disconnects the power source from sending any other current. The power circuit is designed to detect the upper limit and will cut off the power connection when it reaches the limit. So as soon as the battery is ultimately charged, it stops receiving charging energy.
