Patent number: 9203068Abstract: A battery pack for a vehicle may include a cell array defining an upper surface and a housing defining a raised portion extending along and above a length of the array such that the raised portion and upper surface define a vent manifold therebetween which may be configured to collect gases generated by the array. The housing may define a discharge opening configured to allow gases to exit the manifold. A pair of end plates may be disposed at opposing ends of the array. One of the end plates may define a pass through portion in at least partial registration with the discharge opening. An outlet tube may be configured to facilitate fluid communication between the vent manifold and exterior of the vehicle. The battery pack may also include spacers located between upper edges of adjacent cells and may be configured to prevent cooling gases from entering the vent manifold.Type: GrantFiled: April 15, 2014Date of Patent: December 1, 2015Assignee: Ford Global Technologies, LLCInventors: Brian Utley, Saravanan Paramasivam, Patrick Daniel Maguire, Steven F.

Patent number: 9026393Abstract: A High Voltage Interlock Strategy (HVIS) uses feedback current to detect cable connectivity status for a high-voltage cable configured to connect a power conversion circuit with a remote permanent magnet synchronous machine (PMSM). One or more feedback factors are calculated based on detected feedback current. Various algorithms for calculating a feedback factor, and for determining connectivity status based on calculated feedback factors, can be practiced, according to the PMSM operational mode. Fault detection action can be performed in response to detecting a cable disconnect. The HVIS can be implemented by software, making it a safe, economical solution for cable connectivity detection.Type: GrantFiled: July 7, 2009Date of Patent: May 5, 2015Assignee: Ford Global Technologies, LLCInventors: Joe Youqing Xiang, Venkateswa Anand Sankaran, Michael W.
