The invention provides an automatic battery adjusting unit and an automatic battery balancing system. The automatic battery adjusting unit comprises a common mode choke coil, a switch device and a first control unit. The common mode choke coil comprises an input side and an output side, wherein the input side is coupled with the power supply device. The switch device comprises a first input point,a second input point, a first output point, a second output point and a third output point. The first output point is coupled to the first battery pack, the second output point is coupled to the second battery pack, and the third output point is a null contact. The first control unit compares the first terminal voltage of the first output point with the second terminal voltage of the second output point so as to control the first input point to be selectively connected with the first output point or the second output point and control the second input point to be selectively connected with the second output point or the third output point.
Description
technical field [0001] The invention relates to a battery regulating device, in particular to a battery automatic regulating unit and a battery automatic balancing system applied in a power system. Background technique [0002] With the development of different markets, such as: electric vehicles (Electrical Vehicle), charging stations, etc., the application of power systems is also getting more and more attention. The power system includes multiple battery packs, and these battery packs are connected in series / parallel. In this way, the power system can provide devices with different power requirements. Taking an electric vehicle as an example, the electric power required by a general electric vehicle is a DC power supply, and the working voltage of the electric vehicle is about 300-500 volts. However, when the battery packs in the electric power system of the electric vehicle are supplying power, there will be a phenomenon of power imbalance among multiple battery packs....
