The charger remains in the Charge Complete state and the charging process can be restarted if the voltage drops below some predefined level (8). The charging process can be terminated with an error if a total charge time-out or an operation charge time- out occurs, or if the battery voltage or charge current is higher than the charge termination voltage/current levels (4), (5). The charger from all states jumps to the Wait For Temperature state when the battery temperature is outside the allowed

An effective cell-balancing algorithm during both charge and discharge phases is presented. This charger can be used either as a standalone application to charge a battery pack with two serial connected Li-Ion/Li-Pol batteries or embedded in residential, office, and industrial applications. Introduction A modern portable system requires more operating voltage than a single-cell Lithium-ion (Li-Ion) or Lithium-polymer (Li- Pol) battery can provide. A serial connection results in a pack voltage eq

PWM: Pulse width modulator to regulate the charge current. VREF: Reference voltage source. TIMERs: Several timers are used by the CPU in charge and cell-balancing algorithms. Incremental ADC: Analog-to-digital converter to digitize the analog signals. INAMP: Instrumentation amplifier to measure charge voltage, current, and temperature. AMUX: Analog multiplexers. Figure 3 also contains a two-cell Li-Ion battery pack, a linear regulator (based on Q1, Q2), a cell-balancing circuit (based on Q4, Q5)
