Centralized control type charger automatic power-off protection system with soft start function

Abstract

The invention discloses a centralized control type charger automatic power-off protection system with a soft start function, which particularly relates to the technical field of chargers. Through setting the user statistics module, the reporting module and the control module, when the user uses the charging pile for many times and causes damage to the charging pile, the data can be stored in the database and the credit of the user is reduced, so that the user can only carry out the operations of plugging and payment when using the charging pile, and when the user damages too many charging piles, the protection system can search responsibilities for the charging pile through the charging pile data of the database and the corresponding public destroying law, so that the protection system not only protects the charging pile, but also can improve the safety awareness of the user in using the charging pile, and reduces the damage probability of the charging pile, and the profit effect of the charging pile and the safety and the service life of the charging pile in use are guaranteed, and the intelligent operation effect of the protection system is improved.

Description

Technical field [0001] The present invention relates to the field of charger, and more specifically, the present invention relates to an automatic power-off protection system for a set-controlled charger with soft start function. Background technique [0002] When the charger performs a charging instrument for the equipment, the charging pile is often used in the manner, and the charging pile refers to a charging device that provides charging services for electric vehicles. It is mainly divided into floor-standing charging piles and wall-shaped charging piles, mainly taken time, calibration, and calculation of the amount of charge. When the charging pile is used, it will often be overloaded, which is because the charging power of the electric vehicle exceeds the power carrying the charging trapping, so that the charging pile is automatically powered off in order to protect the safety of electric vehicles and charging piles. [0003] When the charging pile is powered off, due to a...

Problems solved by technology

[0003] When the charging pile is powered off, since there is usually a large amount of capacitance in the charging pile circuit, a large surge current is required to add voltage to the capacitor instantly. When the charging pile is started again, the voltage is too low or too high. It affects the service life of charging piles, and the existing charging piles often use power-off protection systems to protect them. However, the current power-off protection can only be used for protection during use, and it is difficult to detect the cause of the problem and solve the problem This leads to a substantial increase in the damage rate of charging piles. Not only is it difficult to guarantee the profitability of charging piles, but it is also difficult to guarantee the safety and service life of charging piles.
