Intelligent management system for electric vehicle charging pile phased battery pack switching

Abstract

The invention discloses an intelligent management system for electric vehicle charging pile phased battery pack switching. The system structurally comprises an electric control workbench, a man-machine interface, a heat dissipation plate groove, a vertical plate supporting base, a charging gun, a cable pipe and a staged battery mechanism. According to the system, the charging gun is matched with the staged battery mechanism, a rapid charging method combining the constant current and the constant voltage of two-stage steps is adopted, a double-tray rotating seat is formed at the bottoms of twopack of batteries, a left wing tray base and a right wing wing tray base are spread for supporting, then first stage and second stage directly-changed voltages are subjected to switching when the voltages are just increased a constant value so as to form the trigger type internal switch rotation effect on a double-resistance-plate sliding frame, a charging gun circuit is guaranteed to stably prevent the condition that the batteries are overheated so as to from forming upper and lower half-section receiving, grouping cooling is conducted so as to reduce the continuous using power, meanwhile, abattery pack forms an intermittent type unloaded state emptying internal circuits during charging and discharging, so that an inner ring is maintained, so that the dual-battery conversion effect of the batteries is guaranteed to be intelligent protected through a charging pile.

Description

technical field [0001] The invention relates to an intelligent management system for staged battery pack shear of electric vehicle charging piles, belonging to the field of charging piles. Background technique [0002] The charging pile station is a functional environment for the supply of electric vehicles and new energy electric vehicles in the community. It forms a regular location allocation management and area division to ensure the reasonable placement of electric vehicles in the community and the reservation of access channels, so that the charging piles are orderly. Convenient to use, such charging pile stations are also practical in large electric bus stations, and the efficiency of vehicle circulation management is high. The disadvantages of the current common technology to be optimized are: [0003] During the continuous conversion of the battery pack of the charging pile into the charging gun and the output of the electric energy cable, continuous short-term char...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent management system for the staged battery pack shearing of electric vehicle charging piles, so as to solve the problem of continuous conversion of electric energy by the battery pack of the charging pile during the input and output process of the cable into the charging gun. , continuous short-term charging will cause the battery load to overheat, which will cause the current and voltage during the charging process to increase and drop sharply, resulting in an unstable charging fluctuation value that affects the stability of the power supply. There is a certain hidden danger of overload leakage, and this surge and sudden drop circuit phenomenon is also due to the lack of steady current load of the battery pack, and the overheating of the body after long-term work, which leads to the chaotic collision of the electrodes of the battery pack, which are hot and over-charged, and easily cause internal circuit damage. Electrostatic friction enters and emits small sparks, which interferes with the copper wire lead-in effect of the integrated board
