A method of using an intelligent shared battery system

Abstract

The invention discloses a method for using an intelligent shared battery system, and relates to the field of battery control. The method includes: communicating and connecting the electric vehicle body and the shared battery and performing double identification. When the identification is valid, the background system receives the first response signal to perform Analysis; when the analysis is valid, return the first confirmation signal to the electric vehicle body and the shared battery, and respectively control the conduction of the second IGBT module and the first IGBT module, and the shared battery supplies power to the electric vehicle body. The charging cabinet and the shared battery are connected by communication and double-identified. When the identification is valid, the upper-level system receives the second response signal and analyzes it; when the analysis is valid, the second confirmation signal is returned to the charging cabinet and the shared battery. , and respectively control the conduction of the third IGBT module and the first IGBT module, and the charging cabinet body charges the shared battery. This application realizes the shared battery mode, which ensures the safety of the shared battery during charging and power supply.

Description

technical field [0001] The invention relates to the field of battery control, in particular to a method for using an intelligent shared battery system. Background technique [0002] At present, there are some companies in the market that have launched shared electric vehicles, but the shared electric vehicle itself is still a traditional battery and electric vehicle integrated design, which cannot be disassembled. When charging, the charger port can only be directly inserted into the charging port of the electric vehicle. , to charge the internal battery, and the battery is directly welded into the electric vehicle to prevent theft. When the battery life reaches the charging limit, the shared electric vehicle can only be disassembled, which wastes resources. Therefore, the existing shared electric vehicles The emerging shared battery mode cannot be supported.

[0002] At present, there are some companies in the market that have launched shared electric vehicles, but the shared electric vehicle itself is still a traditional battery and electric vehicle integrated design, which cannot be disassembled. When charging, the charger port can only be directly inserted into the charging port of the electric vehicle. , to charge the internal battery, and the battery is directly welded into the electric vehicle to prevent theft. When the battery life reaches the charging limit, the shared electric vehicle can only be disassembled, which wastes resources. Therefore, the existing shared electric vehicles Cannot support the emerging shared battery mode

[0003] With the innovation of the electric vehicle industry, electric vehicles with detachable lithium batteries have appeared in everyone's field of vision. When charging electric vehicles with detachable lithium batteries, because they are worried about putting them in a unified parking lot and charging them with chargers, car owners generally take out the batteries. Next, take it home and charge it. Although it is safer, it cannot support the shared battery mode

Moreover, the cruising range of a detachable lithium battery electric vehicle is generally relatively short. When the owner forgets to charge the electric vehicle, the electric vehicle can only be pushed to the electric vehicle maintenance yard or public charging equipment to charge the vehicle. Generally, the chargers in these occasions can only meet the minimum requirements. The charging requirements, and the charging specification does not match the owner's electric vehicle at all, it is easy to damage the battery life for a long time, and the gain outweighs the gain
