  • Patent number: 10408884
    Abstract: Trigger pull tracking, charge time estimation, and other features for a power tool battery pack with wireless communication. A battery pack system includes a power tool battery pack and a processor. The battery pack includes a plurality of cells and a voltage sensor connected to the plurality of cells. The processor is in communication with the voltage sensor that detects a voltage across the plurality of cells using the voltage sensor. The processor further converts the voltage across the plurality of cells to a state of charge; determines a charge rate of a charger charging the battery pack; and determines a conversion factor based on the charge rate. The processor then generates a time to full charge of the battery pack based on the state of charge, the charge rate, and the scalar conversion factor. The processor may further generate current traces for the battery pack.

  • Publication number: 20030180606
    Abstract: A battery pack is provided which can be suitably used in a case where charging of a dedicated secondary battery in a portable terminal device is difficult. The battery pack is mounted in a battery mounting section in a portable cellular phone (portable terminal device) proper. In the battery pack, alkaline accumulators are connected in series. Alkaline accumulators generate electromotive forces having a voltage (3V) being lower than that of the dedicated secondary battery. A power source circuit has a boosting-type DC/DC converter which boosts a voltage of the alkaline accumulators being connected in series at a level being same as that of the dedicated secondary battery (for example, 4.5V), and outputs the boosted voltage. An electrical double layer capacitor has a capacity to feed stable power to an internal circuit in which power consumption increases or decreases in a burst manner and is charged by application of an output of the power source circuit and stores the power.

  • Patent number: 4318967
    Abstract: Disposed between the positive electrode and the negative electrode in addition to the separator layer is an electrolyte-impermeable inert film or foil about 5 to 50 microns thick. The film or foil includes a very small current-focusing aperture produced by piercing, punching, or melting. The entire electrolytic current is focused through this aperture. The area of the aperture is at least ten times smaller than the surface area of the separator layer. The thickness l of the film or foil and the radius r.sub.i of the aperture are governed by the relationship 4l/r.sub.i .ltoreq.10. The electrolyte-impermeable film or foil is sealingly clamped between the positive electrode and a sealing ring at the edge of the cell. The film or foil may be of a synthetic resin polymer material, of nickel, or of a nickel alloy. Self-discharge is decreased by the construction of the cell. The cell may be in a flat form without any appreciable decrease in the energy density taking place.
