Abstract

The present invention provides a vehicle charging control structure and strategy that combines external ambient temperature and terminal temperature rise temperature, uses an external temperature sensor, connects the temperature sensor module to a designated position, and transmits the temperature signal of the temperature sensor to the battery control The battery control box detects the state of external temperature changes through temperature detection during the charging process, combined with the temperature rise of the internal terminals, corrects the required current of the battery control box according to the internal and external temperature, thereby reducing terminal overheating to a certain extent In most cases, heat balance at a lower temperature can be generated, thereby ensuring the quality of the terminal, prolonging the service life of the terminal, making it impossible to stop charging, reducing the charging time and improving the vehicle's performance. safety.

Description

technical field [0001] The invention relates to the technical design field of pure electric vehicle charging, in particular to a vehicle charging control strategy combining external ambient temperature and terminal temperature rise temperature. Background technique [0002] The charging current of the pure electric bus is output based on the combination of the temperature of the battery cell and the SOC of the battery. During the period, the terminal condition of the charging socket is not considered. If the terminal temperature is too high, it will not only cause the jump gun and cannot continue to charge, etc. , and even worse, it may cause the terminals of the charging base and the charging gun to melt, resulting in irreversible adverse effects, which will bring a great test to the safety of the electric vehicle. If the charging current can be corrected to a certain extent in combination with the temperature of the terminal, the number of over-temperatures of the terminal...
