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.
Electric vehicle charging piles employ several common heat dissipation methods to effectively manage the heat generated during the charging process. These methods include: 1. Air Cooling: Air cooling is one of the simplest and most commonly used methods for heat dissipation in EV charging piles.
At present, the charging piles popular in the industry use air-cooled heat dissipation modules. They use a high-speed fan to exhaust the air powerfully. The air is sucked in from the front panel and discharged from the rear of the module, thereby taking away the heat from the radiator and heating components.
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.
It involves using fans or natural convection to circulate air around heat-generating components such as transformers, power electronics, and connectors. Adding heat sinks or radiators to the design of EV charging pile components increases the surface area for heat dissipation and improves airflow.
It can be aided by liquid cooling solutions. A new DC High Power Charging (HPC) solution for EV charging stations has recently been introduced, which uses liquid cooling. This cannon’s unit can deliver a charge of 500A at 1,000V for up to five minutes, allowing for a 60-mile range. This improves the user’s performance as well as their safety.
