摘要:
A rechargeable multiple cell battery (10) pack has an application (12) 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 (30) are charged to the respective, determined state-of-charge (SOC) levels.

Methods and systems for boosting battery output comprising a supercapacitor that is connected in series with a voltage source in series with a load are disclosed The supercapacitor may be charged to a regulated and monitored voltage via a booster circuit The methods and systems are usefully applied to high pulse draw applications, such as cell phones or camera flash lamps, or to supplement battery voltage under adverse conditions, such as a vehicle battery applied to start a motor in cold temperatures.
摘要:
The present invention falls within the field of video signal conversion, and discloses a hub with a pluggable mobile power supply, the hub comprising the mobile power supply and a hub, wherein the mobile power supply comprises a first connector, a first direct current conversion module, a charging and discharging management module, a second direct current conversion module, a second connector, and an electric cell; and wherein the hub comprises a third connector, a fourth connector, a power supply management module, a fifth connector, a video signal conversion module, and a sixth connector, the second connector being connected to the fourth connector when a power adapter is not connected to the third connector. Because the hub is provided with the fourth connector that may be connected to the mobile power supply, power is supplied by means of the mobile power supply when the hub is not connected to the power adapter, thereby improving the convenience of the hub.

The present disclosure discloses a wireless power transmission device including a first coil and a second coil electromagnetically coupled to the first coil without contacting therewith. At least a portion of one of the first coil and the second coil passes through at least a portion of a space defined by the other of the first coil and the second coil. In the present disclosure, since one of a transmitting coil and a receiving coil passes through the other of the transmitting coil and the receiving coil, strength of electromagnetic coupling between the two coils can be improved so as to increase the strength of electromagnetic coupling between the coils without increasing sizes thereof.

Disclosed is a battery having an internally integrated voltage converter module. The battery includes at least one electrochemical cell having an internal bore, a voltage converter module electrically coupled to the at least one electrochemical cell and disposed within a portion of the internal bore, the voltage converter configured to convert a first voltage produced by the at least one electrochemical cell into a second, different voltage, a set of terminals being electrically coupled to the voltage converter, and a bypass circuit coupled between one of the terminals of the set of terminals and the at least one electrochemical cell to direct charging current applied from an external source to the at least one electrochemical cell.
摘要:
The invention relates to a microwave generator which comprises a housing having two opposite electrodes, separated by an electrode gap filled with a dielectric, and a spark gap in between the two electrodes which sparks, thereby emitting microwaves, when a high voltage is applied. In order to modify the microwave frequency, the electrode gap (13, 13a, 13b) can at least be partially filled with a second dielectric (15, 15a, 15b) having a permittivity that is different from that of the first dielectric (14, 14a, 14b), present between the electrodes (6, 7). The second dielectric (15, 15a, 15b) is stored in a reservoir (17, 17a, 17b) which communicates with the electrode gap (13, 13a, 13b).
摘要:
There is provided a metallic tape supporting a mercury vapour releasing material, preferably Ti₃Hg, admixed with a non-evaporable getter metal, preferably an alloy of 84% Zr - 16% Al, contained within a continuous series of depressions within the tape. The depressions form a successive series of pairs of depressions preferably each having an oval shape. Each pair of oval shaped depressions is separated by a distance greater than the distance separating the individual oval shapes. The tape can then be cut between each pair of depressions to form a small strip containing two depressions. Such a small strip can then be folded through an angle of approximately 180° about an axis, in the plane of the tape midway between the depressions, perpendicular to the tape length. This folded strip can then be welded to a support and used as a cold cathode electrode in a miniature fluorescent lamp. The cathode can be heated during a manufacturing process to release mercury and subsequently act as a cold cathode and getter device.
