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 user terminal is used for anelectric vehicle user to input information of a specified standby battery and sending a battery use request and to-be-used vehicle information to an operation service management platform; the operation service management platform confirms whether the battery state of the specified battery is available, whether the vehicle information is legal and whether the specified battery is matched with thevehicle information, the specified battery is controlled to be unlocked if so, and otherwise, rejection information is issued and other available battery information is recommended or service is suspended; the user terminal allows the electric vehicle user to guide the specified battery to the position of the electric vehicle; the operation service management platform monitors moving operation ofthe specified battery, locks the specified battery when illegal operation occurs and reports illegal operation information; and the operation service management platform notifies the battery terminalof the power battery lack of power to complete unloading of the power battery, and notifies the battery terminal of the specified battery to complete loading of the battery to the electric vehicle.

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
