Abstract

The invention provides a control device for switching and charging an electric vehicle battery, and belongs to the field of electric power control. The device solves the problem of the slow charging speed of the traditional electric car battery. The technical key points includes the following content: the device converts 220V AC power to DC voltage to supply power to a single chip and batteries simultaneously; a battery life checking module and a battery lock which are located in a battery cylinder are connected with a directive input end and a directive output end of the single chip through relays; the single chip checks the putting-in and taking-away of batteries in the battery cylinder through checking the battery voltage; if a battery is put in the battery cylinder, the user swipes a card, a main control single chip reads an ID number of the card through an RFID card reader; if the ID identification is successful, an electrically controlled lock is controlled through a relay to lock the battery which is just put in the battery cylinder, at the same time, a fully charged battery is released, a corresponding charging switch is closed to charge the battery; if the identification fails, the card swiping operation is invalid. The control device for switching and charging electric vehicle battery can be used in urban areas and residential areas, wherein batteries can be replaced by fully charged batteries to continue driving in the manner of battery lease.

Description

technical field [0001] The invention relates to a control device for exchanging battery life and charging of an electric vehicle, belonging to the field of electric power control. Background technique [0002] With the shortage of world oil resources and the serious situation of global warming, the construction of low-carbon vehicles will become the development direction of the new energy industry. At present, the research on electric vehicles in the world has entered a white-hot stage, and people have made it the mainstream of the 21st century. Electric vehicle charging facilities are an indispensable and important part of the electric vehicle industry chain. While vigorously developing the electric vehicle industry, we should also fully consider the development of electric vehicle battery exchange life and charging control facilities. Therefore, the research on electric vehicle battery exchange life and charging control devices is very important. However, the current sma...
