Problems solved by technology
However, due to the wide variety of charging piles, various brands and models, the charging control principle of the existing battery management system cannot match various charging piles. For example, the voltage required by the battery management system is 24V, and some charging The power supply voltage of the gun is 12V, which leads to the fact that only the specific charging pile that matches it can be selected for charging, which affects the charging efficiency

The invention provides a charging control circuit of an electric vehicle. The charging control circuit is applied to the electric vehicle. The electric vehicle comprises a battery pack. The charging control circuit of the electric vehicle comprises a main control module, a complete vehicle power source, a battery positive power source, a charging base module and a relay, wherein the main control module is used for managing the battery pack and receiving voltage output from the complete vehicle power source or the battery positive power source; the charging base module is used for being in inserting connection with a charging gun so as to charge the battery pack; and the relay is connected with the main control module, the complete vehicle power source, the battery positive power source and the charging base module respectively. When the charging gun is not in inserting connection with the charging base module, the replay provides the voltage output from the complete vehicle power source for the main control module; and when the charging gun is in inserting connection with the charging base module, the relay provides the voltage output from the battery positive power source for the main control module. The charging control circuit of the electric vehicle provided by the invention can be matched with various charging piles, and further the charging efficiency is improved.
Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle charging control circuit. [0003] 【Background technique】 [0004] Due to the consumption of petroleum resources and the pollution of the atmospheric environment, electric vehicles have attracted widespread attention from the society. An electric vehicle includes a battery pack to provide power and a battery management system to manage the battery pack. When the power of the battery pack is too low, it needs to be charged through an external charging pile to provide power for the electric vehicle again. [0005] The current charging method is that when the charging gun of the charging pile is inserted into the charging stand of the electric vehicle, the power supply of the charging pile gun directly supplies power to the battery management system. However, due to the wide variety of charging piles, various brands and models, the charging con...
