Photovoltaic off-grid charging system for electric car

Abstract

The invention discloses a photovoltaic off-grid charging station system for an electric car, which consists of a photovoltaic component array system, a photovoltaic controller, an energy storage battery system, a component and environment monitoring system, a charger array and control system, and a commercial power emergency charging system, and can be used for golf battery cars, electric buses and other electric cars. The photovoltaic component array system mainly completes converting solar energy into direct current; a charging controller realizes the reasonable distribution of electrical power; the charger array and control system is connected between the photovoltaic component array system and the electric car for charging a battery of the electric car; the energy storage battery system is mainly used for storing the electrical power generated by a photovoltaic component, and charges the electric car under the conditions of overload or insufficient continuous sunshine; and the commercial power charging system is mainly used for solving the problems of time limit and amount limit of photovoltaic electrical power. The photovoltaic off-grid charging station for the electric car can realize the charging organization and management of a plurality of electric cars of different types produced by different producers.

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 utilizing off-grid power generation of photovoltaic modules. Background technique [0002] At present, the global energy shortage, automobile is an important field of energy consumption. The development and promotion of electric vehicles is of great significance to the realization of energy diversification and sustainable development. The field of automobile 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 stations are an important infrastructure for the industrialization and commercial operation of electric vehicles. With the increasing use of electric vehicles on the market, when they are charged at ...

[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
