Universal charge algorithm for telecommunication batteries

Three chemistries are used extensively in today´s portable telecommunication devices: nickel-cadmium, nickel-metal hydride, and lithium-ion. Nickel-cadmium and nickel-metal hydride batteries (also referred to as nickel-based batteries) are well known while lithium-ion batteries are less known. An universal charging algorithm should satisfactorily charge all chemistries while providing recognition among them. Total Battery Management, Inc. (TBM) has developed individual charging algorithms for nickel-based and lithium-ion batteries and a procedure for recognition, if necessary, to incorporate in an universal algorithm. TBM´s charging philosophy is the first to understand the battery from the chemical point of view and then provide an electronic solution
