Embodiment Construction

[0028] Such as figure 1 , The chain charging system of electric vehicles is composed of N subsystems and N link units; the subsystem includes 3 power zones composed of power modules, 1 power distribution unit, 3 inner loop control units, and charging terminal devices. The method for dynamically allocating power of an electric vehicle includes the following steps: the charging terminal 1 of the subsystem N is connected to the electric vehicle, the charging demand information of the electric vehicle is obtained and transmitted to the power distribution unit of the subsystem N, and the power distribution unit of the subsystem N is based on the system The working state of the power area, calculate whether the idle power of the power area in the subsystem N can meet the power demand of the vehicle, and if so, dynamically allocate the idle power area through the power distribution unit in the subsystem N to complete the adjustment of the output bus of the power supply module , and c...

Description

technical field [0001] The invention relates to the field of electric vehicle charging, and relates to a link charging system and a method for dynamically distributing power. Background technique [0002] The automobile industry is the second largest industry after petrochemical industry in the world. At present, most automobiles use gasoline and diesel as fuel, which not only consumes a large amount of oil resources, but also the nitrogen oxides and hydrocarbons contained in automobile exhaust pollutants, carbon monoxide, etc. have caused serious air pollution. In order to maintain the sustainable development of the national economy, protect the human living environment and ensure energy supply, governments around the world have invested a lot of manpower and material resources to find various ways to solve these problems. At present, there are mainly two ways to save energy, one is a hybrid vehicle, and the other is a pure electric vehicle. Compared with traditional vehi...
