Latest Patents
One of Sangki Lee's latest patents is a "Method for battery management and battery system providing the same." This innovative battery system includes a battery and a battery management system (BMS) that controls the charging of the battery. It operates in two modes: a normal mode using a first battery capacity and an eco-friendly mode using a second battery capacity. The first lower limit state of charge (SOC) is smaller than the second lower limit SOC, while the first upper limit SOC is greater than the second upper limit SOC.
Another significant patent is the "Heat pump system for vehicle." This system features a complex valve device that includes a three-way valve, an on-off valve, expansion means, and connection blocks that are integrally formed. The three-way valve connects to the refrigerant circulation line of the exterior heat exchanger, allowing the refrigerant to selectively bypass it. The on-off valve controls the bypass line, while the expansion means selectively expands refrigerant discharged from the interior heat exchanger. This innovative design allows all functions of the heat pump system to be conducted through the refrigerant control of the complex valve device.
