This utility model discloses a cell balancing system, including a balancing module and a balancing control module. The balancing module includes multiple independently configured isolated power supply units and power supply units that supply power to each isolated power supply unit. Each cell in the cell pack is equipped with an isolated power supply unit, and each isolated power supply unit is connected to a balancing control module. The balancing control module sends independent balancing control signals to each isolated power supply unit. Under the control of the balancing control module, each isolated power supply unit starts or stops charging its corresponding cell, thereby achieving capacity balancing among the cells in the cell pack. The cell pack includes multiple cells connected in series, and the cell pack forms a loop with a bidirectional inverter to achieve charging and discharging operations with the power grid through the bidirectional inverter. The cells are lithium iron phosphate batteries. This utility model can achieve efficient balancing of the cells in the cell pack, with no limit on the number of cells to be balanced, low cost, and is suitable for widespread application.

The invention relates to the technical field of charging station infrastructure pricing schemes, in particular to a charging station pricing method considering flexibility of an electric vehicle and a distributed power supply, and the method comprises the steps: building a comprehensive charging pricing model; the flexibility range of boundary nodes of operators of the power distribution and power transmission system is obtained by using distributed energy; obtaining a balance condition of pricing and profit of the non-cooperative electric vehicle charging stations through a game theory method, and obtaining a pricing model of N electric vehicle charging stations participating in competition in a market sharing environment; and establishing a closed expression of the service price of the electric vehicle charging station along with the profit, and performing mathematical analysis. According to the method, a plurality of electric vehicle charging stations adopt a comprehensive charging pricing model to realize profit maximization, the balance condition of each charging station in the smart power grid is solved in a non-cooperative mode by adopting a game theory method, and the reliability of the profit of each participant during balance is analyzed and researched through the game theory method.

The utility model discloses a filter support, including fixed frame, two active elements, two driven module and transmission part. Active element and driven module all are opposite fixed frame mobile setting, and transmission part is opposite fixed frame rotation setting. Two active elements and two driven module are along annular arrangement, and a driven module is located between two active elements. Active element and transmission part transmission connection, and driven module also with transmission part transmission connection. When active element is opposite fixed frame mobile, can drive transmission part opposite fixed frame rotation, and then promotes driven module to move to the same mobile direction with active element. The structure realizes the cooperation of active element and driven module through transmission part, improves the adjustment flexibility, can better adapt to different caliber lens, reduces the dark corner, satisfies the diversified shooting demand.
