Abstract

The invention relates to an intelligent detection method for a vehicle-mounted charger. The method comprises the following steps: (1), transmitting a charging instruction to a charger through a battery management module; (2), collecting direct-current side voltage and current of the charger, and voltage, current and charging state information detected by the charger; (3), carrying out processing according to the collected charging state information for generation of first processing data, and detecting the current working state of the charger by combining preset parameters with the collected data; and (4), collecting alternating current side voltage and current of the charger, processing the alternating current side voltage and current for generation of second processing data, so as to detect alternating current side electric parameters of the charger, simultaneously comparing the second processing data with the first processing data, and obtaining the output efficiency of an off-board charger, so as to detect tractor parameters of the charger. According to the intelligent detection method for the vehicle-mounted charger, automatic detection on field functions of the charger which is arranged in a charging station or an electrical changing station can be realized; and safe operation of the charging station and the electrical changing station for an electric car is ensured.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to an intelligent detection method for a vehicle-mounted charger. Background technique [0002] At present, due to the advantages of electric vehicles in energy saving and environmental protection, my country has taken the development of electric vehicles as an effective means to solve urban air pollution and energy problems. There are two ways to replenish electric energy for electric vehicles: vehicle charging and battery replacement. Vehicle charging is the electric energy supply of electric vehicles in the charging station through charging piles in the form of DC or AC; battery replacement is the special replacement of electric vehicles in the battery replacement station. The device replaces the exhausted battery pack and replaces another set of fully charged batteries, uses the transfer mechanism to transport the exhausted battery pack to the battery charging rack, and uses th...
