Abstract: An array substrate, a display device, and a driving circuit are disclosed. The array substrate includes a substrate, a pixel electrode layer disposed on the substrate, a first insulating layer disposed on the substrate, multiple data lines disposed on the first insulating layer, a second insulating layer disposed on the first insulating layer and covering the data lines, a common electrode layer disposed on the second insulating layer, and multiple data signal cancellation lines disposed between the common electrode layer and the first insulating layer. The common electrode layer includes multiple common shield electrode layers. The data signal cancellation lines are disposed in one-to-one correspondence with the data lines. Along the direction from the pixel electrode layer toward the common electrode layer, one common shield electrode layer covers one respective data signal cancellation line and one respective data line.

Abstract: The present application provides an electric energy allocation bus system, including one or more pairs of electric energy allocation buses, which realizes controllable electric quantity transfer among batteries, power generation devices and electrical loads. The electric energy allocation bus system has an electric energy transfer mode between the batteries and the power generation devices called “valley filling” mode; an electric energy transfer between the batteries and the electric loads called “peak clipping” mode; and an electric energy transfer between the power generation devices and the electric loads called “direct power supply” mode. An electric energy allocation method is further provided to realize the controllable electric energy transfer among batteries, power generation devices and electrical loads.

Abstract: The present disclosure discloses a smart battery, an electric energy allocation bus system, a battery charging and discharging method and an electric energy allocation method. The smart battery internally comprises a battery body portion and a control unit. The smart battery can collect various data of the battery, can be communicated with other smart batteries in a battery pack of a same group and a battery pack control system, and can realize electric quantity transfer among smart batteries of the same group through the electric quantity allocation bus, and realize electric quantity transfer among some batteries of a battery pack accessed to the electric energy allocation bus. Besides, controllable processes of charging and discharging, that is, active balanced charging and discharging, can be realized.

Abstract: Disclosed are a mixed battery group and battery grouping method. The mixed battery group forms a battery group via a serial connection between a primary power supply battery sub-group and an auxiliary power supply battery sub-group, wherein a unit voltage rated capacity of the auxiliary power supply battery sub-group is higher than that of the primary power supply battery sub-group. The mixed battery group provides an entire voltage output of a whole battery group to supply power outwards, and also provides one or more auxiliary power supply having a voltage lower than the entire voltage of the whole battery group to supply power outwards.
