A method for balancing voltage for a multi-cell battery system, in which the battery system includes at least two parallel groups of cells connected in series and in which the parallel group of cells includes at least one battery cell, includes: charging the battery system by keeping the voltage of all parallel groups of cells less than or equal to a second threshold voltage value, while at least the voltage of one group of parallel cells is less than or equal to a first threshold voltage; and while at least the voltage of one group of parallel cells is less than or equal to a second threshold voltage; and while the charging current is above a predefined minimal current. The method further includes measuring the voltage of each parallel group of cells while electrical loads are shut off and dissipating energy in each of the parallel group of cells of the amount that is represented by the voltage difference between the individual parallel group of cells and the parallel group of cells with the lowest voltage.

Balancing voltage for a multi-cell battery system

A method for controlling a plurality of battery cells with a control circuit coupled to the plurality of battery cells, includes: supplying the control circuit with electrical energy from the coupled battery cells; determining a number of battery cells coupled to the control circuit; and automatically adapting a power consumption drawn from the battery cells in response to the number of coupled battery cells.

Control circuit and method for controlling a plurality of battery cells based on a determined number of coupled battery cells

A method of communicating with an electric vehicle wherein the method includes a step of installing a communication device in the electric vehicle. The method also includes establishing a connection from the vehicle to a network. The methodology also includes controlling and monitoring a battery in the electric vehicle.

A delivery system for managing security keys uses three key pairs to establish, register, move and revoke rights in a device to view protected information. The first and second key pairs cooperate to establish a secure certificate containing a device public and private key, and the pairs of keys are manipulated to install the appropriate keys in the device and the associated authentication server without ever exposing the keys. Thereafter, in the event of a need to authorize a new device to view content associated with a prior, authorized device, the key pairs are used to revoke the rights of an old device and establish identical viewing rights in the new device.

An electronic reading system is disclosed which allows users to download books and other types of content to a hand-held reader device for viewing. Using software which runs on a personal computer (PC), the user can download titles from Internet sites to the PC. Titles are then automatically transferred to the device when the device is placed in a cradle which is connected to the PC. Using the device's touch-sensitive display and graphical user interface, the user can access various software-implemented features associated with the display and management of the content. One feature is a user-definable hotkey that can be &ldquo;dragged and dropped&rdquo; onto a menu item to create a shortcut to that item. Another feature allows the user to tap twice on a displayed word to cause the device to look the word up in a pre-specified or default reference title, such as a dictionary or an encyclopedia. Another feature allows the user to block a passage on the touch-sensitive display and then specify one or more destinations (email addresses, file folders, fax numbers, printers, etc.) for routing the passage; when the device is subsequently placed in the cradle, the passage is automatically retrieved by the PC and routed to the specified destination(s). The device also implements a user interface feature for allowing the user to rapidly and conveniently adjust the orientation of the displayed title.

One feature is a user-definable hotkey that can be &ldquo;dragged and dropped&rdquo; onto a menu item to create a shortcut to that item. Another feature allows the user to tap twice on a displayed word to cause the device to look the word up in a prespecified or default reference title, such as a dictionary or an encyclopedia. Another feature allows the user to block a passage on the touch-sensitive display and then specify one or more destinations (email addresses, file folders, fax numbers, printers, etc.) for routing the passage; when the device is subsequently placed in the cradle, the passage is automatically retrieved by the PC and routed to the specified destination(s).
