5 A Stable Car Baterry Charger

This Battery Charger circuit  allows you to charge the battery 5A constant current source that stable over time between recharging.

Charging process is accompanied by the emission of diode D1 – AL310A, and D3-AL310B. IC A1 – 142EN2, Transistors: T1, T3 – KT815, T2 – KT819 (radiator), T4 – KT819. Zener: D2 – KS156, D3 – D814V. Resistors R4 and R5 is wound nichrome wire. 220V/15V transformer designed to power 100 W. Current leads (marked on the chart) must cross section of 0.5 mm2. The circuit is protected from short circuit the battery plates.
