Patent number: 11509144Abstract: A system for suppressing inrush currents is described. The system may include a negative temperature coefficient (NTC) thermistor and a positive temperature coefficient (PTC) thermistor arranged in series between a power source and a battery system to be charged. At a low temperature, while the PTC thermistor provides only minimal resistance to minimize an inrush current, the NTC thermistor provides increased resistance. As the temperature increases, the resistance provided by the PTC thermistor increases as the resistance from the NTC thermistor decreases. The system may be used in conjunction with a battery charging system has at least one current pathway from the power source to the battery system.Type: GrantFiled: December 13, 2021Date of Patent: November 22, 2022Assignee: Inventus Power, Inc.Inventors: Jianfei Liu, Jujie Xia, Youwu Chen, Zhengyi Zhou
