This paper introduces a DC charging pile for new energy electric vehicles. The DC charging pile can expand the charging power through multiple modular charging units in parallel to improve the charging speed. Each charging unit includes Vienna rectifier, DC transformer, and DC converter.
Design of Energy Storage Charging Pile Equipment The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
Simulation waveforms of a new energy electric vehicle charging pile composed of four charging units Figure 8 shows the waveforms of a DC converter composed of three interleaved circuits. The reference current of each circuit is 8.33A, and the reference current of each DC converter is 25A, so the total charging current is 100A.
This DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles. In the future, the DC charging piles with higher power level, high frequency, high eficiency, and high redundancy features will be studied.
This paper introduces a high power, high eficiency, wide voltage output, and high power factor DC charging pile for new energy electric vehicles, which can be connected in parallel with multiple modular charging units to extend the charging power and thus increase the charging speed.
