How to adjust the voltage of electric car charger
Therefore, the transformer was carefully disassembled and the number of turns of each group of windings was recorded. The number of turns on the secondary side was 18. Because the charging voltage of the 12V battery was about 14V, the winding on the secondary side was removed for 9 turns. After reinstallation, the test found that the output voltage of the charger dropped from 27V to 12.8V. At this time, the resistance of R22 needed to be increased. After the test, the resistance of R22 was finally set at 15kΩ, no-load output of the charger is 14.2V.

Principle of temperature compensation charger
The electric bicycle charger with temperature compensation function includes the basic circuits of rectifier filter, high-voltage switch, voltage conversion and constant current and constant voltage charging controller. Its characteristics are: it also includes temperature compensator circuit, which is mainly composed of temperature sensor D↓[T], inverting differential amplifier A↓[1], inverting differential amplifier A↓[2] and its bridge circuit, the temperature compensator is connected between the voltage converter of the basic circuit and the constant current and constant voltage charging controller, and is integrated into the voltage negative feedback loop of the whole circuit structure with the output voltage of the basic circuit amplifier.

The working principle of electric car charger
220v AC is filtered by T0 bidirectional filter to suppress interference, D1 is rectified into pulsating DC, and then filtered by C11 to form a stable DC of about 300V. U1 is a TL3842 pulse width modulation integrated circuit. Its 5 pins are the negative pole of the power supply, 7 pins are the positive pole of the power supply, and 6 pins are pulse output to directly drive FET Q1(K1358). The 3 pins are limited by a large current. Adjusting the resistance value of R25(2.5 ohms) can adjust the large current of the charger.
