Abstract

The invention provides a charging control method and system for a vehicular charger. The method includes: acquiring current charging demanded power, comparing the current charging demanded power with last output power of the vehicular charger, and if the current charging demanded power is equal to the last output power of the vehicular charger, determining whether or not a current temperature of the vehicular charger is in a temperature protection threshold range; if yes, determining that the current output power of the vehicular charger is the current charging demanded power; if the current charging demanded power is different from the last output power of the vehicular charger or if the current temperature of the vehicular charger is not in the temperature protection threshold range, calculating a power difference between the current charging demanded power and the last output power of the vehicular charger, using the power difference and the current temperature of the vehicular charger as input, and using a fuzzy algorithm to calculate the current output power of the vehicular charger and outputting the current output power.

Description

technical field [0001] The invention relates to the field of chargers, in particular to a charging control method and system for a vehicle-mounted charger. Background technique [0002] With the depletion of non-renewable resources such as oil and the increasingly serious environmental pollution, the vigorous development of the pure electric vehicle business is undoubtedly an important means to effectively alleviate the energy crisis and environmental problems. Pure electric vehicles have the advantages of zero emissions, high efficiency, and low noise. [0003] At present, the charging system of pure electric vehicles generally consists of on-board chargers, batteries and their management systems (BMS), charging piles, high-voltage lines, etc. They communicate through the CAN bus. The charger receives the 220V AC power of the charging pile, and through the rectification circuit, it becomes 320V (the platform voltage of the battery) high-voltage DC power to charge the batt...
