  • Patent number: 11072257
    Abstract: A switch control apparatus capable of effectively controlling a switch during a process of controlling the switch provided in a battery pack. When the switch is shifted from a closed state to an open state, the current caused by the generated counter electromotive force is quickly released, thereby quickly shifting the switch to turn on or off. In addition, since the voltage applied to the control unit falls within the rated voltage range, the stability of the switch control circuit may be enhanced.

  • Patent number: 11063469
    Abstract: Uninterruptible power supply system and method for reconditioning an exhausted battery module, wherein a terminal voltage of the battery module is determined and compared with a predefinable threshold value after starting a network-side supply, where after a waiting time has elapsed, when the threshold value is fallen below, an inverse polarity protection unit is activated for a time pulse, such that when communication between the base unit and the battery module occurs, the inverse polarity protection unit is permanently switched on and a voltage drop is determined and compared within the battery module with a predefined minimum voltage, and if at least one determined voltage drop falls below the predefined minimum voltage, then a predefined charging voltage is applied to the battery module until either a predefinable period of time is exceeded or a predefinable current value is surpassed by a charging current determined in the base unit.

  • Patent number: 11063432
    Abstract: In the present legacy electrical power generation and distribution system, the power quality delivered to end consumers is being degraded by a number of disruptive technologies and legislative impacts; especially with the rapidly increasing myriad of privately owned and operated domestic and commercial distributed energy generation (DEG) devices connected at any point across a low voltage (LV) distribution network. The present invention bypasses this increasing critical DEG problem by offering a solution comprising an energy processing unit (EPU) that is installed at the edge of the high voltage (HV) transmission grid.

  • Patent number: 11018509
    Abstract: A current meter measures a current value associated with input power inputted to a code modulator. A code modulation circuit modulates the input power to generate a code-modulated wave by code modulation using a modulation code based on a code sequence, and transmits the code-modulated wave to the code demodulator via a transmission path. A control circuit controls the code modulation circuit. The code modulation circuit has operation modes different from each other depending on a direction of the input power, and a direction of the code-modulated wave to be generated. The control circuit generates waveform information indicating variations of direction of the input power over time, based on the current value measured by the current meter, and determines the operation mode of the code modulation circuit based on the waveform information.
