Is a battery voltage drop real?
So, the voltage drop is real — the measured voltage is what your load gets. The more current it draws from the battery, the lower is voltage it gets. When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load.
What happens if a battery is not in equilibrium?
Since a battery under load is not in equilibrium, the measured voltage and battery capacity may differ significantly from the equilibrium values, and the further from equilibrium (ie the high the charge or discharge currents), the larger the deviation between the battery voltage and capacity equilibrium and the realistic battery voltage may be.
What happens if a battery is over voltage?
The overvoltage causes a deviation of the voltage and capacity from the equilibrium values calculated earlier. As shown below, during discharging, the battery voltage is lower than that in equilibrium, while during charging, a higher voltage than the Nernst voltage is required.
What is a good charge current for a battery?
This means that the current should be no more than half the rated capacity of the battery. So for example, if you are using a 54 Ah battery, the charge current should be no more than 14A. Using too high a current can cause damage to the cells and reduce the life of the battery
What happens if a battery is connected in series?
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
What happens when a battery voltage is maintained at 4.2V?
Basically, A battery voltage is maintained at 4.2V, the charging current gradually decreases, and the charging speed becomes slower. This stage is mainly to ensure that the battery is fully charged.The battery is fully charged when the charging current is lower than 0.1C or 0.05C.
Battery voltage and capacity in non-equilibrium
