Title: Innovations of Hideki Watanabe
Introduction
Hideki Watanabe is a notable inventor based in Anjo, Japan, known for his significant contributions to battery charging technology. With a total of three patents to his name, Watanabe has developed innovative solutions aimed at improving the efficiency and safety of battery charging systems.
Latest Patents
Among his latest patents is a groundbreaking battery charger that detects when batteries are fully charged by utilizing a thermostat. This invention involves a charging system capable of accommodating two types of battery packs—a traditional three-terminal type with batteries and a thermostat switch, and a modern four-terminal type that incorporates a thermistor for temperature sensing. The designed charging control circuit ensures that charging current ceases when the thermostat switch contacts are open, or when the thermistor detects temperatures exceeding a predetermined limit. This mechanism is crucial in preventing potential damage to the battery due to overheating or circuit failures.
Another noteworthy patent by Watanabe is the design of a battery charger that accounts for the initial surge in battery voltage. This invention includes a circuit that detects the battery voltage (V1) after a set period (T1) from the initiation of the charging process. The determination of full charge is made once the battery voltage has reached the combination of a predetermined voltage difference (dVS) and the initially detected battery voltage (V1).
