Abstract

The invention provides a power battery and high-voltage distribution box integrated control system for a blade electric vehicle. The system comprises a battery pack lower shell box with a battery pack internally installed. The battery pack lower shell box seals the battery pack through a battery pack upper shell cover and a battery pack fixing support. A power battery positive electrode and a power battery negative electrode are arranged in the battery pack lower shell box. A manual maintenance power-off switch is arranged between the power battery positive electrode and the power battery negative electrode. The power battery positive electrode is connected with the contact switch input end of an MCU pre-charging relay, the contact switch input end of a quick charging relay, the contact switch input end of a general positive relay, the contact switch input end of a slow charging relay and the contact switch input end of an electric heating relay in parallel through wires. The power battery negative electrode is connected with the contact switch input end of a general negative relay. The power battery and high-voltage distribution box integrated control system has the beneficial effects that the production cost of the electric vehicle can be reduced, the dead weight of the electric vehicle is reduced, and the installation space of the electric vehicle is saved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an integrated control system of a pure electric vehicle power battery and a high-voltage distribution box. Background technique [0002] By 2016, with the year-by-year reduction of state subsidies for electric vehicles, the entire field of electric vehicles has higher and higher requirements for vehicle cost control. In an increasingly competitive market, if electric vehicles cannot maintain their economic and practical value , is very difficult to survive; so far, while ensuring vehicle safety, reducing costs has become an urgent task for every car factory. After a long period of research and comparison, we found that the cost difference between electric vehicles and traditional gasoline vehicles is mainly due to the high cost of new energy components added to replace traditional gasoline vehicle engines. [0003] The high-voltage part involved in new ener...
