8.4 Battery Charger

Figure 8.3 illustrates a temperature compensated battery charger for applications with lead acid

batteries. Diode D1, placed between the power supply and battery, blocks current from flowing

from the battery to the power supply. This eliminates any loading on the battery when the power

supply is off, but more importantly, prevents the battery from charging the power supply’s output

capacitors. With deployment of diode D1, remote sensing should be applied across the battery

terminals to compensate for the diode drop. By setting the voltage and current to the bulk charge

voltage and maximum charge current, the power supply will initially charge the batteries in

current mode control and then automatically crossover to voltage mode control when the batteries

reach the desired set point. Using remote programming features, the power supply can be

programmed for time dependent, sequential step operation to equalize and float charge the

batteries after bulk charging. Equalization is generally not required for every charge cycle. Table
