Distributed electric vehicle charging device and charging system based on mobile energy storage battery

Abstract

The invention discloses a distributed electric vehicle charging device and charging system based on a mobile energy storage battery. The charging device comprises a main body charging box, a charginggun and a charging and discharging monitoring module; the main body charging box is provided with a charging gun jack, the interior of the main body charging box is provided with a rechargeable energystorage battery module, and the bottom of the main body charging box is provided with wheels facilitating the movement of the main body charging box; and one end of the charging gun jack is connectedwith the power unit, and the other end is used for inserting a charging gun connected with other charging devices. The charging system comprises a host machine and a slave machine, wherein the host machine and the slave machine both adopt the charging device, the host machine and the slave machine are connected in parallel through series connection of the charging gun and the charging gun jack, and the host machine and the slave machine which are connected in parallel output power to a load together through the charging gun of the host machine. According to the invention, flexible point distribution is realized, the transition is convenient, the limitation of electric power stay wires and geographical positions is avoided, and the charging requirement of a high-power vehicle can be met.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, in particular to a distributed electric vehicle charging device based on a mobile energy storage battery. Background technique [0002] With the vigorous development of new energy vehicles, there are more and more new energy vehicles, especially electric vehicles, but the charging problem and mileage anxiety of electric vehicles have always been the bottleneck restricting the development of electric vehicles, especially in the long-distance use of electric vehicles. Convenience and long charging time are the biggest problems faced by electric vehicle users, which greatly affect the experience of electric vehicle users. Moreover, in the electric vehicle market, low-power cars and high-power buses are the mainstream models. When constructing a charging station, it is necessary to consider models that meet different power levels at the same time. If all charging piles are designed for high...

AI Technical Summary

Problems solved by technology

If all charging piles are designed according to high power, there will be a waste of resources when using low power vehicles

At the same time, in some scenarios, the installation space is limited and the installation flexibility of high-power charging piles is insufficient.

In addition, because the existing charging piles need to be connected to the grid and are fixed, there are difficulties in connecting the charging piles to the power grid, and are limited by the power cables and geographical location, and cannot be transferred to achieve flexible layout.
