Ultra Fast Battery charger circuit

Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad] which will be discussed in this article is Fast NiCad Battery Charger, called the Ultra Fast Charger Battery Charger NiCad because it can make filling fast NiCad Batteries Cell. A battery charger in Desai has a fast charging capabilities such as Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad] on this article shall be equipped with some ability to protect the battery and charger circuit itself.

Feature owned by Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad] 

  • Autoshut-off, is the ability of the charger to stop charging current to a NiCad battery if the capacity NiCad battery is fully charged.
  • Polarity Protection, with the existence of this capability so if there are mounting the battery on the charger upside yan can be known.
  • Constant output voltage
  • Output currents enough to fill some NiCad batteries at once in parallel.
  • Short Circuit Protection, with the existence of this protection circuit so if there is short-circuit caused by a battery and a charger circuit itself will not damage the other parts are not damaged.
  • Series Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad]



Image series above is a series of schematic drawings for Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad]. Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad] can be used for 8 to 10 NiCad batteries at once with 12 volt output voltage and max current is 3.5 A. The main components in the circuit of Ultra Fast Battery Chager for Nickel-Cadmium battery cells [NiCad] is UC3843 and MC34181. UC3843 chip is a voltage regulator and M34181 is a JFET OpAmp with characteristic low offset voltage, input impedance is very high. MC34181 serves as a voltage comparator.
