Abstract

The invention discloses a power battery system integrating charging and swapping, a working method and an application thereof, comprising a fixed power battery pack and at least one swapping power battery pack, the power output terminals of the fixed power battery pack and the swapping power battery pack are both connected To the power input end of the driving motor, the power output ends of the two are also connected to the power input end of the auxiliary power supply through the DCDC module, and the power output ends of the auxiliary power supply are respectively connected to the fixed power battery management system and the replacement power battery management system As well as the power input terminal of the main controller, it can realize the rapid power replenishment of electric vehicles or the expansion of power battery packs, increase the mileage of electric vehicles, relieve mileage anxiety, and improve the driving experience.

Description

Technical field[0001]The invention belongs to the technical field of electric vehicles, and specifically relates to a power battery system with integrated charging and replacement, and a working method and application.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, which is generally expressed as a percentage. Because electric vehicles use different power devices from traditional fuel vehicles, the internal space of electric vehicles has advantages compared with traditional vehicles. For example, Tesla and other vehicles have a large storage space.[0003]Existing pure electric vehicles usually have a fixed power battery installed in the chassis position. When the battery energy is about to be used up, users can only choose to go to the charging station to charge the power battery. In the case of low charging rate, it will affect the performance of electric vehicles. Driving experie...
