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.
Prolonged operating of the internal components of the charging pile at a high temperature, especially in summer, will cause irreversible damage to the lifetime of components and the insulation performance of cables, as well as thermal failure and aging of rectifier module .
For example, they found that the frequent voltage fluctuations of the distribution grid are directly connected to the charging station, and intense surge impact and high harmonic content may lead to abnormal heating and low operation efficiency of the rectifier module inside the charging pile, and even the operation failure of the charging pile.
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.
Charging piles, the most important supporting facility for charging, are attracting people’s attention. In the charging process, the output voltage of a charging pile is up to several hundred volts. Any failure in the insulation or communication system of charging equipment may lead to charging accidents, even casualties.
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.
