Abstract

The invention discloses a power battery system with integrated rechargeable and changeable batteries, a working method, and applications. The system comprises a fixed power battery pack and at least achangeable power battery pack. Power output ends of the fixed power battery pack and the changeable power battery packs are connected with a power input end of a drive motor, and the power output ends of the fixed power battery pack and the changeable power battery packs are also connected with a power input end of an auxiliary source power supply through a DCDC module. The power output end of the auxiliary source power supply is connected with power input ends of a fixed power battery management system, a changeable power battery management system, and a main controller, to realize fast charging of an electric vehicle or expansion of a power battery pack, and improve road haul of the electric vehicle, relieve range anxiety, and improve driving experience.

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. 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, generally expressed in percentage. Because electric vehicles use different power devices from traditional fuel vehicles, the interior 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 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 experie...
