Photovoltaic parallel grid charging system for electric car

Abstract

The invention discloses a photovoltaic parallel grid charging system for an electric car, which comprises a photovoltaic component array, a parallel grid inverter, a component and environment monitoring system, a transformer, a power distribution cabinet, a meter, a charging control system, a charging monitoring system and a charger, and can be applied to golf battery cars, electric buses and other electric car charging stations. The charging control system can control an access number and an access sequence of the charger to realize the charging management of the electric car. The charging monitoring system monitors the charging information of a battery over and again and displays the charging states of all accessed electric car battery packs. The charger completes detailed charging control and overcharge protection of the electric car battery packs. An electric car photovoltaic parallel grid charging station can realize the charging organization and management of a plurality of electric cars of different types produced by different producers, and can realize quick charging, pure solar energy charging and other charging forms for the electric cars.

Description

technical field [0001] The invention relates to a charging system for electric vehicles, in particular to a charging system for charging electric vehicles by using photovoltaic components to connect to the grid to generate electricity. Background technique [0002] At present, there is a shortage of global energy, and automobiles are an important area of ​​energy consumption. The development and promotion of electric vehicles is of great significance to the realization of energy diversification and sustainable development. The automotive industry and major industrial countries attach great importance to the development of electric vehicles. my country has included the development of electric vehicles in the key areas of the national medium and long-term development strategy. Electric vehicle charging station is an important infrastructure for the industrialization and commercial operation of electric vehicles. With the increasing use of electric vehicles on the market, wh...

[0003] Invention patent 200610062677.3 discloses a charging system for electric vehicles. However, this system uses commercial power charging. Invention patent 200710118518.5 discloses a charging operation method for electric vehicles. The charging station involved can use commercial power or solar energy. Charging for cars, but this invention does not solve the problem of charging organization and management under the operation of multiple vehicles and multiple power supply systems, especially there is no system solution for the characteristics of solar energy

At the same time, until now, there is no real photovoltaic charging station for electric vehicles in my country. It is different from the traditional mains charging station and has special technical requirements and characteristics: on the one hand, solar power has its own characteristics, For example, it is easy to be affected by the environment and unstable; on the other hand, the charging station should not be a simple collection of multiple chargers, but should be a charging and management system for different electric vehicles and different battery packs
