How to build car battery charger - All About Circuits
Jan 31, 2022 · A battery charger does not need a huge transformer. Ten amps is good for anything except jump starting. If the transformer weighs two pounds that should be big enough, never go over 5 pounds until you understand fully what you are doing. And always replace the rectifiers with silicon diodes of suitable rating.
Recreating a battery charger to learn LTspice and EasyEDA
Feb 6, 2024 · The removal of the battery means the battery voltage is no longer opposing the charger supply voltage, so there is 1.45V more voltage across the resistor which, from Ohm's law, increases its current. If you want the current to be independent of the battery voltage, you will need an active-circuit (transistors, etc.) constant-current source.
