AI Customer ServiceAbstract: This paper presents an overview of the fundamentals of battery chargers, including charging algorithms and circuit implementation of linear and switching battery chargers. First, the basic operation of batteries is described under open circuit, discharging, and charging conditions.
The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
In this tutorial, we are demonstrating a Li-ion Battery Charger Circuit. Li-Ion batteries usually require constant current, constant voltage (CCCV) sort of charging calculation. A Li-Ion battery ought to be charged at a set current level (regulating from 1 to 1.5 amperes) until it arrives at its peak voltage.
The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
For more critical applications, one or more can be combined in a single charger. Peak voltage detection is used in the constant current regulator (CCR) battery charging circuit shown below. Using a peak voltage detection point of 1.5 V/cell will result in charging to about 97% of full capacity for NiMH and NiCd batteries.
The charger senses this and sources maximum current to try to force the battery voltage up. During the current limit phase, the charger must limit the current to the maximum allowed by the manufacturer (shown as 1c here) to prevent damaging the batteries.
