Abstract

The invention discloses a current-charging-and-alternating integrated power battery system and a working method and an application thereof. The current-charging-and-alternating integrated power battery system comprises a fixing power battery pack and at least one alternating power battery pack, and power output terminals of the fixing power battery pack and the alternating power battery packs are connected with power input terminal of a driving motor and are further connected to power input terminals of a BMS power supply through a DCDC module at the same time; and the power output terminals of the BMS power supply are correspondingly connected to a fixing power battery management system, an alternating power battery management system and a main controller. The current-charging-and-alternating integrated power battery system can be applied to realize quick recharging of an electric vehicle or expansion of the power battery pack, the running mileage of the electric vehicle is increased, and mileage anxiety is relieved.

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, 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...
