Electric automobile charging device with flexible power distribution function

Abstract

The invention discloses an electric automobile charging device with a flexible power distribution function. The electric automobile charging device comprises a charging pile body, L charging terminalsand a micro-processing chip, L is a positive integer larger than 2, the charging pile body and the charging terminals are designed in a distributed manner, the charging terminals are arranged on charging parking spaces, the charging pile body are electrically connected with the charging terminals through power lines, the micro-processing chip is arranged on the charging pile body, the first signal output end of the micro-processing chip is electrically connected with the signal input end of the charging pile body, and the signal input end of the micro-processing chip is in signal connection with signal output ends of the charging terminals. According to the device, power supplies and charging devices are placed in a distributed manner, objective requirements of the charging parking spacesfor positions are reduced, working noise is reduced, a power control module sufficiently call various power supply modules, the use ratio of the device is ensured, the real power of the device reacha rated value, and power waste is avoided.

Description

technical field [0001] The invention relates to the field of electric vehicle charging equipment, and more specifically, to an electric vehicle charging device with a flexible power distribution function. Background technique [0002] With the rapid development of the pure electric vehicle industry, new energy vehicles are a strategic emerging industry, and the supporting charging facilities are the key to the development of the new energy vehicle industry. Under the vigorous promotion of the country, since 2015, the national standards for charging equipment have been issued and implemented - "GB / T 18487.1-2015 Electric Vehicle Conductive Charging System Part 1 General Requirements", "GB / T 20234.2-2015 Connecting device for conductive charging of electric vehicles Part 2: AC charging interface", "GB / T 20234.3-2015 Connecting device for conductive charging of electric vehicles Part 3: DC charging interface", "GB / T 27930-2015 Off-board conduction of electric vehicles Communic...

AI Technical Summary

Problems solved by technology

[0004] 1. The initial equipment investment cost increases;

[0005] 2. Increased equipment management costs during the operation period;

[0006] 3. The volume of a single charging device is too large;

[0007] 4. The utilization rate of a single charging device is not high;

However, if the realization mechanism of power distribution is not reliable enough, and the interface of function division is not reasonable enough, the maintenance cost of the equipment in the later stage will be extremely high.
