The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
As the electric vehicle charging pile (bolt) on the power distribution side of the power grid, its structure determines that the characteristics of the automatic communication system are many and scattered measured points, wide coverage, and short communication distance.
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.
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.
k) The charging pile (bolt) should monitor the state of the battery, and automatically adjust according to the temperature of the battery, the voltage to the charging curve, the charging current, and the charging voltage;
In [5, 6], the rectifier of the DC charging pile is an uncontrollable rectifier. When the uncontrollable rectifier works, it will inject large harmonic current into the AC grid, the harmonic current will affect the service life of the input transformer, increase the power grid loss, and cause voltage fluctuation.
