Abstract

The invention provides a networked charging system, and belongs to the field of charging equipment. The networked charging system comprises an 220V input interface, a full-bridge rectifier and filter circuit, a power switch, a high-frequency transformer, a rectifier and filter circuit, a special electric meter for charging, 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. The input end of the 220V input interface is connected with a mains supply, and the output end of the220V input interface is connected with the full-bridge rectifier and filter circuit. The output end of the full-bridge rectifier and filter circuit is connected with the special electric meter for charging through the power switch, the high-frequency transformer and the rectifier and filter circuit. The output end of the special electric meter for charging is connected with an external rechargeable battery. The input ends of the voltage and current sensor and the temperature sensor are connected with the external rechargeable battery, and the output ends 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 systems, in particular to a networked charging system. 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 charging station based on I...
