    摘要: A battery pack can include one or more battery cells, current blocking transistors and a battery management system. The disclosed implementations handle over-currents drawn from the battery cells that cause unstable operation of the battery management system. The over-currents are handled without causing an undesired drop in voltage output from the battery cells. The disclosed implementations can handle over-currents even if the over-currents cause the battery management system supply voltage to drop below a minimum operating voltage level for a certain period of time. The disclosed implementations use current blocking transistors that can be configured to block current flow and ensure safe operation of the battery cells in cases where the current drawn from the battery cells would be sufficiently high for a sufficiently long period of time to cause damage to the battery cells.

    摘要: In the present invention, a battery pack type discriminating or deciding concave portion (131) is formed at a position corresponding to a battery pack type deciding switch (214) of an SQ battery pack (1) and when the SQ battery pack (1) is set, the battery pack type deciding switch (214) is avoided to be pressed by a bottom (115) of the SQ battery pack (1) owing to the concave portion (131). In this way, as the switch (214) is avoided to be pressed, it is recognized that the set battery pack is an SQ battery pack (1) under charging. Therefore, according to the present invention, it is possible to identify battery packs among different charging modes and charging can be performed in a proper charging mode.

    摘要: A remaining battery capacity indicating apparatus includes an end voltage accumulated value setting unit operable to set an accumulated value indicative of a remaining capacity of a lithium-ion secondary battery, the accumulated value being set in a fully charged state of the battery so that the accumulated value reaches zero when a voltage in the battery is a device-side end voltage. It is determined whether a battery-side end voltage which ends discharges from the lithium-ion secondary battery corresponds to the device-side end voltage. If the battery-side end voltage does not correspond to the device-side end voltage, then the accumulated value is corrected in response to the device-side end voltage. A remaining capacity of the battery, corresponding to the device-side end voltage, is calculated based on the corrected accumulated value, and the calculated remaining capacity of the battery is displayed on a display unit. If the device-side end voltage does not correspond to the battery-side end voltage, then the remaining capacity of the battery is displayed on the device side.

    摘要: A process for producing a hydrogenated polymer, which includes a step of hydrogenating aromatic rings of an aromatic vinyl compound—(meth)acrylate copolymer. In the process, the copolymer having a ratio, A/B, of from 0.25 to 4.0 (A is a molar number of constitutional units derived from the (meth)acrylate monomer, and B is a molar number of constitutional units derived from the aromatic vinyl monomer) is hydrogenated in a solvent in the presence of a catalyst which is composed of zirconium oxide supporting palladium. By the process, a highly transparent, hydrogenated polymer is stably and rapidly produced for a long period of time or repeatedly.
