  • Patent number: 10967750
    Abstract: A system and method for charging a plug-in hybrid vehicle can improve the on-board charging efficiency of the plug-in hybrid vehicle by adjusting a frequency of operation of a cooler when cooling an on-board charger (OBC) by circulating coolant when the temperature of the OBC rises while a high-voltage battery is being charged. The operations of a water pump and a radiator fan are controlled by determining whether the voltage of the high-voltage battery is within or out of a reference voltage range in which the on-board charging of the high-voltage battery is performed. This consequently prevents power from being unnecessarily consumed by operation of the cooler, such that the efficiency of charging is improved and the OBC is properly cooled.

  • Patent number: 10941289
    Abstract: A graft copolymer, a thermoplastic resin composition including the graft copolymer, and a method of preparing the thermoplastic resin composition are described herein. A graft copolymer having a shell in which silica modified with a specific compound is dispersed within a specific content range, a thermoplastic resin composition including the graft copolymer, and a method of preparing the thermoplastic resin composition are also described herein. Since silica modified with a specific compound is dispersed in the periphery of rubber particles, that is, in the shell of the graft copolymer, the dispersibility of the graft copolymer may be improved. Therefore, the graft copolymer may have transparency equal to or better than a conventional graft copolymer. In addition, compared to a resin composition having an equivalent rubber content, the thermoplastic resin composition described herein may have excellent physical properties, such as impact strength and tensile strength.
