New depolarization nickel cadmium battery automatic charger circuit
New depolarization nickel cadmium battery automatic charger circuit
The structure diagram of the charger is as shown in figure 4-35, the circuit principle is as shown in figure 4-36. The constant current source which is modulated by the V pulse is composed of IC2, it charges the battery. The 10-bit pulse distribution circuit is composed of the IC5A and IC6, the Co port continuously outputs the low level and high level with 5-bit width to control the cut-off and conduction of V1 and this method realizes the constant current pulse charging and stop-charging of the battery. Q1 and Q3 output the high levels with 1-bit width when the Co outputs the high level, and the 1-bit high levels trigger the battery voltage detection circuit which is composed of the IC5B and the discharging current respectively. IC4 supplies precision reference source which is needed by the 3V comparator.
