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.
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.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
For instance, the APP of TELD, that is, a leading charging facility manufacturer and operator in China, claims that the DC charging pile's advertised charging power of 60–150 kW is 60 kW, but the highest charging power it is capable of is about 90–100 kW.
The power supply and distribution system, charging system, monitoring system, energy storage system, and photovoltaic power generation system are the five essential components of the PV and storage integrated fast charging stations. The battery for energy storage, DC charging piles, and PV comprise its three main components.
This demonstrates that using energy storage facilities at the charging station can effectively alleviate the grid's load during peak electricity consumption. Fig. 8. Daily electricity requirements for electric vehicles during peak hours at charging stations.
