PURPOSE:To keep the discharge current of a battery constant and to make it possible to discharge at the same time a plurality of batteries by forming a simple circuit with one transistor, three fixed resistances, and contact terminals. CONSTITUTION:An emitter resistance 2 and a base resistance 3 are connected to a transistor 1, and a base voltage source 7 which determines discharge current is connected to these resistances 2, 3. They are connected to objective batteries 6 through a current detecting collector resistance 4 and a battery connecting terminal 5. A collector bias power source 8 is installed between the batteries 6 and the emitter resistance 2. Therefore, the discharge current of the batteries 6 is kept constant and a plurality of batteries 6 are discharged at the same time. |
