Abstract:With the implementation of a series of preferential policies, the number of electric vehicles will gradually increase. It has been loaded into an optimum design of charging control system under multi-factors from the inquiry of battery charging characteristic itself in the past about issues of charging an electric vehicle. For the affordability of the battery’s physical characteristics itself, the charger’s output power, the transmission grid’s capacity, the owners’ charging requirements and other factors, this paper designs the multi-objective ordered charging control system. It is capable of intelligently control vehicle charging according to the battery’s own characteristics and the environment situation. It uses a method which combines scan cycle monitoring with collaborative adjustment circuit. Under the premise of ensuring the charging process security, weighted operator is introduced in order to satisfy the needs of different user charging. With the progress of related technologies and devices, the system will gradually evolve towards small and micro portable products, which has a very broad application prospects.
