Publication number: 20240111647Abstract: Testing devices for testing target test devices each composed of one or more battery cells, such as battery cells and battery packs. In some embodiments, a testing device may be considered self-contained in that it may include sufficient onboard systems and features to allow the testing device to conduct testing on one or more target test devices with minimal inputs, such as electrical power, higher-level instructions, and/or control inputs. In some embodiments, a testing device may include an explosion- and/or fire-proof or -resistant enclosure. In some embodiments, components of a testing device may be modularized for easy reconfiguring for different testing and/or different target test devices. In some embodiments, a plurality of testing devices can be controlled by a central testing controller. Related methods and systems are also disclosed.Type: ApplicationFiled: February 2, 2022Publication date: April 4, 2024Inventors: Younggyu Nam, Yong Duan, Yury Matulevich, Wentao Wang, Qichao Hu
