Electric automobile energy storage mobile charging pile and system

Abstract

An electric automobile energy storage mobile charging pile and system comprise a charging pile body, and further comprises a battery module located on the charging pile body, a BMS circuit set, an inverter circuit, a charging metering module, a wireless data module, a positioning module and a main control management module; the battery module is provided with a plurality of battery packs which areconnected in parallel; the BMS circuit set comprises a plurality of BMS circuits which are connected in parallel and are connected with the plurality of battery packs in a one-to-one correspondence mode; the inverter circuit is connected with the battery module to be converted to generate a slow charging voltage current or a fast charging voltage current; the charging metering module is connectedwith the inverter circuit; the wireless data module is connected with the main control management module to send related information or receive control information; the positioning module is connected with the main control management module to provide position information; and the main control management module is connected with the battery module and the charging metering module. According to the invention, a special charging parking space is not needed, and energy storage and charging can be carried out by utilizing the valley-hour electricity price, the problem of power grid capacity is solved, the charging economical efficiency, the power grid balance are facilitated, and the charging cost is low.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an electric vehicle energy storage mobile charging pile and system. Background technique [0002] With the rapid development of pure electric vehicles, the biggest bottleneck has gradually emerged, which is the difficulty of charging and the installation and installation of charging piles. This difficulty is like the chicken-and-egg problem that restricts the popularization and consumption of electric vehicles. [0003] The function of the charging pile is similar to the refueling machine in the gas station. It is generally fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Levels charge various models of electric vehicles. Its characteristic is that the line is provided by the grid, the input end of the charging pile is directly connected to...

AI Technical Summary

Problems solved by technology

Especially for DC fast charging, the general power is tens of KW or even hundreds of KW, so it can only be used for public charging piles. Generally, such capacity cannot be provided for parking lots in residential areas, and only AC slow charging piles can be installed.

However, the AC slow charging pile also needs a few KW of power, so it cannot meet the needs of all users. According to the current standard, it can only meet 20% of the demand, and it cannot even be installed in old communities.
