Publication number: 20210218093Abstract: The present disclosure provides an electrochemical energy storage device including a housing. The housing includes a first side wall and a second side wall opposite to the first side wall, and defines a chamber configured for receiving a battery cell. The chamber is between the first side wall and the second side wall. At least one of the first side wall and the second side wall carries a reinforcing layer.

Publication number: 20190222097Abstract: A PCB-integrated electromagnetic-induction-principle-based power-line magnetic field energy harvester includes a PCB, the PCB including a substrate and a coil; a rotatable permanent magnet assembly, rotatably embedded in the middle through hole; and a fixed permanent magnet arranged opposite the rotatable permanent magnet assembly and providing the rotatable permanent magnet assembly with a direct current bias magnet field. The PCB-integrated electromagnetic-induction-principle-based power-line magnetic field energy harvester is driven by both of the AC magnetic field generated by the power line and the DC bias magnetic field generated by the fixed permanent magnet. The magnetic field energy around the power line is thus converted into the mechanical energy of the rotatable permanent magnet. The mechanical energy is then converted into the electric energy in the coil. The electric energy is supplied to the following low-power electronic devices (e.g. sensors) in a power transmission system.Type: ApplicationFiled: July 27, 2017Publication date: July 18, 2019Inventors: Jun HU, Zhongxu WANG, Jinliang HE, Shanxiang WANG
