Patent number: 11658369Abstract: A prismatic lithium ion battery cell includes a packaging having a cover. The cover includes: a first spiral disk feature disposed below a first terminal pad; a second spiral disk feature disposed below a second terminal pad; a first reversal disk disposed below the first spiral disk feature; and a second reversal disk disposed below the second spiral disk feature. The first and second reversal disks are configured to deflect upwards to displace the first and second spiral disk features to contact the first and second terminal pads, respectively, in response to a pressure within the packaging being greater than a predefined pressure threshold and form an external short-circuit between the first and second terminal pads via the first and second spiral disk features. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow between the first and second terminal pads.Type: GrantFiled: June 24, 2022Date of Patent: May 23, 2023Assignee: CPS TECHNOLOGY HOLDINGS LLCInventor: Xugang Zhang

Patent number: 11594792Abstract: A prismatic lithium ion battery cell includes a packaging having a cover. A power assembly disposed within the packaging has a first (e.g., negative) side and a second (e.g., positive) side. A terminal pad is electrically coupled to the first side, while the cover is electrically coupled to the second side, of the power assembly. The cover includes a spiral disk feature disposed below the terminal pad and a reversal disk disposed below the spiral disk feature. The reversal disk is configured to deflect upwards to displace the spiral disk feature to contact the terminal pad in response to a pressure within the packaging being greater than a first predefined pressure threshold, forming an external short-circuit between the first and second sides of the power assembly. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow within the power assembly.Type: GrantFiled: January 3, 2022Date of Patent: February 28, 2023Assignee: CPS TECHNOLOGY HOLDINGS LLCInventor: Xugang Zhang

Patent number: 11571989Abstract: A module-based framework evaluates designs of advanced start stop systems, particularly 12 V advanced start stop systems. The framework separates vehicle and battery analysis and uses a power profile to evaluate different designs of the vehicles and batteries. Particularly, the framework can evaluate different battery solutions and compare performances as a function of drive cycles, motor size, and electrical loads. In addition to modeling, actual batteries are tested for the same power inputs for validating performance differences. This framework identifies performance limiting components for determination of the vehicle system component optimization.Type: GrantFiled: July 27, 2020Date of Patent: February 7, 2023Assignee: CPS Technology Holdings LLCInventors: Zhenli Zhang, Zhihong Jin, Tom M.
