Latest Patents

Tamaki's latest patents include a backup power supply device and a method for controlling a backup power supply device. The first patent provides a backup power supply that efficiently supplies power under the control of a microcomputer. This system is charged by a rectifier that generates power at a predetermined voltage. It supplies power to a load device when the supplied power is insufficient. The backup power supply features a secondary battery charged by the rectifier, a control unit for managing the charging and discharging of the battery, and an input/output voltage detection unit to monitor the output voltage from the rectifier. The control unit is designed to stop charging or reduce the charging current when the output voltage drops below a certain threshold.

The second patent describes a backup power supply device with a short charging time. This device is intended to supply power during a main power supply failure. It includes first and second battery packs connected in parallel, a charging circuit, and discharging switches for each battery pack. The control unit compares the battery voltages with the output voltage from the main power supply. It activates the discharging switches when the battery voltages are lower than the output voltage. Once the battery packs are fully charged, the control unit manages the discharging process based on the battery voltage levels.
