This charger uses the electric fan program control manifold block BA3105, it masterly uses the timing and wind speed regulating function of the chip, and the current can be used as the charging timing current and the adjustment charging current. The timer can be set to 0.5-7.5 hours by the S2 which is as shown in figure 2-11; the speed adjustment function is switched by S3 of the figure 2-11, and the pin-1, pin-18 and pin-17 relatively output the high level respectively, every output pin controls different constant current source. When you are making the charger, the power can be supplied by 5W, 7.5V transformer.
