Abstract

The invention discloses a multi-gun simultaneous charging system applied to an electric vehicle. The multi-gun simultaneous charging system comprises at least one type of charging piles, wherein eachcharging pile is configured with a master-slave gun determination function and a master-slave gun power control function; the master-slave gun determining function and the master-slave gun power control function are triggered in a multi-gun same-vehicle charging mode; the master-slave gun determination function comprises: determining a master charging gun and a slave charging gun from all chargingguns currently connected to the electric vehicle based on a trigger instruction of the charging guns, keeping the master charging gun to communicate with the electric vehicle, and disconnecting communication of the slave charging gun from the electric vehicle; the master-slave gun power control function comprises the steps of controlling the output power of the master charging gun and the slave charging gun during charging, keeping the master charging gun as a master output charging gun and always outputting power in the charging process, and keeping the slave charging gun as an auxiliary output charging gun. The multi-gun charging method provided by the invention is beneficial to reducing energy loss and improving the energy utilization rate.

Description

technical field [0001] The present application relates to the field of electric vehicle charging, in particular to a multi-gun simultaneous charging and charging system applied to electric vehicles. Background technique [0002] With the development of science and technology, electric vehicles have been widely used because of their energy saving and environmental protection characteristics. Electric vehicles usually use conventional charging methods to supplement their electricity, which can effectively reduce their dependence on petroleum resources. [0003] In the prior art, in order to improve the charging efficiency of an electric vehicle, a method of jointly charging multiple charging guns is usually used to charge the electric vehicle. However, automatic power distribution to each charging gun cannot be realized, and each charging gun usually continuously outputs at a fixed rated power, which easily causes energy loss and low energy utilization efficiency.
