Intelligent electric vehicle charging pile capable of improving equipment utilization rate

Abstract

The invention discloses an intelligent electric vehicle charging pile capable of improving the equipment utilization rate. The charging pile comprises a pile body, a load monitoring device, a load control device, a metering device and an electric vehicle battery power management module, and is characterized in that the load monitoring device is used for monitoring the load of a charging pile powersupply area; the load control module is used for adjusting the load of a branch line of each charging pile; the metering device is used for metering electric quantity of each branch of the charging pile; the electric vehicle battery power management module is used for detecting the power condition of an electric vehicle connected with each charging pile; the pile body is used for connecting the electric vehicle with a power grid to charge the electric vehicle. The charging pile has the functions of load monitoring, adjustment and electric vehicle electric quantity management, avoids the overload of lines and distribution transformers during peak power utilization, improves the efficiency of the charging piles, and reasonably allocates the charging time of each charging pile.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle intelligent charging pile for improving equipment utilization. Background technique [0002] In recent years, the development of new energy vehicles is an inevitable trend in the development of the automobile industry, and intelligence, environmental protection, and energy saving will be the general trend of automobile development. As the number of electric vehicles continues to increase, the safety and reliability of the power grid has also been tested. Due to the increase in the number of charging piles, the distribution transformers in some station areas are old equipment or the connection of charging piles was not considered during planning and construction. As a result, the capacity of the distribution transformer cannot afford the simultaneous charging of the charging piles it carries, and the distribution transformer is overloaded. , ...
