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

Abstract

The invention discloses an independent electric vehicle charging device based on a mobile energy storage battery. The independent electric vehicle charging device comprises an energy storage chargingbox, a charging gun and a charging control module, wheels facilitating movement of the energy storage charging box are arranged at the bottom of the energy storage charging box, and a battery module is detachably installed in the energy storage charging box; the battery module adopts an energy storage battery capable of charging and discharging, and the energy storage battery charges a vehicle tobe charged through charging. According to the invention, the problems of difficult energization and power distribution capacity increase of the fixed charging pile stay wire are solved, flexible pointdistribution is realized, the limitation of the power stay wire and the geographical position is avoided, the charging requirement of the electric vehicle is met anytime and anywhere, the plurality of battery modules are detachable and replaceable, long-time charging use can be realized, and the time-of-use electricity price can also be utilized, and when the electricity price at night is low, the detached battery module is charged or if the charging is convenient on site, the battery module can be directly charged, so that the economic benefit is greatly improved.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, in particular to an independent electric vehicle charging device and a charging and discharging system 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. At present, the supplementary electricity of electric vehicles is mainly completed by charging piles. The function of charging piles is similar to that of fuel dispensers in gas stations. They can be fixed on the ground or walls, and i...

AI Technical Summary

Problems solved by technology

[0003] However, because the existing charging piles need to be connected to the power grid and are fixed, there are difficulties in connecting the charging piles to the power supply, and are limited by the power cables and geographical location. , field and other parking lots, it will be difficult to arrange the existing fixed charging piles
