Title: Takahito Ishizuka: Innovator in Battery Charging Technology
Introduction
Takahito Ishizuka is a notable inventor based in Katsuta, Japan. He has made significant contributions to the field of battery charging technology, holding a total of 3 patents. His work focuses on improving the efficiency and safety of battery chargers, particularly in automotive applications.
Latest Patents
One of Ishizuka's latest patents is a battery charger that utilizes a car battery as a power source. This innovative charger interrupts the charging of a rechargeable battery if the car battery remains in a low voltage state for a predetermined period. However, charging resumes once the car battery's voltage returns to an acceptable level before a second time limit is reached. If the low voltage condition persists beyond this second period, charging is halted entirely.
Another significant patent is for a rapid battery charger that features a slow charge mode for low-temperature conditions. This charger can switch between rapid and slow charging modes based on the battery's temperature. When the temperature exceeds a specific threshold, the rapid charge mode is activated, allowing for charging currents greater than 5 C. Conversely, if the temperature falls below this threshold, the charger switches to a slow charge mode, limiting the current to less than 1 C.
