Patent number: 11318844Abstract: An on-board charging device includes an AC connector, an AC to DC converter and a detection circuit. The AC connector is configured to be connected to an electric vehicle supply equipment (EVSE), so that a protective earth terminal of EVSE is electrically connected to a protective earth terminal of the on-board charging device. The AC to DC converter is electrically connected to the AC connector, and the AC to DC converter is configured to convert an AC voltage provided by the EVSE into a DC voltage. The AC to DC converter has a reference ground terminal. The detection circuit outputs a detection voltage based on the voltage difference between the protective earth terminal of the on-board charging device and the reference ground terminal of the AC to DC converter. The detection voltage reflects whether the protective earth terminal of the EVSE is abnormal or not.Type: GrantFiled: November 14, 2018Date of Patent: May 3, 2022Assignee: DELTA ELECTRONICS, INC.Inventors: Sheng-Nan Tsai, Chia-Cheng Yang, Meng-Fu Cho

Patent number: 11264822Abstract: This application provides a method for determining a charger, a related device, and a system. The method includes: detecting, by an electronic device, a charging current output from a charger; when amplitude values of the charging current are a sequence of variable current, quantifying the current sequence into a binary sequence; determining whether the quantified binary sequence is the same as a prestored binary sequence; and when the quantified binary sequence is different from the prestored binary sequence, outputting prompt information indicating that the charger is a non-standard configuration charger. According to the present invention, whether the charger is a standard configuration charger is determined. This manner is simple and convenient. In addition, no specific device detection module needs to be disposed on the charger.Type: GrantFiled: March 23, 2017Date of Patent: March 1, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jinming Wu, Peng Ding, Yajun Pan

Patent number: 11228193Abstract: An automatically generated and customized fast charging process results in reduced degradation in the battery cell. An algorithm for a particular battery cell profile is automatically generated and customized to minimize degradation due to fast charging for that particular batch. To generate the custom algorithm, battery cell information is retrieved for a profile of a battery, wherein each battery profile may have a particular manufacturer, model, type, electrode batch, and potentially other specific identification information. Each battery cell is charged from a particular SOC level and at a selected C-rate, and then discharged. During discharge, the battery cell is monitored for detection of lithium plating or other undesirable effects. A lookup table is automatically generated from the battery cell information, and can be provided to devices and/or battery management systems. The BMS then uses the lookup table to apply a charging process that is customized to the on-board battery.Type: GrantFiled: December 31, 2018Date of Patent: January 18, 2022Assignee: CHONGQING JINKANG POWERTRAIN NEW ENERGY CO., LTD.Inventors: Brennan Campbell, Saeed Khaleghi Rahimian, Joseph Tolentino, Yifan Tang, Ying Liu
