System and method for charging and replacing battery of electric vehicle based on battery autonomous loading and unloading technology

Abstract

The invention discloses a system and a method for charging and replacing a battery of an electric vehicle based on a battery autonomous loading and unloading technology. A vehicle-mounted terminal ora user terminal enables an electric vehicle user to send a battery demand request; an operation service management platform searches an available battery according to the battery demand request and then recommends a battery installation / replacement scheme to the user; the vehicle-mounted terminal or the user terminal confirms the battery installation / replacement scheme according to the recommendedbattery installation / replacement scheme and sends a battery demand confirmation instruction, wherein the instruction comprises a designated area where the determined battery model reaches before a determined time; the operation service management platform sends the battery demand confirmation instruction to the determined battery terminal of the available battery, wherein the determined battery terminal of the available battery is used for controlling the determined available battery to reach a specified area; and the operation service management platform notifies the battery terminal of thepower battery lack of power on the electric vehicle to complete unloading of the power battery in the designated area, and notifies the determined available battery to complete loading of the batteryto the electric vehicle in the designated area.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging and swapping, in particular to an electric vehicle charging and swapping system and method based on battery autonomous loading and unloading technology. Background technique [0002] On the one hand, the popularization and promotion of electric vehicles has greatly reduced my country's dependence on petroleum fuels and promoted the reform of my country's energy structure. On the other hand, it has also helped my country get rid of its long-term dependence on internal combustion engine core technology. However, while electric vehicles bring a green, comfortable and quiet driving experience, they also bring the need for charging and swapping. Compared with the flexibility of fuel vehicles in terms of time and space, the charging and swapping of electric vehicles presents great inconvenience in both time and space, which also inhibits the enthusiasm of a large number of ordinary use...

Problems solved by technology

[0006] 3. AC slow charging

This solution requires companies that provide this service to invest a lot of manpower and material resources to make this charging solution available anytime and anywhere, and it often takes more than half an hour of charging time plus the waiting time for charging cars. While the user's charging location provides freedom, it still cannot help customers solve the problem of charging waiting, and users still need to spend time and energy to complete the charging process

From a technical point of view, the power source of the charging car is either the on-site power generation of the internal combustion engine generator or the discharge of the pre-charged battery pack. The power generation efficiency and multiple power conversion efficiency of the former are uneconomical. In the long run, the The program is also not economically sustainable, but exists more as a temporary emergency measure and is difficult to promote on a large scale
