Abstract

DC60 (06/01/55) Nickel cadmium battery charger with triangular charge current characteristic. Consists of a DC power supply Serves power to the nickel cadmium battery charging circuit by allowing current to flow through a switch with a closed state and open the circuit. To control energy storage And emit energy of the inductor respectively This causes the current flowing through the inductor to rise and fall. The nature of the current flowing through the inductor is triangular or similar. Triangle waveform The current flowing through the inductor will flow through the current meter and the nickel battery. Cadmium to charge The current meter tells the amount of triangular wave current to Microcontroller In order for the microcontroller to close the circuit and open the circuit of Switch properly A temperature probe is attached to the nickel cadmium battery so the microcontroller can determine the temperature of the battery during charging. Charging the battery Nickel cadmium with triangular waveform characteristics It helps to reduce the temperature of the battery during charging when compared to charging with constant current. The control program is contained in the memory of the Microcontroller Nickel Metal Hydride Battery Charger with triangular charging current features a DC power supply that supplies power to the battery charging circuit. The current flows through a switch in the closed-circuit state and opens the electric circuit to control the energy storage and discharge of the inductor respectively, causing the current flowing through the inductor to increase and decrease characteristics of the current passing through it. The inductor is triangular or similar to a triangular wave, the current passing through the inductor passes through the current meter and the nickel metal hydride battery. The current meter tells the microcontroller the amount of triangular wave current to the microcontroller so that the microcontroller can properly close the circuit and open the switch circuit. The temperature probe is attached to the battery. Nickel Metal Hydride so the microcontroller can know the temperature of the battery during charging.Charging the Nickel Metal Hydride battery with triangular current characteristics reduces the battery temperature. During charging when compared to the tea With constant current charging, the control program is stored in the microcontroller's memory.
