Patent number: 9407104Abstract: A charger for recharging the batteries of a portable electronic device even when no external power source is available. A battery or cell is installed within the charger, and when no access is available to a fixed power source into which the charger can be plugged, the internal battery or cell can be used to recharge the electronic device. The internal battery can be a primary battery or a secondary battery. In the latter case, the internal battery can be maintained in a charged state by means of circuitry which, when the charger is plugged into the external power source, charges the internal battery as well as the battery of the electronic device. The external power source can be either an AC power wall socket, in which case the charger includes AC/DC voltage conversion circuits, or a car lighter socket, or the DC output of a conventional wall charger.Type: GrantFiled: August 27, 2012Date of Patent: August 2, 2016Assignee: Tower Semiconductor Ltd.Inventors: Dror Manor, Amnon Saar, Guy Weinstein, Daniel Breiting

Patent number: 8080976Abstract: A battery charge control system including an algorithm for determining whether the battery chemistry of a battery pack for use in a portable electronic device is primary, in which case charging is prevented, or secondary, in which case charging is enabled. The routine operates by measuring the terminal voltage and temperature of the battery under certain predetermined tests, which generally include a combination of voltage and internal impedance tests performed during charge or discharge. Additionally, a method is described to detect and to correct for lack of cell balance within the rechargeable battery pack of a portable electronic device. A cell or cells of the battery pack which are close to depletion, or are completely depleted, are detected, and a discharge/charge routine is executed to provide for optimum recharging of all of the cells of the battery, thus ensuring proper cell balance, and most efficient power usage.Type: GrantFiled: December 11, 2007Date of Patent: December 20, 2011Assignee: Techtium Ltd.Inventors: Dror Manor, Amnon Saar, Guy Weinstein

Patent number: 8004237Abstract: A bidirectional battery charge control system for a portable electronic device which uses a rechargeable main battery. The system enables the connection of an auxiliary battery to the device for inputting additional current to the device. Control of the current flow into and out of the auxiliary battery is performed by a bidirectional charger. The auxiliary battery can contain one or more readily available primary or secondary cells, and the bidirectional charger is such that an external charger connected to the device, generally used to charge the main rechargeable battery of the device, can also recharge a secondary cell or cells in the auxiliary battery, if such are installed. The use of such an auxiliary battery enables the main battery to be hard-wired into the device.Type: GrantFiled: March 10, 2006Date of Patent: August 23, 2011Assignee: Techtium , Ltd.Inventors: Dror Manor, Guy Weinstein

Publication number: 20080284370Abstract: A portable battery-powered power supply or charger for use with electronic devices containing a primary or secondary battery. In order to control the current flow into and out of its battery, the portable power supply uses a bidirectional charge controller. The battery is installed in a housing which preferably has a single connector port to which a flexible current lead may be plugged. The bidirectional charge controller enables the battery either to supply current to the electronic device, to charge the device's internal battery, or it allows the battery, if it is a secondary battery, to be charged by connection to an externally powered charger, such as a wall mains adapter. Both of these functions are achieved through a single connection port.Type: ApplicationFiled: March 10, 2006Publication date: November 20, 2008Applicant: Techtium, Ltd.Inventors: Dror Manor, Guy Weinstein
