Latest Patents

Yoshinaga's latest patents include a power supply system and management device capable of determining the current upper limit for suppressing cell deterioration and ensuring safety. This innovative power supply system, designed for electric vehicles, features a voltage measurement unit that measures the voltage of each cell, ensuring both user convenience and vehicle safety. Additionally, a current measurement unit tracks the current flowing through the cells, while a temperature measurement unit monitors their temperature. The controller determines a current limit value based on these measurements, notifying a higher-level controller in the electric vehicle of the established current limit value.

Another notable patent is the management device and power storage system. This system includes a status signal output circuit that provides a first status signal indicating whether the power storage unit is functioning normally. It also outputs a second status signal, which is a pulse width modulation (PWM) signal based on the power storage unit's status. If an abnormality is detected, the control signal output circuit sends a signal to bring a switch between the power storage unit and the load into an OFF state.
