Charging and exchange integrated power battery system, working method and application

Abstract

The invention discloses a charging and exchange integrated power battery system, a working method and application. The charging and exchange integrated power battery system comprises a fixed power battery pack and at least one exchange power battery pack. The power output terminal of the fixed power battery pack and the power output terminal of the exchange power battery pack are connected to thepower input terminal of a driving motor, and connected to the power input terminal of an auxiliary power source through a DCDC module. The power output terminal of the auxiliary power source is connected to the power input terminal of a fixed power battery management system, the power input terminal of an exchange power battery management system and the power input terminal of a main controller. The main controller performs information interaction with the fixed power battery management system, the exchange power battery management system and the DCDC module. Information interaction is performed between the fixed power battery management system and the fixed power battery pack. Information interaction is performed between the exchange power battery management system and the exchange powerbattery pack. Electric vehicles can be quickly charged, the volume of the power battery packs is expanded, the mileage of electric vehicles is increased, the mileage anxiety is relieved, and the driving experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a power battery system integrating charging and swapping, a working method and an application thereof. Background technique [0002] SOC (state of charge) refers to the state of charge of the battery, which is used to indicate the value of the battery power, and is generally expressed in percentage; because electric vehicles use different power devices from traditional fuel vehicles, the internal space of electric vehicles Compared with traditional cars, it has advantages, such as Tesla and other cars have a lot of storage space. [0003] Existing pure electric vehicles usually have a power battery fixedly installed on the chassis. When the battery energy is about to run out, the user can only choose to go to the charging station to charge the power battery. In the case of a low charging rate, it will affect the performance of the electric vehicle. driving ...

AI Technical Summary

Problems solved by technology

[0005] 1. There is only one power battery pack inside the electric vehicle, and the user cannot expand the power battery;

[0006] 2. When the remaining power of the electric vehicle is low, the user cannot quickly complete the power supply
