NiCd temperature monitor

The monitor is particularly intended as an aid for fast charging of NiCd batteries. Most commercially available fast chargers have no temperature sensor, although the temperature is an important factor in the fast charging of NiCd batteries. According to manufacturers’ data sheets, temperatures for various states of a NiCd battery should roughly be: (a) 30[…]

Relay fuse

Relay fuse: Simple battery chargers and power supplies are not normally provided with a current limiter. In many cases, however, it would be advantageous if the unit were proof against short-circuits. An electro-mechanical fuse which serves that function and which can be added to the unit is shown in the diagram. There are two variations,[…]
