Circuit Schematic LiPo Battery Charger

Charger. - Here is electronic circuit schematic of LiPo Battery Charger with LM324 IC like in Figure 1 below. Li-Po battery or Lithium-Polymer battery is a rechargeable battery based on the Lithium-ion technology enclosed in a flexible pouch. This soft, flexible pouch makes them very light with a compromise in mechanical strength. Li-Po batteries are widely used in applications where weight is a critical factor. The common applications are radio controlled model flight, RC toys, hand held devices etc.

Description

Circuit schematic like in Figure 1 above is Circuit Schematic LiPo Battery Charger. According Circuitstoday site that The Lithium Polymer battery is evolved from the Lithium Metal Batteries.The main difference is that instead of using Lithium salt electrolyte binded in organic solvents like  Ethylene carbonate, Di Methyl Carbonate Di Ethyl Carbonate , Li-Po batteries use polymer electrolytes like Poly Ethylene Oxide, Poly Methyl Methacrylate, Poly Acrilonitrile etc.   The output voltage of Li-Po battery depends up on the technology used behind it. It is 2.7-3.0 V (discharged) to  4.20-4.35 V( charged) for cells based on Lithium Metal Oxides and it is 1.8-2.0 V (discharged) to 3.6-3.8 V (charged) for cells based on Lithium Iron Phosphate. The charging current is usually 1/5 of the mAH rating of the battery.
