Constant current is an algorithm for charging lithium-ion (Li-ion) batteries — specifically those used in EVs. As its name suggests, constant charging leverages a constant current. When charging an EV with constant current, the EV will receive the same current the whole time. The current won''t change while the EV is being charged.
A 2 A charger isn''t going to produce a higher voltage than a 1 A charger, but it has more current capability. That means it is intended to charge a larger battery, all else being equal. For the best answer, read the datasheet for the particular battery you want to charge and don''t assume it applies to any other battery.
For example, a 2000 mAh battery would ideally have a charging current between 1000 mA (0.5C) and 2000 mA (1C).
