Latest Patents: Setsuo Shimizu holds a patent for a Charging Control Apparatus. This invention includes a switching circuit designed to control the charging current from a power source to a storage battery. It features a reference voltage that increases with a ramp correlating to the maximum ramp value of a battery's charging characteristic. Additionally, another reference voltage increases over time, corresponding to a lower ramp value. The terminal voltage of the battery is monitored by a voltage sensor, enabling a first comparator to compare the reference voltage with the sensed voltage. Based on this comparison, the ramp of the reference voltage adjusts, and a second comparator further refines the control of the switching circuit. This sophisticated design enhances battery charging efficiency and safety.
