Embodiment Construction

[0030] To solve the problem of charging and swapping electric vehicles that can be popularized, a more effective way is to arrange charging stations at a certain density, and the charging stations can be powered by dedicated lines to reduce the impact on the power grid. The charging station works continuously to charge the battery continuously. The battery of the electric vehicle is replaceable. When the battery of the electric vehicle is exhausted, the electric vehicle goes to the charging station to replace the battery. This solves the problems of the efficiency of the charging station, the safety of the grid operation and the convenience of battery replacement. In order to meet the different endurance requirements of electric vehicles, electric vehicles can be equipped with battery compartments that do not pass specifications, and various battery combinations can be used to meet different endurance requirements. Correspondingly, electric vehicles also have functions such as...

Abstract

The invention discloses a charging framework for an electric vehicle. The charging framework for the electric vehicle comprises a battery pack, an electric energy distributor, a running driving unit and low voltage electric equipment. The battery pack comprises a main battery, a range-extending battery and a sub battery; the main battery provides electric energy needed by daily running of the electric vehicle; the range-extending battery provides electric energy needed by ultra-long distance running of the electric vehicle; and the sub battery provides electric energy needed by emergency short-distance running of the electric vehicle, wherein the main battery and the range-extending battery cannot be charged on the electric vehicle but can be replaced; and the sub battery can be charged on the electric vehicle but cannot be replaced. The main battery and the range-extending battery output electric current to the electric energy distributor; and double-way electric current is available between the electric energy distributor and the sub battery. The running driving unit is used for driving the electric vehicle to run; and double-way electric current is available between the electric energy distributor and the running driving unit. The electric energy distributor is used for outputting electric current to the low voltage electric equipment; and the electric current output by the electric energy distributor is used for driving the low voltage electric equipment to work after the voltage of the electric current is converted. The invention further discloses a battery replacing method for the electric vehicle.

Description

Technical field [0001] The present invention relates to the field of electric vehicles, and more specifically, to a structure and method for charging and replacing electric vehicles. Background technique [0002] Whether for traditional internal combustion engine vehicles or electric vehicles, endurance, that is, the continued driving history of a full tank of fuel or a full charge is a key indicator that users pay attention to. At present, it is generally accepted that gasoline vehicles can travel 350-500km with a full tank of fuel. Therefore, for electric vehicles, users naturally hope to have similar driving history indicators, that is, they can drive at least 350km at full load with one charge. According to the driving efficiency of 5km on 1 kilowatt-hour, the electric vehicle battery needs to be able to hold 70-100 kilowatt-hours of electricity. For a battery with a capacity of 70 to 100 degrees, if a slow charging mode is used, such as a 7-hour full charge, the effective c...
