  • Patent number: 11171488
    Abstract: A solar power system may include a solar panel set, a lithium battery set, a first controller, and a second controller. A single-contact switch is electrically connected between the solar panel set and the lithium battery set. When the first controller detects that the generated voltage of the solar panel set reaches a preset threshold value, the first controller is adapted to trigger the first awakening of the lithium battery set by electrically conducting the single-contact switch, thereby brought the lithium battery set out of the low potential protection state. Also, when the second controller detects the voltage of the lithium battery set is not rising after the first awakening of the lithium battery set, the first controller is driven by the second controller to process the second awakening of the lithium battery set through the single-contact switch.

  • Publication number: 20210119481
    Abstract: An intelligent off-peak power distribution system may include a plurality of power consumption ends powered by a plurality of batteries. Each of the batteries is individually programmed with an electronic code, and the batteries are charged by at least a power supply end, and the charging method thereof is to use off-peak power to perform charging during off-peak hour. At least a distribution vehicle is provided to transport the batteries between the power consumption ends and the power supply end, and a smart communication network is communicated with the power consumption ends, the distribution vehicle, and the power supply end. The batteries are available and transported between the power consumption ends by the distribution vehicle so that the distribution vehicle departing from the power supply end is configured to distribute power to more power consumption ends in a single ride, thereby reducing the power and transportation costs.

  • Patent number: 10826320
    Abstract: A solar power system may comprise a solar panel set, a controller, a lithium battery set, and at least a DC load. The controller has a control unit built therein to control a double-contact relay, a single-contact relay, and a transformer. The rated voltage of the solar panel set is higher than the rated voltage of the lithium battery set between 115% and 130%. When the actual voltage of the solar panel set is lower than 115% of the rated voltage of the lithium battery set, the solar panel set is configured to low-loss charge the lithium battery set under the low illumination condition. When the actual voltage of the solar panel set is higher than 115% of the rated voltage of the lithium battery set, the solar panel set under the high illumination condition is adapted to have voltage-drop through the transformer and high-efficiently charge the lithium battery set.
