Overcharge occurs when charging current is forced through after the battery reaches its upper voltage or state of charge (SOC) limits , usually due to malfunction of battery charger or inaccurate detection/estimation of battery states (such as SOC) in battery management system (BMS) .
If it is too high then it will overcharge the battery, but you might be able to add a voltage regulator to lower the voltage and limit the current to suit your battery. I'm assuming you're referring to lead acid chemistry. If the voltage (potential) is not greater then no current will flow, therefore it is impossible to overcharge.
In the standards or regulations, the overcharge performance of single lithium-ion battery is evaluated through several overcharge tests, during which a controlled current is applied to the tested battery (e.g. 1/3 C) up to a set of charge limits (e.g. 2.0 SOC, 1.5 times the upper cut-off voltage).
If the battery can take it then the power supply may not (either overheating, shutting down or blowing a fuse). A simple way to fix this is wire a 6V or 12V incandescent light bulb in series with the battery. The light bulb will limit current and also glow weakly to show that the battery is charging.
If your power supply voltage is too low then it just won't work. If it is too high then it will overcharge the battery, but you might be able to add a voltage regulator to lower the voltage and limit the current to suit your battery. I'm assuming you're referring to lead acid chemistry.
The effects of charging current, restraining plate and heat dissipation condition on the overcharge performance of a 40 Ah lithium-ion battery are evaluated. The batteries overcharge behaviors show only minor changes with the increase of charging current, as the TTR remains at around 113 °C and the SOC TR decreases slightly.
