External interface connection device of electric vehicle built-in battery

Abstract

The present invention provides an external interface connection device of an electric vehicle built-in battery. The external interface connection device includes an electric vehicle built-in battery interface which is connected into an electric vehicle charging interface, an electricity taking / charging interface which is used for connecting an external power source or an electricity consumption device, a control board which is connected between the electric vehicle built-in battery interface and the electricity taking / charging interface and simulates a charging communication protocol so as to make a built-in battery management system switch on an electric switch between the electric vehicle built-in battery and the charging interface. With the external interface connection device of the electric vehicle built-in battery adopted, not only can the conventional charging action of the electric vehicle built-in battery be realized, but also the electricity taking of the electric vehicle built-in battery can be realized, and therefore, the electric vehicle built-in battery can be adopted as a mobile power supply device so as to be used by an external electricity consumption device, and therefore, electricity consumption problems in outdoor conditions or remote areas can be solved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of interfaces of built-in batteries of electric vehicles, in particular to an external interface connection device for built-in batteries of electric vehicles. [0003] 【Background technique】 [0004] In outdoor or remote areas, electric energy may be missing or insufficiently supplied, thereby affecting people's quality of life and user experience. The built-in battery of electric vehicles has a large capacity, and there is still a large amount of available electric energy after long-distance transportation. It can be regarded as a mobile power supply station. [0005] According to the requirements of the national standard GB / T 18487.1-2015 on the battery interface of electric vehicles, there is an electrical switch connected between the built-in battery of the electric vehicle and the charging interface, which is usually disconnected, which makes the built-in battery of the electric vehicle cannot be used as...
