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, and at the same time connected to the power input end of the auxiliary power supply through the DCDC module, the power output end of the auxiliary power supply is respectively connected to the power of the fixed power battery management system, the replacement power battery management system and the main controller At the input end, the main controller interacts with the fixed power battery management system, the replacement power battery management system and the DCDC module respectively, the fixed power battery management system interacts with the fixed power battery pack, and the replacement power battery management system interacts with the replacement power battery. Group information interaction can realize rapid power replenishment of electric vehicles or expansion of power battery packs, increase the mileage of electric vehicles, relieve mileage 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 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 ...
