Electric Car Battery Charger

Electric Car Battery Charger
This is the scheme diagram of electric car battery charger. As shown the circuit is a conventional power supply, followed by a regulator LM338 which is controlled by an operational amplifier which is responsible for controlling the state of charge to detect the precise moment that must stop and actuate the LED indicator. The resistive divider enables three stages, first take the reference voltage for the operational amplifier and, on the other, control the regulator LM338 through the output

12 V Car battery charger based 7812
Description of the 12V battery charger electronic scheme : Below is a very simple circuit that can be used to charge 12v car battery. In this circuit there is installations to control the charging current and voltage. The circuit is based on the circuit MC78T12ABT IC from Freescale. IC is actually a 7812 with a TO-3 package with a capacity of 3A. (more…)

Simple 12 Volt Battery charger

Simple 12 Volt Battery charger
This kind of battery charger circuit will quickly and easily recharge almost every lead acid battery pack.This battery charger supplies maximum current till the current drawn by the battery falls to 150 miliamper. At this point, less voltage will be applied to complete and avoid over charging. Once the lead acid battery is completely charged, this circuit goes off and lights up the led, showing that the battery has completed to be charged. A suitable heat sink should be
