Charging batteries and how voltage affects it

I know that when I am charging a battery, we need higher voltage than the battery is rated at in order to "push" current into the battery itself. Right? OK. Since that is true, is it possible for me to use a lower voltage, but into the separate battery packs? I WILL EXPLAIN. I am sending current into a 10 volt light bulb.

voltage

$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

C/20 = C/20 or 20 Hr AH rating of the battery bank. C = charger current. Charge current value is the peak charging Amp output to the battery bank in the Bulk charge. If the charge source generates more current than the charge controller is capable of outputting, the max charge output of the controller is used.

800V Charging vs 400V: Comparing EV Architectures

Although compatible with 800V EV charging stations, they will be limited to 400 Vdc output, which could result in slower-than-expected charging speeds depending on the charger''s output current. 800V Battery Architecture. In the same way as 400-volt architecture, 800-volt architecture has a voltage range rather than a fixed battery voltage.

Battery Chargers and Charging Explained

The battery saturates when it reaches the voltage limit; the current reduces until the battery could no longer receive any more charge, and the fast charge is halted. The low-current threshold varies with each battery. Nickel-based batteries are designed to charge with a constant current and with no restrictions on voltage increase.

Generally: You usually don''t charge batteries just by connecting them to an uncontrolled voltage source. The correct method for charging a battery depends fully on its type, its current charge status and usage scenario.

Battery Charging Stages & Battery Charging Procedure

Batteries have four main charging stages: pre-charging, constant current, constant voltage, and topping off. Pre-charging is the stage where the battery charger supplies a low current to the battery to help reduce sulfation. Constant current is the stage where the charger supplies a constant amount of current to charge the battery.
