A battery assembly comprises a battery and a battery monitor. The battery has a cover, a post terminal, and a battery near field communication ('NFC') device. The battery NFC device is disposed within the cover adjacent the post terminal. The battery monitor is removably attachable to the post terminal and has a monitor NFC device communicating with the battery NFC device.

An integrated high-performance and light-weight electric drive system for a bicycle is disclosed comprising an integrated unitary motor-controller-drive system that can be inserted into and removed from a first tube portion of a bicycle frame through an open bottom bracket shell portion of the bicycle frame. A longitudinally-extending battery pack configured to be electrically connected with and to provide electrical power to the electric motor and the controller may be configured to be inserted into and removed from a second tube portion of the bicycle frame through the open bottom bracket shell portion of the bicycle frame. Some or all of the electrical components may not be visible from the exterior of the bicycle. A unique digital torque sensing and control system is described along with regenerative braking and other unique features.

A system and method for use in an automated data storage cartridge library defines cartridges for use with an external host computer ('open' cartridges), and cartridges for use only internal to the library ('closed' cartridges). Cartridges may be &#x201c;virtualized&#x201d; by storing data from them on disk or closed cartridges, and then &#x201c;realized&#x201d; by writing data to physical cartridges. Virtual cartridges may be logically exported from one library to another. When new cartridges are introduced to the library, they may be designated with one of multiple designations or uses.

A charging and discharging strategy for a rechargeable battery pack is disclosed. The strategy involves monitoring and learning the battery pack's condition (a cycle life parameter) in terms of its progression through its life cycle. The life cycle parameter may be determined as a function of both time (i.e., the battery pack's age) as well as the number of discharge/recharge cycles. The strategy intentionally under-utilizes the battery during the initial stages of its life, based on the cycle life parameter, by charging it to a first level less then the maximum state of charge. This approach reduces charge voltages, reducing stress on the battery's active materials, thereby increasing its life.

System and method for battery charge control based on a cycle life parameter

A rechargeable multiple cell battery pack has an application associated therewith that draws power from the battery pack. While the battery pack is in operation, voltage, current, state-of-charge (SOC), and impedance data are collected on a per-cell basis and an algorithm is performed to determine a state-of-charge for each individual cell of the battery pack consistent with predetermined criteria. The individual cells are charged to the respective, determined state-of-charge (SOC) levels.

Method for cell balancing for lithium battery systems

A method and apparatus of the present invention are designed to equalize cell-to-cell imbalances in a multi-cell lithium battery system. A time-to-balance parameter is calculated for each cell at the beginning of charge, and balancing occurs for each cell having a positive time-to-balance at the beginning of charge. Alternatively, the time-to-balance parameter is calculated during operation of the battery system and equalization of the cells occur in-sit based on the time-to-balance values.

An energy system is formed of a plurality of battery cells, and has an application associated therewith that draws power from the energy system, thereby creating a load profile that is presented to the energy system. As the application is being used, voltage and current measurements are taken at a predetermined rate, and stored in a history table to create a series of time-based measurements. The measurements stored in the history table are then processed to produce an energy spectra and a power spectra corresponding to the load profile presented to the energy system by the application. A charging strategy in accordance with this energy spectra and power spectra is then defined and used to charge the energy system appropriately.

Method of dynamically charging a battery using load profile parameters

A charging strategy for a rechargeable battery pack is disclosed. The battery pack is used in an application that includes a dynamoelectric machine that may operate as a motor, drawing power from the battery pack, or as a generator, delivering regenerative energy to the battery pack. The strategy monitors the nature, intensity, duration and frequency, among other things, associated with encountered episodes of regenerative energy from the dynamoelectric machine, and adjusts subsequent recharging processes to allow a calculated amount of headroom to accommodate regenerative energy inputs in the future, which may be assumed to be equal in nature, intensity, duration and frequency to what has already been observed. Overcharging is reduced or eliminated, while maximizing the amount of charge on the battery pack, and thus duration of use.

Rechargeable battery pack with adaptive regenerative energy control and method thereof

An energy system is formed of a plurality of battery cells, and has an application associated therewith that draws power from the energy system. As the application is being used, voltage and current measurements are taken at a predetermined rate, and stored in a history table to create a series of time-based measurements. The measurements stored in the history table are then processed to compute an impedance parameter value corresponding to the AC impedance of the energy system This impedance parameter value is then stored in a memory buffer where it can be used to carry out various diagnotic and control functions.

Method of computing AC impedance of an energy system

A vehicle having an electric hybrid power system is provided. A battery pack stores electricity to power the electric motor. The battery pack includes a first plurality of batteries connected in parallel with a second plurality of batteries. The first plurality of batteries are Nickel Metal Hydride (NiMH), and the second plurality of batteries provide high power output at lower temperatures. In addition, the second plurality of batteries may also have a low energy density.
