  • Patent number: 10983779
    Abstract: A system upgrade assessment method based on system parameter correlation coefficients is provided. The problem that the existing system upgrade assessment method cannot accurately assess an upgraded system is solved. For such a purpose, the system upgrade assessment method comprises the following steps: acquiring first data for a plurality of parameters before system upgrade (S110); acquiring second data for the plurality of parameters after the system upgrade (S120); calculating first correlation coefficients of the first data and second correlation coefficients of the second data (S130); calculating third correlation coefficients between the first data and the corresponding second data (S140); and determining, based on the magnitudes of the first correlation coefficients, the second correlation coefficients and the third correlation coefficients, whether the system upgrade succeeds (S150).

  • 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.
