Embodiment Construction
[0038] The present invention will be further described below in conjunction with accompanying drawing.
[0039] Explanation: The DC / DC unit is an AC-DC conversion device, which belongs to the existing known technology and will not be described in detail. MSP430 series single-chip microcomputer is a 16-bit single-chip microcomputer, which adopts a simplified instruction set structure. The reason why MSP430 single-chip microcomputer has ultra-low power consumption is that it has its own uniqueness in reducing the power supply voltage of the chip and flexible and controllable operating clock. place.
[0040] For the 4 DC / DC units, they are named the first DC / DC unit, the second DC / DC unit, the third DC / DC unit, and the fourth DC / DC unit from left to right; the 4 charging boxes are from left to right They are named as the first charging box, the second charging box, the third charging box, and the fourth charging box in turn; it is just for the convenience of description, and the...

The invention discloses a control method of an electric vehicle intelligent charging pile system. The electric vehicle intelligent charging pile system comprises a centralized AC\DC conversion unit, a first DC bus, four DC / DC units, four charging boxes, a plurality of switching units, a second DC bus, a temperature sensor, a current sensor, a voltage sensor and a controller unit, wherein an input end of the centralized AC\DC conversion unit is connected with a power grid, and an output end is connected with the first DC bus; an input end of each DC / DC unit is connected with the first DC bus; and an output end of each DC / DC unit is connected with an input end of the corresponding charging box. The control method of the electric vehicle intelligent charging pile system is simple, the electric energy consumption of the whole electric vehicle intelligent charging pile system is low, and the electric vehicle intelligent charging pile system is more energy efficient.
Description
[0001] This application is a divisional application of a patent application with an application date of 2015-10-10, an application number of 201510661993.1, and an invention title of an electric vehicle intelligent charging pile system. technical field [0002] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle intelligent charging pile system. Background technique [0003] An electric vehicle is a new type of green and environment-friendly vehicle powered by a vehicle-mounted power supply and driven by a motor to drive the wheels. The on-board power supply of electric vehicles is generally composed of multiple sets of batteries arranged in series or in parallel to improve the power supply capacity of the batteries. Compared with traditional cars, electric vehicles have less impact on the environment, and their prospects are widely optimistic. The most widely used power source for electric vehicles is lead-acid batteries,...
