Patent number: 10097013Abstract: A battery management system can be provided which can include a plurality of battery management units connected in series and a host controller. Each battery management unit can include a battery cell, an isolation element, and at least one bypass element. The isolation element is connected with the battery cell in series, and the battery cell is isolated by turning off the isolation element. The bypass elements can be in parallel connection with the battery cell and isolation element, and the battery cell is bypassed by turning on the bypass element. A battery management method can include: activating the battery cell of the battery management unit by turning on the isolation element and turning off the bypass elements of the battery management unit; and deactivating the battery cell of the battery management unit by turning off the isolation element and turning on the bypass elements of the battery management unit.Type: GrantFiled: November 25, 2010Date of Patent: October 9, 2018Assignee: CHEEVC LTDInventor: Kenneth Hamilton Norton

Patent number: 9252466Abstract: A battery pack assembly allowing automated single ended bonding directly between a battery cell and a Printed Circuit Board (PCB) is disclosed. The pack assembly comprises: a caddy, soft and malleable pad, plastic cell lattice, PCB, and plurality of ultrasonic wire or ribbon bonds. The pad includes a first group of apertures and is set on the top of battery cells. The cell lattice includes a second group of apertures and is set on the top of the pad. The PCB includes a third group of apertures and is set on the top of the cell lattice. The ultrasonic wire or ribbon bonds directly connect positive and negative contacts of the battery cells with the PCB. A battery pack assembly allowing equalizing of the temperature potentials of every battery cell in the pack is also disclosed. The pack assembly comprises: a phase change material, soft and malleable pad, and caddy.Type: GrantFiled: November 25, 2010Date of Patent: February 2, 2016Assignee: CHEEVC LTD.Inventor: Kenneth Hamilton Norton
