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.
Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
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 section, the energy storage charging pile device is designed as a whole.
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 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.
