“RAZLAGALSA” BATTERY

On the recommendation of the manufacturer to eliminate the memory effect of Nickel-cadmium batteries (NiCd) should clear their element to 0.4 V. For the implementation of the above requirements and automate the process of disconnecting the battery reaches level 0.4 V the authors propose a simple device.

To reduce the disconnection threshold of the discharge transistor /T2 is selected with a high rate of current transfer. The load (in addition to the resistor R2) and at the same time an indicator is incandescent НL with a voltage of 1 V at a current of 75 mA. In the absence of a low-voltage light bulbs a consumer may be led АЛ307Б.

For the battery of certain capacity creates its own corresponding schema discharge. Figure 2 shows a diagram of the discharge 12-volt lead-acid car battery. These also have “memory” and, therefore, before charging each Bank should also discharge to a voltage of 1 V. For this purpose, an automatic device is disabled at the end of the charge, used a relay with powerful contacts, allowing current of at least 20 A. relay Type plays no role. It is important only that the voltage drop of the contact he was about 6 V. the load is used the bulb from the headlamp. The authors did not use the SV1: it was enough to click on the anchor relay, which cap is removed (photo 1).
