Ralph’s simple battery charger is essentially this simple voltage regulator circuit. He chose the voltage-setting resistors R1 and R2 to give him 2.5 V on the TL431 when the output sees 3.6 V ...

Whether you implemented the circuit yourself, or took the easy way out and picked up one of the dirt cheap modules available online, the battery management IC is simple to work with and gets the ...

Gas pumps rely on mechanical flow control to stop fuel from flowing into a car. EV chargers deal with high-voltage electricity, often at 800 volts or more. Electricity is lazy—it's going to find the ...
