Hi all, I am wondering if there is a need for impedance matching to charge a battery from the source? Thank you

Thank you Nsaspook :)nsaspook said:No need for impedance matching of the transmission line type but the charging source impedance/resistance usually should be relatively in range of battery internal charging resistance to deliver the maximum recommended current at the needed difference in charging voltage from the flat battery voltage when fully discharged. This is usually handled by 'circuit' using a current source set to max charge current with a voltage limit set to max charging voltage. This 'circuit' doesn't have to be strictly electronic, a properly designed 'battery charging' transformer and rectifier can have the same effect.
Impedance matching for battery charging is the process of ensuring that the electrical impedance of a battery and the charging circuit are closely matched. This allows for efficient transfer of energy between the battery and the charging source.
Impedance matching is important for battery charging because it maximizes the amount of energy transferred from the charging source to the battery. This ensures that the battery is charged quickly and efficiently, without wasting energy or causing damage to the battery.
Impedance matching can significantly impact the charging time of a battery. When the impedance of the battery and charging circuit are closely matched, the charging process is more efficient and takes less time. However, if there is a mismatch in impedance, the charging time can be significantly longer.
If there is a mismatch in impedance during battery charging, it can lead to inefficient charging, longer charging times, and potential damage to the battery. This is because a mismatch in impedance causes energy to be wasted and can also create excessive heat, which can be harmful to the battery.
Impedance matching can be achieved by using a charging circuit that is designed specifically for the battery being charged. This can involve using a matching transformer, adjusting the charging voltage, or using specialized charging algorithms. It is important to consult the battery manufacturer's recommendations for optimal impedance matching during charging.
