## Battery Charging Circuit Schematic

Battery charging circuitis a circuit device used to input electrical energy to a rechargeable battery, or some other electrical cells, which have different current levels. The source of this energy filling in the form of DC current from various sources, e.g. from a solar cell known as the solar battery charging, from the car as a car battery charging, and other DC power supply. So in this case a battery charger is a DC to DC power supply.

A battery charger or abattery charging circuitwill conduct an electric current charging by pushing an electric current through it. Charging circuit has a variety of different charge currents depending on the type of rechargeable battery. Because of this then produced various types of the battery charger. For example, a battery charger that comes from car battery power you have different types, if the need to recharge your laptop and cell phone batteries. This is because there is a difference between the current and voltage of 19V to 3.6V at a laptop and cell phone.

Here is some simplebattery charging circuitschematic, which is useful if you intend to build rather than buy. Alternatively, for simply learning how to make a battery charger according to the need for several types of rechargeable batteries such as Lead-Acid batteries, NiMH, Lithium, or 12V battery. Features accompanying the charging circuit is crucial usually disconnected automatically when fully charged, has a charging indicator circuit, and has a fast charging time.

### Solar Battery Charging Circuit

This simplebattery charging circuitusing a typical solar module comprising eight series connected solar cells. Nominal voltage of the module is determined by the number of battery cells to be charged. When active solar panels supply about 140-200mA or more at 8 times the 0.45 V = 3.6 V (depending on the solar panel is used). Connect two diodes in forward bias (cathode connected to ground) when the diode zener value not found. [more]
