The working principle of intelligent charger：

Rechargeable battery with high performance and low cost, large discharge current, long life and other characteristics, widely used in all kinds of communications equipment, instruments and meters, electrical measuring device.But different types of batteries, such as nickel cadmium (Nicd), nickel metal hydride batteries (NiMH) batteries and lithium ion batteries have different charging characteristics and process.Different battery should adopt different charging control technology.Commonly used control technology are: voltage negative incremental control, time control, temperature control, high voltage control technology, etc.The voltage negative incremental control is now recognized as one of the advanced control method.

The working principle of: charger, when the measured battery voltage negative incremental can determine when the battery is full of, which will turn into a trickle charging charging.Time control charging time, when charging time to make the charger to stop or turn to a trickle charging, this method is safe.Temperature control is to achieve the full state when the battery cell temperature rise faster, measuring the temperature of the battery or the change of temperature, so as to determine whether to stop charging the battery.The highest voltage control is judged according to the allowable voltage rechargeable batteries charging status, this method has good flexibility.
