  • Patent number: 10978887
    Abstract: A fast charging battery system and method for charging battery systems can be applied to most battery types in use for electric vehicles (EVs), electronic devices, and wireless electrical machines. The system could employ industry proven battery charger systems and off-the-shelf electrical components (e.g., contactors, relay switches, semiconductor parts, DC-DC converters, and the like) to keep cost and complexity low. The system provides for two or more charging ports in the electronic device, such as an EV, that may be able to receive and recognize a charging type, such as charging voltage, current and the like, and provide directed charging to multiple battery sub-packs that make up the entire battery. By charging sub-packs in parallel, the charge time can be substantially reduced.

  • Patent number: 10965211
    Abstract: A technology for suppressing a performance degradation of a solar battery caused by PID is provided. A conversion device includes a DC/DC converter and a control part. A solar battery is connected to an input end of the DC/DC converter. When direct-current power generated by the solar battery is converted and output, the DC/DC converter makes a potential of a negative electrode of the solar battery to be higher than a potential in a negative electrode of the output when the power input from the solar battery exceeds a prescribed value. The control part changes a voltage of the power output from the solar battery to detect a peak value of the power, and stops the operation of the DC/DC converter when the peak value is smaller than the prescribed value.

  • Patent number: 10670640
    Abstract: An embodiment relates to a method for predicting a voltage dip in a vehicle electrical system before a planned start of a load in a motor vehicle. The embodiment operates to ascertain a value of supply current expected to be required after the start of the load. An electrical voltage source and an energy store connected in parallel to a voltage source via the vehicle electrical system provide the supply current for operating the load. The energy store blocks a charge current into the energy store or blocks a discharge current out of the energy store based on a vehicle electrical system voltage of the vehicle electrical system being greater than a maximum value. Based on an instantaneous value of the vehicle electrical system voltage, the embodiment further ascertains a proportion of the supply current that the voltage source generates as a source current without the energy store until the vehicle electrical system voltage has fallen to the maximum value.

  • Patent number: 10566663
    Abstract: In a power supply control device, a microcomputer controls the supply of power from a battery to loads via a battery conductor by individually switching on and off switches. While power is being supplied from the battery to the microcomputer, current flows from the positive electrode of the battery to a battery terminal, the battery conductor, a diode, a resistor, a regulator, the microcomputer, an intermediate conductor, a fuse portion, a GND conductor, and a GND terminal in this order. If a current greater than or equal to a predetermined current flows to the fuse portion, the fuse portion breaks.

  • Patent number: 10539990
    Abstract: An information handling system may have multiple batteries and be powered by any one or combination of those batteries. The multiple batteries may be in different detachable portions of the system. When the portions are attached, a battery in one unit connects through multiple input paths to provide power to the other unit. Under a heavy loading condition, power may be drawn from a first battery while power from a second battery is routed to an external power input of the information handling system to supplement power drawn from the first battery.

  • Patent number: 10536015
    Abstract: A fast charging high energy storage capacitor system jump starter is described. The jump starter apparatus incorporates a method of using extracted energy from a battery pack, such as a battery pack used with a portable power tool. The extracted energy is stored at a higher DC potential level by the capacitor system after being boosted or stepped up by a boost/convertor circuit. The stored energy is then available for use in starting a motor vehicle whose vehicle battery as become depleted such that it does not provide enough energy for its intended purposes. The disclosed system and method provide for the motor vehicle battery, combined with a fast charging high energy capacitor bank, to enable the rapid and effective way to jump start a vehicle.
