Patent number: 10110022Abstract: A battery charging apparatus includes a charging module and a control module. The control module obtains a DIR (dynamic internal resistance) of a battery cell group based on a voltage and a current of the battery cell group, and generates a control signal based on the voltage and the DIR of the battery cell group. The charging module alternates between outputting and not outputting a charge current/voltage to charge the battery cell group based on the control signal.Type: GrantFiled: December 2, 2015Date of Patent: October 23, 2018Assignee: Automotive Research & Testing CenterInventors: Bo-Han Hwang, Deng-He Lin, Chung-Che Huang

Patent number: 9910100Abstract: A battery characteristic determining device includes a control module and a processing module. The control module outputs a control signal when a battery module is in a charging state and an SOC (state of charge) of the battery module reaches a predetermined target value, so as to result in change of a current of the battery module to a predetermined test value for a predetermined test time period. The predetermined test value is such that the change of the current causes a voltage of the battery module to decrease in the predetermined test time period. The processing module obtains a voltage variation of the battery module in the predetermined test time period, and a C rate of the battery module with reference to the voltage variation.Type: GrantFiled: December 19, 2014Date of Patent: March 6, 2018Assignee: AUTOMOTIVE RESEARCH & TESTING CENTERInventors: Bo-Han Hwang, Kuo-Liang Weng, Deng-He Lin
