Ni-Cd battery charging circuit

Published:2011/4/14 22:11:00 Author:Nicole | Keyword: Ni-Cd battery

In the circuit, R1 is 10Ω, R2 is 200Ω. When the switch is up closed, the charging current is 60mA(constant current); when the switch is down closed, the charging current is 3mA(constant current). The total pressure drop of silicon diodes CR1, CR2 is 1.2V, and the Q1 emitter pressure drop is 0.6V, so the net pressure drop on R1 or R2 is 0.6V. 0.6V divided by the required charging current (using ampere), then it is the resistance of R1 or R2. LED indicates the work state of this charging circuit.   (View)

LM135 Ni-Cd battery fast charging circuit

Published:2011/3/21 0:52:00 Author:Joan | Keyword: Ni-Cd battery, fast charging

The figure is a safe and reliable Ni-Cd battery fast charging circuit. It detects the completion of battery chargeusing Ni-Cd battery case temperature change. In general, it has been already charge 80% of rated capacity when the rechargeable battery temperature rises to 5 ℃. ST1 is used to detect the ambient temperature, ST2 thermal coupled the rechargeable battery are used to detect the battery temperature. The offset terminal of the temperature sensor adjust ST1 output voltage 50mV higher than that of ST2. When the battery temperature exceeds 5 ℃ of the ambient temperature, the comparator LM308 output goes low, LM317change from constant current source state to the voltage source state, the output voltage is only about 2V, Power supply continues to charge the battery only through the R by 50mA small current. The method can save time and will not overcharge.   (View)
