Abstract

The invention discloses an internet-based electric vehicle charging station and belongs to the field of charging equipment. The internet-based electric vehicle charging station comprises a 220V input port, a full-bridge rectification and filtration circuit, a power switch, a high-frequency transformer, a rectification and filtration circuit, a special charging ammeter, an optical coupling isolator, a controller circuit, a voltage and current sensor, a temperature sensor, a gateway, an internet data center and a display circuit, wherein an input end of the 220V input port is connected with a mains supply, an output end of the 220V input port is connected with the full-bridge rectification and filtration circuit, and an output end of the full-bridge rectification and filtration circuit is connected with the special charging ammeter through the power switch, the high-frequency transformer and the rectification and filtration circuit. An output end of the special charging ammeter is connected with an external rechargeable battery; input ends of the voltage and current sensor and the temperature sensor are connected with the external rechargeable battery, and output ends of the voltage and current sensor and the temperature sensor are connected with the controller circuit; the controller circuit is connected with the internet data center through the gateway.

Description

technical field [0001] The invention relates to the field of charging equipment, in particular to an Internet-based electric vehicle charging station. Background technique [0002] Batteries are the key power output units of electric vehicles. Among several commonly used batteries such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries and fuel cells, because of their large energy ratio, light weight, good temperature characteristics, and low pollution , memory effect is not obvious and other characteristics, lead-acid batteries, nickel metal hydride batteries are widely used in electric vehicles. However, due to the incorrect charging method, the service life of the rechargeable battery is far below the specified life. That is to say, many batteries are not used up but charged up. It can be seen that the quality of the charger has a great impact on the battery life. Therefore, it is necessary to design an electric vehicle c...
